PM Trudeau urges the world to have 60 per cent of the world's greenhouse gas emissions covered by a price by 2030

World leaders at the UN climate summit are promising to protect the world's forests, cut methane emissions and help South Africa wean itself off coal.

Britain is hailing the commitment by over 100 countries, including Canada, to end deforestation in the coming decade as the first big achievement of the conference known as COP-26.

Meanwhile, the U-S is launching a plan to reduce methane emissions, a potent greenhouse gas that contributes significantly to global warming.

Prime Minister Justin Trudeau used his speech at the opening of an event on carbon pricing to urge the world to have 60 per cent of the world's greenhouse gas emissions covered by a price on pollution by 2030.
