food

Your shopping basket is spewing greenhouse gases. But don't worry, you can easily cut out the culprits

• eating less red meat and dairy can be a more effective way to lower an average U.S. household's food-related climate footprint than buying local food
• a steak is equivalent to driving 30 kilometers
• switching to vegetables one day per week cuts the equivalent of driving 1160 miles per year (these are data from the US)
