It is unlikely that you know how much carbon was produced by making your driveway. But if you did, you might think about ways to build it better.
That is the concept behind the “Buy Clean Colorado” legislation signed into law July 6 by Colorado Gov. Jared Polis. Under the new law, future public construction projects will have to meet clear environmental criteria for the use of seven common construction materials.
With the passage of HB21-1303: Global Warming Potential for Public Project Materials (the formal name of the Buy Clean Colorado legislation), Colorado joins a growing group of states pursuing an untapped opportunity for carbon reductions: The carbon “embodied” in public buildings and roads. With a goal to reduce emissions by 50 percent by 2030 and 90 percent by 2050, Colorado has some of the most ambitious climate goals among U.S. states. This legislation will help the state to meet these bold targets.
