Study suggests family planning is one of the lowest-cost ways to reduce CO2.
People may be the problem, but what’s the solution? Although energy use is driven by demographic trends, we don’t seem to have many tools readily at hand for addressing population as a root cause of climate change. But a new study suggests that a simple investment in family planning services might save an enormous amount of carbon emissions at very low cost.
Specifically, the report claims that the world can spare 34 gigatons of CO2 emissions — the amount the entire U.S. produces in six years — over the next four decades at a cost of $7 per ton. According to the report, these reductions can be achieved simply by fulfilling the current “unmet need” for family planning, an ungainly phrase that refers to the population of couples who are married or “in union” and want contraception but lack access.
