An alliance of 107 countries, including Brazil, the EU and the US, have joined the pact known as the Global Methane Pledge, committing to a collective goal of reducing global methane emissions by at least 30% from 2020 levels by 2030. [71] [72] The European Union adopted methane regulations in 2024.
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 ...
Scientists had long projected wetland methane emissions would rise as the climate warmed, but from 2020 to 2022, air samples showed the highest methane concentrations in the atmosphere since ...
The world saw a record jump in levels of methane in the atmosphere last year as the main heat-trapping greenhouse gases reached new highs, UN experts said. ... from 2020 to 2021 was larger than ...
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]
ExxonMobil (XOM) undertakes several measures to curb greenhouse gas and expects to lower emissions by 2020.
In 2020, 27% of the GHG emissions of the United States were from transportation, 25% from electricity, 24% from industry, 13% from commercial and residential buildings and 11% from agriculture. [13] U.S. energy-related CO2 emissions decreased by 3% in 2023, amounting to a reduction of approximately 134 million metric tons (MMmt).
The concentration of atmospheric methane is increasing due to methane emissions, and is causing climate change. [3] [4] Methane is one of the most potent greenhouse gases. [5]: 82 Methane's radiative forcing (RF) of climate is direct, [6]: 2 and it is the second largest contributor to human-caused climate forcing in the historical period.
