Corporate Knights and As You Sow have released the annual update Clean200 list of publicly traded companies that are leading the way with solutions for the transition to a clean energy future.

Since our first report was launched in the summer of 2016 a great deal has changed in the world.

Larry Fink, the CEO of the largest investment firm in the world, wrote in his 2021 letter to CEOs: 

“Given how central the energy transition will be to every company’s growth prospects, we are asking companies to disclose a plan for how their business model will be compatible with a net zero economy – that is, one where global warming is limited to well below 2ºC, consistent with a global aspiration of net zero greenhouse gas emissions by 2050.”
