Renewables in District Energy
…around 600 million people worldwide, but many systems remain heavily dependent on fossil fuels, exposing consumers and utilities to price volatility, supply risks and high emissions.The report provides a global overview of district energy systems, their fuel mixes, market conditions, governance models and affordability implications. It explores the growing opportunities offered by renewable and recovered heat sources, including bioenergy, geothermal, solar thermal, waste heat, large-scale heat pumps and thermal energy storage. It also sets out policy priorities for three types of markets: established systems with high renewable shares, fossil fuel-intensive networks, and emerging or untapped district energy markets.

Global Methane Tracker 2026
…near-term global warming, enhance energy security, and improve air quality. The energy sector – including oil, natural gas, coal and bioenergy – accounts for around 40% of methane emissions from human activity and has some of the best opportunities to cut these emissions. The annually updated Global Methane Tracker provides essential data on methane emissions across the energy sector and the opportunities to bring them down.The Tracker presents the IEA’s latest sector-wide emissions estimates – based on the most recent data from satellites and measurement campaigns – and discusses different abatement options along with their associated costs. This year's…

Rare earth elements 2025
Outlook for key energy transition minerals This report provides an outlook for demand and supply for key energy minerals including copper, lithium, nickel, cobalt, graphite and rare earth elements. Demand projections encompass both key energy technologies and other uses under different IEA Scenarios. Supply projections are based on a detailed review of all announced projects. They show how today's geographical concentration evolves over time, for both mining and refining and how expected supply compares with primary supply requirements.

Financing the ASEAN Power Grid
…how these assets are financed in practice and what must change to make them bankable for a wide set of potential investors.By quantifying total investment needs and potential sources of finance, identifying key barriers and offering clear, actionable recommendations, this report aims to equip policy makers, regulators, utilities, financiers and private‑sector stakeholders with the guidance needed to accelerate the financing and implementation of the ASEAN Power Grid. This analysis has been supported by the Clean Energy Transitions Programme, the IEA’s flagship initiative to transform the world’s energy system to achieve a secure and sustainable future for all.

Scaling Up Transition Finance
…While vital, these investments alone cannot deliver all the changes needed to cut global emissions, especially in areas where clean technologies are not yet commercially available or cost-competitive. This is where transition finance comes in: it can help emissions-intensive countries, companies and sectors shift over time towards sustainable practices that are aligned with long-term climate and development goals.In this new report, the International Energy Agency (IEA) provides analyses to map the landscape for transition finance, explains why it matters, and highlights approaches that could move the debate forward.The report also examines the role of transition…

Financing the Modernisation of Power Systems Beyond Coal
…emissions from operating plants, and considers the investment and power system planning challenges of replacing coal generation while maintaining essential system services. It also reviews project‑based and emerging jurisdictional approaches to transition credits, focusing on methodologies for the early retirement of grid‑connected coal plants and their replacement with clean energy.By examining these issues from a power system, investment and carbon markets perspective, the report aims to provide a clearer understanding of coal transition strategies and outlines recommendations for countries that may choose to explore transition credits as an option to reduce the role of coal in their electricity mix.
