Greta Thunberg tells world leaders to end fossil fuel ‘madness’

Failure to end investment 'would be a betrayal against life itself', say climate activists

• Greta Thunberg and others: 'At Davos, we will tell the tycoons to dismantle the fossil fuel economy'

Greta Thunberg and fellow youth climate campaigners are demanding that global leaders immediately end the "madness" of huge ongoing investments in fossil fuel exploration and enormous subsidies for coal, oil and gas use.

The 21 young activists are also calling on the political and business leaders who will be attending the World Economic Forum in Davos to ensure investment funds dump their holdings in fossil fuel companies.
