News of the agreement came the same day U.S. President Barack Obama and Canadian Prime Minister Justin Trudeau held a joint press conference on the White House lawn, the first such meeting between the two countries' leaders in nearly two decades
Before Thursday's visit, Obama and Trudeau agreed to cut methane gas emissions by 40% to 45% below 2012 levels by 2025. As part of the agreement, both countries will also develop new regulations for methane, a powerful greenhouse gas.
For the White House, the agreement with Canada is seen as a way to meet U.S. goals set at last year's climate summit in Paris. In February, Obama's plan to limit climate change faced a major setback when the Supreme Court delayed legislation intended to cut emissions from power plants.
