Last month, the leaders of three North American countries met for the annual so-called “Three Amigos Summit.” One of the results coming out of the summit was a pledge to reduce emissions, by promising to get at least half of the continent’s power from carbon-neutral sources by 2025.

Now, it appears Canada may be on the cusp of making a national carbon price, as Canada’s Environment Minister Catherine McKenna indicated to Bloomberg last week that the country’s upcoming emissions reduction plan would include a carbon price.

Speculation continues as to whether a carbon tax or cap-and-trade system will actually be required of every province, several of which have opposed such a plan. Andrew Light, a senior fellow at the World Resources Institute, said the minister’s statements did not clarify definitively whether a national plan will be instituted.
