Thomas Wire of the London School of Economics published a study concluding that improved family planning is one of the most effective methods of reducing greenhouse-gas emissions we’ve got. This is something that sustainable-growth advocates have realized for a long time, but the actual numbers are startling: Reducing the number of unwanted pregnancies out there—calculated on the basis of “unmet need,” or women who want contraception but currently don’t have access —is roughly five times as cost-effective as deploying low-carbon technologies like wind, solar, and carbon sequestration.
