CARB Revises Emissions Data in Response to AGC Efforts

This week the California Air Resources Board (CARB) abandoned the original estimates of off-road diesel emissions that it used to establish goals for emissions reduction from off-road construction equipment. In doing so CARB essentially conceded that the "off-road rule" is not needed to meet these ambitious goals.  According to new estimates that the agency staff developed over the summer, off road fleets of diesel equipment will be far under the state's emission goals for many years to come.  CARB's action was taken in direct response to AGC's questioning of the data used in establishing the goals. If AGC gets the rule stopped in California, other states won't be able to adopt it locally.
