In April 2019, Manchin was the only Democrat to cosponsor the Enhancing Fossil Fuel Energy Carbon Technology (EFFECT) Act, legislation intended to increase federal funding for developing carbon capture technology and simultaneously commit to fossil fuel use. In a statement, he cited the need for the United States "to lead in technological innovations designed to reduce carbon emissions" while noting that energy experts who had testified before the Senate Committee on Energy and Natural Resources had concurred on the continued use of fossil fuels through 2040. He called the bill "a critical piece of the solution addressing the climate crisis."
