Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

For offsets to be credible, a ton of CO 2 -equivalent emissions from an offset project should equate to a ton reduced from a covered emission source, such as a smokestack or exhaust pipe. To be credible, as noted above, an offset should equate to an emission reduction from a direct emission source, such as a smokestack or exhaust pipe.

Study Concludes That to Limit Global Warming to 2 °C, Less Than 25% of Proven Fossil Fuel Reserves Can be Burnt Between Now and 2050

Green Car Congress

The theme of the current issue of Nature is that the climate situation may be even worse than you think. Less than a quarter of the proven fossil fuel reserves can be burnt and emitted between now and 2050, if global warming is to be limited to two degrees Celsius (2 °C), according to a new study published in the journal Nature today.

DLR: cleaner aircraft emissions reduce the climate impact of contrail cirrus

Green Car Congress

Fewer soot particles in the exhaust stream of aircraft reduces the formation of ice crystals and therefore the climate impact of the resulting contrail cirrus. The results are published in an open-access paper in the Nature Partner Journal (npj) Climate and Atmospheric Science.

Joint Research Centre review concludes no serious risk in use of R1234yf MAC refrigerant under normal and foreseeable conditions

Green Car Congress

Europe has banned the use of the refrigerant R134a in new vehicles because of its high global warming potential (GWP). Testing was in three steps: Pre-test on highway to determine the maximum temperature of the vehicles T max , measured at the exhaust manifold or turbocharger by driving at the vehicles’ maximum speed (about 180 to 190 km/h).
