; and (B) the current capacity of each country to both mitigate greenhouse gas emissions and adapt to climate impacts; (14) developed countries that have historically emitted a disproportionately high share of greenhouse gas emissions, and reaped the economic benefits of those polluting activities, have a corresponding and disproportionately greater responsibility to engage in global mitigation and adaptation activities than less industrialized countries that have historically polluted far less; (15) the only realistic way for less industrialized countries to meet their full mitigation potential is through international climate financing by more developed countries; (16) in the 2009 Copenhagen Accord, developed countries committed to jointly mobilize, starting in 2020, $100,000,000,000 per year in public climate financing (as well as private investments and other alternative forms of finance) for developing countries, a commitment reaffirmed in 2015 in Decision 1/CP.21 of the United Nations Framework Convention on Climate Change, Adoption of the Paris Agreement; (17) the $100,000,000, commitment described in paragraph (16) was a political compromise that falls short of the actual financing needs for climate action in developing countries; (18) Bloomberg New Energy Finance has estimated that the transition to renewable energy sources in developing countries will require hundreds of billions of dollars annually; (19) the United Nations Environment Programme has estimated that adaptation needs relating to climate change in developing countries may be as much as $300,000,000,000 annually by 2030; (20) the Green Climate Fund was created in 2010 by 194 countries to serve as a crucial financing mechanism to help developing countries limit or reduce greenhouse gas emissions and adapt to climate change
