In September 2005, Gazprom, BASF, and E.ON signed a basic agreement on the construction of a North European gas pipeline. In November 2005, the North European Gas Pipeline Company (later Nord Stream AG) was incorporated in Zug, Switzerland. In December 2005, Gazprom started construction of the Russian onshore segment of the Nord Stream project, in order to connect Nord Stream with the wider Russian natural gas pipeline system. Specifically, the Gryazovets–Vyborg gas pipeline was built in Babayevo, Vologda Oblast,{{cite press release |publisher=Gazprom |title=Gazprom launches construction of onshore section of North European Gas Pipeline |url=https://www.gazprom.com/press/news/2005/december/article63374/ |date=9 December 2005 |access-date=3 August 2007 |archive-date=23 December 2011 |archive-url=https://web.archive.org/web/20111223081934/http://gazprom.com/press/news/2005/december/article63374/ |url-status=dead }} connecting Nord Stream to the Northern Lights Pipeline network. The construction was completed in 2010.

In October 2006, the pipeline and the operating company were officially renamed Nord Stream AG.

The environmental impact assessment started in November 2006, when notifications were sent to Russia, Finland, Sweden, Denmark, and Germany as parties of origin (countries whose exclusive economic zones or territorial waters the pipeline was planned to pass through), and Poland, Latvia, Lithuania, and Estonia as affected parties. The final report on transboundary environmental impact assessment was delivered in March 2009.

On 25 July 2022, Gazprom announced it would reduce gas flows to Germany to 20% of the maximum capacity, or 50% of the current throughput. The company shut down the pipeline for 10 days because of maintenance and claimed the reduction was due to a repaired turbine in Montréal, Canada, that could not be delivered due to sanctions against Russia. The German government denied this claim and believed there was no reason for reducing the flow. Meanwhile, during a press conference in Tehran, Putin said that these flows could be increased again if Russia receives more turbines from the manufacturer.[https://www.nytimes.com/2022/07/20/business/energy-environment/nordstream-vladimir-putin-russian-gas.html "Seeking Leverage Over Europe, Putin Says Russian Gas Flow Will Resume]" NYT.

On 31 August 2022, Gazprom halted any gas delivery through Nord Stream 1 for three days, officially because of maintenance.{{Cite news |last=Cooban |first=Anna |date=31 August 2022 |title=Russia cuts more gas supplies to Europe as inflation hits another record |url=https://www.cnn.com/2022/08/31/business/nord-stream-1-europe-inflation/index.html |access-date= |website=CNN}} On 2 September 2022, the company announced that natural gas supplies via the Nord Stream 1 pipeline would remain shut off indefinitely until the main gas turbine at the Portovaya compressor station near St Petersburg was fixed due to an engine oil leak.{{Cite news |date=2022-09-02 |title=Gazprom: Nord Stream 1 gas to stay shut until fault fixed, "workshop conditions needed" |language=en |work=Reuters |url=https://www.reuters.com/business/energy/gazprom-nord-stream-1-gas-stay-shut-until-turbine-fault-fixed-no-timeline-given-2022-09-02/ }} Gazprom justified this by claiming that European Union sanctions against Russia had resulted in technical problems, preventing it from providing the full volume of contracted gas through the pipeline; Siemens Energy, which maintains the turbine, rejected this and stated that there are no legal obstacles to its provision of maintenance for the pipeline.

In his book The New Cold War: Putin's Russia and the Threat to the West, published in 2008, Edward Lucas stated, "though Nord Stream's backers insist that the project is business pure and simple, this would be easier to believe if it were more transparent".

In a report published by the Fridtjof Nansen Institute in 2008, Norwegian researcher Bendik Solum Whist noted that Nord Stream AG was incorporated in Switzerland, "whose strict banking secrecy laws makes the project less transparent than it would have been if based within the EU". Secondly, the Russian energy sector "in general lacks transparency" and Gazprom "is no exception".

Russian responses have argued that the pipeline increases Europe's energy security and that the criticism is caused by bitterness about the loss of significant transit revenues, as well as the loss of political influence that stems from the transit countries' ability to hold Russian gas supplies to Western Europe hostage to their local political agendas.{{cite news | url = http://news.bbc.co.uk/2/hi/europe/4226296.stm | title = Baltic deal worries Polish press | work = BBC News | date = 8 September 2005| access-date = 18 March 2008}} As the first direct connection to Western Europe, the Nord Stream pipeline would reduce Russia's dependence on the transit countries.

The Portovaya compressor station in Russia at the beginning of Nord Stream 1, with a rating of 366 megawatts, is estimated to produce around {{convert|1.5|e6t|e9lb|abbr=off}} of {{co2}} emissions per year,[http://www.gazprom.de/projects/nord-stream/ Nord Stream] {{Webarchive|url=https://web.archive.org/web/20201202115532/http://www.gazprom.de/projects/nord-stream/ |date=2 December 2020 }} Retrieved on 7 September 2020, with 40% efficiency of the gas turbines not including other compressor stations for the gas pipelines within Russia.

Since the pressure loss is proportional to the square of the flow velocity, dividing an unchanged gas transport volume between two Nord Stream systems could save around {{frac|3|4}} of the pumping effort and presumably avoid more than {{convert|1|e6t|e9lb|abbr=off}} of {{co2}} emissions annually. Using the discounted {{co2}} damage costs of {{convert|180|€/t|€/lb}} from the German Environment Agency{{nbsp}}({{lang|de|Umweltbundesamt}}),{{cite web |url=https://www.umweltbundesamt.de/presse/pressemitteilungen/hohe-kosten-durch-unterlassenen-umweltschutz |title=Hohe Kosten durch unterlassenen Umweltschutz |work=Umweltbundesamt |date=20 November 2018 }} this would, after a rough estimate,{{by whom|date=June 2021}}{{citation needed|date=June 2021}} enable the third tube to be amortized within around 20 years from a global point of view. The fourth tube could also possibly be amortized in the hypothetical case of overall optimization of gas flow over various pipelines between Russia and the EU.

The production of over {{convert|2|e6t|e9lb|abbr=off}} of steel for the Nord Stream 2 tubes resulted in more than {{convert|3|e6t|e9lb|abbr=off}} of {{co2}} emissions, not including the concrete-coating and the associated pipeline sections onshore.{{citation needed|date=June 2021}}

Before construction, there were concerns that during construction the seabed would be disturbed, dislodging World War II-era naval mines and toxic materials including chemical waste, chemical munitions, and other items dumped in the Baltic Sea in the past decades, and thereby toxic substances could surface from the seabed and damage the Baltics' particularly sensitive ecosystem.{{cite news

A ship in the Bay of Greifswald is one of twenty sunk in 1715 by the Swedish navy to create a physical barrier across the shallow entrance to the bay's coastal lagoon.{{cite press release |publisher = Nord Stream AG |title = Underwater Investigation of Wreck on Greifswalder Bodden Enters Second Phase |url = http://www.nord-stream.com/en/press0/press-releases-special/wreck-survey.html |date = 31 October 2008 |access-date = 11 January 2009
