Tehran’s buses shift towards biodiesel

In Iran, Tehran is turning to biodiesel to help reduce carbon emissions in its public transport sector, with 20 out of 300 buses running on biodiesel. The move is part of a wider policy to reduce air pollution including the introduction of cleaner fuel standards, mitigating air pollution using funds generated by a green tax, and seeking to increase use of public transport in addition to other measures. The addition of diesel particle filters will also be made to all of the buses in the fleet.
