of the human-made climate impact; two-thirds of this impact are caused by emissions other than CO 2 , according to a new study by researchers in Europe and the US. This new study is based on a thorough review of a decade of research on aviation emissions. Aviation accounts for 3.5% —Marianne Tronstad Lund, co-author.

Freight transportation is a pillar of the US national economy, but while long-haul trucks account for less than 6% of the vehicle miles traveled over US highways, they account for about 40% of the emissions of air polluting particulate matter and about 55% of nitrogen oxides, the precursor to ozone in the atmosphere, the study said.

The climate change benefit is estimated for 2050 and human health and crop benefits are for 2030 and beyond. Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change. Global benefits from full implementation of the identified measures in 2030 compared to the reference scenario.

In its recently released Inventory of US Greenhouse Gas Emissions and Sinks: 1990 – 2011 ( earlier post ), the US Environmental Protection Agency (EPA) reported that methane (CH 4 ) emissions from the field production of natural gas have declined by 36% from 2007 to 2011 (from 83.1 CH 4 emissions represented 8.8%

Aviation climate change impacts pathway. A new study by researchers at MIT has found that factoring the non-CO 2 combustion emissions and effects into the lifecycle of a Synthetic Paraffinic Kerosene (SPK) aviation fuel can lead to a decrease in the relative environmental merit of the SPK fuel compared to conventional jet fuel.

Circle areas are proportional to values for (A and B) climate change, (C and D) human health (values for population over age 30), and (E and F) agriculture. Methane is both a potent greenhouse gas and an important precursor to ground-level ozone. Ozone, a key component of smog and also a greenhouse gas, damages crops and human health.
