As of February 2023, there is no conclusive evidence of who carried out the sabotage despite three separate investigations by Denmark, Germany, and Sweden. Gas deliveries ceased in September 2022 following the destruction of three of the pipe lines and sanctions linked to the Russian invasion of Ukraine. In October 2022, Russia confirmed that Pipe B of the Nord Stream 2 pipeline escaped destruction, and offered to resume gas supply to Europe (which was promptly declined by Berlin).

The Nord Stream explosions also resulted in the worst release of methane gas in human history, with estimates ranging from 100,000 to 400,000 tons of methane released into the atmosphere. The European Union considers the incident to be sabotage of key European energy infrastructure. On 26 September 2022, Danish and Swedish authorities reported a number of explosions at pipes A and B of the Nord Stream 1 pipeline and pipe A of the Nord Stream 2 pipeline, with the resulting damage causing significant gas leaks. German Chancellor Olaf Scholz, who had been in favour of the project, suspended its certification on 22 February 2022, following official recognition of the Donetsk People's Republic and Luhansk People's Republic by the Russian State Duma and President Putin during the prelude to the 2022 Russian invasion of Ukraine. Planning and construction of the pipeline were mired in political controversy over fears that Russia would use it for geopolitical advantage with Europe and Ukraine.

It was completed in September 2021, but has not yet entered service. The construction of the pipeline started in 2011, to expand the Nord Stream 1 line and double annual capacity to 110 billion cubic metres (3.9 trillion cubic feet). Nord Stream 2 (German–English mixed expression for 'North Stream 2' Russian: Северный поток - 2) is a 1,234-kilometre-long (767 mi) natural gas pipeline from Russia to Germany running through the Baltic Sea, financed by Gazprom and several European energy companies.
