Half of U.S. public companies are now creating climate solutions

February 5, 2026. Press Release: "American companies are forging ahead with investments in climate-related initiatives, from solar projects to low-emissions jet fuel, even as government incentives to do so are under threat, according to research by a team of Harvard Business School professors. The researchers found that half of U.S. publicly traded firms in climate-relevant industries (49.6%) said they were working on climate solutions of some type in their mandatory annual reports to the Securities and Exchange Commission for 2023. That’s an increase over 2022, when 45% of those companies\ reported climate-related commitments, and a dramatic rise over 2005, when only 20% of public companies reported such activity."
