Petitions, studies, opinions, and complaints

What is a petition to the European Parliament and why was one submitted for the Prinos CCS project?

A petition to the European Parliament is a formal institutional mechanism that allows citizens and organizations of the European Union to address the Parliament directly when they consider that EU law is being infringed or is at risk of being infringed, or that European action is required to protect the public interest.

The procedure is based on Article 227 of the Treaty on the Functioning of the EU (TFEU) and Article 44 of the Charter of Fundamental Rights of the EU, which guarantee the right of petition to every citizen or resident of a Member State.

It works as follows:

1. Submission of the petition

The petition is submitted electronically to the European Parliament’s Committee on Petitions (PETI), with full documentation and a clear reference to the European policies or legislation concerned.

2. Admissibility check

The Committee examines whether the issue falls within the EU’s remit. If so, the petition is deemed admissible and remains open for examination.

3. Examination and action

The Committee on Petitions may:

      • request information from the European Commission or national authorities,
      • organize a hearing in the European Parliament,
      • propose an on-the-spot mission or a resolution,
      • refer the matter to other parliamentary committees (e.g. ENVI or ITRE).

The Thasos Coordination Committee and the Kavala Citizens’ Initiative initiated this petition. The report on the CO₂ storage project in Prinos was submitted with the aim of ensuring that the project is developed in full compliance with the European regulatory framework for CCS, with transparency, equal access, and proper use of European resources.

This is a democratic and institutional control process, which is not directed against CCS technology, but aims to ensure the legitimacy, safety, and trust of citizens in the new CO₂ capture and storage technology in Greece.

 

Here are all the documents from the dossier that the Thasos Coordinating Committee and the Kavala Initiative submitted to the European Parliament for hearing.

Mr. Yannis Economides is a Mechanical Engineer who has already completed 4 decades of professional activity and is one of the three members of the interdisciplinary team (Prof. Lazaros Vassiliadis and Prof. Th. Karapantsios) that was set up by the Municipality of Thassos to support on a technical level its negative attitude and its great concerns in the implementation of such a project. In the following opinion, Mr Economides analyses the extent of the risks arising from the implementation of the project in Prinos. The risks are extremely high and the most critical ones in his view are UNMANAGED. Their impact will be dramatic not only on the environment but on the lives of the people of the region for millennia to come.

The study of Mr.Economides was submitted on behalf of the Municipality of Thassos by the Mayor of Thassos Mr.Kyriakidis to the Ministry of Environment and Energy with the appeal to issue a negative opinion on the draft permit of the project.

On the seismicity and the resulting risk for the CO2 storage project in Prinos

The natural geological repository is not the work of man, it has existed for millions of years and the risk of its geological structure being disturbed by an earthquake or an induced earthquake is always present.
Here is an analysis by Lazarus Vassiliadis on the role and risk of seismicity in the work of Prinos.

14 reasons why we reject CCS and are against CO2 storage in Prinos

The technology has not been sufficiently tested. We don't want to be the guinea pigs!

 

CCS technology has not been sufficiently tested on a large and long-term scale, especially in geological conditions such as those of the Prinos region. International experience is limited and existing projects operate with government subsidies and without clear proof of viability. Installing such technology in a sensitive tourist and environmental area without full scientific documentation and social consensus is an irresponsible risk. Local communities should not be used as test beds or guinea pigs for technologies of dubious performance and safety. Here τα αποτελέσματα της έκθεσης του Institute for Energy Economics and Financial Analysis.

The CO2 Reservoir is located very close to the island and in the area of Kavala Bay. This alone increases the risk enormously!

The proximity of the reservoirs is the most strategic factor for our region in combination with the high seismicity, 𝙨𝙝𝙤𝙬 𝙨𝙩𝙤𝙥𝙥𝙚𝙧, 𝞽𝞸 𝞳𝞴𝞮𝞲𝞭ί 𝞹𝞸𝞾 𝞹𝞺έ𝞹𝞮𝞲 𝞶𝞪 𝞼𝞽𝞪𝞵𝞪𝞽ή𝞼𝞮𝞲 𝞽𝞸 𝙨𝙝𝙤𝙬, the key to why we say NO to CCS Prinos. Is it a coincidence that even the originators of the technology, the Norwegians who also have huge economic benefits from CCS, are building similar facilities 150+ km from their shores?

