Buying a carbon credit can help an individual or company offset their greenhouse gas emissions’ numbers. The market for these credits is expected to grow exponentially by 2030, as more companies race to meet “net zero” targets. But they come with a host of credibility problems, with many well-documented cases of credits not delivering on promised emissions reductions. In the Brazilian Amazon, there’s another concern: local communities feel pressured by carbon credit companies that are buying up their land. This can sometimes cut people off from land they have hunted and fished in for generations. Sam Schramski and Cicero Pedrosa Neto bring us the story from Para, Brazil.
