Cummins Westport's new Natural Gas Playbook is a website to give new and existing natural gas customers guidance on evaluating and operating CWI-powered natural gas vehicles.

Located at, the five-step Natural Gas Playbook features information and tips on how to assess, specify, prepare, implement, and operate/maintain a CWI-powered natural gas fleet. The website provides answers for fleets that have questions about operating natural gas vehicles.

The Natural Gas Playbook answers questions such as:

  • What is natural gas and how does it reduce fleet emissions?
  • Can I calculate the emission reductions with natural gas?
  • What are zero carbon renewable fuels?
  • How do natural gas engines operate, and what about my application and the operational costs and maintenance requirements?

In addition to tips and tools for CWI products, the playbook also offers the opportunity to connect with Cummins and CWI experts to answer questions and support the adoption of natural gas into truck, refuse, school bus and transit applications.

The site features two new calculators.

The Greenhouse Gas Emissions Calculator calculator is based on three published North American well-to-wheel GHG Models: GREET, GREET California, and GHGenius. It provides the carbon dioxide equivalent WTW emission reductions possible with the use of natural gas or renewable natural gas in a variety of applications.

The Payback Calculator is a tool to calculate fuel savings, average fleet speed, service intervals, and fuel system capacity requirements.
