Climate Action

Sustainability is not a separate pillar of our operation, but it is embedded in how the company grows, operates and creates value. Our 2025 Sustainability Statement reflects a year of steady progress, where environmental performance, social impact and governance maturity evolved together to support Greece’s transition to a cleaner and more resilient energy system.

Building on the foundations set in the previous year, the 2025 report demonstrates how sustainability is becoming increasingly integrated into decision-making, operations and long-term strategy.

Principia's Chief Financial Officer, George Koukoumelis, said:“Principia’s new Sustainability Statement demonstrates our strategy to support the energy transition, achieving high efficiency and continuing to embed sustainability at the core of our activities. With a targeted approach to development, crucial investments in new technologies, such as battery energy storage systems, as well as continuous moves to manage our environmental footprint, we are strengthening the creation of long-term value, both for our company and for society as a whole.”

Here are our significant performances in Environmental, Social and Corporate Governance issues.

Producing clean energy

Our core contribution to sustainability remains the production of clean energy. In 2025, electricity production exceeded 1,100 GWh, with 66 renewable energy plants and a total capacity of 577 MW. At the same time, the energy portfolio continued to evolve strategically. Investments in Battery Energy Storage Systems (BESS) and the electrification of the Perasma Solar Cluster in Kozani enhanced system flexibility and grid resilience, while the acquisition of 150 MW of wind assets further strengthened the company’s footprint in renewable energy.

Governance

Sustainability is fully integrated into our management structures, overseeing ESG priorities and performance, while regular reporting and internal controls ensure accountability. At the same time, we maintain a strong ethical framework. In 2025, zero incidents of corruption or bribery were recorded, supported by policies, training and monitoring systems that promote transparency and responsible business conduct. This structured governance approach enables us to translate sustainability commitments into measurable outcomes, aligning strategy with long-term value creation.

Social

In 2025, our workforce grew to 138 employees, reflecting both organizational expansion and investment in talent. A strong emphasis was placed on development, with 10,560 hours of training delivered, supporting both technical expertise and broader ESG awareness. At the same time, we maintained a workplace culture grounded in safety, inclusion and integrity, achieving zero incidents of discrimination, fines or penalties during the year.

As part of our social contribution, we implemented and supported initiatives with a substantial impact on local communities and the young generation. Among them, we supported the creation of a new Artificial Kidney Unit at the General Hospital of Karystos and the Youth Basketball Final Four in Kozani. At the same time, we proceeded with academic collaborations with Universities and Polytechnic Schools throughout Greece, continued the educational program for youth "Energy on the Go", organized book donations and strengthened the culture of giving through our Corporate Volunteering Program.

Environmental

We recorded GHG emissions intensity of 78.2 tCO₂e/€m (location-based) and 75.4 tCO₂e/€m (market-based), demonstrating a consistent focus on monitoring and managing emissions across operations. At the same time, we reinforced our circular economy approach by achieving 100% recycling of hazardous waste. We have established a net-zero transition plan targeting 2040, with intermediate milestones and structured actions covering energy sourcing, efficiency and electrification.

Creating impact beyond operations

Our Sustainability Statement for 2025 not only captures performance, but also how we evolve. We continue with the same goal: to produce clean energy, operate responsibly and create value for society, the environment and future generations.

World Environment Day (June 5) is an important reminder every year that the protection of natural wealth is a continuous, daily responsibility for all of us

With our role in the energy transition, with the way we plan and develop our projects, and with constant initiatives, we make responsibility a reality. Through our portfolio, which includes wind, solar, hydroelectric plants and now energy storage projects, we contribute to clean energy production, reducing reliance on fossil fuels and supporting a more sustainable energy future.

At the same time, we are moving forward with a clear strategy towards achieving our Net Zero goal by 2040, aspiring to achieve a 95% reduction in Scope 1 and Scope 2 emissions, and limiting residual emissions to less than 1%.

