Ashland uses The Greenhouse Gas Protocol: A Corporate Accounting and Reporting Standard for guiding the reporting of energy and greenhouse gas emissions. Ashland primarily tracks its energy consumption through the number of million British Thermal Units (BTUs) of energy used. For reporting purposes we convert this number to gigajoules (GJ) for both our direct and indirect energy consumption.
Direct energy consumption is the amount of primary energy combusted on site by Ashland. Direct energy sources include natural gas, coal, liquefied petroleum gas, diesel and fuel oils, and gasoline.
Indirect energy refers to the energy consumed by Ashland that is generated by and purchased from external suppliers. Ashland consumes indirect energy through electricity and steam.
In 2015, Ashland direct and indirect energy consumption decreased as a result of the discontinuation of combusting coal at our Calvert City, Kentucky facility and the divestiture of Pt. Neches, Texas.

Improving Our Energy Efficiency
At Ashland, we are constantly looking for ways to improve our energy efficiency and to invest in energy efficiency improvement projects in our existing facilities. Ashland has completed many projects aimed at improving energy efficiency and reducing emissions as summarized below:
