The City Delta project

As part of the Clean Air For Europe (CAFE) programme, the so-called ‘City Delta project’ commenced in early 2002. The programme, as the name suggests, is designed to develop relationships between regional scale air quality levels and the levels found in cities using state-of-the-art models.

These relationships will be incorporated into ‘RAINS’, the Integrated Assessment Model (IAM), which is being used in the CAFE Programme to examine various emission reduction scenarios as input to policy development. For the first time this will enable the IAM to be used to develop optimum control strategies which simultaneously address both urban and regional scale residual air quality problems in the EU.
