The average American currently eats over a pound of beef each week (roughly equal to 4 burgers), and beef is between five and ten times worse for the climate than chicken.
The U.S. produces one-fifth of the world's beef, which is responsible for nearly 10% of global greenhouse gas emissions.
Thus, reducing beef consumption to 1 burger per week (the maximum amount consistent with a sustainable global emissions level) would eliminate 1.5% of global greenhouse gas emissions.
Takeaway: regardless, both countries must increase efforts to reduce carbon pollution.
Recent data show that China is the biggest current emitter of greenhouse gases (GHGs), producing 22% of the world's current annual emissions.
The U.S. is the biggest historical emitter (27% of the world's cumulative GHG emissions since 1850), followed by the European Union (25%) and China (11%).
By 2030, India's annual emissions could equal or even surpass those of the U.S, if they don't pass additional policies to reduce emissions.
