  2. List of countries by carbon dioxide emissions - Wikipedia

    en.wikipedia.org/wiki/List_of_countries_by...

    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.

  3. Greenhouse gas emissions - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_gas_emissions

    Emissions of carbon dioxide, methane and nitrous oxide in 2023 were all higher than ever before. [6] Electricity generation, heat and transport are major emitters; overall energy is responsible for around 73% of emissions. [7] Deforestation and other changes in land use also emit carbon dioxide and methane.

    World map of emission intensity (kg of CO 2 per Intl$), 2018. The following list of countries by carbon intensity of GDP sorts countries by their emission intensity.Carbon intensity or emission intensity of GDP is a measure that evaluates the amount of carbon dioxide (CO 2) emissions produced per unit of GDP.

    [n 2] [6] In 2023, global GHG emissions reached 53.0 Gt CO 2 eq (without Land Use, land Use Change and Forestry). The 2023 data represent the highest level recorded and experienced an increase of 1.9% or 994 Mt CO 2 eq compared to the levels in 2022. The majority of GHG emissions consisted of fossil CO 2 accounting for 73.7% of total emissions. [7]

  7. Transient climate response to cumulative carbon emissions

    en.wikipedia.org/wiki/Transient_climate_response...

    [7] [8] [2] This means that for specific amount of cumulative CO 2 emissions, a known global temperature change (within a range of uncertainty) can be expected, which indicates that holding global temperature change to below specific thresholds is a problem of limiting cumulative CO 2 emissions, leading to the idea of a carbon budget.

  8. Life-cycle greenhouse gas emissions of energy sources

    en.wikipedia.org/wiki/Life-cycle_greenhouse_gas...

    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. ...

    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 ...
