Polluting buses are set to be replaced with cleaner versions next month following years of campaigning for cleaner air in Putney.

Research found diesel buses accounted for more than two thirds of the high levels of Nitrogen Dioxide (NO2) emissions in Putney High Street, believed to cause heart problems.

Next month Transport for London (TfL) will start to replace the buses with cleaner models, following two years of campaigning by the Putney Society and a joint petition with Wandsworth Council.

There are currently 177 diesel buses using the high street, with 46 of the high polluting buses to be replaced in October.

TfL plans to use 10 low emission hybrid buses, while 85 of the diesel buses will be retrofitted with catalytic converters.

It is hoped the upgrade programme will be completed by March 2013.
