Clean Diesel Collaboratives
Reducing diesel emissions is a shared responsibility. Collaboration has been the hallmark of successful clean diesel programs. A successful program brings together the right people from government, environmental and community organizations, fleet owners/operators, private industry, and other stakeholders.
As part of the National Clean Diesel Campaign, seven regional collaboratives across the nation work to leverage funds and take a local approach to mitigating diesel emissions. These Clean Diesel Collaboratives are diverse, multi-stakeholder groups that provide technical assistance, foster partnerships, and identify and leverage resources.
The Clean Diesel Collaboratives are public-private partnerships that include EPA regional offices as well as equipment manufacturers, fleet owners, state and local governments, and non-profit organizations.
