Money: it's a hit: Give the banker his props: rich societies pollute less and emit less carbon (per unit of energy used) than poorer societies.

We’ve talked before about how rich cities also tend to be clean cities. According to Maslow’s hierarchy of needs, people in subsistence situations tend to scrabble for mere survival, without much regard to any other issues. Only after securing basic life necessities can they focus attention on externalities, such as the environment.

Now comes word that there is something of a linear progression going on:
the richer you are, the greener you are.

As their wealth grows, people consume more energy, but they move to more efficient and cleaner sources — from wood to coal and oil, and then to natural gas and nuclear power, progressively emitting less carbon per unit of energy. This global decarbonization trend has been proceeding at a remarkably steady rate since 1850, according to Jesse Ausubel of Rockefeller University and Paul Waggoner of the Connecticut Agricultural Experiment Station.

The professors argue: “If the energy system is left to its own devices, most of the carbon will be out of it by 2060 or 2070.” All thanks to the free-market system, and the wealth that it brings to us all.

Money…it’s greener than you think!
