This January was the warmest globally on record, according to the World Meteorological Record. As temperatures and sea levels rise across the globe, extreme weather phenomena may happen more frequently and precipitation patterns may become more unpredictable, causing either severe droughts or increased flooding.

Despite the challenges ahead, businesses are stepping up to reduce their carbon footprint. And that’s why Newsweek and Plant-A Insights Group are proud to recognize Newsweek's World’s Greenest Companies 2025, featuring companies like ASR Nederland, Dayforce, Paragon Banking Group, Sopra Steria and Vonovia who are prioritizing environmental sustainability.

Newsweek has partnered with Plant-A Insights and GIST Impact to spotlight businesses worldwide who are determined to mitigate their climate impact. The ranking is based on research of publicly available data provided by GIST Impact as available through March 1, 2025.

We hope this ranking helps environmentally conscious consumers identify which companies go above and beyond in their efforts to minimize their ecological impact, seeking to foster a sustainable tomorrow.
