Methane, ozone, and human lives in simulation

By running computer simulations looking at methane and ozone levels, Princeton University scientists estimate that approximately 370,000 lives will be saved between 2010 and 2030.

Methane is a greenhouse gas that contributes to the rising levels of ozone in the atmosphere. By controlling methane emissions, we can control ozone levels. This study looked at health benefits and controlling methane emissions, and found that a mere 20% reduction in methane levels starting in 2010 would save thousands of lives world-wide.

In another encouraging finding, the scientists looked at the cost associated with reducing methane levels and estimated it at approximately $420,000 per saved life (remember, this is over a 20-year period). Without going into the maths too much, they go on to show that the cost is actually very reasonable.
