Portland leaders may soon weigh whether to roll back parts of the city’s signature climate policy on replacing diesel with renewable fuels, a first-in-the-nation standard critical to reducing emissions and harmful particulate matter pollution.

The policy, adopted by the City Council in 2022 and aimed at medium and heavy trucks, phases out the sale of petroleum diesel by 2030, gradually replacing it with diesel blended with renewable fuels at increasingly higher increments.
