The noble Baroness is not quite right. There are a number of measures and the United Kingdom has worked incredibly hard to try to meet these; for example, on particulate matter, which is very significant, the UK met EU requirements for the PM10 measure in 2011. In addition, 22 out of 27 states are struggling to meet the nitrogen dioxide directive, largely because of problems with diesel vehicles. So across the board countries are finding this a challenge. We are working very hard to ensure that we comply, aiming for later this decade.
