Good to go. Excellent. Okay. Well, thank you everyone on the line for joining us. Thank you to the precast industry for inviting me to introduce you to environmental product declarations for EPDs. I know you've heard about EPDs so my objective here is to help demystify them and hopefully help you see how to get some use from them. I'll just advance the slide here. Just very quickly to reinforce what Brenda just said about the organization I'm coming from. The Athena Institute is a non-profit group that's been around almost 20 years working in the area of life cycle assessment or LCA and that's the science that we use to address environmental footprint. We work with industry to measure and reduce the footprint of their products and then we take the data and we embed it in free software tools to the design community so they can reduce the environmental footprint of their products. What I'd like to cover today, I'm going to do this webinar in four parts. I'd like to first start very high level with the big picture. So high level context about EPDs, what they're all about, what their purpose is. Then let's take a look inside and we'll get into some of the details in an EPD. Third I would like to talk to you a bit about what's driving the marketplace for EPDs in particular, that's a new credit and lead. Then let's end with a little look at what the manufacturer has to go through in creating EPDs. We'll start with that high level introduction to EPDs and as I go through this webinar I'm going to show you a number of examples of EPDs from the precast industry and from others so we get a sense of what these things look like. So starting very, very high level about the purpose of an EPD. An EPD really is a communication tool and the whole point of it is that it's based on data. So EPDs really are a paradigm shift in how industry talks about the environmental attributes of its products and really it's the outcome of a transition or an evolution in the questions that we're all asking about what makes something green. So it's really less of the green wash, if you will, less of the non-substantiated sort of claims that we might see in a logo like what's on the screen on the left and more towards data. So a statement of performance data of a product. That fundamentally is what EPDs are all about and let me further explain that by putting that within the context of other sorts of equal labels or environmental based communication. So in the world of international standards, equal labels fall into three categories. We have type one, two, and three and type one is something that we've all seen a lot of. These are third party certifications. Basically a third party has established a set of criteria and if a product meets the criteria the third party will give it basically a seal of approval and these kind of certifications typically involve a logo. The second category is what's called type two or self-declarations and that's where manufacturers simply state, they simply declare a particular environmental performance attribute or a presumed benefit or characteristic. So the third type here is a very different approach. So type three equal labels are environmental product declarations, EPDs, and they are not a certification, they are not a statement about environmental goodness, it is simply a statement of environmental facts and that brings with it a number of benefits. Now bearing in mind that third party programs, the ones with the logos that seal of approval approach are really valuable because they're easy and they're useful and no one has the sort of time required to perhaps sift through all the environmental claims of manufacturers so it's quite convenient to have someone else make that decision for us but that comes at a bit of a price and that's where EPDs are trying to step in. So the benefits of EPDs are I think fall into the three baskets I've put on the screen here. First they're unbiased because they're not expressing a judgment, they're not expressing opinion, they're simply presenting the data. Second, they're completely transparent and that is actually one of the intentions is that it's a vehicle for transparent communication of data where third party programs or a manufacturer's self-declaration is typically quite opaque, it's difficult to know what is the backup for that claim. And third, EPDs are widely applicable because they contain a lot of data and because users bring their own judgment criteria when viewing the data therefore I can apply that information across a number of different applications. So those are the sort of the fundamental benefits of EPDs. I thought now it might be interesting and useful to just hear a little bit about where EPDs are coming from. Here in North America they seem fairly new to us but they've in fact been around for quite some time and they've got the heaviest and longest history in Europe. So I'm just going to show you a few samples here from Europe to give you a sense of the different sectors that are into this idea of environmental product declarations. And because they've been around for some time a number of standards have been developed. So international standards within the ISO program for example are helping guide EPDs and also some national standards around EPDs. So here are two for very different types of products. One's for wind power and one is for baths and shower trays and sinks. And then even in the category of food. So a tremendous range of EPDs while in North America it's a trend that's coming up quickly predominantly in the construction sector and we have about 400ish EPDs in North America. I'm showing you just a sample of them here to give you an idea of the flavor of them and the approach. So EPDs are part of an evolution as I mentioned in how society is thinking about environmental impacts and how we're starting to change the way that we make environmentally based decisions. And so I like this as a classic example from our daily lives. So we're confronted with this all the time but do you