CO₂ Emissions

The primary source of CO₂ emissions from the facility is the combustion of natural gas for power generation required to support operational activities. Emissions are systematically monitored and quantified in accordance with the EU Emissions Trading System (EU ETS), ensuring full compliance with applicable regulatory requirements.

All reported emissions are calculated based on the approved Monitoring Methodology Plan, as mandated under the EU ETS framework, ensuring transparency, accuracy, and consistency in emissions reporting.

The Company is committed to minimizing its carbon footprint through the continuous improvement of energy efficiency. To this end, energy-saving systems have been implemented, and traditional combustion-based processes have been progressively optimized or replaced with more environmentally friendly alternatives.

These measures have resulted in a measurable reduction in CO₂ emissions, supporting the Company’s broader environmental and sustainability objectives.

Furthermore, the facility maximizes the utilization of Boil-Off Gas (BOG) generated during LNG operations, significantly reducing the need for additional fuel combustion and contributing to lower overall greenhouse gas emissions.

Through these actions, the Company actively supports the transition towards cleaner energy solutions while ensuring safe and efficient operations.

Water Quality

The Company implements a comprehensive Water Quality monitoring programme in accordance with the requirements set out in the approved Environmental Terms and Conditions (AEPΟ). Monitoring is carried out at multiple sampling stations surrounding the facility, covering all seasons of the year.

The programme includes the systematic assessment of key physicochemical parameters, such as temperature, pH, residual chlorine, and dissolved metals, ensuring a robust evaluation of the marine environment.

Sampling and analysis are performed using accredited methodologies, combined with in‑situ measurements and laboratory testing, ensuring high accuracy and reliability of results.

The monitoring results to date indicate that water quality parameters remain within expected natural ranges and are consistent with regional baseline conditions. No systematic trends are identified across sampling locations at varying distances from the facility.

The findings confirm that there is no evidence of degradation or localized impact on the marine environment associated with the operation of the installation.

This ongoing monitoring programme provides a reliable baseline for detecting potential changes over time and supports the Company’s commitment to protecting the marine ecosystem.

Ecosystem Ecological Status Monitoring

The Company implements a comprehensive monitoring programme to assess the ecological status of the marine ecosystem, in full compliance with the applicable environmental permit requirements.

The programme is based on the systematic evaluation of key biological indicators, including phytoplankton biomass (chlorophyll‑a), benthic macrofauna, seabird populations, and marine mammals. These indicators collectively provide an integrated picture of ecosystem health across multiple trophic levels.

Monitoring activities combine in situ measurements, satellite observations, visual surveys, and advanced acoustic techniques, ensuring a robust and scientifically validated assessment approach.

Field surveys are conducted throughout the year, capturing seasonal variability in species distribution, abundance, and ecological conditions within the wider study area.

The results indicate that the ecological status of the marine environment remains within expected natural variability, reflecting the influence of regional oceanographic processes rather than localized operational impacts.

No evidence of systematic changes or degradation in biological indicators has been identified in relation to the operation of the facility.

This continuous monitoring framework supports the early identification of potential impacts and enables the implementation of appropriate mitigation measures where required.

Through this programme, the Company demonstrates its ongoing commitment to protecting marine biodiversity and ensuring the sustainable operation of its activities.

Ambient Noise

The Company implements a structured ambient noise monitoring programme in accordance with the requirements of the approved Environmental Terms and Conditions (AEPΟ), ensuring continuous assessment of noise levels associated with the facility’s operation.

Noise measurements are conducted at multiple locations, including on the floating unit, within a 500 m radius, and along the coastal zone, using internationally recognized standards (ISO 1996 series).

Monitoring results indicate that ambient noise levels in the marine environment surrounding the facility remain low, with measurements at 500 m ranging between approximately 48.5 and 49.7 dB(A), well below the regulatory limit of 70 dB(A).

At coastal locations, recorded noise levels are primarily attributed to natural sources, such as wave activity, with no contribution from the operation of the facility.

Further offshore, noise levels decrease significantly, reflecting background environmental conditions rather than operational influences.

These findings confirm that the operation of the facility does not result in elevated ambient noise levels or measurable impact on the surrounding environment.

The continuous monitoring programme ensures early detection of any potential changes and supports the Company’s commitment to minimizing noise emissions and protecting the surrounding marine and coastal environment.

The Alexandroupolis INGS operates in close connection with the local community and the wider region.

From the earliest design stages, The Alexandroupolis INGS operates in close connection with the local community and the wider region. Every phase of the project was implemented in close cooperation with national authorities and local stakeholders (Regional Unit, Municipality, Port Authority, Fire Brigade, General Secretariat for Civil Protection, etc.), ensuring transparency, accountability, and operational effectiveness.

Beyond its strategic energy role, the project contributes to local economic and social development by creating employment opportunities, supporting local entrepreneurship, and improving access to competitive energy. Particular focus is placed on strengthening local skills and workforce development, ensuring that the benefits generated by the project extend directly to the community. At the same time, initiatives linked to the project promote education, innovation, and regional visibility through scientific, educational, and cultural activities.

These initiatives form the core of Gastrade’s Corporate Social Responsibility programme, Energy for the Future, which focuses on empowering younger generations, fostering collaboration, and creating long-term value for the local community.

Our aspiration is to be an active part of the city that hosts us, building relationships of trust, supporting local progress and contributing to a more resilient, inclusive and sustainable future, especially for the generations to come.
