Delivering Sustainable Fuels
…enhance energy security, strengthen environmental sustainability and stimulate economic development, particularly in rural areas.If fully legislated and implemented, current and proposed national and international policies would put the use of sustainable liquid and gaseous fuels on a path to nearly double from 2024 levels by 2030 and quadruple by 2035. Progress must occur on multiple fronts to increase uptake and foster a large and diverse set of sustainable fuel pathways. This calls for a shared global vision for sustainable fuels, along with targeted policies to bridge costs gaps with conventional fuels, innovation to expand production potential, robust and mutually…

Global Hydrogen Review 2025
…significantly since the first publication of the Global Hydrogen Review in 2021. Low-emissions hydrogen production projects have gone from just a handful of demonstrations to more than 200 committed investments for projects that are increasing in number and in scale, reflecting the importance of hydrogen for climate goals, energy security and industrial competitiveness. Nevertheless, growth has not met all of the expectations raised at the start of the decade and remains uneven. Uncertainties about costs, infrastructure readiness and evolving regulatory frameworks all present barriers to faster deployment.This fifth edition of the Global Hydrogen Review takes stock of the…

Best Practices and Insights to Expand Clean Energy Access and Adoption
…enabling infrastructure, and investment that support long-term behavioural change.This report examines how policies, public engagement and sectoral transformation can create conditions for sustainable lifestyles that follow low-emissions practices and are resilient and inclusive. It draws on international evidence, including workshop discussions, IEA analysis and a wide range of global case studies, to identify key impacts and lessons learned from evidence and practice. It highlights how behaviour change is most effective when supported by coherent policy frameworks, targeted measures addressing affordability and structural changes across sectors such as buildings, transport and appliances. By identifying good practices and practical…

Autonomous vehicles
…and all commercial robotaxi services in operation today exclusively use EVs. High‑voltage batteries, reduced mechanical complexity, and precise torque control support the integration of automation systems with BEVs. ADAS and autonomous systems rely on extensive data collection and continuous software refinement – an area where digital-first architectures, pioneered by EV makers, provide a clear edge. The mutually reinforcing trends of software‑defined vehicles and automated driving are therefore consolidating the technological leadership of EVs. Partially automated driving is becoming mainstream while autonomous vehicles are starting to gain traction Over the past 10 years, ADAS have become much more widespread. In 2025…

Sustainable Transport for Georgia: A Roadmap
…infrastructure and operations, the report first examines the country as a whole, followed by Georgia’s largest cities. With road vehicles responsible for more than 98% of domestic transport energy use and carbon dioxide (CO₂) emissions, the focus is on road transport.Opportunities identified include improving vehicle efficiency – particularly by accelerating electric vehicle (EV) adoption – and cutting reliance on inefficient vehicles by reducing unnecessary car travel and shifting to buses, metro, walking and cycling, as well as intercity passenger and freight rail. These opportunities are presented as a coordinated and sequenced portfolio of policies designed to enhance transport efficiency and…

Efficient Grid-Interactive Buildings in India
Status and opportunities This report assesses the opportunities for efficient grid-interactive buildings (EGIBs) to support India’s clean energy transition. EGIBs unite energy efficiency, smart digital technologies and demand-side flexibility, allowing them to optimise energy use, shift or reduce peak demand and better align consumption with renewable energy generation.The buildings sector is central to clean energy transitions in a context where rapidly increasing electricity demand is driven by cooling and appliance use, and the share of variable renewable energy in electricity generation is continuously growing. Without targeted action, unmanaged peak loads and variable supply could jeopardise grid…

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…

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…

IEA Support to Accelerating Renewable Energy Permitting (ARPE)
Between October 2023 and March 2025, the IEA implemented the “Accelerating Renewable Energy Permitting” (ARPE) action. The goal of ARPE was to support five EU Member states – Finland, Ireland, Lithuania, the Netherlands, and the Slovak Republic (Focus countries) – in developing and implementing policy and regulatory measures aimed at reaching their renewable energy targets, notably through accelerating permitting of renewable energy projects.In support of this objective, the IEA organised and facilitated five workshops focused on the following topics:streamlining administrative proceduresaccelerating offshore wind deploymentfacilitating spatial planning for renewable energy deploymentensuring public engagement and acceptance, and afinal workshop summarizing the project…

Carbon-Free Electricity in G20 Countries
Status and the way forward In 2024, the Republic of Korea proposed the Carbon-Free Energy (CFE) Initiative to promote the use of technology-neutral, carbon-free energy to decarbonise the energy sector.In line with this initiative, Korea’s Ministry of Trade, Industry and Energy (MOTIE) commissioned this report to analyse the status and prospects of carbon-free energy in the electricity sector in G20 countries, and to provide policy recommendations to advance its progress.The International Energy Agency (IEA) and the Korea Energy Economics Institute (KEEi) jointly produced this report.
