China, the world’s largest coal consumer and producer, is in the midst of an aggressive plan to reduce the share of coal in its overall energy mix and consequent smog and greenhouse gas emissions.

As part of that strategy, Beijing announced in January its intention to shut down 800 million tonnes of outdated coal capacity by 2020.

The country has also made public recently its goal of modernizing its coal-fired power plants by 2020 in an effort to cut “polluting” emissions by 60%. The government also aims to add over 20 million kilowatts of installed wind power and more than 15 million kilowatts of installed photovoltaic power by the end of the decade.
