§ Sir Robert Smith
To ask the Secretary of State for Environment, Food and Rural Affairs if she will conduct an environmental impact assessment across the supply chain to assess whether the aggregates levy meets the Government's sustainable development objectives; and if she will publish the results of this assessment in the library. 
§ Mr. Paul Boateng
I have been asked to reply.
The aggregates levy will be subject to environmental evaluation in due course, as part of the Budget process. Given that the levy was only introduced on 1 April 2002 it is currently too early to assess its impact.
