CO2 = P x S x E x C

Meaning this: the climate emissions of human civilization are the result of four driving forces:

* Population: the total number of people on the planet (which is still increasing because we are not yet at peak population).

* Services: the things that provide prosperity (and because billions of people are still rising out of poverty and because no global system will work unless it's fair, we can expect a massively increased demand for the services that provide prosperity).

* Energy: the amount of energy it takes to produce and provide the goods and services that our peaking population uses as it grows more prosperous (what some might call the energy intensity of goods and services). Gates believes it's likely cutting two-thirds of our energy waste is about as good as we can do.

* Carbon: the amount of climate emissions generated in order to produce the energy it takes to fuel prosperity.
