World Energy Outlook 2025
The IEA’s flagship World Energy Outlook (WEO) is the most authoritative source of global energy analysis and projections. Updated annually to reflect the latest energy data, technology and market trends, and government policies, it explores a range of possible energy futures and their implications for energy security, access and emissions. The WEO covers the whole energy system, using a scenario-based approach to highlight the central choices, consequences and contingencies that lie ahead. It includes exploratory scenarios that flow from different assumptions about existing policies, as well as normative pathways that achieve energy and emissions goals in full. The multi…

Gas 2025
Analysis and forecasts to 2030 Global gas markets are set to undergo major changes by the end of the decade, with the coming wave of liquefied natural gas (LNG) production capacity set to profoundly transform market dynamics. The unprecedented scaling up of LNG supply is expected to improve gas supply security and make natural gas more affordable – including in emerging, price-sensitive import markets. However, to account for these shifts, LNG producers and suppliers may need to adapt their medium-term strategies.The Gas 2025 medium-term report from the International Energy Agency (IEA) examines this coming transformation and its…

Asset values
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores asset values. Why is energy efficiency important for asset values? Energy efficiency can increase the value of assets, such as homes, buildings or equipment, and lead to lower vacancy rates and longer equipment lifespans. Key facts Energy efficient buildings can command a premium on sale and rental price in both the residential and commercial sectors. Studies show that sale price premiums for energy efficient buildings range from 3% to 15% in residential buildings and 13 to 20% in commercial buildings. Key analysis Studies show that individuals…

Pledges to Progress 2025
An assessment of transparency of the oil and gas industry’s emissions reduction efforts At COP28, more than 50 of the world’s leading oil and gas companies launched the Oil and Gas Decarbonization Charter (OGDC), laying out a series of ambitions to achieve net zero operational emissions by 2050. As global methane and flaring emissions continue to rise, these ambitions are more important than ever to reduce energy waste and mitigate the harmful consequences of climate change.To support accountability and transparency, the International Energy Agency (IEA), the United Nations Environment Programme (UNEP) International Methane Emissions Observatory (IMEO) and…

Financing CCUS at Scale
How to Mobilise Private Capital Carbon capture, utilisation and storage (CCUS) is an important area of attention for governments and financiers as both look to balance policy and investment goals. Recent financial investment decisions of major projects show promise in a sector that is gaining momentum, but its future success depends on viable business models and effective risk allocation across the value chain.In this context, Financing CCUS at Scale is the IEA’s latest report on what it takes to move CCUS projects from the drawing board to operation. Building on expert interviews with leading financial institutions, the report…

Overview graphic: key technology trends for EVs
GEVO 2026 - Chapter 8 Electric vehicles (EVs) are increasingly at the centre of innovation in the automotive sector, bringing advances that extend far beyond developments in batteries and power electronics, thanks to several mutually reinforcing factors. Key technology trends are aligning in favour of EVs Battery electric vehicles (BEVs) are mechanically simpler than internal combustion engine vehicles (ICEVs) or hybrids, making them more compatible with digitalisation and automation. The relative simplicity of electric drivetrains enables shorter development cycles for new vehicles, allowing emerging technologies to reach BEVs sooner than vehicles with other powertrains.While the transition from mechanical to software…

Emission reductions
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores emission reductions. Why is energy efficiency important for emission reductions? Energy efficiency can reduce emissions of greenhouse gases and air pollutants and make the energy system more sustainable. Key facts Since 2010, efficiency measures avoided energy-related carbon dioxide (CO₂) emissions equivalent to nearly 20% of the global total in 2023. This is more than the entire energy-related emissions of India and the European Union combined. Accelerating efficiency improvements could deliver a third of all energy-related CO₂ emission reductions between now and 2030 in…

Artificial intelligence and EVs
GEVO 2026 - Chapter 8 Progress in AI and computing power is disproportionately benefiting EVs, particularly for automated driving and integrated vehicle control. Sensors and chips integrate well with the stable, high-voltage power supply of EV batteries. At the same time, the benefits of AI and increased computing power are not exclusive to EVs. AI‑enabled energy management systems are increasingly used to optimise hybrid vehicles, and AI techniques are accelerating the design, testing and optimisation of all vehicles. Advances in AI underpin progress in autonomous vehicles Just two decades ago, state-of-the-art autonomous vehicles were confined to test…

Responding to Satellite Notifications from the Methane Alert and Response System
In 2023, the International Methane Emissions Observatory launched the Methane Alert and Response System, the first global system to provide free satellite-based alerts on major emission events to governments. Prompt reaction to MARS notifications has led to the successful mitigation of methane leaks in several countries. However, the global response rate to MARS notifications remains relatively low, suggesting that further measures may be required to transform satellite alerts into actionable responses for governments.The IEA, in collaboration with IMEO, has prepared this technical guidance document to assist governments seeking to improve action on MARS notifications and reduce methane emissions…

National Climate Resilience Assessment for Mozambique
Mozambique’s energy system has experienced significant disruptions due to extreme weather events, notably tropical storms and cyclones. With climate change, storms are projected to intensify, as are the risks of seasonal droughts and floods, posing a threat to the reliable operation of hydropower generation and the secure operation of the country’s coal mines. Mozambique’s plans to diversify its energy supply are an important step to enhance energy security and could be complemented by targeted measures to make its electricity system more resilient to natural hazards. Storms and tropical cyclones present the most regular extreme weather event faced…
