How we can most effectively reduce emissions ? Which emissions can be eliminated with current technologies (and which cannot) ? We need to understand first what the sources of our emissions are.
“Food produces one-quarter of the world’s greenhouse gas emissions
“One-quarter of emissions from food production (3.3 billion tonnes of CO2eq) results from wastage either from supply chain losses or consumers
To lower food’s contribution to emissions, above all we need to waste less – and in a stroke we’d have the problem nearly solved. We will still need a buffet of solutions: changes to diets; improvements in agricultural efficiency; and technologies that make low-carbon food alternatives scalable and affordable.
