The Port Authority of New York and New Jersey in the US has started a programme to reduce its carbon footprint by replacing older trucks that call at its terminals with newer models.

Under the authority’s phase-out plan, pre-1994 model trucks will no longer be allowed to call at Port Authority terminals from 1 January 2011.

Trucks not equipped with engines that meet or exceed 2007 federal emissions standards will no longer be able to call at the terminals from 1 January 2017.

The plan has met with criticism from the trucking industry, with some drivers claiming that while they would prefer to drive newer trucks, the associated costs would leave them out of pocket.
