As required by law, mining company Rio Tinto estimates the carbon and warmening impact of planned coal mining expansion in the Hunter Valley:
Rio Tinto subsidiary Coal & Allied says that if the project is approved, an additional 155MT CO2e [carbon dioxide equivalent] will be emitted over the life of the mine (taking account of direct mining-related emissions and emissions from coal transport and combustion).
“It was determined that over the life of the mine, the emissions resulting from the project as distinct from currently approved mining at Hunter Valley Operations, will raise the global surface temperature by 0.000078°C.”
“It is considered a reasonable assumption that if the coal was not produced at Hunter Valley Operations, an alternative mine would increase production to meet demand, therefore equivalent emissions would occur.”
