CUMMINS' PARTNERSHIPS AND ITS POLICY ADVOCACY EFFORTS PLAY KEY ROLES IN THE COMPANY'S ENVIRONMENTAL PERFORMANCE.
They help Cummins meet product emissions goals, use energy more efficiently and bring environmental solutions to the marketplace.
Four of the company’s 10 environmental sustainability principles focus on partnerships with legislative and regulatory entities to develop sound public policy that reduces Cummins’ impact on the environment. They are:
- Help develop responsible regulations.
- Promote technology development.
- Advocate for incentives to accelerate progress.
- Support a balanced global approach.
Cummins worked closely with the U.S. government and a variety of stakeholders, for example, to develop the first-ever greenhouse gas (GHG) and fuel-efficiency standards in the United States in 2014 for medium- and heavy-duty commercial vehicles and engines. These standards became known as the “Phase 1 Rule.”
The company is now working to help shape future Phase 2 standards. When the U.S. Environmental Protection Agency (EPA) and the Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) released their joint Phase 2 proposal in June 2015, Cummins announced its support for the rulemaking, testifying at a public hearing and submitting detailed written comments.
A key aspect for Phase 2 is to maintain the same regulatory structure with separate standards for the engine and the rest of the vehicle. Separate standards are critical for the regulation to achieve environmental and user benefits while recognizing the diversity and complexity of the commercial vehicle sector.
The company’s engagement on future regulations will not end with finalization of the Phase 2 Rule expected later in 2016, nor is it limited to just the U.S.
For example, the California Air Resources Board’s (CARB) call for lower on-highway engine oxides of nitrogen (NOx) standards and plans by countries to adopt tougher Euro NOx standards mean Cummins will continue to share technical and policy expertise in partnership with its stakeholders around the world.
Cummins longstanding partnerships with the U.S. Department of Energy (DOE) and other federal and state agencies directly support international goals of reducing GHG emissions and national goals of reducing petroleum consumption and dependency.
These partnerships help Cummins lead the United States and other markets in energy productivity while continuing to reduce criteria emissions from global transportation and distributed power generation fleets.
The company’s current public-private projects involving DOE, except where noted, include:
- The Cummins-led SLTNR (Sustained Low Temperature NOx Reduction) project, which partners with Johnson-Matthey and the Pacific Northwest National Laboratory. Progress continues on the Selective Catalytic Reduction (SCR) catalyst and reductant delivery technologies capable of sustained 90 percent NOx conversion at 150 degree C. The goal is improved robustness of future high performance NOx aftertreatment systems under challenging conditions.
- The EDPCI (E85/Diesel Premixed Compression Ignition) project’s goal is to demonstrate high efficiency dual-fuel engine operation in a Class 8 (long-haul) truck. The project wants to achieve a more than 50 percent reduction in petroleum consumption by making extensive use of E85 (85 percent ethanol/15 percent gasoline) and diesel fuel. Completion of engine development, vehicle integration, and demonstration testing is expected in 2016.
- The 55BTE Program goal is to demonstrate 55 percent brake thermal efficiency (BTE) in a diesel-only configuration by building on lessons from the SuperTruck program.The 55BTE program will lay critical groundwork for a future SuperTruck project to advance the performance, cost, and commercial viability of a suite of engine / powertrain and vehicle technologies.
- The HHP-NG 55BTE program is developing advanced knock suppression technology for high horsepower natural gas engines. That is a key enabler for a series of other technology, defining a path to a 55 percent BTE target for large, stationary electrical power generation systems.
