The carbon footprint of electricity production – June 2026
Record low emissions for Greece’s electricity sector in the first half of 2026 (6.95 million tons), due to the interconnection of Crete. The sector’s carbon intensity was also at record low levels both in June 2026 (183.1 g CO2/kWh), and in the first half of 2026 (217.8 CO2/kWh) due to record production from renewables and large hydro, as well as reduced oil use in Crete. Despite the progress, Greece is off track to achieve its NECP commitments due to the maintenance of high fossil gas use.
Energy policy in an era of geopolitical instability
In an article published in the GREEK ENERGY 2026 annual print edition of energypress.gr, Nikos Mantzaris, Senior Policy Analyst and Co-founder of The Green Tank, examines how growing geopolitical instability is reshaping Europe's energy policy.
Trends in electricity production – June 2026
In the first half of 2026, clean electricity generation (RES & large hydro) reached a record high of 18,791 GWh. It exceeded the production from the three fossil fuels combined by 5,709 GWh, despite the fact that 9.6% (1,601 GWh) of total RES generation was curtailed. From April -when they started operation- to June, batteries prevented only 2.2% of the curtailments, while they reduced gas production by just 0.6%. Fossil gas remained at high levels with 10,706 GWh and only 195 GWh lower production than the 2025 record, while net exports increased almost sevenfold compared to the first half of
Bringing Life to the Mediterranean: The ARTEMIS Documentary Series on Seagrass Restoration
The ARTEMIS documentary series takes viewers on a journey across the Mediterranean, showcasing how science, innovation, policy and local communities can work together to protect and restore some of the region's most valuable marine habitats: seagrass meadows.
The silent battle for the EU LIFE Programme
In a joint op-ed published in Kathimerini, Nadia Andreanidou (MEDASSET) and Ioli Christopoulou (The Green Tank) highlight the vital role of the LIFE Programme—the EU's only funding instrument dedicated exclusively to nature, biodiversity, and climate action.
EU ETS revision: climate and competitiveness can go hand in hand
Following the European Commission’s proposal to revise the EU Emissions Trading System (EU ETS), Stavros Gennitsaris, Industrial Policy Associate at The Green Tank, explains in his energypress.gr article, “Revising the EU ETS: the choice is not between climate and competitiveness,” why maintaining a strong and credible EU ETS is not an obstacle to industrial competitiveness, but a prerequisite for it.
The Green Tank Newsletter #2 | April-June 2026
In this issue, we bring together the latest highlights from our work on energy, climate, nature and Just Transition. From Posidonia seagrass meadows and marine ecosystems to electricity prices, carbon emissions and fossil gas, and from power generation to buildings, transport and industry, we connect the different pieces of a transition that is moving forward—but not always at the same pace for everyone.
The Green Tank on Radio City on the importance and restoration of Posidonia meadows
Ioli Christopoulou, Policy Director and co-founder of The Green Tank, spoke on the Radio City programme on Athens 9.84 about the importance of Posidonia meadows for biodiversity, coastal protection and climate resilience, as well as the need to strengthen restoration efforts in Greece and across the Mediterranean.
The first three months of battery storage in Greece’s electricity market
In a new article for energypress titled “An ‘X-ray’ of the marκet three months after the launch of operation of the first batteries”, Nikos Mantzaris, Lead Policy Analyst and Co-Founder of The Green Tank, analyses data from the first three months of battery storage operation (April–June 2026) and assesses their contribution to the electricity market.
Just Transition Newsletter #11
The eleventh issue of The Green Tank's newsletter has been published, covering developments over the past six months related to the Just Transition of lignite regions in Greece and across Europe (January–June 2026).
Just Transition: Funding for Greece’s lignite regions must continue under the 2028–2034 Partnership Agreement
Funding for the transition of Greece's lignite regions must continue during the next programming period (2028–2034). This was among the key messages delivered by Ioli Christopoulou at the event "Cohesion Policy 2028–2034 | National and Regional Partnership Plan", organised by the General Secretariat for the Partnership Agreement (NSRF) of the Ministry of National Economy and Finance on 9 July 2026 at the Athens Conservatoire (Odeon of Athens).
New policy recommendations for restoring Posidonia meadows in Greece and across the Mediterranean
As EU Member States prepare their National Restoration Plans under the EU Nature Restoration Regulation and engage in negotiations on the priorities of the 2028–2034 Multiannual Financial Framework, a new report from the Interreg Euro-MED ARTEMIS project highlights what is needed to move from the legal protection of Posidonia meadows to the systematic implementation of restoration actions at national and Mediterranean scale.
Trends in fossil gas consumption & imports – June 2026
In the first six months of 2026, domestic gas consumption reached 34.4 TWh, down slightly from the all-time high set in 2025. LNG ranked first in imports for the six-month period and reached a record high (22.07 TWh), while imports via Sidirokastro continue as usual, though the majority are re-exported (7.35 TWh, 47.5% of the six-month total).
The carbon footprint of electricity production – May 2026
The carbon intensity of electricity generation reached a historic low in May 2026 (200 g CO2/kWh), as it also did for 2026 as a whole (227 g CO2/kWh), thanks to record-breaking generation from renewables and hydropower during the first five months. Without the significant curtailments of renewables during this period (1.3 TWh), the average carbon intensity would have been 14.2% lower and below 200 g CO2/kWh. The Agios Dimitrios lignite-fired power plant emitted 0.11 million metric tons during its final month of operation and 1.58 million metric tons over the five-month period, remaining the top polluter.
