One thing is clear: The world can only meet even the less ambitious climate targets if the consumption of fossil fuels is cut-off or massively reduced immediately. At least this share should therefore have been included in coal and oil company figures as early as 2010 instead, it now forms a significant part of the carbon bubble. At that time, however, the remaining CO 2 budget was only 565 gigatonnes – burning this potential would so already have meant an excess of 180 gigatonnes. ![]() What these figures mean for the fossil energy industry becomes clear in a calculation by the Carbon Tracker Initiative: In 2010, the 100 largest coal-producing companies, together with the 100 largest oil and gas-producing companies, had bunkered an emission potential of 745 gigatonnes of CO 2 in deposits all over the world. As a result, there will be only 236 gigatonnes of CO 2 left from 2020 on - a quantity that will probably be depleted before the end of the decade. Trouble is: From 2000 to 2010 we have already emitted 321 gigatonnes of CO 2 from 2010 to 2020, assuming an annual growth rate of one percent from 2018, we can expect additional 330 gigatonnes. If we exceed this amount, the two-degree limit is overstepped. For some decades now, world climate research has agreed on a "budget" of 886 gigatonnes of CO 2 for the period 2000 to 2050.
