Several environmental movements on Thursday raised their voices against carbon offset markets, which they consider a useless solution that won’t help to mitigate the effects of climate change, on the fourth day of the ongoing Climate Summit held in Madrid.

Carbon markets "represent a threat to people, politics and the planet", and are a "green washing" strategy, Tom Goldtooth, director of the Indigenous Environmental Network, said.
