From Environmental Defence:
We wanted to get a sense of the impact Highway 413 could have on climate change and air pollution, so we hired a transportation modelling team to add up how much pollution, and how much sprawl Ontarians could be facing if Highway 413 is built.
The evidence shows that by adding hundreds of thousands of polluting cars, SUVs and trucks to Ontario’s roads, Highway 413 will make climate change worse and harm the health of people, communities, and sensitive ecosystems. It also shows how a new highway will help developers build out and not up, abandoning sustainable, dense, vibrant cities for sprawling car-dependent subdivisions that force people to travel even farther to get where they need to go.
Highway 413 locks Ontario into a high-carbon future, says Environmental Defence – CBC.ca, April 28, 2021
