Prime Minister Justin Trudeau has set ambitious targets for reducing emissions in Canada but his government has faced criticism over a lack of details for those plans.

The legislation fulfills a promise in the 2019 election to be more aggressive at cutting greenhouse gas emissions by 2030, and get Canada to net-zero emissions by 2050.

Among the priority areas are agricultural infrastructure in Western Canada and broadband to expand access to high-speed internet service across the country.

The world's heaviest polluters increased their carbon emissions this year, despite a global effort to fight climate change.
