A team of civil engineers has conducted a detailed analysis of 22 cities from around the world, which could help policymakers choose the right tools to combat climate change on a municipal level. Depending on their climate, industrial base and population densities, cities can use a variety of tools and techniques to lower their carbon emissions. For example cities in cold-climates, like Toronto, can retrofit buildings to reduce heating costs, while cities with access to low-carbon sources of electricity (e.g. hydropower) can replace fossil fuels with the low-carbon alternative.
