CO2 intensity emissions, among the lowest generated by utilities
The following charts show direct CO2 emissions over the past three years.
|Specific emissions from thermal power plants (kg/MWh)||391||460||476|
|Total volume (Mt)||25.1||31.6||30.1|
|Specific emissions from global mix (kg/MWh)(1)||176||225||212|
In 2016, CO2 emissions per MWh generated were among the lowest at the national and international level. For the purposes of comparison, the specific emissions of European electricity companies are 311 kg/MWh2. The low intensity of Iberdrola's emissions is justified by its production mix, with 57.1% emission-free production in 2016, down 42% from 2007.
Also noteworthy is the decline in the emissions intensity of the Group's power plants in the last three years, from 476 kg CO2/MWh in 2014, to 460 kg CO2/MWh in 2015 and to 391 kg CO2/MWh in 2016.
The main greenhouse gas generated by the Company's activities is CO2, from combustion during thermal power generation. Iberdrola has made a pledge to the public to remain amongst the main European companies with the fewest CO2 emissions per kWh. The Company's strategy is essentially to gradually cut back on its GHG emissions by continuing to generate power from renewable sources, while gradually incorporating the most efficient and least carbon intensive technologies at its existing facilities.

(*) The Group has a large hydroelectric production capacity. Annual production using this technology depends on rainfall and the capacity of reservoirs during certain periods, which vary greatly. Consequently, the use of other technologies in global production also varies.
