The federal government has published new draft regulations that will force oil and gas companies to slash their greenhouse gas emissions.

The Trudeau government has focused on the oil and gas production industries because the large amounts of energy they use make them the country’s largest source of greenhouse gases.

Oil and gas is Canada's highest-polluting industry and its emissions continue to rise, undercutting progress in many other parts of the economy. Ottawa will likely fall short of its commitment to reduce emissions by 40-45% from 2005 levels by 2030 unless the oil and gas sector intensifies efforts to decarbonize.

By David Ljunggren OTTAWA (Reuters) -Canada will on Monday unveil the details of its long-awaited plan to cap emissions of greenhouse gases from the oil and gas sector, an idea that the energy industry and some provinces strongly oppose.

The cap on energy-sector emissions is a longstanding promise from Canada’s Liberal government. The Business Council of Canada said the cap would pose a headwind for an economy struggling to record growth.

OTTAWA (Reuters) -Canada will on Monday unveil the details of its long-awaited plan to cap emissions of greenhouse gases from the oil and gas sector, an idea which the energy industry and some provinces strongly oppose.

Oil and gas producers in Canada will be required to cut greenhouse gas emissions by about one-third over the next eight years under new regulations published Monday. The government is also going to establish a cap-and-trade system that Environment Minister Steven Guilbeault said will reward lower-emitting producers and incentivize higher-polluting ones to do more.