feel that you know with confidence which one of these grocery bags is the greenest? And we've all got some preconceptions here but we're relying on conventional wisdom and we really can't know for certain without seeing some data, some environmental data about the products. And I can certainly tell you that quite often products that we've all thought were green often aren't as green as we thought. There are a lot of surprises out there and the only way to answer the question is to get our hands on data. Otherwise we're just guessing. So the kind of data that we need, amount of material and energy used, the waste created in making the product, greenhouse gas emissions over the full life cycle of the product so that's making, using, and disposing of the product, water used to make the product, air and water pollution through the whole life cycle, that's the kind of information that I would want to look at in order to make a green choice and so that's what ends up getting reported in an environmental product declaration. So I want to give you a sense on this slide of what that information looks like. So what's the terminology we're talking about and what are the units? And this is the kind of information that's reported in an environmental product declaration and this information comes out of an environmental accounting process called Life Cycle Assessment or LCA. An EPD really is simply a summary of a full LCA study on a product. What that means is that to understand EPDs we have to know a little bit about LCA. It's perhaps something that you've already got an idea of. You've probably encountered the term before. Let me just take this slide to do my little mini LCA 101. So very, very high level. I won't get technical in this webinar. I just want to help paint for you the big picture about what this process is. So LCA is an analytical tool. It's a tool for measuring environmental footprint. It's rigorous. It's scientific accounting essentially of the flows between a product and nature. So at every stage of a product life cycle and that's represented in the diagram across that diagonal line there, the full life cycle of a product. At every stage there, there is a consumption of resources. So there are inputs from nature and there are outputs to nature. So there are emissions to air, land, or water and there are emissions of waste. So in this science we measure all those flows and then we estimate the ultimate environmental impact on air, land, and water due to those interactions with nature. We can do this over the entire life cycle and we would call that a cradle-to-grave life cycle assessment or we do it only over part of the life cycle. Typically we have to do a partial life cycle assessment because we may not know what happens to a product when it leaves the factory. And in that case we would be doing a cradle-to-gate LCA. I just wanted to give you some examples from outside of the construction sector and to let you know that industry often uses LCA to help guide their sustainability business decisions and they've been doing that actually for decades. So these are three great examples of manufacturers that wanted to do what they could to have the most impact, to reduce the impact most from their products and to do that they needed to do LCA on the product. The first example is the folks at Levi's wanted to understand what could they do with jeans to reduce the environmental impact of that product. They used LCA to fully understand that the washing and drying of jeans, so what we would call the use phase in LCA, is the biggest part of jeans footprint. So they now insert a care tag that says wash this less and air dry it if you can. In the middle there, north face, with this fleece jacket, they were looking at incorporating more recycled polyester, they were looking at changing their dyeing process. They could have just done that and just marketed that they had done that, but they took it a little more seriously and wanted to put the numbers behind it so they were quite confident that those were the right choices and they did that so they could quantify the benefits of those changes. My last example here with cold water time, so Procter & Gamble did a similar study as Levi's and they concluded that the use phase of detergent is the biggest problem, so it's actually the hot water usage, the energy used to make hot water. So they tackled the problem and reduced the footprint of their product by formulating the detergent to work well in cold water. So three great examples, there are many, many others from industry that really tell a great story of using data to make business decisions that had a true, verifiable, measurable impact in reducing environmental footprint. We can apply that same principle very, very easily to building products or even at the level of the whole building. So this diagram is sort of the building products and buildings version of the earlier one I showed you where we have the life cycle in a building and we have a consumption of resources in at every life stage and we have emissions coming out. What we do at my organization is we work with industry to do LC on their products so that they can find ways to reduce footprint and we work with the design community so that they can do the same at the level of the whole building. We do that by offering a free software tool called the Impact Estimator for Buildings. So now just taking a look at sort of the pure idea behind using LCA. Really fundamentally it typically is going to come down to wanting to compare two options. So I might be a manufacturer looking at making product formulation changes or perhaps changing an upstream supplier. I might be a building designer looking at different options regarding, for example, what materials I might select or my approach to the design problem. So I'm potentially comparing two choices or maybe I'm comparing one option to an industry average. So this is where we use life cycle assessment and looking at option one versus option two across a