Clean Cities Lifecycle GHG Reduction in Heavy-Duty Vehicles

This chart compares well-to-wheels greenhouse gas (GHG) emissions of various fuels for Heavy-Duty Vehicles (HDVs) to a diesel baseline, as captured by the Clean Cities Program. The GHG emissions were derived from Argonne National Laboratory's Greenhouse gases, Regulated Emissions and Energy use in Transportation (GREET) tool. Renewable Natural Gas (RNG) produced from wastewater treatment and converted landfill gas is the most effective in reducing GHG emissions since it captures the GHG methane that would otherwise be directly emitted to the atmosphere. Alternative fuels tend to be more advantageous when replacing gasoline than compared to replacing diesel because spark-ignited gasoline is not as efficient as compression-ignited diesel. See Clean Cities Lifecycle GHG Reduction in Light-Duty Vehicles for GHG reductions in light-duty vehicles as captured by the Clean Cities Program.
