Global Critical Minerals Outlook 2025
Critical minerals, which are essential for a range of energy technologies and for the broader economy, have become a major focus in global policy and trade discussions. Price volatility, supply chain bottlenecks and geopolitical concerns make the regular monitoring of their supply and demand extremely vital.The Global Critical Minerals Outlook 2025 includes a detailed assessment of the latest market and investment trends, along with their implications for critical minerals security. As in last year’s Outlook, it provides a snapshot of recent industry developments from 2024 and early 2025 and offers medium- and long-term projections for the supply and demand of key…

Grid investments
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores grid investments. Why is energy efficiency important for grid investments? As we enter the Age of Electricity, global electricity demand is rising rapidly – and so is the demand for the expansion of electricity grids. Energy efficiency can help close the gap between supply and demand, but often at a lower cost, and more quickly, than new generation and grid expansion. Key facts On average, energy efficiency costs less than half the amount it would cost to build new generation capacity and grid infrastructure, per unit of…

Lithium
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.

Cost of Capital Observatory
Tracking the cost of capital for clean energy projects in emerging and developing economies The Cost of Capital Observatory is an initiative from the IEA, the World Economic Forum, ETH Zurich and Imperial College London. The aim of the Observatory is to increase transparency in the energy sector and inspire investor confidence, especially in emerging and developing countries where data on financing costs is scarcer.The Observatory is divided into three sections:A Dashboard that provides free data on the cost of capital for energy projects in emerging and developing economies, updated with 2023 and 2024 data in July and…

Demand and Supply Measures for the Steel and Cement Transition
The case for international co-ordination A massive scale-up of markets for transformative near-zero emissions steel and cement is needed to achieve internationally agreed net zero goals. Yet early movers on both the supply- and demand-side – that is, material producers and consumers – face substantial barriers related to high costs and risks, among other factors. This has led to relatively slow market growth for near-zero emissions materials, at a moment when reinvesting in long-lived high-emissions production could have repercussions for governments to achieve their stated climate goals. Policy makers have the opportunity to play a…

Outlook for Biogas and Biomethane
A global geospatial assessment Biogases play an important and growing role in energy systems. Produced locally using organic waste, biogas and biomethane can contribute to energy security, waste management, emissions reductions and agricultural development.In recent years, demand for biomethane – also known as “renewable natural gas” – has grown rapidly in many countries, supported by dozens of new policies. As a low-emissions substitute for natural gas, the use of biomethane has been targeted across a wide range of sectors, including power, industry, transport and buildings. This report presents a first-of-its-kind global geographical analysis of the untapped potential…

Luxembourg 2026
Energy Policy Review Government action plays a pivotal role in ensuring secure and sustainable energy transitions. Energy policy is critical not just for the energy sector but also for meeting environmental, economic and social goals. Governments need to respond to their country’s specific needs, adapt to regional contexts and help address global challenges. In this context, the International Energy Agency (IEA) conducts Energy Policy Reviews to support governments in developing more impactful energy and climate policies.This Energy Policy Review was prepared in partnership between the Government of Luxembourg and the IEA. It draws on the IEA’s extensive…

Rare Earth Elements
Pathways to secure and diversified supply chains The critical role of rare earth elements in strategic applications, ranging from energy technologies and advanced electronics to aerospace and defence systems, combined with their highly concentrated supply chains, has elevated their importance in both energy and broader economic security discussions in recent years. This report assesses the current state of the rare earth elements market, examining demand and supply dynamics and key technological developments. It analyses the full value chain from mining to permanent magnet production, evaluates vulnerabilities across supply chains, and highlights the implications of potential supply disruptions. Based on these…

Prospects for Natural Gas Certification
This report offers an overview of the role of certification in natural gas supply chains, provides a broad mapping of existing initiatives, highlights selected regulatory and market developments, identifies areas where improvements may be needed, and presents recommendations to support the development of credible certification frameworks.Certified natural gas refers to gas whose environmental and social attributes – such as greenhouse gas (GHG) emissions performance, water use, local community impacts and worker safety – have been independently verified against defined criteria or benchmarks. In 2024, around 7.5% of global natural gas production was certified, with volumes primarily originating from North America…

Energy Efficiency Policy Toolkit
The Energy Efficiency Policy Toolkit is an interactive online tool that has been updated and expanded ahead of the 11th Annual Global Conference on Energy Efficiency in Montreal, Canada. It aims to support governments in designing and implementing effective energy efficiency measures by combining policies across three core pillars: regulation, information and incentives. It also features a wide range of case studies, offering practical insights into the successful implementation of energy efficiency policies across diverse national and sectoral contexts.The Toolkit builds on earlier IEA work to advance energy efficiency policy. In 2022, the IEA introduced Policy Packages for Energy…