variety of LCA metrics as I'm showing here on the horizontal graph and recognizing as well that this is not necessarily as simple which one's better because I'm going to typically have tradeoffs. It might be better – option one might be better in some cases for some metrics and not so much in the next. So what might be the motivations to do this, to get into life cycle assessment? Whether you are a manufacturer or whether you're a design firm, why might you want to get into measuring environmental footprint? I really think that the motivators fall into these four baskets. So first it's corporate responsibility. It's simply wanting to do the right thing. So examining environmental footprint because wanting to get hands on data that will help drive improvements for social good. Second, there might be a very clear business rationale that perhaps there's an ability to cut costs here. A typical example would be maybe there's a carbon tax and I'm hoping to respond to and LCA helps me figure out how to reduce my carbon footprint. Third, life cycle assessment is useful in communication because it is the basis of environmental product declarations. I need to do it if I want to be able to talk about my participation in sustainability. Then finally there's the marketing benefit to create a beneficial corporate image because this is a very proactive area to be working in. It's very leading edge. So being a participant, being a user of life cycle assessment can really differentiate corporate culture and product from competitors. Let me close this section out by flagging for you some limitations. Life cycle assessment measures some important environmental impacts but not all of them. And really it's quite important to bear in mind that it does not replace the metrics for other impacts that we may all deeply care about in sustainability and things like biodiversity and toxicity. So therefore EPDs don't tell the whole story. They tell part of the story and we need to always include other techniques when we're talking about sustainable performance and sustainability strategy. All right, let's jump in now and look at what's in an EPD. I'm showing you a sample here, a page from a typical EPD. Every EPD somewhere in there is going to have some tables of some pretty complex looking information. So I thought that what we would do is jump into an EPD and let's take one of the precast EPDs as a great example. We'll use that as our model to walk through. Different EPDs take different forms. They're all going to look a little different. The data is going to be in a different place inside them. But this one is a good example and we'll use it as one for understanding what are the critical pieces in there and what do we really need to look out for, particularly if we ever want to compare two EPDs sign by sign. So this is a 19-page EPD. I'm just going to show you a few pages that we'll walk through and find those key elements that we want to watch out for. So we'll start with the cover of this document and it's telling us the scope of the EPD at the top. It's very clearly telling me this is a cradle to gate EPD. It's identifying the EPD owners, so three precast trade associations worked together to make this EPD happen. So that's important to know that EPDs is communicating to me that it is adhering with the current international standards around EPDs. That's important for credibility. It identifies the product and it identifies at the bottom the program operator, so that's the third party organization that issued this EPD and had it verified. So we'll take a peek inside and most EPDs have a couple of pages in here of standard information that is important to highlight. So first up there is the PCR, that's the product category rule. And what that is is that's a product specific sort of standard that is setting the guidelines for how all EPDs in this product category, in this type of category, how they should be developed. And it's important that we check that if we compare two similar EPDs, we want to be sure that they follow the same set of rules. EPDs have an expiration date and that's because the industry data underlying them needs to be periodically refreshed so that we know that it's the latest product information. EPD identifies product quantity. It's going to be called either a functional unit or a declared unit and what we really just need to know is how much product do these results refer to. That's really important. We'll talk about that in a second as well. And then finally geographic applicability. EPDs, the data under them typically is only applicable within a specific geographic region. Let me carry on in looking at this upfront information in the EPD and we will see some information about who had a look at it, who verified it, and that's important for credibility. The EPD also gives us reference to the underlying full life cycle assessment or LCA report. That's useful if we ever want to really dig deep into where these numbers came from. So I quite like that in terms of transparency. So let's pop into another page. Every EPD somewhere inside is going to have a table of what's in this product, which is a really nice transparency feature. What are all of the material inputs, the material components in the product and that table will be keyed to that product quantity that was declared early in the document. Okay, so now we're in a section that explains in detail the boundary and this is really important for comparability. Here is the section that very clearly explains what is included in the results section of this EPD and also what's excluded and that happens to be shown on the next page in this EPD. So if you wanted to compare this with a product that seems similar, you would need to look very, very closely at this to be sure that you have an apples to apples comparison. So what is included in here? Because this is a precast EPD, that means this is an EPD for a complete system. It means that this includes reinforcing. I don't know if my pointer shows, but that's