 

We live very close to a tectonically active area

Of course, ifCO2 storagehad the same “lifetime” horizon as oil pumping (50 years) the risk would be limited because the earthquake is a stochastic phenomenon (its time variation is not known) and is therefore approximated probabilistically. But this is not the case in the case of the Prinos, the storage will be in perpetuity and the occurrence of a major earthquake is very likely or even certain.”

Lazaros Vassiliadis

We have no confidence in the quality standards according to which the CO2 will be injected.

We look towards the Tempi and we are frightened about the security rules of the Greek State!!!!!! This is why trust in the State has been lost.

State without prevention

The state seemed incapable of protecting even the most basic right: life. Citizens saw that security systems either did not exist or did not work, that warnings had been ignored for years, that negligence had become the norm.

Concealment, not accountability

Instead of an honest attitude, the government attempted to shift the responsibility to one person, the stationmaster. This move was seen by many as an attempt to cover up the systemic problem and reinforced the feeling of betrayal.

The timelessness of decadence

The case of Tempe revealed that the problem was not a momentary one. It was the result of decades of opacity, political impunity and administrative negligence, with many governments bearing responsibility.

The state as “other”

But the most painful thing was that the State appeared to the citizens as something foreign, alienated. A state that does not protect, does not hold itself accountable and does not correct itself cannot inspire trust.

Anger and assertion

The mobilisations that followed were not just expressions of mourning. They were cries of indignation from a society that can no longer bear the normality of the accident, the familiarity of the fatal. The slogan “It wasn’t an accident – it was a crime” encapsulated the moral dimension of the loss of trust.

Trust in the State was not lost in Tempe. It had already been eroded – the accident merely exposed it. And regaining it will not come through communication moves or temporary measures. It will require catharsis, truth and a radical change of mindset at every level of government.

The pollutants they want to bury come not only from Greece, but from all over southern Europe!!

The quantities of CO₂ destined for storage in Prinos do not only come from Greek emission sources, but possibly also from Southern European countries. Thassos risks becoming a transnational pollutant dumping ground, taking disproportionate environmental and geopolitical risks without sufficient benefits for itself. Such a scenario increases the sense of injustice in local communities, calls into question the principle of environmental justice and makes the region an unacceptable energy risk pocket for the whole Mediterranean.

 

CCS is a sham solution and a technologically dangerous method that prevents the phasing out of fossil fuels and therefore hinders the energy transition.

Carbon Capture and Storage (CCS) technology, instead of being a means to solve the climate crisis, tends to function as a pretend solution. It is used to keep the current fossil fuel-based energy model alive without addressing the root of the problem.

It is a technologically unstable and potentially dangerous method, both because of the uncertainty about the long-term safety of storage, and because of the risk of undermining the push for complete decarbonisation.

Ultimately, such “solutions” delay the sustainable energy transition, absorb public resources and reinforce the logic of shifting responsibility to the future. Every billion € investment in CCS takes away from renewable energy sources.

Here are some examples of projects that have failed or are being sold as successful while there are huge constipated operations.

 

 

Systemic Risks: If CO2 is stored underground, the permanence of the CO2 injected cannot be guaranteed. New systemic risks are created that will eventually be borne by future generations as a perpetual burden.

Underground storage of CO₂ does not guarantee the permanence of trapped carbon. No geological system can be considered absolutely stable over centuries. The potential for leaks, micro-earthquakes or destabilisation of existing structures is real and potentially catastrophic. The management of stored quantities of CO₂ requires continuous monitoring and technological support over many decades. Future generations will be asked to shoulder the burden of maintenance or dealing with potential failures without responsibility for creating the problem. CCS introduces a new type of “perpetual cost”. Here are the systemic risks we see in Prino.

As the pressure spreads, groundwater up to 100 km away can become saline or contaminated with heavy metals, making it unsuitable for drinking water production and agriculture.

Injecting CO₂ into underground geological strata can cause significant stresses that spread over long distances. This has direct and potentially irreversible consequences for:

  • the production of drinking water
  • agriculture and the rural economy
  • public health and health security

The protection of the aquifer is a non-negotiable public interest, and no technology should take precedence over it. The following is the general outline of pressures planned in the Prino.

 

Further industrialisation of the coastal area and the destruction of the marine environment also has a negative impact on tourism.

