[Greenbuilding] Net Zero Carbon Emissions Economy

[Norbert Senf]

A number of years ago I saw a statistic from the CIA that the total world
petroleum production divided by the world population is equal to something
like 2 litres per person day. Since most of us G-20 inhabitants use much
more than 2 litres per day, a lot of people are obviously using less.
