Ways to Cut Your Carbon Footprint

Our carbon footprint, which drives more global warming, is connected with everything we produce, eat and buy. There are dozens of things we can do to reduce it.

    1    

About one-third of all food gets wasted every year. Producing food that won’t be eaten wastes valuable resources, including energy. It also creates a lot of greenhouse gases. If we don’t buy what we don’t need, we could cut our food carbon footprint by 12 percent.

    2    

People who use traditional vehicles can make up the largest part of carbon footprint. That’s why people should walk more, ride bikes or take public transportation. If you use your car, consider an electric vehicle（EV）. Once they hit the roads, EVs don’t emit planet-warming gases.

    3    

Everything we buy also contributes to our carbon footprint. So a key way to lessen the footprint is to buy fewer new things. Shopping for the second-hand goods cuts much pollution. Next best is to extend the life of your products. Recycle wherever you can.

A. Buy less new stuff
B. Reduce food waste
C. Eat plant-based foods
D. Green your travel