Protection of the country's natural wealth

Environmental protection is not limited to the production of green energy, but translates into respect for ecosystems, prevention, responsible operation and practical support of the areas where we operate. A crucial example is the reforestation project in Kastanologgos, in South Evia, in the area of the Kafireas Wind Cluster. Through a five-year program, we have completed the reforestation of 660 acres, giving new life to a historic chestnut forest of great ecological and cultural value.

In the same direction, we implement and support actions to protect biodiversity and strengthen local production. In the area of Kafireas, we have supported initiatives related to bees, local beekeeping and the registration of "Kissouri" honey from Karystos as a Protected Designation of Origin (PDO).

Continuous monitoring of environmental performance

We systematically invest in practices that reduce our environmental footprint. As demonstrated through the company's annual Sustainability Statement, we constantly monitor greenhouse gas emissions, record our carbon footprint and enhance energy efficiency in our projects.

At the same time, we promote responsible resource management and integrate circular economy actions into our daily operations, such as the reuse and utilization of materials. Recently, we implemented a major circular economy project, transforming the old battery covers from the construction of the "Themelio" Battery Energy Storage System into waterproof utility backpacks, which we offered to our colleagues.

Continuing the initiatives that have been implemented in the past, such as the creation of a model wooden playground from pallets and rotors used in the construction of the "Perasma" Solar Cluster, in Kozani, but also the conversion of our old materials into useful objects as part of our corporate rebranding, we highlight the importance of balancing energy, nature and local communities, recognizing that they are all part of the same ecosystem.

Daily Giving Actions

Environmental awareness is also part of our corporate culture. Through our corporate volunteering program, as well as through actions in collaboration with organizations and communities, we encourage our people to actively participate in initiatives with a positive social and environmental footprint.

World Environment Day is not just a day of information, but an opportunity to take stock of the impact of our choices and reaffirm our commitment to sustained action. We continue to work towards a more sustainable future by investing in clean energy, supporting local communities and protecting the nature that is our home.

At Principia, we are advancing with a clear strategy toward achieving Net Zero by 2040, reinforcing our commitment to sustainable growth and responsible operations in the clean energy sector.

Building on our verified 2024 carbon footprint, we have set specific interim targets for 2030, fully aligned with the goal of limiting global warming to 1.5°C, as outlined in the Paris Agreement. At the same time, as we continue to expand our portfolio—through increased installed capacity and the adoption of new technologies—we remain committed to measurable and meaningful emissions reductions.

By 2030, we aim to achieve an 88% reduction in absolute Scope 1 and Scope 2 emissions, while ensuring that 100% of the electricity consumed across our operations comes from renewable sources. In parallel, we are targeting a 10% reduction in Scope 3 emissions intensity, both per MWh produced and per MW installed.

Looking ahead to 2040, we aim to reduce Scope 1 and Scope 2 emissions by 95%, limiting any residual emissions to less than 1%. Recognizing that the largest share of our carbon footprint lies within our value chain, we place strong emphasis on collaboration with our suppliers, enhancing data transparency and developing initiatives that contribute meaningfully to Scope 3 decarbonization.

To achieve these targets, we are implementing a range of concrete mitigation measures, including the progressive electrification of our corporate fleet, the consumption of green electricity, and energy efficiency initiatives across our daily operations.

As a renewable energy producer with already very low carbon intensity, we demonstrate in practice that business growth and climate action can progress hand in hand. Our Net Zero roadmap is an integral part of our strategy for a sustainable energy future.

As part of Volunteer Day, we organized a week of social contribution and environmental responsibility

On the occasion of World Volunteer Day (5/12), we organized Community Week for another year, as part of the award-winning corporate volunteering  program Be The Hero. Our goal was to support social groups, social organizations and local communities, but also to strengthen environmental care initiatives. As demonstrated by Benevity's 2025 State of Corporate Purpose Report, the voluntary participation of employees is a key driver of increasing engagement, strengthening corporate culture and positive social impact - something that was confirmed again this year by the high participation and enthusiasm of the people of Principia.

