Zero Emission Vehicle (ZEV)

Ad Hoc Committee


RTD Ad Hoc Committees serve up to a one-year term to investigate opportunities for policy updates. In 2022, Chair Buzek formed the Zero Emission Vehicle (ZEV) Ad Hoc committee to research options for a policy to increase RTD’s Electric Bus fleet, from the current Free MallRide all electric fleet or alternatives. This page is a reflection of the of the committees work and shared resource of information gathered.


Recommend to the RTD Board of Directors a policy or set of policies to transition RTD to a zero emission fleet and reduce its Scope 1, Scope 2, and Scope 3 greenhouse gas (“GHG”) emissions as an entire agency using the Greenhouse Gas Protocol.

As defined by the Greenhouse Gas Protocol:

Strategic Priorities Alignment

Community Value - RTD strives to be a strong community partner, providing value to customers as well as to the broader Denver metro region while sustaining planet Earth. The community around us regularly strives to reduce carbon output. A transition to ZEV allows RTD to move with our community stakeholders in a transition away from GHG emitting vehicles and the fossil fuel industry.

Customer Excellence - RTD strives to consistently deliver high-quality customer service. Customers regularly ask for more sustainable vehicles. Many ZEVs require less maintenance, allowing vehicles to stay in use for longer without the same maintenance.

Employee Ownership - RTD seeks to attract and retain a highly skilled and engaged workforce. The transition to Zero Emission Buses and a more efficient agency requires cross training, training of new skills, and preparing a workforce for the future instead of holding them in the past.

Financial Success - RTD takes very seriously the management of all financial resources. While the upfront investment in renewable sources, energy efficiency, low emission buses may be higher than using traditional sources, many of these same investments save funds in the long run through reduced future costs. Over time, this allows RTD to make investments now that will last through our future.
