Forget About Climate Change, Cutting Greenhouse Gas Emissions Has 'Major Direct Health Benefits'

Forget about climate change for one moment, a series of six papers appearing in The Lancet says that reducing CO2 and other greenhouse gases has "major direct health benefits." The papers examine case studies in electricity generation, household energy use, transportation and food and agriculture and the health implications for each in both high- and low-income nations:Basically since a major part of cutting greenhouse gas emissions is switching to non-fossil fuel sources of energy, that will have corresponding air pollution benefits by reducing ground-level ozone, as well as fine particulate matter.

Black Carbon Pollution Causes 2.5 Million Deaths Annually
In terms of the latter, one paper analyses 18 years of data on the long-term health effects of black carbon pollution -- the result of older diesel engines, biomass cooking fires, and the like -- and finds that in addition to the global warming potential, this sort of particulate pollution is responsible for nearly 2.5 million deaths per year globally.

Speaking on the implications of the research, co-author on three of the papers Kirk Smith of UC Berkeley said,

Policymakers need to know that if they exert their efforts in certain directions, they can obtain important public health benefits as well as climate benefits.
Climate change threatens us all, but its impact will likely be greatest on the poorest communities in every country. Thus, it has been called the most regressive tax in human history. Carefully choosing how we reduce greenhouse gas emissions will have the added benefit of reducing global health inequalities.
