The United States, Canada and Mexico said Monday they would put in place infrastructure to cooperate on greenhouse gas emissions trading as part of efforts to fight climate change.

We will build capacity and infrastructure with a view to facilitate future cooperation in emissions trading systems, building on our current respective work in this area, the three countries said in a statement.

They also said they would work toward reducing emissions from the transport sector, including by striving to achieve carbon-neutral growth in the North American aviation sector in the context of global action.
