Amazon and other companies have agreed to buy carbon offset credits that will support the conservation of its namesake rainforest in the Brazilian state of Para, in a deal valued at around $180 million.

Amazon, drug and chemical maker Bayer, consultancies BCG and Capgemini, clothing retailer H&M and Walmart Foundation will collectively buy 5 million credits at $15 per credit. That is far above the average last week of $4.49 for carbon credits linked to nature, according to data provider Allied Offsets.

Seattle-area tech giant Amazon is part of a $180 million deal with at least five other companies to buy carbon removal credits that will protect a portion of the Brazilian rainforest, according to Reuters.

E-commerce giant Amazon ($AMZN) is buying carbon offset credits that will be applied to the rainforest in South America’s Amazon jungle. According
