As of 2021 the remaining carbon budget for a 50-50 chance of staying below 1.5 degrees of warming is 460 bn tonnes of CO 2 or 11 + 1 ⁄ 2 years at 2020 emission rates. [14] Global average greenhouse gas per person per year in the late 2010s was about 7 tonnes [15] – including 0.7 tonnes CO 2 eq food, 1.1 tonnes from the home, and 0.8 tonnes from transport. [16]
