The richest 10% of people around the world produce half of global emissions.
That’s according to a report from British charity Oxfam, which also stated the poorest half of the population produce 10% of total emissions worldwide.
It suggests the average footprint of someone in the richest 1% could be 175 times more than of someone in the poorest 10%.
It added between the Copenhagen and Paris climate conferences, the number of billionaires with interests in fossil fuel activities has risen from 54 in 2010 to 88 in 2015.
Their combined fortunes have expanded by around 50% from over $200bn (£132bn) to more than $300bn (£198bn).
The ‘Extreme Carbon Inequality’ report has been published as 150 world leaders, including Prince Charles and UK Prime Minister David Cameron, are in Paris looking for a deal to tackle climate change.
“While COP21 will see a deal negotiated between governments on the basis of the total emissions produced in their territories, the real winners and losers will be the citizens”, the report added.
