Xi reiterates carbon emissions pledge at summit

China's President Xi Jinping reiterates his country's pledge to peak carbon emissions before 2030 and achieve carbon neutrality before 2060.

Xi spoke at the global climate summit hosted by the United States on Thursday.

He says, “We must be committed to green development. To improve the environment is to boost productivity.” Xi says developed countries, responsible for greater historical carbon emissions, should bear more responsibility for making changes at home and helping developing countries finance their transition to low-carbon economies.

He says, “We must be committed to the principle to common but differentiated responsibilities.'' Xi emphasises that China is aiming to move from peak carbon to net zero in a short time period -- just 30 years, or the span of one generation.
