In recent months, the group of Big Tech companies have ramped up announcements asserting their commitment to tackling climate change.

Microsoft, Apple, Amazon and Samsung are some of the world’s largest tech companies, and organisations with some of the largest environmental footprints.

Time and again these big firms have come up with statements talking about their commitment and taking climate change pledges.

Following is a comprehensive list of climate change commitments or actions, taken by some of the most influential tech companies in shaping a greener backbone of the future global economy.


Amazon hit 127 renewable energy projects and declared itself the biggest corporate buyer of renewable energy in 2020. it also plans to power its operations with 100% renewable energy by 2025.

In 2019, Amazon and Global Optimism co-founded The Climate Pledge, a commitment to net-zero carbon by 2040. Since then, a growing list of major companies have joined The Climate Pledge.

Google pledged to run all of its worldwide data centers and corporate campuses on 100% carbon-free power by 2030. The carbon commitment followed the company’s Earth Day investment in its carbon-intelligent computing platform, which will optimize scheduling of compute tasks to run when low-carbon power sources, like wind and solar, are most abundant.


IBM announced ts agenda to hit “net zero” greenhouse gas emissions by 2030. “Net zero” means that the greenhouse gases emitted are equivalent to those that are removed.

To achieve “net zero", IBM will reduce greenhouse gas emissions by 65% by 2025 when compared to its emissions in 2010, use 75% renewable energy-powered electricity by 2025 and 90% renewable energy electricity by 2030, and use carbon capture or other technologies to remove greenhouse gases equal to its “residual emissions.

IBM has also joined The Climate Pledge, a public commitment to reduce carbon emissions launched by Amazon and Jeff Bezos in 2019.

The company’s much-publicised ‘iPhone dismantling robot’ spearheads a recycling initiative that has seen Apple dramatically reduce its need for mining new rare earth minerals for use in its products; it expects to have cut its aluminium-bearing bauxite production by 900,000 tonnes , and 29,000 tonnes of tin ore .

Samsung is aiming to reform many of its operations and processes to improve efficiency, and reduce the volume of waste, such as carbon dioxide, produced at its operations. The company aims to cut its emissions by roughly half over a two year period, from 3.59 tons of carbon dioxide per million Korean won in 2018 to just 1.55 by the end of 2020. Similarly, it is targeting a year-on-year reduction in carbon dioxide production of seven million tons of carbon dioxide in 2020, which would see the company’s total carbon dioxide reduction reach 250 million tons since 2008.
