On December 8, 2021, President Joseph Biden signed an Executive Order (EO) on Catalyzing Clean Energy Industries and Jobs Through Federal Sustainability. The EO calls for the federal government to achieve a carbon pollution-free electricity sector by 2035 and net-zero emissions economy-wide by no later than 2050. Using a whole-of-government approach, the federal government “will demonstrate how innovation and environmental stewardship can protect our planet, safeguard Federal investments against the effects of climate change, respond to the needs of all of America’s communities, and expand American technologies, industries, and jobs.” The EO directs agencies to “incentivize markets for sustainable products and services by prioritizing products that can be reused, refurbished, or recycled; maximizing environmental benefits and cost savings through use of full lifecycle cost methodologies; purchasing products that contain recycled content, are biobased, or are energy and water efficient, in accordance with relevant statutory requirements; and, to the maximum extent practicable, purchasing sustainable products and services identified or recommended by” the U.S. Environmental Protection Agency (EPA). According to the fact sheet, sustainable products include “products without added perfluoroalkyl or polyfluoroalkyl substances (PFAS).”
