Shell boss says mass reforestation needed to limit temperature rises to 1.5C

Ben van Beurden says 'another Brazil in terms of rainforest' will help achieve UN target

The boss of Shell has said a huge tree-planting project the size of the Amazon rainforest would be needed to meet a tougher global warming target, as he argued more renewable energy alone would not be enough.

Ben van Beurden said it would be a major challenge to limit temperature rises to 1.5C (equivalent to a rise of 2.7F), which a landmark report from the UN's climate science panel has said will be necessary to avoid dangerous warming.
