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.
Transportation accounts for 15% of emissions worldwide. [143] Over a quarter of global transport CO 2 emissions are from road freight, [144] so many countries are further restricting truck CO 2 emissions to help limit climate change. [145] Maritime transport accounts for 3.5% to 4% of all greenhouse gas emissions, primarily carbon dioxide.
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 data include carbon dioxide, methane and nitrous oxide from all sources, including ...
Over the years these cars have gotten bigger and so has their cost to the climate, as carbon dioxide emissions “are almost directly proportional to fuel use” for gas-powered cars.
A European study of nearly 2000 participants showed that an average person cycling 1 trip/day more and driving 1 trip/day less for 200 days a year would decrease mobility-related lifecycle CO 2 emissions by about 0.5 tonnes over a year, representing a substantial share of average per capita CO 2 emissions from transport (which are about 1.5 to ...
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 [n 2] Over the last 150 years, estimated cumulative emissions from land use and land-use change represent approximately one-third of total cumulative anthropogenic CO 2 emissions. [6]
In 2022, a study showed that there are 425 fossil fuel extraction projects (coal, oil and gas) with potential CO2 emissions of more than 1 billion tonnes worldwide. The potential emissions from these projects are twice the 1.5°C carbon budget of the Paris Agreement. According to these researchers, defusing carbon bombs should be a priority for ...
Global map of greenhouse gas (GHG) emissions, including agriculture and land use change, measured in carbon dioxide-equivalents over a 100-year timescale. [2] This is a list of sovereign states and territories by per capita greenhouse gas emissions due to certain forms of human activity, based on the EDGAR database created by European Commission.
