The world’s wealthy must radically change their lifestyles to tackle climate change, a report says.

It says the world's wealthiest 1% produce double the combined carbon emissions of the poorest 50%, according to the UN.

The wealthiest 5% alone – the so-called “polluter elite” - contributed 37% of emissions growth between 1990 and 2015.

The authors want to deter SUV drivers and frequent fliers – and persuade the wealthy to insulate their homes well.

The authors urge the UK government to reverse its decision to scrap air passenger duty on UK return flights.

And they want ministers to re-instate the Green Homes Grant scheme they also scrapped recently.
