New analysis has found increasing emissions of several ozone-depleting chemicals despite their production being banned for most uses under the Montreal Protocol—and a loophole in the rules is likely responsible. According to the researchers, emissions from these CFCs currently do not significantly threaten ozone recovery.

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. Schematic overview of the processes by which aviation emissions and increased cirrus cloudiness affect the climate system. Aviation accounts for 3.5% —Lee et al.

California’s latest greenhouse gas data shows that while the state continues to stay below its 2020 target for emissions, there is much more work to do to achieve carbon neutrality by 2045. California statewide GHG emissions dropped below the 2020 GHG Limit in 2016 and have remained below the 2020 GHG Limit since then.

They found that reductions in ground ozone during this 35-year period resulted in $600 million in increased production annually by the early 2010s. Another difference is that some grains can be annually modified to withstand greater heat and even higher ozone levels in the air. An open-access paper on the work appears in Nature Food.

In 2017, emissions from GHG emitting activities statewide were 424 million metric tons of CO 2 equivalent (MMTCO 2 e), 5 MMTCO 2 e lower than 2016 levels and 7 MMTCO 2 e below the 2020 GHG Limit of 431 MMTCO 2 e. The transportation sector remains the largest source of GHG emissions in the state, and saw a 1% increase in emissions in 2017.

From 2005 through 2020, total US greenhouse gas (GHG) emissions are projected to rise by 4% under a “with measures” scenario (but without a cap-and-trade program and other complementary policies), from 7,109 Tg CO 2 Eq. The report projects that transportation-related CO 2 emissions will drop 1.5% from 2005 to 2020. 6 Tg CO 2 Eq.

Radiative forcing due to perpetual constant year 2000 emissions grouped by sector for 2020 (left) and 2100 (right) showing the contribution from each species. This approach will make it easier to identify sectors for which emission reductions will be most beneficial for climate and those which may produce unintended consequences.”.
