From the Document: "Congress may continue to examine Clean Air Act (CAA) [hyperlink] authorities and climate change issues as it deliberates on legislation and conducts oversight [hyperlink] of the U.S. Environmental Protection Agency (EPA). The Biden Administration has committed to reducing greenhouse gas (GHG) emissions using various policy tools to achieve a 'carbon pollution-free electricity sector [hyperlink]' by 2035. Multiple factors, including economics, technology, and energy and climate policies, could play a role in future GHG emission levels. Many say both legislative and executive actions would be necessary to decarbonize the electricity sector by the Administration's target date."
