A paper published in the journal Science reveals that, although reducing fossil fuel use is essential to meet global climate targets, those goals are out of reach unless the global food system is also transformed. The research shows that what we eat, how much we eat, how much is wasted and how food is produced will need to change dramatically by 2050, if we are to achieve the Paris Climate Agreement’s goal of limiting the increase in global temperature to 1.5°C or 2°C above pre-industrial levels.
If current trends continue, emissions from food systems would surpass the 1.5°C target within 30-45 years, the researchers found, and may exceed the 2°C target within 90 years, even if all other sources of greenhouse gas emissions immediately stopped. If other sources of greenhouse gas emissions reached zero by 2050, the 1.5°C target would be surpassed in 10-20 years and the 2°C target by the end of the century.
Lead author on the paper, Dr Michael Clark, of The Oxford Martin School and Nuffield Department of Population Health says, ‘Discussions on mitigating climate change typically focus on reducing greenhouse gas emissions from burning fossil fuels, for instance, from transportation or energy production. However, our research emphasises the importance of reducing emissions from the global food system.
