For Earth Day 2026, USA TODAY has revealed its fourth-annual America's Climate Leaders list, highlighting 500 U.S. companies that are reducing their greenhouse gas emissions. The list is ranked based on criteria such as emission intensity, reduction rates, and carbon disclosure ratings. This year's top companies include technology company RAMBUS, furniture company The Lovesac Company, and fintech company Tradeweb Markets, which reduced their core emissions by more than 90% year-over-year. The financial benefits of reducing emissions can lower costs and attract new customers, according to a 2025 report by Boston Consulting Group. Companies that promote green initiatives and increase efforts to tackle climate change receive economic benefits from decarbonization.
