Since the industrial revolution began, the atmospheric abundance of key greenhouse gases have increased substantially.
Food systems contribute one-third of global anthropogenic greenhouse gas (GHG) emissions, roughly 16.5 GtCO2e year−1from a total 54 GtCO2e year−11,2, with both pre- and post-production phases representing a high and increasing share of total emissions3. The Food and Agriculture Organizati...

Absolute scopes 1 and 2 greenhouse gas emissions did not reduce between 2016 and 2022, but for the majority of industry groups in the dataset, the intensity of scope 1 emissions declined. The utilities, materials, energy, and transportation...
Real-time data indicate that global greenhouse gas emissions continued to increase in 2022. The Big Three Carbon dioxide (CO2)is the most important greenhouse gas, and its atmospheric concentration is measured by parts per million (ppm).Methane (CH4)andnitrous oxide (N2O)are also extraordinarily ...
Greenhouse gas emissions (GHGs) Thedirect greenhouse gas (GHG) emissions from facilities we operate (Scope 1) were 50 million tonnes on a CO2-equivalent basis in 2023, down from 51 million tonnes of CO2equivalent in 2022. The indirect GHG emissions from the energy we purchased (electricity, ...
Stabilizing greenhouse gas (GHG) emissions from croplands as agricultural demand grows is a critical component of climate change mitigation. Emissions intensity metrics--including carbon dioxide equivalent emissions per kilocalorie produced (`production intensity')--can highlight regions, management practices...
