Successfully addressing the climate crisis while achieving sustainable development goals will require carefully constructed strategies to enact rapid economic transitions to a cleaner economy—tailored to national circumstances and priorities. The Center for Global Sustainability has deep expertise in country-specific analytical and policy approaches across key sectors and in support of a 1.5°C-pathway.

The Center for Global Sustainability is the analytical lead for America Is All In a coalition of over 4,000 cities, states, businesses, universities, communities of faith, and others that have pledged their commitment to support the goals of the Paris Agreement. CGS works with U.S. subnational and international partners to deliver analysis that informs how an "all-of-society" climate strategy can drive actionable and feasible policy. CGS informs U.S. climate policy from the local to global through developing integrated modeling and climate scenarios for the federal government, advising on international discussions to ramp up ambition, and collaborating from the bottom up to move the resources necessary to set and achieve ambitious climate goals.

Rising to meet the ambition set out by our global climate commitments demands accelerated actions and commitments between all actors across our society: states, cities, businesses, universities, faith groups, and more. These sum-of-society actors have incredible leverage to impact the trajectory of greenhouse gas emissions, innovate across our economy, and accelerate the speed of the global clean energy transition.
