Greenhouse gas (GHG) emissions audits

The GÉANT Green Team has been carrying out audits of the greenhouse gas (GHG) emissions of NRENs and the GÉANT pan-European network. There are several gases that contribute to climate change but the biggest pollutant is Carbon Dioxide (CO2). The measure of GHG emission is usually expressed as a mass of CO2 equivalent, or tons of carbon dioxide.
 


The Green Team has adopted the ISO 14064 standard for its carbon audits. ISO defines a standard at the organisation level for quantification and reporting of GHG emissions and removals. This is inline with the objectives of the Green Team whereby each member has agreed to seek independent validation of their own network's carbon audits.

A common scheme or template for their networks has been adopted, to enable the audits to be carried out in a methodical and consistent manner. This also enables comparisons within and between NRENs, with a view to identifying key areas that need attention.

Measuring and monitoring GHG emissions are essential features of a strategy to reduce such emissions. By enabling network operators to understand the relationship between the network and CO2, the measurement process gives insights into where reductions can be made without affecting NREN service levels. The ISO-14064 standard is very useful in this regard, as it also deals with projects to improve the situation.