indicated quite clearly over here, where for example an EPD for ready-mix concrete won't have that component in it. So really important for comparison that we understand what's included and what isn't. In this case, this EPD, this diagram is also extraordinarily transparent about which part of the boundary was data gathered as part of the LCA primary data gathered from manufacturing facilities, and that's shown in the dashed box here, versus data that was included but was taken from existing sources, so that's just a really nice piece of transparency on the LCA method. And then this EPD goes further with that and has about two pages worth of explanation on the LCA method. Great for transparency, may not have much meaning to non-LCA people, but it's a really nice touch for credibility. And that carries on into the second page. I'm not going to spend much time there. Let's go straight to the heart of the EPD. So finally we land there at the table that every EPD will have of the LCA results. So we're now presented with the data. So our question, of course, will be what does that data mean? So let me hop now to a version of that table that I put together that's a little bit easier to read. Okay, so on this screen I've simplified the table and I made it larger so we can read it. So we see the kind of stuff that's reported in an EPD, as I mentioned before, the summary of the LCA results coming from a very lengthy, very technical report. So the question is now what? What do I do with that? And here's where I'm going to tell you that we need to have some patience while we wait for the EPD world to develop a little bit more and we wait for some of this unfamiliar language to get more useful for us. We also need to wait to have a frame of reference. I'm looking at numbers that without a frame of reference I don't really know if that's a good or bad number. Is that a good result? Don't know yet, right? So what will come later? The benefits yet to come fall into these key points I'd like to share with you. So first what we have in front of us here, we have a benchmark. We have a benchmark for future improvements across the industry because we now have an industry average as well. So individual companies can try and beat this average and there's an extra lead point available for that sort of thing. We'll talk about that in a second. But on its own, the usefulness to a material specifier is a little bit limited right now other than to collect the EPD documents aiming for that lead point. But bear in mind that this was a significant investment from industry. This is a significant commitment from industry to gather the data which they now can make use of internally. Meanwhile, the data is actually useful directly to the design community when we roll that into a whole building life cycle assessment and that's what we do with our software tool and impact estimator. So we're really appreciative of the data being available publicly so we can now make it possible to do environmental footprint measurement at the level of the whole building. But thinking now about, well, okay, that's fine but I kind of want to be able to read that data in the EPD and understand it and that's when I would like to ask you to consider a little bit of the history with food labeling. So we are no longer in a situation where we have to rely on this self-declaration on the front label of the package where the manufacturer is making a statement to us about the performance benefits of the product. We now know that we can turn that package around and we have access to all sorts of other information, other data that might help us make the choice. So we are going to get there eventually with EPDs. As more standardization comes into play, as we get more benchmarking in place, the piece that we're really missing is that percent daily allowance part, that part where I could look at an EPD and say, well, how does this compare to my, say, daily allowance or whatever form that particular benchmark might take. All right. Let's just talk now, though, about whether or not EPDs are comparable. In theory, they should be. That is their intention and that is the purpose of the development of standards under them and the creation of product category rules. But because it's still early days with EPDs, we can't really compare them yet, and I have a nice illustration here to tell you why. So we have here two different EPDs for similar carpet tile products, different manufacturers. So theoretically, I should be able to open those EPDs. I would find that table of results and I should be able to compare them side by side. The fact is, those two sets of results look very different for these. One of these looks a lot worse than the other. That's because we can't really compare these unless we've made sure that the LCA parameters are all the same. So we need to look for all those key features that we just searched for in the pre-CAS DPD. We need to really closely read the study and we need to really have an understanding of what happened with these two LCA studies. In this case, when you do that, if you have the patience to do that and you have the LCA knowledge to know what you're looking for, you will find that these two LCA studies had extremely different timeframes. So one study looked at the carpet just through one year of use and the other looked at the carpet for a 60-year study, which means given the lifespan of carpet tile, that carpet tile was replaced three times. So of course its results are going to look different because it's basically, in this case, comparing one serving of carpet to four servings of carpet. They had different things within the boundary. It's not quite clear whether they were including the same stuff. They had different regimes for cleaning and so on. Unless you looked closely at the whole EPD, you might miss some of the changes. We really need to be careful right now in these early EPD days of looking at things side-by-side. We're not quite there yet in the EPD infrastructure and the