Google, along with Amazon and Microsoft, have been accused by Greenpeace of undermining their own climate change pledges by partnering with major oil companies that have looked for new technology to ramp up oil and gas extraction.

In response to the environmentalist group’s report, Google have said they will no longer build custom artificial intelligence tools for speeding up oil and gas extraction, separating themselves from Amazon and Microsoft who have made no such promise. The three tech giants have been working with the likes of Shell, BP, Chevron and ExxonMobil by providing Artificial Intelligence tools to speed up their research.

Google have said they will honour all existing contracts with its customers, but did not share whether this will include the aforementioned oil extractors. However, the change in future deals have been welcomed and applauded by Greenpeace, who are pleased to see that their report had been acknowledged and acted upon.

Greenpeace’s report revealed that Microsoft appeared to be leading the way with the most oil and gas contracts, “offering AI capabilities in all phases of oil production.” Amazon, on the other hand, have been focused more on pipelines, shipping and fuel storage, making use of its sprawling physical infrastructure which has spurred it to so much success in the online marketplace.

Amazon declined to comment on the Greenpeace report, but pointed out that they could not discriminate the energy industry from access to the same level of technology as other industries. Microsoft, on the other hand, published a blog statement on Tuesday which made no direct response to the report, but reiterated its promise to remove all the carbon from the air which it has ever emitted by 2050.

Whilst Google have taken the high road, Amazon and Microsoft continue to help global warming.
