The Green Tank voted in favor during the tenth written evaluation process conducted by the Hellenic Managing Authority (EYDAM) under the 2021–2027 Just Transition Development Program (JTDP). The submitted dossier included two projects. The first project concerns energy upgrade works for public and municipal buildings in the North and South Aegean regions, with a total budget of €10 million (€6.854 million for the North Aegean and €3.154 million for the South Aegean).

In 2025, emissions from the ever-polluting lignite plants fell to a historic low (3.68 million tons), while those from gas plants reached a historic high of 8.8 million tons. As a result, total emissions from the power generation sector remained at the same level as in 2024, reaching 15.75 million tons, which is 5.55 million tons above the target set in the NECP for the same year (10.2 million tons). Despite the stagnation in total emissions, the sector's carbon intensity fell to a new low (264.7 g CO2/kWh), due to the increase in the country's total electricity production, part of

In his article for Oikologiki Enimerosi (Ecologica News), Nikos Mantzaris, Policy Lead Analyst and Co-Founder of The Green Tank, examines the progress of Greece’s lignite phase-out and assesses whether it has been accompanied by a truly just and socially responsible transition for lignite-dependent regions.

In 2025, renewables (mainly wind & solar) set a production record, covering 46.7% of electricity demand, despite high curtailments (1,867 GWh), while lignite recorded a historic low (2,723 GWh). At the same time, production from fossil gas reached a historic high (23.3 TWh), which was partly channeled into electricity exports, which also reached a historic high (3 TWh). On the other hand, domestic demand was down compared to 2024, reaching 56.5 TWh. High dependence on expensive fossil gas and the partial utilization of cheap RES resulted in the average price on the wholesale electricity market in 2025 reaching 104.1 €/MWh, an

The Green Tank, together with other environmental NGOs, was invited by the European Commission to provide input for the upcoming EU Semester report and recommendations for Greece. Our submission highlighted key gaps in the country’s energy policy and proposed concrete actions to ensure a fair, sustainable, and citizen-focused energy transition.

Two online meetings on the implementation of EU Regulation 2024/1991 on Nature Restoration in Greece were held on 18 December 2025, organized by the Ministry of Environment and Energy (MoEE) and the Goulandris Natural History Museum / Hellenic Center for Wetlands (EMFHG-EKBY), in collaboration with The Green Tank.

At the public discussion “Talking with the World (Kosmos),” organized by the political party Kosmos on January 22, 2026, to address energy poverty, Ioanna Souka, Energy Policy Analyst at The Green Tank, stressed that energy poverty in Greece is a particularly serious social problem. According to Eurostat and the EU Energy Poverty Advisory Hub, Greece records the highest values across four key energy poverty indicators reflecting socioeconomic impacts and living conditions.

As part of the State of Climate in Greece for 2025, conducted by scientists from the Institute for Environmental Research and Sustainable Development at the National Observatory of Athens and organized by the Climatebook information hub, Nikos Mantzaris presented the results of the Green Tank analysis for the electricity generation sector.

The European Commission launched a public consultation on a new legislative initiative for CO₂ markets and infrastructure, as part of the EU strategy for industrial decarbonisation. The Green Tank submitted its views, stressing that the development of CO₂ markets and infrastructure can play a meaningful role in the industrial transition only if it is strictly limited to processes that are genuinely hard to decarbonise.

A new scientific study examines the reasons why Greece’s system of protected areas continues to face serious challenges, despite repeated institutional reforms and improved administrative coordination in recent years.

In 2025, domestic gas consumption reached a historic high of 70.2 TWh. 70.3% came from the power generation sector, which recorded a record 49.3 TWh, followed by networks with 13.1 TWh. Industry had the lowest consumption at 7.8 TWh (-13.5% compared to 2024). LNG had the largest share of imports (32.7 TWh), surpassing Russian gas (27.6 TWh). Exports in 2025 (8.6 TWh) tripled compared to those in 2024. More than 90% of exported gas was channeled through the same gate as Russian gas imports (Sidirokastro).

In November 2025, emissions from power plants reached 1.16 million tons, and the sector's carbon intensity was 250 g CO2/kWh, an improvement of 7.7% compared to October. However, in the first 11 months of 2025 total emissions reached 14.07 million tons, mainly due to high emissions from gas-fired power plants, which were the second highest since 2021 and accounted for 55.7% of total emissions for the period. Ag. Dimitrios was the top polluter with 2.3 million tons of CO2 for the 11-month period.

In an article as part of a special edition with ELIAMEP’s forecasts for 2026, published in Ta Nea, titled “Climate crisis heating up, climate policy in retreat”, Nikos Mantzaris, Chief Policy Analyst and co-founder of The Green Tank, examines one of the defining contradictions of our time: while the climate crisis is intensifying at an accelerating pace, climate policy at both European and national level is retreating dangerously.

In the first 11 months of 2025, we had record production from RES (24,595 GWh) and natural gas (20,864 GWh), record net exports (2,409 GWh), but also record RES curtailments, which reached 1,863 GWh and were more than double those of the same period in 2024 (886 GWh). In November specifically, RES ranked first in electricity production with 2,072 GWh, followed by gas with 1,778 GWh, while net exports doubled compared to October, reaching 477 GWh. The monthly average wholesale electricity price was 106.5 €/MWh.
