The report 'Crossed wires: Grid capacity could block EU energy security' by Ember analyzes how limited grid capacity in Europe threatens energy security and economic competitiveness. It identifies significant shortfalls in grid hosting capacity for both new renewable energy projects and industrial demand, while noting that distribution grids are generally better prepared for household electrification, with notable exceptions in Spain and Poland.

The April 2026 Peace & Security Council Report examines key African Union (AU) initiatives, including a UN resolution on slavery reparations, the integration of governance intelligence into security actions via the APRM-PSC interface, the precarious stability of South Sudan ahead of 2026 elections, and a review of Angola's tenure as AU chair.

This research paper examines how slavery, imperialism, and colonialism fundamentally altered African agriculture by depleting the productive labour force, displacing indigenous crops with export commodities, and establishing land tenure systems that favoured European settlers and firms.

This report by the Environmental and Energy Study Institute examines reconductoring—the process of replacing existing electrical transmission cables with advanced conductors—as a rapid and cost-effective method to increase the capacity of the U.S. energy grid. The author argues that reconductoring can bypass lengthy permitting processes, reduce energy costs, and support the transition to clean energy by enabling the connection of stalled renewable projects and meeting rising electricity demands from electric vehicles and data centers.

This briefing by Ember analyzes the impact of a March 2026 energy shock caused by conflict in the Middle East, which led to spikes in European gas prices and increased fossil import costs. The document highlights how varying levels of reliance on gas for electricity generation across EU member states create disparate levels of exposure to price volatility, arguing that reducing gas dependency is the only effective way to build resilience against such shocks.

This report by Ember analyzes the impact of a March 2026 escalation of conflict in the Middle East on European energy prices. It highlights how the resulting spike in gas prices increased the EU's fossil import bill and electricity costs, while demonstrating that countries with lower reliance on gas-fired power, such as Spain, are more resilient to such shocks.

This report by Ember analyzes the evolving potential of geothermal electricity in Europe, highlighting how technological advances in drilling and reservoir engineering are making geothermal a cost-competitive, firm, low-carbon alternative to fossil fuels. It emphasizes that while Europe pioneered many of these technologies, it now risks losing its leadership to the US and Canada due to a lack of coordinated EU-level policy and investment frameworks.

This guide, published by the Center for International Environmental Law (CIEL) in February 2026, provides structured 'Litigation Notes' to help lawyers integrate the findings of the International Court of Justice's (ICJ) July 23, 2025, Advisory Opinion (AO) on State obligations regarding climate change into current and future legal cases. The document breaks down the ICJ's conclusions into thematic areas, including government framework litigation, adaptation, remedies and reparations, the right to a healthy environment, corporate conduct, climate finance, speculative interventions, and regulatory backsliding. It aims to translate the ICJ's normative clarity into practical tools for promoting climate justice across national, regional, and international courts.

This guide provides a series of structured 'Litigation Notes' designed to help legal practitioners integrate the findings of the International Court of Justice's (ICJ) July 23, 2025, Advisory Opinion (AO) on States' obligations regarding climate change into domestic, regional, and international court cases. The document breaks down the ICJ AO by key themes—including government framework cases, adaptation, remedies and reparations, the right to a healthy environment, corporate conduct, climate financing, speculative interventions, and regulatory rollbacks—providing specific excerpts from the opinion and illustrating their application through existing and potential litigation categories.

This briefing note analyzes the implications of the International Court of Justice's (ICJ) July 2025 advisory opinion on States' obligations to prevent environmental harm, specifically focusing on the financing of climate-destructive conduct. It outlines how the ICJ's findings can be used in litigation to challenge public and private funding of the fossil fuel sector and to enforce obligations for climate finance in developing nations.

This litigation guide analyzes the 2025 ICJ Advisory Opinion to provide a legal framework for challenging 'regulatory rollbacks'—the weakening of climate and environmental protections. It highlights the ICJ's 'stringent due diligence' standard, the duty to prevent significant harm to the climate system, and the requirement for progressive NDCs aligned with a 1.5°C limit. The guide argues that rollbacks in emission standards, forest protections, and EIA procedures may constitute internationally wrongful acts, citing specific recent examples from India, Germany, Belgium, France, and the United States.

This briefing, published by the Center for International Environmental Law (CIEL) and partners, provides a structured 'Litigation Note' to help legal practitioners apply the International Court of Justice's (ICJ) July 23, 2025, advisory opinion (AO) on States' obligations regarding climate change. The document focuses specifically on the legal frameworks for remedies and reparations, detailing how the ICJ AO clarifies State responsibility for internationally wrongful acts related to climate harm and how these findings can be integrated into domestic, regional, and international litigation against both States and corporate actors.

This litigation note, published by the Center for International Environmental Law (CIEL) in February 2026, provides a guide for legal practitioners to integrate the International Court of Justice's (ICJ) July 23, 2025, advisory opinion (AO) on climate change into government framework litigation. It specifically focuses on 'Ambition Gap' and 'Implementation Gap' cases, detailing how the ICJ's findings on Nationally Determined Contributions (NDCs), due diligence, and human rights can be used to challenge insufficient government climate policies.

A report by Ember detailing the rapid growth of battery electric vehicle (BEV) sales in Türkiye, which became Europe's fourth-largest market for new BEVs in 2025, while noting that the overall vehicle fleet remains dominated by fossil fuels.

In 2025, the European Union's power sector reached a tipping point as wind and solar generation surpassed fossil fuels for the first time, accounting for 30.1% of electricity. While solar generation hit record highs and coal reached a historic low, gas power saw a slight increase, though it remained below pre-crisis levels.

This report by Ember assesses the current state and future requirements of Europe's electricity interconnection. It finds that the EU is not on track to meet its 2030 interconnection targets, with 80% of the power system expected to miss the goal. To reach an optimal grid by 2040, Europe needs to nearly double its interconnection capacity, adding 151 GW, which requires an estimated €150 billion in investment. The report identifies a €30 billion public funding gap in the proposed Connecting Europe Facility for Energy (CEF-E) budget for 2028-2034, suggesting that this gap must be filled by EU loans and private funding to ensure energy security and cost-effectiveness.

This policy brief by the International Institute for Sustainable Development (IISD) examines the 2024 reform of the European Union's public procurement framework. It argues that while green public procurement (GPP) is a powerful lever for the green transition—given that public procurement accounts for approximately 14% of EU GDP—its implementation is hindered by legal uncertainties, administrative burdens, and capacity gaps. The document advocates for the use of robust, third-party verified tools such as ecolabels and life-cycle costing to simplify GPP and recommends specific legal and structural reforms to the EU directives to foster their uptake.

In the first half of 2025, global solar and wind generation grew sufficiently to exceed total electricity demand growth, resulting in renewables overtaking coal in the global electricity mix for the first time. While global power sector CO2 emissions fell marginally by 0.2%, results varied by region, with emissions decreasing in China and India but increasing in the US and EU.
