Most climate surveys ask whether you are worried. We already know the answer. We are asking something harder: where climate action should focus in the coming years, who is left out of the programmes running today, and which issues never make it to the funding table. Ten multiple-choice questions, under five minutes. The questionnaire was reviewed by our Advisory Board before launch. The answers will feed into our planning and the proposals we are preparing, and we will publish the findings.

Read the article →Greece has the EU's longest coastline, and it's disappearing
Nearly 10% of the Greek coastline studied is eroding by more than 3m a year, costing an estimated €2.6B annually. Sea level rise, sand mining, dams and coastal infrastructure are to blame, and policy has gone backwards.

Posidonia oceanica absorbs CO₂ 15x faster than the Amazon and is unique to the Mediterranean. We've lost up to half of it in 50 years, and unlike France, Spain and Croatia, Greece still has no anchoring ban.

Entry to Europe's top 20 climate tech hubs takes ~$55–100M a year and 10+ deals. With €376M raised by new Athens-based funds in the past year, we think Athens can get there.

Tourism makes up 28–34% of Greece's GDP, but in the most popular destinations water, energy, waste and housing systems run far beyond capacity each summer. At what point does it start to undermine itself?

Greece wastes about 1 in 8 units of clean power it produces. The startups tackling curtailment, idle batteries and permitting delays, from Optimus Energy and Sympower to Energy Dome's lithium-free storage.
Read the article →Good policy doesn't build megawatts
Greece has passed the energy laws. Now come the second-order gaps: shallow battery markets, invisible grid data, no industrial demand plan, no V2G rules and no single owner of delivery. Each already solved in Europe.

US-based RDI Irrigation's GrowStream tube releases water only when plant roots signal thirst, claiming up to 50% less water than conventional drip. Why that matters for Greece, where ~85% of water goes to farming.

Eleven structural bottlenecks, from grid curtailment and missing batteries to gas-set prices, Russian gas, slow EV charging and permitting backlogs, are keeping Greek bills high and slowing the transition.

Greek olive oil output fell to ~120,000 tonnes in 2023/24 and is still well below 2022/23 levels. Drought, heat and extreme weather are converging, and farmers say they lack the tools to adapt.
Read the article →Greece is generating more clean energy than ever
If clean energy is cheap, why are Greek electricity bills still 46% higher than 2019? Marginal pricing, Contracts for Difference that only start in 2027, and windfalls for existing generators explain why.
