'Put a big fat price on carbon': OECD chief bows out with climate rally cry

Exclusive: Angel Gurria says action on environmental crises must be defining focus of wealthy countries after Covid

• Finance ministers have to be green, says head of OECD

The environment, climate change and the protection of nature must be the defining tasks of rich and major developing countries now and in the years to come, the outgoing head of the Organisation for Economic Co-operation and Development has said, and the institutions that advise governments must take responsibility for keeping them focused on those tasks.

Angel Gurria said the coronavirus crisis must be dealt with as a matter of urgency, but that the biggest task after that would be tackling the world's environmental emergencies.
