The carbon dioxide equivalent (CO 2 e or CO 2 eq or CO 2-e or CO 2-eq) can be calculated from the GWP. For any gas, it is the mass of CO 2 that would warm the earth as much as the mass of that gas. Thus it provides a common scale for measuring the climate effects of different gases.
The following table lists the 1970, 1990, 2000, 2010, 2020, 2021, 2022, and 2023 annual GHG [n 1] emissions estimates (in kilotons of CO 2 equivalent per year) along with a list of calculated emissions per capita (in metric tons of CO 2 equivalent per year).
The following table lists the 1970, 1990, 2000, 2010, 2020, 2021, 2022 and 2023 annual per capita GHG [n 1] emissions estimates (in metric tons of CO 2 equivalent per year). The data include carbon dioxide (CO 2), methane (CH 4) and nitrous oxide (N 2 O) from all sources, including agriculture and land use change. They are measured in carbon ...
The following table lists the annual CO 2 emissions estimates (in kilotons of CO 2 per year) for the year 2023, as well as the change from the year 2000. [4] The data only consider carbon dioxide emissions from the burning of fossil fuels and cement manufacture, but not emissions from land use, land-use change and forestry.
The findings are presented in units of global warming potential per unit of electrical energy generated by that source. The scale uses the global warming potential unit, the carbon dioxide equivalent (CO 2 e), and the unit of electrical energy, the kilowatt hour (kWh). The goal of such assessments is to cover the full life of the source, from ...
Carbon dioxide is often mentioned in the context of its increased influence as a greenhouse gas since the pre-industrial (1750) era. In 2013, the increase in CO 2 was estimated to be responsible for 1.82 W m −2 of the 2.63 W m −2 change in radiative forcing on Earth (about 70%). [48]
This is a list of sovereign states and territories by per capita carbon dioxide emissions [n 1] due to certain forms of human activity, based on the EDGAR database created by European Commission. The following table lists the annual per capita CO 2 emissions estimates (in kilotons of CO 2 per year) for the year 2023, as well as the change from ...
The United States produced 5.2 billion metric tons of carbon dioxide equivalent greenhouse gas (GHG) emissions in 2020, [6] the second largest in the world after greenhouse gas emissions by China and among the countries with the highest greenhouse gas emissions per person.
