TurkStream Allows Reducing GHG Emissions and Contributes to Progress towards European Climate Goals

Turkey will be able to reduce greenhouse gas (GHG) emissions by 74.5 million t of CO2 equivalent until 2030, replacing other energy sources used in electricity and heat generation with natural gas transported via the TurkStream gas pipeline. This is evidenced by the results of the research conducted by Sphera.

The company conducted a Life-Cycle Assessment (LCA) of the pipeline that transports natural gas from Russia to Turkey and Southeast Europe. The report indicates that TurkStream and the natural gas it delivers make a critical contribution to combating climate change in the region. 

The authors have analyzed different sources and routes of energy supply to Turkey and Southeastern European countries (Bulgaria, Greece, Hungary, Serbia) in terms of GHG emissions and concluded the following. 

Transporting natural gas via pipelines causes lower emissions compared to LNG transportation. The GHG emissions for the supply chains via LNG imports are 61–176% higher compared to TurkStream, depending on the source country, production method and the distance. TurkStream is more environmentally attractive  as compared to other pipelines as well. The natural gas supply from Russia via TurkStream causes approximately 30% lower emissions compared to the Ukraine Сorridor (Trans-Balkan Line).

By using TurkStream gas in Turkey instead of more pollutant fossil fuels for electricity and heat generation, 13.8% reduction in greenhouse gas emissions is possible by 2030 based on their 2017 level. If TurkStream gas is used in electricity and heat generation, the GHG savings in Bulgaria, Greece, Hungary, Serbia and Turkey can go up to 35% until 2030. In this case, Greece and Hungary approach their GHG emission targets for 2030, whereas Bulgaria and Serbia exceed their respective targets.
