Toronto By Night On the Civic front the Mayor of the City of Toronto, David Miller, last week announced a program which will encourage public participation in diminishing their own CO2 footprints. Earlier this year the city of Toronto organized a green roof competition featuring public and private structures. A short-term pilot program - The Green Roof Incentive Pilot Program - was developed to support residential, commercial and institutional construction of a variety of types of green roofs. This new program, called ZEROFOOTPRINT is software based. A Toronto NGO, Zerofootprint has created an online calculator designed to help citizens reduce their environmental impact. its a combination of an environmental footprint calculator and a web based social network based on technology developed by a company named Business Objects. "The tool graphically illustrates the impact of every day activities," says Mayor Miller," it will help our citizens make Toronto one of the greener cities on the planet."

Climate change and the fact that the majority of the world's people now live in cities can make calculators like this one an important tool any citizen can use to start making a change for the better.