The further industrialisation of the coastal zone and the possible destruction of the marine environment due to the installation of CCS infrastructure have significant negative consequences, not only for tourism.

 

There are no studies on the compatibility and symbiosis between tourism supply and long-term CO2 injection.

The coexistence of the CCS project in Prinos with tourism in the region of Thassos and Kavala raises a number of disadvantages, which mainly concern public perception, environmental safety, and economic impacts, such as:

  1. Negative perception of tourists – “Semantic pollution”
  • The presence of a CO₂ storage project can distort the image of the region as a “clean” and “pristine” destination.
  • Some visitors may be put off by the proximity to an industrial/energy project, even if there is no immediate risk.
  1. Environmental fear and safety concerns
  • PossibleCO₂leaks , seismicity or seismic events that the injection itself will create cause fears in the local community and visitors.
  • Tourism in Thassos is also based on the image of ecological stability – a leak or even a reputation for danger can damage the brand.
  1. Impact on branding of the destination
  • Thassos and Kavala are promoted as “green” and traditional destinations. The existence of an industrial CO₂ storage facility contradicts this image.
  • The brand “Prinos CCS” in the media is negatively associated with Thassos
  1. Fall in values of tourist properties
  • CCS is associated with pollution so this may lead to land and property devaluation in tourist areas, mainly near Prinos or Kavala.
  1. Social tension and negative publicity
  • Any protest or opposition to CCS can attract negative press, which will deter tourists.
  • There is a risk that the project could be associated with a picture of social or environmental instability.
Acidification of water bodies. The release of CO2 acidifies water. Acidification leads to local impoverishment of biodiversity. Only a few species survive at high CO2 levels. Fish are destroyed!!!

High release risks Many studies point to the risk of so-called blowouts "sudden explosions/explosions". These are sudden, uncontrolled releases of CO₂ that can occur due to an increase in pressure. Controlling these explosions is much more difficult at sea than on land.

Many scientific studies highlight the risk of so-called blowouts – sudden and uncontrolled explosions or releases of CO₂ from storage tanks. These explosions are caused by a sudden increase in pressure and are extremely difficult to control, especially when storage takes place in an underwater environment. Managing and preventing such events is technically more demanding and risky at sea than on land, significantly increasing the risks to the environment and local communities.

 

Monitoring/Monitoring. During the project and for centuries after the storage facility is operational, the site must be monitored for permanent sealing.

The CO₂ storage company will be responsible for monitoring the site for approximately 30 to 40 years during the life of the project. This monitoring includes continuous monitoring for the safety, tightness and integrity of the geological formations where the CO₂ is stored.

However, the scientific community and international regulations point out that, even after the active monitoring phase has ended, the site will need to be monitored for many centuries. This long-term monitoring is necessary to ensure that CO₂ does not escape, thus preventing potentially catastrophic environmental and health impacts.

The long-term nature of this responsibility raises important issues:

  • Financial burden: who will finance this monitoring after the end of the corporate responsibility?
  • Legal and institutional uncertainty: Who is liable in case of future spills or accidents?
  • Technical challenges: Continuous monitoring requires advanced technological tools and continuous evaluation over time.
  • Environmental safety: failure to ensure watertightness poses risks of contamination of aquifers, air pollution and other impacts.

Therefore, the assumption that liability is limited to 30-40 years is misleading and insufficient to ensure the environmental safety and sustainability of the project.

 

London Protocol How will EnEarth and the government verify that clean CO2 is stored and that the predefined low levels of radioactivity allowed by the London Protocol are met?

The London Protocol requires rigorous monitoring and verification of the quality of CO₂ stored underwater, including:

  • Verification that the stored gas is pure CO₂, free of hazardous impurities or radioactive elements.
  • Compliance with predefined radioactivity limits, in accordance with the standards set by the Protocol, to exclude the risk of contamination of the marine environment.

EnEarth and the Greek government must implement:

  • Systematic protocols for sampling and analysis of CO₂ before and during infusion.
  • Independent audits and third-party certifications to ensure transparency and compliance.
  • Continuous monitoring of radiation levels at the storage site and in the wider marine area.
  • Public disclosure of results to enhance social trust and avoid complaints or disputes.

Without rigorous and transparent controls, compliance with the Protocol’s standards and environmental protection cannot be guaranteed.
