Extensive land uses to meet dietary preferences incur a ‘carbon opportunity cost’ given the potential for carbon sequestration through ecosystem restoration. Here we map the magnitude of this opportunity, finding that shifts in global food production to plant-based diets by 2050 could lead to sequestration of 332–547 GtCO 2 , equivalent to 99–163% of the CO 2 emissions budget consistent with a 66% chance of limiting warming to 1.5 °C. Shifting global food production to plant-based diets by 2050… 

Carbon opportunity costs of biofuels in Germany—An extended perspective on the greenhouse gas balance including foregone carbon storage

Biomass-based fuels are frequently considered a Greenhouse Gas (GHG) emission reduction option. However, the aspect of foregone emission reduction which is related to alternative options such as

2040) and ultimate (2050) milestones: Cropland use stopped and all Cropland converted to Grassland by 2030; Water tables raised to the soil surface on 15 % / 60 % / 100 % of all Grassland, on 50 % /

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

Dietary changes could compensate for potential yield reductions upon global river flow protection

Non-technical summary Globally, freshwater systems are degrading due to excessive water withdrawals. We estimate that if rivers’ environmental flow requirements were protected, the associated

Rapid global phaseout of animal agriculture has the potential to stabilize greenhouse gas levels for 30 years and offset 68 percent of CO2 emissions

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.

Extension services can promote pasture restoration: Evidence from Brazil’s low carbon agriculture plan

Significance Livestock supply chains account for 14.5% of global greenhouse gases (GHG) emissions. There is a consensus that approaches that improve cattle productivity while enhancing carbon

How necessary and feasible are reductions of methane emissions from livestock to support stringent temperature goals?

It is concluded that bringing livestock into mainstream mitigation policies, while recognizing their unique social, cultural and economic roles, would make an important contribution towards reaching the temperature goal of the Paris Agreement and is vital for a limit of 1.5°C.

Greenhouse gas emissions from food systems: building the evidence base

New estimates of greenhouse gas (GHG) emissions from the food system were developed at the country level, for the period 1990–2018, integrating data from crop and livestock production, on-farm energy

Written Testimony of Earthjustice on Voluntary Carbon Markets in Agriculture and Forestry Before The House Committee on Agriculture

Thank you for the opportunity to testify on the role of voluntary carbon markets in the agriculture and forestry sectors, and how to take advantage of these sectors’ tremendous prospects to both

Silvopastoral systems and remnant forests enhance carbon storage in livestock-dominated landscapes in Mexico

A large area of the terrestrial land surface is used for livestock grazing. Trees on grazing lands provide and can enhance multiple ecosystem services such as provisioning, cultural and regulating,



Trading carbon for food: Global comparison of carbon stocks vs. crop yields on agricultural land

By factoring crop yield into the analysis, this work specifies the tradeoff between carbon stocks and crops for all areas where crops are currently grown and thereby, substantially enhance the spatial resolution relative to previous regional estimates.

Climate benefits of changing diet

Climate change mitigation policies tend to focus on the energy sector, while the livestock sector receives surprisingly little attention, despite the fact that it accounts for 18% of the greenhouse

The opportunity cost of animal based diets exceeds all food losses

It is shown that plant-based replacements for each of the major animal categories in the United States (beef, pork, dairy, poultry, and eggs) can produce twofold to 20-fold more nutritionally similar food per unit cropland.

Redefining agricultural yields: from tonnes to people nourished per hectare

Worldwide demand for crops is increasing rapidly due to global population growth, increased biofuel production, and changing dietary preferences. Meeting these growing demands will be a substantial

Defining a land boundary for sustainable livestock consumption

It is demonstrated that livestock raised under the circular economy concept could provide a significant, nonnegligible part of the authors' daily protein needs and that including some ASF in the human diet could free up about one quarter of global arable land.

Unexpectedly large impact of forest management and grazing on global vegetation biomass

It is shown, using state-of-the-art datasets, that vegetation currently stores around 450 petagrams of carbon, in the hypothetical absence of land use, which implies that trade-offs exist between conserving carbon stocks on managed land and raising the contribution of biomass to raw material and energy supply for the mitigation of climate change.

Feed conversion efficiency in aquaculture: do we measure it correctly?

Comparing all terrestrial and aquatic animals in the study, chickens are most efficient using these measures, followed by Atlantic salmon, and protein and calorie retention for aquaculture production is comparable to livestock production.

Negative effects of cattle on soil carbon and nutrient pools reversed by megaherbivores

This field study finds that wild megaherbivores, such as elephants, increased soil carbon and nitrogen, and hence soil fertility, normally lost when only cattle are present.

Greenhouse gas mitigation potentials in the livestock sector

The livestock sector supports about 1.3 billion producers and retailers, and contributes 40-50% of agricultural GDP. We estimated that between 1995 and 2005, the livestock sector was responsible for
