Here’s a fun calculator to play with. You choose a food item and indicate how often you eat it. The calculator indicates greenhouses gases associated with that dietary item, but it also gives you a graph showing how that item compares to other similar foods. So rather than pushing you to go all-vegan, it helps you find more climate friendly alternatives for your existing diet. Note the results are global figures; they don’t take into account buying local and in season.
I chose apples, 3-5 times a week, because my husband and I often share one as dessert (along with some chocolate, of course!). Fortunately, the calculator’s results gave me a pat on the back.
