CO2 intensity emissions, among the lowest generated by utilities
Iberdrola has been the only European electric utility included in the 19 editions of the prestigious Dow Jones Sustainability Index and is regarded as one of the eight top sustainable electric utilities in the world. One of the factors leading to this recognition was its 28% reduction in direct emissions in the last five years, with a total of 76% since the year 2000.
The following charts show direct CO2 emissions over the past three years.
|Specific emissions from thermal power plants (kg/MWh)||377||388||391|
|Total emissions (Mt CO2 eq)||24.3||26.7||26.6|
|Specific emissions from global mix (kg/MWh)(1)||163||187||177|
In 2018, 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 290 kg CO2/MWh2. The low intensity of Iberdrola's emissions is justified by its production mix, with 58.6% emission-free production in 2018, down 46% from 2007.
Also noteworthy is the decline in the emissions intensity of the Group's power plants from 460 kg CO2/MWh in 2015 and to 377 kg CO2/MWh in 2018.
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.
