Greenhouse gases and other gases emissions

Greenhouse gases and other gases emissions

OTE launched, in 2007, a program for monitoring greenhouse gases (GHG) and other gases emissions arising from its operation on a national and regional level but also at individual buildings level.

The calculation of GHG emissions is based on the methods described in the GHG Protocol developed by the World Business Council for Sustainable Development (WBCSD) and the World Resources Institute (WRI). The GHG and other gases emissions inventory of OTE includes direct emissions (scope 1) from fuel consumption in OTE owned / controlled installations, vehicles, etc., and indirect emissions (scope 2) from electricity and district heating consumption.

In 2010, total GHG emissions from energy consumption were estimated at 322,749 t CO2 eq (direct emissions, i.e. emissions due to fuel consumption from sources owned or controlled by OTE, account for 4% of the total), presenting an increase of 6% compared to 2009. This increase is mainly attributed to the increased (by 7% compared to 2009) electricity consumption.

Comment: GHG emissions and other gases emissions from electricity consumption are estimated on the basis of the latest emissions inventory (covering the period 1990 – 2009) submitted to the European Commission by the Greek ministry for the Environment and the national energy balance for 2009.

For 2010 Particulate Matter (PM) and VOC emissions were also estimated. PM emissions amounted to 190 t and VOC emissions amounted to 60 t.
