Emissions of potent GHG HFC-23 have grown, contradicting reports of huge reductions

Green Car Congress

Now, an international team of researchers have shown, in an open-access paper published in the journal Nature Communications , that concentrations were increasing at an all-time record by 2018. When we saw the reports of enormous emissions reductions from India and China, we were excited to take a close look at the atmospheric data.

Calif. ARB releases GHG scoping plan update; more ZEVs, “LEV IV”, MD and HD regulations; ZEV for trucks; more LCFS

Green Car Congress

Mandatory regional criteria pollutant reduction targets will be established in the 2016 State Implementation Plans (SIPs) with expected reductions on the order of 90% below 2010 levels in the South Coast and similar reductions in the San Joaquin Valley by the year 2032. In 2014, ARB will propose enhancements to strengthen the LCFS.
