Agriculture and land use are major sources of greenhouse gas (GHG) emissions but previous estimates were either highly aggregate or provided spatial details for subsectors obtained via different methodologies. Using a model–data integration approach that ensures full consistency between subsectors, we provide spatially explicit estimates of production- and consumption-based GHG emissions worldwide from plant- and animal-based human food in circa 2010. Global GHG emissions from the production of… 
Impact of Dietary Meat and Animal Products on GHG Footprints: The UK and the US
Direct and indirect greenhouse gas (GHG) emissions from the ~30+ billion animals consumed as food each year contribute ~14–16% of the global total. The aim of this research is to determine the
Rapid global phaseout of animal agriculture has the potential to stabilize greenhouse gas levels for 30 years and offset 68 percent of CO2 emissions
TLDR
It is shown that the global warming impact of eliminating greenhouse gas emissions from livestock and allowing native ecosystems to regrow on the land currently used to house and feed livestock, would be equivalent to a 68% reduction in carbon dioxide emissions.
Rapid global phaseout of animal agriculture has the potential to stabilize greenhouse gas levels for 30 years and offset 68 percent of CO2 emissions this century
Animal agriculture contributes significantly to global warming through ongoing emissions of the potent greenhouse gases methane and nitrous oxide, and displacement of biomass carbon on the land used
The carbon footprint of cold chain food flows in the United States
The food system is an important contributor to carbon dioxide (CO2) emissions. The refrigerated food supply chain is an energy-intensive, nutritious and high-value part of the food system, making it
Plant to animal protein ratio in the diet: nutrient adequacy, long-term health and environmental pressure
TLDR
There is no single optimal %PP when considering only nutrition and health, but high %PP diets are more sustainable, and for %PP>80%, nutrient fortification/supplementation and/or new foods are required.
Turning Food Protein Waste into Sustainable Technologies.
For each kilogram of food protein wasted, between 15 and 750 kg of CO2 end up in the atmosphere. With this alarming carbon footprint, food protein waste not only contributes to climate change but
Sustainable intensification in the Brazilian cattle industry: the role for reduced slaughter age
The cattle industry in the Brazilian Amazon causes vast deforestation while producing at only one-third of the sustainable capacity. Slaughtering cattle at a younger age directly increases production
Comparing national greenhouse gas budgets reported in UNFCCC inventories against atmospheric inversions
Abstract. In support of the Global Stocktake of the Paris Agreement on Climate change, this study presents a comprehensive framework to process the results of atmospheric inversions in order to make

Biomass use, production, feed efficiencies, and greenhouse gas emissions from global livestock systems
TLDR
This report presents a unique, biologically consistent, spatially disaggregated global livestock dataset containing information on biomass use, production, feed efficiency, excretion, and greenhouse gas emissions for 28 regions, 4 animal species, and 3 livestock products.
Greenhouse gas emissions intensity of global croplands
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
Assessing the efficiency of changes in land use for mitigating climate change
TLDR
A carbon benefits index is proposed that measures how changes in the output types, output quantities and production processes of a hectare of land contribute to the global capacity to store carbon and to reduce total greenhouse gas emissions.
Biogenic carbon fluxes from global agricultural production and consumption
Quantification of biogenic carbon fluxes from agricultural lands is needed to generate comprehensive bottom‐up estimates of net carbon exchange for global and regional carbon monitoring. We estimated

We present an assessment of biofuel use and agricultural field burning in the developing world. We used information from government statistics, energy assessments from the World Bank, and many
Farming the planet: 2. Geographic distribution of crop areas, yields, physiological types, and net primary production in the year 2000
Croplands cover ∼15 million km2 of the planet and provide the bulk of the food and fiber essential to human well‐being. Most global land cover data sets from satellites group croplands into just a
Reducing food’s environmental impacts through producers and consumers
TLDR
Cumulatively, the findings support an approach where producers monitor their own impacts, flexibly meet environmental targets by choosing from multiple practices, and communicate their impacts to consumers.
Increased nitrogen enrichment and shifted patterns in the world's grassland: 1860–2016
Abstract. Production and application to soils of manure excreta from livestock farming significantly perturb the global nutrient balance and result in significant greenhouse gas emissions that warm
CO2 emissions from land‐use change affected more by nitrogen cycle, than by the choice of land‐cover data
TLDR
The results indicate that exclusion of N dynamics leads to an underestimation of LULUC emissions by around 70% in the non tropics, 10% in and globally in the 1990s, and the importance of accounting for different processes, in particular the N cycle is indicated.
