A new study from Lund University Centre for Sustainability Studies in Sweden has identified the four most efficient things one can do to reduce one’s greenhouse gas emissions. For us who have studied environmental issues they aren’t surprising, but for the general public they might come as a shock since most environmental organizations tend to emphasize other, less efficient actions when calling for a transition to a greener society. The four actions are:
1. Going Vegan
Eating a plant-based diet instead of a meaty one will save you approximately 0.8 tonnes of CO2-equivalents every year. That’s four times more than what you save if you always recycle, and eight times more than changing your lightbulbs to energy efficient ones. In fact, UN studies have shown that the meat and dairy industry account for 18 % of all greenhouse gas emissions, which is why the UN Environmental Program has urged the global population to eat more vegan food.
2. Skipping Air Travel
Air travel is a luxury, being experienced by only 6 % of the world’s population any given year. Every transatlantic trip one avoids saves 1.6 tonnes of CO2-equivalents. A family abstaining from flying to hotter countries every other holiday will do a massive environmental heroic deed. Take the train if you want to go somewhere, or use the Internet to talk with people in other countries. Continue reading How To Save the Climate: No Meat, No Air Travel, No Car and No Babies?