Social and environmental contribution actions

From December 1st to 6th, our people participated in a comprehensive series of initiatives that left a tangible footprint on local communities:

• We carried out a blood donation drive in collaboration with the General Anti-Cancer – Oncology Hospital "Agios Savvas", collecting 23 bottles of blood and strengthening the company's Blood Bank.
• We created Christmas gifts, ornaments and paintings together with the children of "EEA Margarita", which will be donated to the organization's Christmas bazaar, supporting its educational programs.
• We painted and aesthetically upgraded over 500 sq.m. of living spaces at the "Athens Home for the Elderly".
• We planted over 100 trees and ensured their care for the coming years on Hymettus, in collaboration with "Trees4Greece" and the support of the Municipality of Vyronas.
• We participated in the "Boroume sti Laiki" activity at the market of Ampelokipi, collecting 430 kilos of usable surplus fruits and vegetables. The products correspond to 1,290 portions of food and were offered to the Reception and Solidarity Center of the Municipality of Athens, while their utilization prevented the release of 3.379 kilograms of CO₂ (the equivalent of 61 trips from Athens to Thessaloniki by conventional car) into the atmosphere and the waste of 5,418,000 liters of water.
• We painted and aesthetically upgraded the exterior walls of the structure of the "SOS Children's Village of Thrace" in Alexandroupolis and at the same time donated sports equipment and a professional-sized basketball hoop system.
• We performed maintenance works on the original wooden playground that we built in 2024 of the Center for Recovery - Rehabilitation, Day Care, Day Care for People with Disabilities "Kivotos", in Kozani.

Through these actions, we stood by vulnerable groups, strengthened structures that perform important work and protected the natural environment.

Lasting Practical Impact

Our Community Week proved once again the power of team giving and collective mobilization. With over 650 hours of volunteer work, our people supported social structures, helped reduce food waste, upgraded basic infrastructure for the elderly and children, and contributed to environmental restoration actions. It was a week full of meaningful work, empathy and real connection with society.

Be The Hero: A Pillar of Corporate Responsibility

The Be The Hero corporate volunteering program is a key element of our strategy for social responsibility and sustainable development. For the fourth consecutive year, it motivates our people to actively participate in social, environmental and educational initiatives. With more than 40 social actions annually across Greece, we create consistent and timeless value, strengthening our ties with local communities.

This Easter, we proved once again that we continue our commitment and acts of social solidarity, with practical support to vulnerable social groups

For Easter we collaborated with two organizations in order to rehabilitate children with disabilities, as well as to meet the needs of our fellow human beings. Thus, we showed in practice our solidarity, love and substantial contribution to vulnerable social groups.

Supporting "Chatzipaterio"

As in previous years, this Easter we carried out actions to support with the "Chatzipaterio" Center for Rehabilitation & Support of Children (K.A.S.P.), which provides special education, speech therapy and physiotherapy programs to children with disabilities.

After our volunteering action, during which we visited the Center and created gifts, made sweets and built educational toys, we donated, for yet another year, to all our employees candles to support their work. At the same time, we organized an Easter bazaar at our offices, where all employees were supplied with candles, decorations, toys and gifts.

Our employees responded to our call with enthusiasm, being present to procure the items, which had been made by the people and children of "Chatzipaterio". Through our contribution, we contribute to the strengthening of the educational and therapeutic programs of the institution.

Circular Economy for a good cause

In the bazaar, we also sold products we created by upcycling old merchandising items. The initiative was implemented in collaboration with Fabric Republic, an organization that through a surplus clothing management system, focuses on social needs, focusing on sustainable development.

We gathered bags, banners, flags, safety equipment and old clothes, and turned them into over 200 items of brand new accessories, such as pencil holders, bags, key rings and scrunchies. This initiative is a practical implementation of the principles of circular economy, while at the same time it gave us the opportunity to further strengthen our offer to "Chatzipaterio".

Long-term support to Institutions and Local Communities

These actions highlight our general series of initiatives with which we support our community.

With our initiatives, we confirm daily our commitment to actions that benefit society and local communities throughout the country. Our activities are fully aligned with the 17 UN Sustainable Development Goals, with this initiative being part of SDG: No Poverty.
