Carbon Reduction Commitment

The AMEE category at /business/energy/stationaryCombustion/crc includes CO₂emissions data for the use of a variety of energy types/fuels specified in the UK Government's Carbon Reduction Commitment initiative which commences in April 2010.

Under this scheme, organisations which use at least one Half Hourly electricity meter and greater than 6,000 MWh of electricity per year are required to report on the CO₂ emissions associated with their total energy consumption (electricity + other energy sources) except that associated with transport or onward supply.

This category provides emissions calculations based on the data and calculating methodology specified in the latest (22nd January 2010) documentation published by the Department of Energy & Climate Change.

To use this category, use drill-downs to specify the type of fuel, then enter the quantity used in one of the following profile item values:

• energyUsed
• massUsed
• volumeUsed

The CRC source documentation does not specify fuel densities or heating (calorific) values and therefore the basis in which fuel quantities are specified (energy, mass, volume) is not interchangable for each given fuel. AMEE follows CRC protocol in requiring quantities to be specified on a basis according to the particular fuel type chosen. Entering a quantity in an inappropriate form for a given fuel type will result in a zero value. The appropriate profile item values for each energy/fuel type are as follows:

The correct basis (energy, mass, volume) for specifying quantities is additionally described in the basis data item value for each fuel type and therefore accessible directly through the API. Also compliant with CRC recommendations are the CO₂ emissions factors for diesel, kerosene, LPG, petrol and electricity found in the /home/energy/quantity category within AMEE.

Note on data sources

Six new fuel types (basic oxygen steel gas, cement industry coal, commercial/public sector coal, lignite, peat and waste oils) are included with respect to those specified in the previous documentation (the Consultation on Draft Order to Implement the Carbon Reduction Commitment). Two fuels not included in the latest documentation but which appeared in the previous Draft documentation ('refinery miscellaneous', 'lubricants') are preserved in this category but should not be considered compliant with current CRC protocol.
