This short article from the Canadian Broadcasting Corporation is based on an interview with David Miller, former mayor of Toronto and now director of international diplomacy for the C40 Cities Climate Leadership Group. Here's an excerpt:
Research by C40, a network of 94 global cities committed to addressing climate change, shows about 70 per cent of the world's greenhouse gas emissions come from urban areas.
It's predominantly from four sources:
- How we generate electricity.
- How we heat and cool buildings.
- How we manage our waste.
In a recent interview, Miller laid out which cities he believes are leading the way with innovative ideas — and results.
Oslo, for example, has a climate budget, which is managed by the city's finance department and runs alongside the normal budgeting process. According to C40, Oslo city council can only approve spending plans that have a realistic chance of hitting their emission-reduction targets.
So if you want to build, say, a new curling rink, Miller said, you have to consider how much carbon that rink will use. "And if there isn't a carbon budget, the same way if there isn't a financial budget, you can't do it."
