The UK Government has launched another attempt to reduce the noise limits at London's Heathrow, Gatwick and Stansted airports to below international standards. The new proposals would lower the current limits of 97dBA (day) and 89dBA (night) to 94dBA and 87dBA, although "Stage 2" aircraft approved for gradual phasing out by the European Commission would still be exempt, as would the BAC/ Aerospatiale Concorde. A court injunction prevented the previous proposals being imposed in December 1996.
