From the Document: "On January 27, 2021, President Biden signed Executive Order 14008, which expressed the intent to 'put the United States on a path to achieve net-zero emissions, economy-wide, by no later than 2050.' A number of other countries, as well as cities, regions, and companies, have also made 'net-zero' emissions pledges. This In Focus explains the concept of net-zero emissions, identifies recent net-zero pledges, and presents a series of questions to consider when examining net-zero pledges. This In Focus does not address or evaluate the challenges involved in achieving net-zero targets or the technological advances and/or policy options that would likely be needed to reach them."
