In the 2018 Special Report on Global Warming, the Intergovernmental Panel on Climate Change (IPCC) concluded that to keep global warming under 1.5 degrees Celcius (3.6 Fahrenheit), “global net human-caused emissions of carbon dioxide (CO2) would need to fall by about 45 percent from 2010 levels by 2030, reaching ‘net zero’ around 2050.” As I found in writing “Living the 1.5 Degree Lifestyle,” that meant big changes in how we live, how we eat, and how we move.

By Emma Bryce

There is increasing acceptance that worldwide diets—especially of majority meat-eating countries—need to change to fall in line with global sustainability goals. This is reflected in a rising wave of dietary guidance on the best foods to eat, and which ones to avoid, for the sake of our own health and the planet’s.
