China CO2 emissions from coal-to-chemical industry set

China's coal-to-chemical industry could produce CO2 emissions in excess of 400 million tonnes a year by the end of the decade — a more than fourfold increase from the 90 million emitted in 2015.. Coal-to-chemical projects, which convert coal to other chemical properties, including oil and gas, are extremely carbon intensive, accounting for roughly 3% of the country's total CO2 emissions

Co 2 emission refers to a situation whereby carbon dioxide gets released into the atmosphere. The sources of this occurrence are gas, oil, and coal. They usually release CO 2 into the air during the process of producing energy. Other causes of this are the burning of wood, waste and industrial activities.

Where do the emissions go? Clean Coal Emissions

Cleaning coal and sequestering its emissions significantly raises the per-BTU price of what would otherwise be an inexpensive fuel. While selling byproducts like gypsum or commercial CO2 for sodas and dry ice can offset the price of clean coal technologies, a charge on carbon could make emission-reduction financially realistic.
