The total carbon footprint of the richest 1% will grow while that of the poorest 50% stays small, a study says.

Emissions of the wealthiest are on track to be 30 times higher than what’s needed to stop the planet from warming above 1.5C, according to the study.

The poorest 50%, however, will be most severely impacted by climate change.

The research, carried out by two European environmental agencies, comes as world leaders meet at the COP26 climate conference in Glasgow.

“A tiny elite appears to have a free pass to pollute,” says Naftoke Dabi at Oxfam, which commissioned the study from the Stockholm Environment Institute and the Institute for European Environmental Policy.

“Their over-sized emissions are fuelling extreme weather around the world and jeopardising the international goal of limiting global heating.”

Climate scientists warn that there is a finite amount of greenhouse gases that we can continue to release into the atmosphere before the planet warms to more than 1.5C from pre-industrial levels. By 2030, they say, we need to only emit as much carbon as the planet can absorb.

If this amount were split evenly and every adult on the planet had a share, by 2030 we could each emit 2.3 tonnes of carbon every year.

The super-rich – many of whom have multiple homes, private jets and superyachts – emit a lot more than others. A recent study that tracked the air travel of celebrities via their social media accounts found some emitted over a thousand tonnes a year.

But the global 1% are not just billionaires, or even millionaires – it includes anyone earning over $172,000.
