Description (excerpt):
When it comes to reducing carbon emissions, we can’t cut what we can’t count, and some of the biggest opportunities to cut carbon are getting lost in the shuffle. With the right tools, we can fix this problem.
Common construction materials used to build our homes, offices, roads, and bridges are a significant source of greenhouse gases, with concrete, steel, and aluminum alone accounting for 18% of global emissions. In order to encourage the use of lower-carbon materials, we need a reliable way to compare products. Fortunately, a disclosure tool called an environmental product declaration (EPD) has emerged in recent years to help measure the climate impact of products and enable consumers to buy cleaner.
An EPD is a report that quantifies the “embodied carbon” of a product, or the emissions generated from mining the raw ingredients, transporting them, running the kiln or furnace to produce the building material, and then using it to construct a road or building. It allows the manufacturers of these materials to report standardized, third-party verified data and enables sustainability-minded buyers to make more informed purchasing decisions. In fact, recent cases have shown that even requiring the disclosure of EPDs, without any further action, reduces embodied emissions by 20%.
