We build reliable, sector-by-sector, year-by-year energy system blueprints – Deep Decarbonization Pathways – for reducing emissions by at least 80% by 2050, while maintaining a thriving economy. Our tools, data and analysis are used at the national, state and city level, where we empower agencies, regulators and other stakeholders to take effective action against climate change. We help turn climate goals into effective climate plans.
