Tailpipe Pollution Standards Could Cut Emissions 80%

Extending the vehicle emissions and fuel-quality standards already in place in the largest global vehicle markets would reduce near-term climate impacts through reductions in black carbon and other short-lived climate pollutants by the equivalent of 710 million metric tons of CO2 annually, according to a report by the International Council on Clean Transportation (ICCT). This represents an 80 percent reduction compared to current emissions levels.

The Impact of Stringent Fuel and Vehicle Standards on Premature Mortality and Emissions also quantifies direct tailpipe emissions’ health impacts and finds that policy action can avert more than 210,000 early deaths in 2030.

The study’s estimate of public health and environmental benefits would be substantially increased if additional impacts were included, such as exposure to secondary pollutants formed in the atmosphere (including particles and ozone), emissions in rural areas, and emissions from marine, aviation and off-road equipment, ICCT says.

The report’s authors say the goal should be tailpipe emission standards equivalent to the most stringent rules adopted in Europe, so-called Euro 6/IV standards, in tandem with ultra-low-sulfur fuel (no more than 10 parts per million sulfur), by no later than 2025.

The report comes as the 19th conference of the UN Framework Convention on Climate Change in Warsaw enters its second and final week. Delegates made little progress overall in the first week, the Irish Times reports.

And UN talks at the climate conference on setting up new carbon markets, and creating global standards for such markets, have been postponed until June 2014.
