2. What is net-zero? | Kristen Bell + Giant Ant

What is netzero? We release55 gigatonsof greenhouse gases intothe air every year. To stop global warming, we have to get our greenhouse gas emissionsdown to zero.

But for every country to immediately shut down all greenhouse gas-releasingactivities would be an enormouschallenge, especially since some countries have built up an economichead start with no restrictions. So instead, we can use an approach called net zero.

Net zeromeans that for every molecule of greenhouse gas we put into the air, we also take one out, making our net emissions zero. Net zero requires us to make big changes today, use less, more efficiently, and even bigger technological changes for the future, like replacing all greenhouse gas-emitting activities with clean ones. We'll also have to capturegreenhouse gases fromthe air and store them permanently. And yet, net zero is our best chance for a sustainablefuture.
