Technology Explainer: Europe’s heatwaves are testing nuclear plants. What does it mean for nuclear energy in a warming climate?
Recent European heatwaves have forced nuclear plants in France, Romania, and Hungary to reduce output or shut down due to high river temperatures and low water levels, which trigger environmental protections for aquatic ecosystems. While these disruptions are environmental operating constraints rather than safety failures, they highlight the need for climate-resilient design. Adaptation options include transitioning to indirect or dry cooling systems, utilizing deeper seawater for coastal plants, and deploying advanced reactors or small modular reactors that require less water. The document emphasizes that these challenges are shared by other thermal power plants and that future energy planning must incorporate projected climate conditions into siting and design.

The ECB’s choice: shield the energy transition or repeat past mistakes
The author contends that raising interest rates to curb inflation caused by the war on Iran would disproportionately hinder renewable energy investments compared to fossil fuels, thereby prolonging Europe's energy vulnerability. To maintain price stability and support the energy transition, the document proposes that the ECB introduce 'Green TLTROs'—Targeted Longer Term Refinancing Operations—to provide lower interest rates for lending dedicated to renewable deployment, electrification, and grid upgrades.

Türkiye Electricity Review 2026
In 2025, wind and solar energy reached a record 22% of Türkiye's electricity generation, though coal remained the largest source at 34%. While the country has a massive 33 GW battery project pipeline that exceeds any single EU nation, it still trails European averages for renewable energy share. Persistent drought has significantly reduced hydroelectric output, increasing reliance on natural gas imports by an estimated $1.8 billion annually. A new purchase guarantee for domestic coal plants starting in 2026 may further increase coal generation, potentially contradicting the country's 2035 target of 120 GW of wind and solar capacity.

Renegotiation of Australia’s Bilateral Investment Treaties
The International Institute for Sustainable Development (IISD) recommends that Australia move away from an outdated bilateral investment treaty (BIT) model that prioritizes investor protection and investor-state dispute settlement. Instead, IISD proposes a reimagined regime where treaties serve as tools for sustainable development, prioritizing investments in climate mitigation, adaptation, and a just transition, while ensuring national law remains the primary regulator.

Renegotiation of Australia’s Bilateral Investment Treaties
The International Institute for Sustainable Development (IISD) argues that Australia's older BITs are based on an outdated model that prioritizes investor protection and investor-state dispute settlement (ISDS) over public policy. The submission recommends reimagining these treaties as tools for sustainable development, prioritizing climate mitigation and a just transition. Key proposals include removing ISDS, implementing carve-outs for fossil fuel investments and climate measures, and reforming how damages are calculated to prevent exorbitant awards. IISD suggests that national legal frameworks, rather than international treaties, should be the primary regulators of foreign investment.

ICJ AO Litigation Notes Digest February 2026
The document analyzes the legal implications of the ICJ's 2025 advisory opinion for 'government framework cases,' which target emissions reduction targets and regulatory frameworks. It details how the ICJ clarified that 1.5°C is the primary temperature goal of the Paris Agreement and established a 'stringent' due diligence standard for States in preparing and implementing Nationally Determined Contributions (NDCs). The guide highlights that NDCs must reflect a State's 'highest possible ambition' and be capable of making an adequate contribution to the 1.5°C goal. It also emphasizes the application of customary international law regarding the duty to prevent significant transboundary harm and the duty to cooperate, regardless of treaty membership. Furthermore, the document connects climate action to human rights obligations and intergenerational equity, providing a legal basis for courts to order remedies such as the adoption of consistent NDCs or full reparation.

Plugging heat in: smart policy can help electrify household heating in Europe
The report argues that high electricity prices, often inflated by policy-related levies, make heat pumps less cost-competitive than gas boilers despite their superior efficiency. It analyzes various policy levers—such as removing levies, reducing VAT, or implementing innovative tariffs—to lower the electricity-to-gas price ratio, which the European Heat Pump Association suggests should be no higher than 2 for competitiveness. The analysis highlights that the Netherlands, with the lowest price ratio (1.4), has significantly higher heat pump sales than countries like Germany, Poland, or Hungary, where ratios exceed 3.
