If cattle were a country, where would they rank on emissions?
If all the cattle in the world joined together to start their own country, they would rank behind only China and the United States in greenhouse gas emissions. But they’d have some competition from the cement industry, which also emits more than India (the country currently ranked 3rd).
How many drivers would have to switch to electric cars to equal the annual emissions saved by replacing one coal power plant with a nuclear plant?
It’s 2.5 million, assuming the electric vehicles get their electricity from the average mix of sources in the U.S. But even if clean energy supplied all the power, over 1.5 million people would still have to switch. To put that in perspective, there are currently only 3 million electric cars on the road in the entire world.
Which sector of the global economy produces as many greenhouse gas emissions as Germany?
Shipping (cargo planes, ships, etc.) currently equals both Germany and Britain in greenhouse gas output – and it’s expected to grow in the future. One study projects global shipping emissions could rise by as much as 250 percent by 2050 and account for 17 percent of all emissions.
How has the share of energy produced by fossil fuels changed in the last 20 years?
Despite our efforts to reduce emissions in recent years, the share of energy produced by fossil fuels is virtually the same today as it was two decades ago. That’s why we urgently need clean, scalable sources of energy.
