Billionaires emit a million times more greenhouse gases than the average person: Oxfam- The investments of 125 of the world's richest billionaires cause 393 million metric tonnes of carbon dioxide emissions every year, according to a report by Oxfam.That's the equivalent CO2 output to the whole of France and makes the average billionaire's annual emissions a million times higher than a person in the poorest 90% of the world's population, the global poverty charity says.The billionaires included in the study have a collective $2.4 trillion stake in 183 companies, which averages out at 3 million metric tonnes of carbon dioxide emitted per billionaire, per year.People outside the world's wealthiest 10% emit an average of 2.76 metric tonnes of carbon dioxide annually.Danny Sriskandarajah, chief executive of Oxfam GB, called for world leaders at the COP27 climate summit to "expose and change the role that big corporates and their rich investors are playing in profiting from the pollution that is driving the climate crisis.""
