Multiple Benefits of Energy Efficiency for Business
Energy efficiency is often described as the “first fuel” because the cheapest and most secure energy is the energy that is not used. For businesses, this begins with a straightforward benefit: lower energy bills. In many cases, efficiency investments can pay back quickly through reduced energy costs alone. However, the value of energy efficiency extends beyond energy savings.This report builds on the IEA’s work on the multiple benefits of energy efficiency and focusses on how these gains materialise in businesses. Key benefits range from productivity and product quality improvements to brand image or health benefits for employees and…

Global Methane Tracker 2026
…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 edition includes a chapter on the efforts among numerous countries to develop marketplaces for fuels with near-zero methane intensity. It is accompanied by a template framework to help countries respond to satellite-detected large-emissions events, as well…

Energy Transition Review for Enhancing Co-operation
The Philippines’ power sector This report is part of ongoing IEA collaboration with Asia Zero Emission Community (AZEC) partners to better understand the particular challenges these partners face in their energy transition and to provide a platform for co-operation among the AZEC partners. The report seeks to build a shared understanding of the challenges and opportunities facing the Philippine power sector, and to identify practical pathways that can help to strengthen its energy security, improve affordability and enable the country to achieve its long-term clean energy goals.This review has been prepared in collaboration with the Department of Energy…

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…

Global Hydrogen Review 2025
Global Hydrogen Review 2025 The Global Hydrogen Review is an annual publication by the International Energy Agency that tracks hydrogen production and demand worldwide, shedding light on the latest developments on policy, infrastructure, trade, investments and innovation. The report is an output of the Clean Energy Ministerial Hydrogen Initiative and is intended to provide an update to energy sector stakeholders on the status and future prospects of hydrogen, and to inform discussions at the Hydrogen Energy Ministerial Meeting organised by Japan.The sector has progressed significantly since the first publication of the Global Hydrogen Review in 2021. Low-emissions hydrogen…

Sustainable Transport for Georgia: A Roadmap
The International Energy Agency (IEA) developed this Sustainable Transport Policy for Georgia roadmap under the European Union-funded five-year EU4Energy programme, which supports evidence-based energy policy and data capabilities in Eastern Partnership countries, including Georgia.The roadmap supports sustainable transport planning at national and city levels, summarising legislation, planning documents, and research on passenger and freight transport. Key metrics include accessibility, safety, convenience, equity, energy efficiency, emissions reduction, congestion and service reliability. Policies and targets are proposed to help Georgia meet the United Nations’ Sustainable Development Goals and achieve its Nationally Determined Contribution (NDC) pledges.The government of…

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…

Financing the ASEAN Power Grid
The Association of Southeast Asian Nations (ASEAN) has a long history of electricity system connectivity, and the development of the ASEAN Power Grid (APG) is central to achieving a sustainable, secure and affordable energy transition across the region. Delivering the APG will require a significant step‑change in investment over the coming 15 years, and unlocking financing from a diverse range of sources will be essential for this to happen. Yet financing approaches and business models have not evolved at the pace required to support an increasingly ambitious and complex pipeline of interconnector projects.This report examines how interconnectors are approached…

India Bioenergy Market Report
Outlook for liquid and gaseous biofuels to 2030 As demand for renewable energy grows in India, liquid and gaseous biofuels are expected to be one of the fastest-growing markets, driven by significant feedstock potential and supportive policies. These fuels can provide low-emission energy in heat, electricity and transport. They can also be produced domestically reducing reliance on imported fossil fuels, improve energy security, and create economic development and employment opportunities.This report examines the current supply and demand of liquid and gaseous biofuels in India and their forecasted growth to 2030. It provides a detailed assessment of existing…

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…
