TORONTO — Canada announced that it plans to reduce its greenhouse gas emissions by 30 percent below 2005 levels by 2030 amid international efforts to create a new framework for addressing climate change.

Prime Minister Stephen Harper’s Conservative government said Friday it formally submitted its target to the United Nations Framework Convention on Climate Change ahead of the major climate change conference in Paris in December.

The U.S. has committed to a 26 percent to 28 percent cut by 2025 from 2005 levels. The EU has a target of 35 percent below 2005 levels by 2030. Japan is proposing to cut its greenhouse gas emissions by up to 26 percent by 2030. China, the world’s largest emitter, has not officially filed its target yet, but China did set a target for the country’s emissions to peak by 2030 in an announcement with the U.S. last November.

A new international framework replacing the 1997 Kyoto Protocol is to be discussed at the Paris conference. The anti-global warming treaty has been largely ineffective because only rich countries were required to limit their emissions. Poorer countries have been reluctant to commit in a new framework.

Harper pulled Canada out of the Kyoto Protocol in 2011, saying the accord would not help solve the climate crisis. That dealt a blow to the treaty, which had not been formally renounced by any other country.

The U.S. never signed up.
