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...
According to the IPCC, the anthropogenic greenhouse gas (GHG) emissions contributing most evidently to Global Warming in terms of relative radiative forcing are CO2 , CH4 , halocarbons and N2O. CO2 emissions originate mainly from combustion of fossil fuels, and are quite well-known. However, ...

The world's population is now over 50% urban, and cities make an important contribution to national greenhouse gas (GHG) emissions. Many cities are developing strategies to reduce their emissions. Here we ask how and why emissions differ between cities. Our study of ten global cities shows how...
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...
Throughout the spring, greenhouse gas emissions plummeted around the world as factories, air traffic, and other forms of transportation ground to a halt due to the pandemic crisis. As the world starts opening up once more, scientists are watching a rebound in air pollution. ...
Global high-resolution crop-specific estimates of greenhouse gas emissions intensity (in 2000) reveal that certain cropping practices contribute disproportionately to emissions, making them suitable targets for climate mitigation policies. Stabilizing gr
greenhouse gas emissions, there will be new opportunities for developing and using bioenergy technologies that can contribute to a wider range of economic, ... J Woods - 《Vision Briefs》 被引量: 37发表: 2006年 加载更多研究点推荐 greenhouse gas emissions ...
As world leaders and corporate representatives have returned from COP27 in Sharm el-Sheikh, a major challenge remains to bend the curve of global greenhouse-gas (GHG) emissions and mitigate the worst outcomes of climate change. While the global media’s focus will quickly shift to other,...
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...
