Customers often ask us many questions about natural gas.

  • What is natural gas?
  • How does natural gas reduce fleet emissions?
  • Can I calculate the emission reductions with natural gas?
  • What engines are available for my operation? What about costs and maintenance?

Welcome to the Natural Gas Playbook – Cummins Westport’s new website designed to provide new and existing natural gas customers with guidance on evaluating and operating natural gas vehicles.

The information is separated into five sections: Assess, Specify, Prepare, Implement, and Operate & Maintain. We provide emissions and economic calculators, resources, tools, and information to help you successfully manage your natural gas fleet. You can also save and print information specific to your playbook.
