BELEM, Brazil — Google has struck its biggest carbon removal deal, agreeing to finance restoration of the Amazon rainforest with Brazilian startup Mombak, as big tech hunts for high-quality credits to offset emissions tied to energy-hungry data centres. The companies said the deal would offset 200,000 metric tons of carbon emissions. …The agreement highlights how big tech is looking for ways to soften the climate impacts of its huge investment in power-intensive data centres for AI, driving demand to offset carbon emissions through Brazil’s nascent reforestation industry. Last year, Alphabet’s Google committed more than US$100 million to an array of different carbon capture technologies, from enhanced rock weathering and biochar to direct air capture and a project making rivers more acidic. But when it came time to double down, it was hard to beat the efficiency of planting trees. [to access the full story a Bloomberg subscription is required]
