Contraception would be the cheapest and most effective way to reduce carbon emissions worldwide between 2010 and 2050, according to a study by the London School of Economics.
The report, "Fewer Emitters, Lower Emissions, Less Cost," (PDF) determined that if contraception was made widely available between 2010 and 2050 to women and men around the world who wished to use it, the reduction in unwanted births could result in saving 34 gigatonnes (one billion tonnes) of carbon emissions. That's roughly 60 years worth of U.K. emissions or 6 years worth of U.S. emissions.
The cost for supplying, and distributing contraception over those 40 years would cost an estimated $220 billion, or $7 for each tonne of carbon emissions avoided. It's cheaper than the next most efficient low-carbon technology, wind power, which would cost $24 per tonne or $1 trillion to prevent the same amount (one billion ...
