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…

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…

Competitiveness
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores competitiveness. Why is energy efficiency important for competitiveness? Increasing energy efficiency can improve competitiveness at both the firm level – by reducing costs, improving operations and increasing product value – and at the country level, by reducing the amount of energy required to produce economic output. Key facts Today the world’s industries produce nearly 20% more value added with a given amount of energy, compared with two decades ago. In the industrial sector, energy management can lead to more than 10% in annual energy cost savings within…

National Climate Resilience Assessment for Algeria
Algeria’s energy system already faces significant disruption due to extreme weather events. Critical infrastructure has been impacted in recent years by flash floods, drought-induced wildfires and heatwaves. With the climate projected to warm more rapidly than the global average, these risks are likely to intensify. Proactive measures to enhance the resilience of Algeria’s energy system could offer substantial benefits.Algeria has experienced significant warming, averaging 0.49 °C per decade from 2000 to 2023 and exceeding the global average of 0.37 °C per decade. Temperatures are expected to rise further, reaching up to 5.6 °C above pre‑industrial levels…

Gas Market Lessons from the 2022-2023 Energy Crisis
The 2022-2023 energy crisis tested the resilience of the global gas and LNG markets with the most severe gas supply shock in history. During the crisis, natural gas-importing markets around the world felt the pressures of record-high gas prices, including the scale-back in access to energy, the impediment to economic activity and the extra burden on government budgets. Market responses varied but governments were quick to react as the challenges of security of supply became apparent. Post-crisis, markets must continue to adapt as the effects of the crisis continue to influence security of gas supply…

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…

Energy security
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores energy security. Why is energy efficiency important for energy security? Energy efficiency can help mitigate energy security risks by reducing the reliance on fossil fuel imports, improving grid reliability, and acting as a buffer to supply shocks. Key facts Efficiency gains from the last two decades avoided the need for 20% more fossil fuel imports in IEA countries. Energy efficiency and demand response can support grid reliability by reducing peak demand. For instance, more efficient air conditioners in India could lower the impact of heatwaves on…

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…

Sustainable Transport Policy for Armenia: A Roadmap
As a part of the EU4Energy Programme, the Armenia Energy Policy Roadmap on Sustainable Transport presents a comprehensive, evidence-based framework for transforming the country’s mobility system into a sustainable and efficient transport system. The strategy seeks to deliver significant reductions in CO₂ emissions while strengthening regional connectivity, fostering economic development, and enhancing energy security. While Armenia has made notable progress in rolling out electric vehicles and electrifying its rail network, it still struggles with a high dependence on imported fossil fuels, a lack of data transparency and weak co-ordination among government agencies. This roadmap is structured to…

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…
