Put to the test
Can you beat my score on this climate change quiz?
I asked my team to put together this short quiz, and then I took it. Now it’s your turn.

What causes climate change?

Aside from some notable skeptics, everyone knows that it’s caused by greenhouse gases produced by human activity. It’s common knowledge today that emissions get trapped in our atmosphere and increase the planet’s temperature. But where do these gases come from?

I think most people would say generating electricity. They’re not wrong: electricity produces 25 percent of emissions, the most of any sector. But that means 75 percent come from sources other than generating electricity. If we’re going to really solve climate change, we need to look at all the major drivers of greenhouse gas emissions.

I’ve learned a lot about where emissions come from since the launch of the Breakthrough Energy Coalition two years ago—and a lot of what I’ve learned has surprised me. I asked my team to put together this short quiz to test my knowledge, and then I took it (I knew three answers for sure but had to guess on two). Now it’s your turn. Can you beat my score?
