Jamie Livingstone, the head of Oxfam Scotland, hit out as new research showed that by the end of this decade the carbon footprints of the richest 1 per cent of people on earth are set to be 30 times greater than what is compatible with keeping global warming below 1.5 degrees.
The authors of a new report have called for governments to bring in measures to “constrain luxury carbon consumption like mega yachts, private jets and space travel”.
It comes after earlier this year Amazon founder Jeff Bezos made a short trip into space, Sir Richard Branson journeyed to the edge of space in his Virgin Galactic rocket plane, while Elon Musk’s private spaceflight company SpaceX is developing a vehicle to take humans to Mars.
However scientists say that to achieve the goal agreed at the Paris climate summit in 2015, every person on earth would need to limit their CO2 emissions to just 2.3 tonnes by 2030 – roughly half the average carbon footprint today.
A new study for Oxfam, based on research by the Institute for European Environmental Policy (IEEP) and the Stockholm Environment Institute (SEI), found that the richest 1 per cent of people are set to exceed this limit by 30 times.
This group of people – smaller than the population of Germany – are expected to account for 16 per cent of total emissions by 2030, up from 13 per cent in 1990 and 15 per cent of emissions in 2015.
Meanwhile the total emissions produced by the richest 10 per cent could be sufficient on their own to exceed the aligned level for 1.5 degrees in 2030, regardless of what the other 90 per cent of people do.
Mr Livingstone said: “The luxury lifestyles and continued plundering of the planet by the world’s richest people are placing us all in ever graver peril.
“The emissions from a single billionaire space flight would exceed the lifetime emissions of someone in the poorest billion people on earth.
“No one is immune from the impact of the climate emergency, but it’s the world’s poorest who are paying the heaviest price despite contributing least emissions as they battle floods, famines and cyclones.”
With the new study released during the COP26 climate summit in Glasgow, as countries from across the world discuss how they can best curb emissions, Mr Livingstone said the massive gathering was a “moment of truth in the fight against climate change”.
He demanded: “Global leaders must agree ways to curb excessive emissions and limit global heating and they must do it here and now in Glasgow. Delay costs lives.”
Oxfam is calling on nations across the globe to commit to making deeper emissions cuts by 2030, but also ensuring that the richest people make the most radical cuts.
The charity argues that the richest citizens could dramatically speed up action against global warming by not only leading greener lifestyles, but also using their political influence and investments to drive a more low carbon economy.
