Professor Kirk R. Smith, writing at Forbes:

The fracking furor over shale gas is the latest in a series of environmental debates that have bedeviled the oil and gas industry in spite of what might be considered an enviable record compared to related industries, coal for example. From off shore spills to the Keystone Pipeline, the industry probably feels a bit set upon at times. Similarly, its products are often the focus of environmental concern and consequent strict regulation, for example diesel air pollution. Finally, it often bears the brunt of concerns about carbon dioxide emissions leading to climate change risks.

The industry might keep in mind, however, that one of its products, liquefied petroleum gas (LPG — bottled gas containing propane and butane), is actually the most effective solution available for the largest environmental health risk in the world: cooking with solid fuels.


There is some opposition in the environmental community to promoting LPG, a fossil fuel, because of climate concerns. In reality, however, because of the poor combustion typical in biomass stoves, which produces black carbon, methane, and other climate-active pollutants, and the often non-renewable nature of the biomass supplies, which results in CO2 emissions, the net climate impact of a switch to LPG would be negligible. Even if only considering CO2, the incremental impact on global emissions of a switch to LPG would be no more than a percent of the emissions from the developed sector globally. It is not cooking by the poor that poses risk to the climate.
