Global Methane Tracker 2025
Methane is responsible for around 30% of the rise in global temperatures since the Industrial Revolution, and rapid and sustained reductions in methane emissions are key to limiting near-term global warming and improving air quality. The energy sector – including oil, natural gas, coal and bioenergy – accounts for more than 35% of methane emissions from human activity and has some of the best opportunities to cut these emissions. The annually updated Global Methane Tracker is an essential tool for raising awareness about methane emissions across the energy sector and the opportunities to bring them down.The Tracker presents our latest…

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…

Assessing emissions from LNG supply and abatement options
Drawing on the latest and best available data, this report provides a comprehensive estimate of greenhouse gas (GHG) emissions across the global liquefied natural gas (LNG) supply chain, including from upstream production, processing, and pipeline transmission to liquefaction, shipping, and regasification. It also discusses the significant emissions reductions that are technically feasible with today’s technologies including through methane abatement, electrification using low-emissions power, process efficiency improvements, and the elimination of routine flaring, as well as carbon capture, utilisation and storage (CCUS) for managing the naturally-occurring CO2 from LNG supply. Introduction Around 550 billion cubic metres (bcm) of natural…

Czechia 2025
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 Czechia and the IEA. It draws on the IEA’s extensive…

Renewables in District Energy
This report examines how renewables can play a larger role in district energy systems, helping to deliver cleaner, more secure and more efficient heating and cooling. District energy networks already supply heat to 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…

Jobs
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores jobs. Why is energy efficiency important for jobs? Investment in energy efficiency creates jobs in a wide range of occupations and geographic locations. Key facts Around 10 million people work in energy efficiency-related jobs globally, representing nearly 15% of all energy-related jobs. Studies indicate that energy efficiency creates between 4 and 22 jobs per USD 1 million invested, depending on economic structure and energy efficiency measure. By lowering energy spending, energy efficiency also helps foster business growth and competitiveness. Energy efficiency offers a wide array of job opportunities…

Global Energy and Climate Model
Scenario analysis of future energy trends Global Energy and Climate Model Over the past four years, the IEA has worked to develop a new integrated modelling framework: the IEA’s Global Energy and Climate (GEC) Model. This model is now the principal tool used to generate detailed sector-by-sector and region-by-region long-term scenarios across IEA's publications, including the World Energy Outlook series and Energy Technology Perspectives series.In 2021, the IEA adopted for the first time a new hybrid modelling approach relying on the strengths of both models. The integrated framework of the IEA’s Global…

Vehicle-to-grid technology
GEVO 2026 - Chapter 8 With the rollout of smart and bidirectional charging, EV owners can reduce charging costs and, in some cases, generate revenue by participating in grid services, such as frequency regulation. Load shifting and vehicle‑to‑grid (V2G) capabilities provide substantial electricity system benefits, helping reduce peak demand and potentially limiting the need for future grid investment – benefits for which EV owners can be compensated. Vehicle-to-grid charging holds the promise of alleviating grid constraints but barriers remain The rollout of EVs is a major driver of global electricity demand growth. Residential EV charging can draw more power than…
