Interesting fact: The government agency responsible for the national roads in New Zealand (i.e. big roads that aren't the responsibility of the local government) is the largest purchaser of native tree seedlings in New Zealand (I can't find a source for this online, but I am reliably informed it's true). I've seen a lot of motorway berms that were previously grass, converted to native plants. This not only captures carbon, but reduces carbon emissions by taking away the need to mow the grass, and it doesn't require 'new' land.
