Greenhouse gas emissions per 1000 calories

 Here, I talked about greenhouse gas emissions per kilogram.  This chart shows greenhouse gas emissions per 1000 calories.  The chart is from Our World in Data.

The conclusion is the same:  even without becoming fully vegetarian, by avoiding beef, fish, lamb and mutton, you could significantly cut your emissions from food, which makes up ~30% of total greenhouse gas emissions.  Becoming fully vegetarian would cut your emissions even more.  And becoming vegan would be even better.  Don't say tofu is just as bad as beef---in the chart from my previous post, tofu produces 3.2 kilograms of CO2-equivalent per kilogram vs beef's 99 kg CO2-equivalent.

Purity is not essential.  Going from eating meat three times a day to once a day reduces your emissions and animal suffering and forest clearing.  Eating meat once a week instead of once a day, ditto.  You get the picture.

Not eating meat is something we can do personally, individually.  So is buying our electricity from a green supplier* and driving a hybrid or EV.  Together, taking these steps could reduce your emissions by ~70%.  

* Many so-called "green" electricity providers use carbon offsets to "reduce" the carbon emissions produced by burning fossil fuels to generate their electricity.  Most carbon offsets have turned out not to reduce emissions, i.e., to be fake, and many of them are out-and-out scams.  Choose a provider that generates all its electricity from its own wind, solar, nuclear, hydro or wave/tidal electricity, or from contracts it has with wind and solar farms.
