scope:

The present document defines field implementation of a so-called Global Key Performance Indicator (Global KPI) enabling the monitoring of Carbon Intensity in all ICT sites including, but not limited to, data centres and operator sites.

The present document addresses Carbon usage performance due to energy usage by operational infrastructures in ICT sites. The present document does not deal with other C0₂ emissions related to ICT equipment manufacturing, transportation and end of life.

The present document deals with CO₂ equivalent emissions (CO₂eq) resulting from final energy consumption by ICT sites or group of sites. It does not deal with other GHG gas emissions coming from equipment leakages such as described in the Directive F-Gas EU-517-2014 [i.7].

Energy consumption should not to be confused with power generation. Only CO₂eq emission coming from energy actually consumed by the ICT site is considered. Use of excess locally generated power is out of the scope of the present document.

The Global KPI alone is not designed for comparison of ICT sites or group of sites. It does not define an ICT site as good or bad unless combined with other parameters considered relevant for a comparison, such as local climatic conditions, availability requirements or purpose of ICT site.

The present document addresses in a simple way the equivalent carbon of following objectives defined in ETSI EN 305 200-2-1 [1] for data centres, ETSI EN 305 200-2-2 [2] for fixed networks and ETSI EN 305 200-2-3 [3] for mobile networks using four objective KPIs:

• Greenhouse gas emissions

• Effectiveness of energy generation over greenhouse gas emissions

• Avoided greenhouse gas emission

• Reused greenhouse gas emission
