The carbon footprint explained Comparison of the carbon footprint of protein-rich foods [1]. A formal definition of carbon footprint is as follows: "A measure of the total amount of carbon dioxide (CO 2) and methane (CH 4) emissions of a defined population, system or activity, considering all relevant sources, sinks and storage within the spatial and temporal boundary of the population, system ...
The current CO 2-equivalent emission rates averaging 6.6 tonnes per person per year, [8] are well over twice the estimated rate 2.3 tons [9] [10] required to stay within the 2030 Paris Agreement increase of 1.5 °C (2.7 °F) over pre-industrial levels. [11]

An assessment of around 180 ocean technologies found that the GWP of ocean technologies varies between 15 and 105 g/kWh of CO 2 eq, with an average of 53 g/kWh CO 2 eq. [10] In a tentative preliminary study, published in 2020, the environmental impact of subsea tidal kite technologies the GWP varied between 15 and 37, with a median value of 23. ...
Total CO 2 emissions per capita decreased from 8.7 t in 1990 to 7.8 t in 2007, that is to say a decrease by 10%. Almost 40% of the reduction in CO 2 intensity is due to increased use of energy carriers with lower emission factors. Total CO 2 emissions per unit of GDP, the “CO 2 intensity”, decreased more rapidly than energy intensity: by 2. ...
