North American Climate, Clean Energy, and Environment Partnership Action Plan
The White House (under President Barack Obama) | June 29, 2016
The North American Climate, Energy, and Environment Partnership was announced by Prime Minister Justin Trudeau, President Barack Obama, and President Enrique Peña Nieto on June 29, 2016, at the North American Leaders Summit in Ottawa, Canada. This Action Plan identifies the deliverables to be achieved and activities to be pursued by the three countries as part of this enduring Partnership.
Even though White House priorities concerning this promise in particular might have changed drastically since President Trump assumed office in January 2017, it's worth noting the action plan mentioned here was negotiated and put into effect with the US and Mexico in June 2016, which technically fulfils this promise.
