The city set the bar higher for reducing greenhouse gas emissions by 2012 in a decision Wednesday.
Council revised the city's corporate greenhouse gas emissions reduction target to 30 per cent below 1990 levels by 2012 after staff reported that the city had surpassed its initial target.
As a corporate entity, the city emitted 75,131 tonnes of greenhouse gas in 2004, down from 98,886 tonnes in 1990. The largest sources of emissions were operating city buildings and running municipal vehicles.
Initiatives that led to the reduction in emissions included using an alternative fuel mix for city vehicles, implementing energy efficiency measures in city buildings and facilities and generating electricity using waste from the city's Robert O. Pickard Environmental Centre wastewater treatment plant.