standardization. For now, let's just recognize the good work that industry is doing to get this ball rolling and understand that there's still a lot left to come. All right, let's move into part three. I want to talk about what's going on in the marketplace. What's driving industry to produce EPDs other than a sense of corporate responsibility? There are a number of factors, of course, that would drive industry to want to do this, but probably the one factor that's maybe having the most influence right now is leads. I'm going to focus on lead in talking here, but first, let me just give you a snapshot of the global market and what's happening with EPDs. It is an exploding market. I'm showing you a little bit of market information primarily from Europe, but where the EPDs are happening worldwide and how many there are. At the moment, there are well over 2,000 EPDs and increasing really exponentially, so lots of activity. What's driving that in the U.S. and Canada is this new credit in lead version four. Let's just have a little bit of a look at that credit. The credit is called Building Product Disclosure and Optimization, Environmental Product Declarations. This is a new materials and resources credit in lead version four. It's also available in the same form, it's a pilot credit, so it's available outside of lead v4. The intention of this credit is to motivate industry to do LCA and then produce the EPDs. The idea is that the hope there is just to lead industry to environmental improvements. The credit is worth up to two points. I'm going to tell you about those points in a second. Let me just first mention the little PS I put at the bottom of the screen about another new lead v4 credit in the MR section. It's worth at least three points and that is a motivator for doing LCA at the level of the whole building. It's a designer focused credit and the intention is to motivate design teams to reduce the impact of buildings. But sticking here with the EPD credit, if I were to distill that credit down really to its simplest explanation, the idea here is as a design team, if you assemble enough EPDs you can earn one point and then if you assemble enough, quote, good products, there's a second point available. All right, so let's talk about getting that first point, assembling EPDs. So what you need to do is you need to specify at least 20 products with EPDs and you need to have a good representation of different manufacturers, so at least five different manufacturers. Now the pointing on this, the calculation is of course a little complicated. Some EPDs only get partial credit. If you are using an industry average EPD, the precast EPDs or industry averages, I'm showing you one on the screen from the ReadyMix side of the world, that's worth only half a product. So if you only used those kind of EPDs, you would need to have at least 40. The other kind of EPDs are brand name or what LEED's calling product specific EPDs and that's worth full credit and there's an example on the right from ReadyMix, so that's going to get full credit. So that's how the pointing works. So I might, for example, have 15 brand name EPDs and then I maybe have a handful of industry average. If I have 15 brand name, I need five more, but if I'm just going to use industry average for those, I really need 10. So there's the pointing on that. Now this credit is still new enough that they're probably still working on a number of bugs. I would suggest keeping an eye on the LEED credit interpretations to see where there might be some wiggle room or to get better clarity. For example, if you're struggling to get those 20 EPDs, a question that's already come up is, can I count an industry wide EPD more than once and there has been a credit interpretation on that. I've got that on the screen. So good to keep an eye over there with the LEED folks and direct any questions there about whether an EPD counts and how many times it can count, direct it over to the folks at LEED. This credit has the ability to earn a second point and just address that in the slide here. This in my opinion is probably not a reachable credit and won't be for quite some time. It's really an aspirational credit on the part of LEED. So you need to get at least 50% of the value of all installed products that are better than average in at least three LCA metrics or comply with some yet to be developed programs. So the difficulty with this is that's a hugely high bar, 50% of the value of all products need to beat the average and it means that we need to have average data for a lot of products and that's just not in existence right now. For this credit you'll get double credit for local products. The credit has a cap though on the use of structure and envelope products to earn that point. So all of that is really quite a challenge. So I would say maybe keep an eye on what LEED is doing with that. But I do believe, I have a sense that the purpose of this is just to establish the higher bar for industry to reach for. So this is inspiring activity in manufacturers looking ahead. Okay, let's wrap up with my last section and step into the manufacturer's shoes and take a look at what's involved in putting together an EPD. So first I just wanted to give you the big picture of what happens at the national level and that EPDs really do require a substantial amount of infrastructure of sort of centralized or national level infrastructure. We need, first of all, we need a collection of a lot of LCA data on products and processes. We need a lot of standards and the product category rules. We need a network of program operators. We need a network of experts that can verify all of that. So just to give you an idea that this is sort of a big deal and it is a work in progress worldwide. But now looking at a specific example, let's talk about how individual EPDs happen and I will use that. I will use one of the precast EPDs or the three precast EPDs as the example because that really was quite a typical process. So the process starts