“The global landscape of engine emission regulations is at a crossroads,” AEM Vice Chair Leif Magnusson told participants in a Stage 5 engine emissions webinar last week.

Magnusson hosted the webinar as chair of AEM’s Engine Emissions Task Force, formed earlier this year in response to member feedback on the challenges of addressing current and proposed regulatory requirements.

“As global providers of equipment, AEM members face countless regulatory challenges in order to compete in specific markets,” he told listeners.

To help members deal with these challenges, key documents on Stage 5 regulations have been posted to the AEM website, he said, along with a link to the webinar recording (member password needed to login).

Primary Focus on Particulate Matter

Sigrid de Vries, secretary general, Committee for European Construction Equipment (CECE), told webinar participants that the new Stage 5 regulations would focus primarily on diesel particulate matter. She said the directive would also affect a greater range of engine power categories than before, including both smaller and larger horsepower classes.

De Vries said CECE concerns included lack of a provision for replacement engines and the shortness of the Stage 5 transition period.

Because the regulations are set to go into effect in 2019, CECE is calling for their adoption by the end of 2015 in order to give manufacturers as much time as possible to adjust. An additional six-month transition period is also being requested, she said.

Engine Makers Could Drive U.S. Adoption

While U.S. regulators have yet to show their cards, there’s little doubt that stricter Stage 5 diesel emission regulations will soon find their way from Europe to America, said CE Sector Board member and Diesel Progress publisher Mike Osenga, the webinar’s third speaker.

Osenga said one factor driving adoption is the realities facing engine manufacturers. Currently, Europe and the U.S. share common emissions standards, he said. If Europe adopts Stage 5, it would make sense for engine manufacturers if Tier 5 was adopted in the U.S. as well.

Osenga said he believed Tier 5 would reach the U.S. by 2019 or 2020, with impetus for the regulation coming not from the U.S. Environmental Protection Agency (EPA), but from the California Air Resources Board (CARB).
