Researchers at the London School of Economics have released an argument that posits that family planning is one of the best things we can do to fight climate change.
Every Â£4 spent on family planning over the next four decades would reduce global CO2 emissions by more than a ton, whereas a minimum of Â£19 would have to be spent on low-carbon technologies to achieve the same result, the research says.
The report, Fewer Emitter, Lower Emissions, Less Cost, concludes that family planning should be seen as one of the primary methods of emissions reduction. The UN estimates that 40 per cent of all pregnancies worldwide are unintended.
If these basic family planning needs were met, 34 gigatons (billion tonnes) of CO2 would be saved â€“ equivalent to nearly 6 times the annual emissions of the US and almost 60 times the UKâ€™s annual total.
