This text considers the contribution that alternative fuels and technologies can offer in terms of reducing the impact of road transport on air quality and climate change and the role of Government in developing the market and infrastructure for these fuels and technologies. Alternative fuels and improvements in petrol and diesel technology can offer both air quality and greenhouse gas benefits. Although some fuels and technologies will offer greater benefits for air quality than for climate change (and vice versa), focusing fuels and technologies where the benefits they provide are most needed should help to ensure any potential conflictsbetween air quality and climate change objectives are minimised. |
