A new analysis by The Green Tank, titled “Vertical Corridor: Gas Demand and Economic Viability,” examines whether existing and planned LNG infrastructure in Greece is needed to meet future fossil gas demand in the region through 2040. It also assesses the economic competitiveness of gas transit via the Vertical Corridor compared with routes from other entry points to Ukraine and Hungary.

Recent commentary has suggested that Greece exports surplus renewable electricity to Bulgaria during the middle of the day, when solar PV output peaks and wholesale electricity prices are low, only for Bulgaria to store part of this electricity and sell it back to Greece at a higher price after sunset. While this narrative has gained traction, analysis of the available...

Energy communities and self-generation are the main tools enabling citizens, local communities, and small businesses to actively participate in the energy transition. However, the latest data point to a continuing slowdown, both in the development of new projects and in the implementation of existing applications. The Green Tank’s 9th review of energy communities and self-generation in Greece analyses the latest available data from HEDNO, IPTO and GEMI, highlighting the most important trends.

The cement industry is one of the most carbon-intensive industrial sectors globally. Yet its decarbonization is accompanied by significant technical and economic challenges. With the window for achieving the EU’s binding 2030 climate targets rapidly narrowing and the gradual phase-out of free allowances under the EU Emissions Trading System (EU ETS) affecting the sector’s competitiveness, closing the investment gap for decarbonization projects has become an urgent priority.

In 2025, Greece had the highest retail electricity prices in the EU-27 in terms of consumers’ purchasing power and the third highest in nominal prices. At the same time, the more expensive green tariffs continued to dominate the market despite their high cost, while increased fossil gas use kept both wholesale and retail electricity prices at elevated levels.

Emissions from the four sectors covered by the EU Emissions Trading System (EU ETS) in the EU-27 remained largely unchanged in 2025 (-1.7%). At the same time, lignite and hard coal continued to account for 46% of emissions in the power and heat sector. In Greece, emissions from this sector increased due to higher fossil gas use, while the country recorded the highest maritime emissions in the EU. By contrast, the carbon footprint of the Greek cement industry fell by 9.2%, and that of refineries by 4.6%.
