Sure. Planting urban trees is like any other climate change measure. You get two types of benefits: you get the greenhouse gas reduction—in this case, very modest storage, because there are only so many trees you can fit in a city—but you get the co-benefits of green spaces, erosion control, a bit of nature, a bit of habitat. If meeting our climate change aspirations inspires us to use all the space we can in cities to plant trees and related pieces of nature, it's the right thing to do.
I will comment on Tree Canada, because it's a superb organization that has been encouraging the planting of trees in urban areas. They call them the lungs of the cities, and anything any parliamentarians can do to encourage their continued funding I think would be a very positive move. It's a great organization and it's going in the right direction.
As a solution for our gazillion megatonnes of carbon dioxide? No.
