"Facing a reckoning over their contribution to the climate emergency, companies are coming out with a record number of pledges"

"As countries are under pressure to up their climate ambitions in the run-up to Cop26, the vital UN climate talks in November, the private sector is also being increasingly pushed by investors, employees, activists and consumers to take meaningful action."

The Guardian’s new series, Green light, will examine businesses’ accountability for the climate crisis and interrogate the promises, innovations and solutions they are offering to tackle it. It will explore what role companies must play in the world’s last-chance push to transform the economy and keep warming within the 1.5C ambition laid out in the Paris climate agreement. The good news is that companies have been embracing climate pledges in unprecedented numbers. Across sectors – from technology and food to fossil fuels and aviation – they are making commitments to a lower carbon world with promises to become “net zero”, “carbon negative”, “regenerative”, “deforestation free”.
