To take just one example, ongoing work is focusing on the environmental footprint of global food waste. Early results suggest that the carbon footprint of food produced but not consumed is 3.3 billion tonnes C02 eq/a, representing around 9% of total global GHG emissions.14 Were such emissions generated by a country, that country would be the world’s third-largest GHG emitter, behind only the US and China. Extending that to waste and resource management in a broader sense would significantly increase the potential, to 15 to 20% or perhaps even more, if waste prevention was also included. As shown in Figure 1, most of the sites are in Africa, Asia and Latin America/Caribbean, with two in Europe.
