UN SYSTEM ORGANIZATIONS – GREENHOUSE GAS EMISSIONS AND REDUCTION STATUS IN 2008

35

The graphs entitled “emissions by source” and “emission by gas” illustrate how each emission source or greenhouse gas contribute to the or- ganization’s total GHG emissions. One square represents one per cent. When necessary, re- sults were rounded off manually to conserve a grand total of 100 per cent. A number of the organizations were not able to report on gases other than CO2

. The relative amounts of diff erent

greenhouse gases may change in coming years with improved data availability and refi ned methodologies.

HFCs and CFCs: It is not compulsory to report on HFCs and CFCs under the GHG Protocol. However, some organi- zations have reported them on an optional basis. In these cases, such information has been refl ect- ed in the tables.

This table indicates the level of data accuracy provided for the diff erent emission sources:

Actual data: If this box is highlighted it indicates that actual and recorded activity data, or input values, were provided for the emissions calculations. Estimated data: If this box is highlighted it indicates that actual and recorded activity data, or input values, were not available, and the GHG emissions were esti- mated by applying a set of proxies. No data: If this box is highlighted it indicates that actual and recorded data could not be identifi ed for the emission source and no estimates were made, and therefore, no emissions were reported. n/a: The emission source does not apply to the organi- zation and is therefore not relevant.
