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.

The European Parliament is calling for fast action to reduce non-CO 2 climate forcers including black carbon soot, hydrofluorocarbons (HFCs), methane, and ground-level ozone, which together are responsible for nearly half of climate forcing. Even cutting CO 2 emissions to zero today will not produce cooling for a thousand years.

Among the non-CO 2 pollutants are hydrofluorocarbons (HFCs), methane, tropospheric ozone, and black carbon soot. Ramanathan and Victor highlight the importance of aggressively reducing CO 2 emissions, but note that the road ahead will be long, difficult, and expensive, and that “in the meantime, a fast-action plan is needed.”

The future of the Earth could rest on potentially dangerous and unproven geo-engineering technologies unless emissions of carbon dioxide can be greatly reduced, the latest Royal Society report has found. SRM techniques act by reflecting the sun’s energy away from Earth, meaning they lower temperatures rapidly, but do not affect CO2 levels.
