Subcommittee participants share professional and technical expertise on air pollution control technologies by participating in regular conference calls. The Blue Skyways Collaborative is composed of six subcommittees that focus on specific areas of air emissions. The subcommittees are: 

• On-road (diesel trucks, school buses)

• Non-road (construction and agriculture equipment)

• Fuels (ethanol and biodiesel)

• Air/Water/Rail (reducing emissions at congested nodes)

• Energy (energy efficiency/renewable energy)

• Outreach (education, attracting partners, and funding identification)
