A couple of changes could slash the carbon footprints of school lunches in the US Shutterstock/Dragan Mujan
School districts in the US could almost halve the carbon emissions of school lunches by adopting two changes: serving beef only once a month and replacing the highest carbon-emitting meal each week with a vegan option. The finding suggests that tweaking school lunches could be an effective way of reducing the impact diet has on climate – a critical task given food production constitutes about 37 per cent of global greenhouse gas emissions.
