Meeting climate targets may require reducing meat, dairy consumption

Greenhouse gas emissions from food production may threaten the United Nations climate target of limiting global warming to two degrees Celsius, according to research. Carbon dioxide emissions from the energy and transportation sectors currently account for the largest share of climate pollution. However, a study from Chalmers now shows that eliminating these emissions would not guarantee staying below the UN limit. Emissions from agriculture threaten to keep increasing as global meat and dairy consumption increases.

Greenhouse gas emissions from food production may threaten the UN climate target of limiting global warming to 2 degrees Celsius, according to research at Chalmers University of Technology, Sweden.On Monday 31 March the Intergovernmental Panel on Climate Change (IPCC) presents their report on the impacts of climate change.Carbon dioxide emissions from the energy and transportation sectors currently account for the largest share of climate pollution. However, a study from Chalmers now shows that eliminating these emissions would not guarantee staying below the UN limit. Emissions from agriculture threaten to keep increasing as global meat and dairy consumption increases. If agricultural emissions are not addressed, nitrous oxide from fields and methane from livestock may double by 2070. This alone would make meeting the climate target essentially impossible.”We have shown that reducing meat and dairy consumption is key to bringing agricultural climate pollution down to safe levels,” says Fredrik Hedenus, one of the study authors. “Broad dietary change can take a long time. We should already be thinking about how we can make our food more climate friendly.”By 2070, there will be many more of us on this planet. Diets high in meat, milk, cheese, and other food associated with high emissions are expected to become more common. Because agricultural emissions are difficult and expensive to reduce via changes in production methods or technology, these growing numbers of people, eating more meat and dairy, entail increasing amounts of climate pollution from the food sector.”These emissions can be reduced with efficiency gains in meat and dairy production, as well as with the aid of new technology,” says co-author Stefan Wirsenius. “But the potential reductions from these measures are fairly limited and will probably not suffice to keep us within the climate limit, if meat and dairy consumption continue to grow.”Beef and lamb account for the largest agricultural emissions, relative to the energy they provide. …
