At long last, two countries that share a border will also share a comprehensive plan for climate action.

Serious climate conversations between the U.S. and Canada have been few and far between over the years. This week, the two countries are expected to present a unified front with a climate change agreement, a rare event, given that they have long been on opposite ends of the climate action spectrum.

The two nations’ leaders, U.S. President Barack Obama and Canadian Prime Minister Justin Trudeau, will announce a series of joint measures this week during a meeting at the White House. According to The Guardian, the agreement is expected to include pledge to cut up to 45 percent of methane emissions — a greenhouse gas that is roughly 80 times more potent than carbon dioxide — from oil and gas industries. During a White House press call on Tuesday, Todd Stern, U.S. special envoy for climate change, said that the meeting would focus on short-lived pollutants like methane, hydrofluorocarbons (potent greenhouse gases used in refrigerators, aerosols, and air conditioners), and black carbon (a particulate component of soot). Officials also expect the agreement to call for a decrease in diesel fuel and more funding for Arctic climate research.
