NOAA, partners find about 98% decline in VOCs concentrations in LA Basin over last 50 years despite 3x increase in use of gasoline and diesel

Green Car Congress

VOCs, primarily emitted from the tailpipes of vehicles, are a key ingredient in the formation of ground-level ozone which, at high levels, can harm people’s lungs and damage crops and other plants.

OptiFuel finalizing $2.6M DOE grant to demonstrate RNG hybrid line-haul locomotive

Green Car Congress

The rail sector is the only transportation modality without significant emissions related development that is feasible in the near-term to eliminate ozone, smog and GHG emissions, OptiFuel says. In comparison, OptiFuel’s 4,300 RNG hybrid line-haul locomotive is expected to emit 0.04 g/bhp-hr of NOx, a reduction of 400 times.
