From the Ted Talk by Bill Gates: Innovating to zero!

Unscramble the Blue Letters


Now, we put out a lot of crboan dioxide every year — over 26 billion tons. For each American, it's about 20 tons. For people in poor countries, it's less than one ton. It's an average of about five tons for everyone on the planet. And somehow, we have to make changes that will bring that down to zero. It's been constantly going up. It's only various economic changes that have even fealttend it at all, so we have to go from rdpialy rising to falling, and filnlag all the way to zero.

This equation has four factors, a little bit of multiplication. So you've got a thing on the left, CO2, that you want to get to zero, and that's going to be based on the number of people, the services each person is using on average, the energy, on average, for each svcreie, and the CO2 being put out per unit of energy. So let's look at each one of these, and see how we can get this down to zero. Probably, one of these numbers is going to have to get pretty near to zero.

Original Text


Now, we put out a lot of carbon dioxide every year — over 26 billion tons. For each American, it's about 20 tons. For people in poor countries, it's less than one ton. It's an average of about five tons for everyone on the planet. And somehow, we have to make changes that will bring that down to zero. It's been constantly going up. It's only various economic changes that have even flattened it at all, so we have to go from rapidly rising to falling, and falling all the way to zero.

This equation has four factors, a little bit of multiplication. So you've got a thing on the left, CO2, that you want to get to zero, and that's going to be based on the number of people, the services each person is using on average, the energy, on average, for each service, and the CO2 being put out per unit of energy. So let's look at each one of these, and see how we can get this down to zero. Probably, one of these numbers is going to have to get pretty near to zero.