with a manufacturer or a group of manufacturers and in this case three precast trade associations acted on behalf of the industry and decided that they'd like to do an EPD. So they then need to engage with two other organizations typically. They're going to engage with an LCA practitioner and they will engage with an EPD program operator. So the LCA practitioner was us. It was the Athena Institute. So we conducted an LCA study of this product, published the report. We responded to critical peer review of that report and prepared the content of the EPD and we do all that in accordance with the product category rules and the ISO standards around LCA and around EPDs. And then the EPD program operator, in this case ASTM International, led development of that PCR, the product category rule per ISO standards, had the EPD verified and then they registered the EPD. So it's really quite a lengthy process. It can be expensive. It needs to be repeated every five to ten years to capture any changes in the underlying data. So really it's a lengthy and highly rigorous process, but it's happening within a well-defined system and it involves standards and rules and third party review. And really what that all means is that the end result is highly credible. And the heart of it, the heart of the EPD is that LCA study. So it's someone like the Athena Institute going into manufacturing operations and assessing them. So the EPD then is reflecting actual manufacturing data where we're looking at every step in the facility, like I mentioned before, in the process of LCA. Now for an industry average EPD like the precast EPDs, this is going to happen with a statistically valid sample set. So we don't go into every facility, but we go into a number of facilities in order to adequately capture average precast. And then we produce that LCA. Let me now just take a step up because I would like to put that in the bigger context of sustainability in the construction sector. So beginning here at the top where we've got all kinds of industries, all kinds of manufacturers creating LCA data on products, what then do we do with that in order to help advance sustainability in the entire built environment? Let's first take a look at the right-hand side of the diagram. So the first thing that we can do is we can take that product LCA data and incorporate it in whole building LCA tools so that we enable architects and engineers to do whole building LCA so that we can come up with – so that we can aim for a smaller footprint in buildings or in works of infrastructure and perhaps ultimately earn some points in a green program like LEED. Let's talk now though about the left-hand side of the diagram and what happens with industry. So manufacturers take that LCA data on products. They can now publish it in EPDs and that will end up perhaps being sought for by architects looking to maybe earn that LEED point or looking for EPDs for other reasons. But what's really interesting is when we come down to that blue box on the left and when manufacturers use the LCA data to drive product changes for a smaller footprint, that's really interesting and I would like to share with you what the precast industry is doing along those lines. It's a great case study of industry taking their LCA results and applying it within the manufacturing process. We'll have a few slides to end up with here to close the presentation and a few slides from the precast trade associations to show you to tell that great story of industry participation in a broad-based and proactive sustainability agenda. So the precast industry took the lessons of their LCA and they launched a whole program that they call the Sustainable Plant Program, which is a program that is designed to encourage continuous improvement along of course with compliance with environmental regulations and standards, but it's all about tracking the things that were identified in the LCA as environmental hotspots and tracking all the other environmental metrics as well, tracking it in order to seek opportunities for improvement and in order to provide a reporting mechanism. So this is a voluntary program. It's not replacing any of the regulatory reporting requirements for this industry and manufacturers are still staying on top of that of course. But this program is designed to track improvements and facilities are submitting confidential benchmark reports on a quarterly basis and the aggregated results of that program are communicated to the public through each association's sustainability reports. Here's an example for you from the one from the Canadian Precast Group. The heart of the program is a nice little web-based software tool that the plants can use to track environmental performance measures and monitor their changes and so forth. We were really pleased to work with the precast industry to help put that tool in place for them. All right, so let's just close with a summary of the key points that I would love if you walked away with. First, an EPD is a summary of a much more extensive underlying LCA report. EPDs are transparent, they're non-judgmental, they're intended as communication vehicles. LCA measures some but not all environmental impacts. LCA is really important for supporting data-driven sustainability choices, it is the data. LEAD is trying to motivate manufacturers and designers to do life cycle assessment in the hope that that will drive smaller footprints in building products and in whole buildings. EPDs, it's still early days, they're not yet comparable and they require specialized knowledge to interpret, but let's not forget that the data behind them is really valuable, really useful, and being applied by industry. All right, I'll just leave you with some contact info for the Athena Institute. We have a lot of resources on our site for understanding LCA, for understanding the LEAD credits related to LCA and all that. So at this point, Brenda, I'm going to stop and see if there are questions or perhaps further comments from the precast.
