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.

This report analyzes the emerging role of grid-scale batteries in the European Union as of 2025, highlighting their ability to compete with expensive gas-fired power during peak demand hours and reduce the curtailment of renewable energy. Using Italy as a primary example and California as a comparative case study, the document details how falling battery costs and widening price spreads are driving a record project pipeline aimed at lowering wholesale electricity prices and reducing reliance on 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.

The European Electricity Review 2026 by Ember analyzes electricity generation and demand across the EU-27 for 2025. The report highlights a historic tipping point where wind and solar combined to produce more electricity than all fossil fuel sources for the first time, while coal reached a new historic low. Despite this progress, the EU remains dependent on imported gas, which drove up electricity prices and import costs in 2025. The report emphasizes the role of battery storage in reducing gas reliance and curtailment of clean power.

This briefing by Zero Carbon Analytics examines how climate change is reducing the quantity and quality of sparkling wine globally. It details the impact of extreme weather on yields and pricing in key regions like France, Spain, and Italy, the chemical changes in grapes that alter flavor profiles, and the risks to agricultural workers. The document also discusses the limitations and costs of adaptation measures, noting that traditional wine-growing regions face a high risk of becoming unsuitable if global temperatures rise by 2°C or more.

This report by Ember analyzes how electricity pricing structures in the European Union act as a barrier to the adoption of heat pumps. It argues that while heat pumps are significantly more efficient than gas boilers, high electricity prices—often inflated by policy-related levies—make them less cost-competitive. The report evaluates various policy interventions, such as removing levies or shifting them to gas, to lower the electricity-to-gas price ratio and accelerate the electrification of household heating to meet REPowerEU 2030 goals.

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 research paper examines Nigeria's natural gas sector and its potential to drive sustainable industrialization across Africa. It analyzes the 'Decade of Gas' (2021-2030) initiative, critical infrastructure projects, and the regulatory reforms needed to transition from a reliance on oil exports to a gas-powered economy that supports regional energy security and manufacturing.

This research paper examines the role of green technology, specifically solar photovoltaic (PV) and onshore wind energy, in decarbonisation and industrialisation. It argues that market forces alone are insufficient for scaling renewable energy and emphasizes the necessity of targeted industrial policy and government intervention to ensure equitable transitions, particularly in developing economies like South Africa and Brazil.

A briefing by Zero Carbon Analytics detailing how soy-driven deforestation in Brazil's Cerrado biome reduces regional rainfall and agricultural productivity, creating a paradox where individual farmer profits are outweighed by regional economic losses and global supply chain risks.

This report by RMI examines the decarbonization of the cement and concrete sector, which contributes nearly 8 percent of global carbon dioxide emissions. It outlines a strategic framework for innovation categorized as "Make Less," "Make Better," and "Make New," while highlighting the funding gap and the necessity of updating prescriptive industry standards to performance-based specifications to accelerate the adoption of low-carbon materials.

This briefing by Zero Carbon Analytics explores how decarbonisation can provide a competitive advantage for Polish businesses by reducing energy costs, improving productivity, and appealing to climate-conscious consumers. It highlights the financial risks associated with Poland's high-carbon energy mix, specifically the costs of the EU Emissions Trading System (ETS), and suggests that transitioning to renewables and energy efficiency can enhance national GDP and corporate profitability.

Plan 1.5 criticizes the South Korean government's 2035 Nationally Determined Contribution (NDC) for setting a lower bound that fails to meet constitutional and international legal responsibilities for the 1.5°C climate goal.

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.
