IBM and Iceland Foods are among 20 new signatories to the Climate Pledge, which requires members to work towards net-zero carbon emissions by 2040.
Other new businesses to join include Johnson Controls, Ecotricity's owner Green Britain Group and ride-hailing app Free Now.
In total, 53 companies across 18 industries and 12 countries have signed up to the Climate Pledge, which was launched by Amazon and Global Optimism two years ago.
Collectively, this has “the potential to significantly reduce corporate carbon emissions”, Amazon and Global Optimism say.
Each organisation is at a different stage in its journey to net-zero carbon emissions and some are looking to achieve net zero sooner than 2040.
IBM, which has sustained a goal to reduce CO2 emissions since 2000, aims to have net-zero carbon emissions by 2030.
Free Now, which serves more than 50 million passengers in more than 150 cities, is committed to shifting 50% of its vehicles across Europe to zero emissions by 2025 and making all passenger trips emission free by 2030.
Marc Berg, Free Now CEO, said: “It is our ambition and our commitment to the cities where we operate to do our bit to reduce emissions and make it easier for people to make environmentall-friendly choices.
“We are proud of the progress we’ve already made toward our commitments, but we can go much further. We are thrilled to be joining other sustainability minded companies with The Climate Pledge.”
Amazon itself wants to “build the most sustainable transportation fleet in the world”, according to founder and CEO Jeff Bezos.
Last year it added 1,800 electric Mercedes-Benz vans to its European fleet and partnered with Rivianto launch a new custom van, with plans for 10,000 on the road by 2022 and 100,000 by 2030.
