Context
The leaking of the Nord Stream natural gas pipeline under the Baltic Sea is the biggest single event that led to the massive release of climate-damaging methane. But the incident is a “drop in the ocean compared to the amount of methane released globally,” found the United Nations Environment Programme (UNEP).
About
About methane:
- Methane is a rapidly accelerating part of the climate problem.
- It is the primary component of natural gas, and it warms the planet more than 80 times as quickly as a comparable volume of atmospheric CO2 over a comparable amount of time.
- Sources of Methane:
- Biological Sources
- Agriculture
- Paddy rice cultivation
- Emissions from Fuel and Industries
Methane stays in the atmosphere for only ten years, unlike CO2, which persists for hundreds or thousands of years.

What is Nord stream project?
- Owned by the Russian energy giant, Gazprom, Nord Stream Pipeline is the longest subsea pipeline.
- It is an export gas pipeline that runs under the Baltic Sea carrying gas from Russia to Europe.
- The gas for Nord Steam comes mainly from the Bovanenkovo oil and gas condensate deposit in Western Siberia.
- Nord Stream consists of two pipelines, which have two lines each.
- Nord Stream 1 that runs from Vyborg in Russia to Lubmin in Germany was completed in 2011.
- Nord Stream 2 that runs from Ust-Luga in Russia to Lubmin in Germany was completed in 2021.
- Both the pipelines together can transport a combined total of 110 billion cubic metres of gas a year to Europe for at least 50 years.
- The Nord Stream crosses the Exclusive Economic Zones (EEZs) of several countries including Russia, Finland, Sweden, Denmark and Germany, and the territorial waters of Russia, Denmark, and Germany.
- While both pipelines are not currently running commercially, they had millions of cubic metres of gas stored in them.
The leak event:
- Two leaks were detected on the Nord Stream 1 pipeline, both in an area northeast of the Danish island of Bornholm.
- Sweden had reported two separate underwater explosions, very close to where the leaks occurred.
- Possible causes of the leak- The investigations have not yet revealed the cause behind the leaks.
- Possible causes range from technical malfunctions to a lack of maintenance, to even possibly sabotage (deliberate damage or destruction of equipment or property which belongs to the enemy).
- The European Union (EU) and North Atlantic Treaty Organisation (NATO) called the leaks acts of sabotage.
- Russia, which controls the pipeline, has not ruled out sabotage either.
- Ukraine said the leaks were likely the result of a terrorist attack carried out by Russia.
- Various European countries, such as Sweden and Denmark, have launched separate investigations into the matter.

Concerns
- Economic impact- European gas prices immediately spiked after the reports of the leaks emerged.
- As a result of the leak, all the stored gas is escaping.
- The pipelines are unlikely to provide any gas to Europe through the forthcoming winter months.
- Depending on the intensity of the damage caused by these ruptures, permanent closure of the Nord Stream lines was also a possibility.
- Environmental impact- Methane is a large component of natural gas and is also a potent greenhouse gas.
- It is the second-largest contributor to climate change after CO2.
- Other impacts- Vessels could lose buoyancy if they enter the area, and there might be a risk of leaked gas igniting over the water and in the air.
