All TriMet buses running on routes throughout the tri-county Portland metro area are now powered by a much cleaner-burning fuel—renewable diesel.
TriMet is using a blend of 99% renewable diesel and 1% petroleum.
The change in fuels will reduce the carbon dioxide equivalent emissions coming from an individual bus by nearly 99%.
When factoring in the upstream emissions of making and delivering the R99 to TriMet’s facilities, the move to R99 will lower the greenhouse gas emissions from TriMet’s fixed-route bus fleet by about 61% compared to the biodiesel blend we had been using.
