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…

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…

7 certainties about energy for this age of uncertainty
ED commentary The energy sector, like many others, is contending with a blizzard of uncertainties, complicating the work of policymakers, business leaders and investors.Geopolitical twists and turns are straining long-established relationships and upending deeply held assumptions. The World Uncertainty Index, devised by economists from the IMF and Stanford University, has hit unprecedented levels in recent months.But in this time of flux, there are still some important trends that we can identify with some confidence. Here are seven that can help us keep our bearings: The world has entered the age of electricity Oil and gas will still…

Global Hydrogen Review 2025 Production highlights
Highlights Hydrogen production reached almost 100 Mt in 2024, but less than 1% was based on low-emissions hydrogen technologies. Based on announced projects, low-emissions hydrogen could reach 37 Mtpa by 2030, a reduction from the 49 Mtpa estimated in the Global Hydrogen Review 2024 (GHR-24).More projects are reaching final investment decision (FID), although the total production capacity reaching this stage in 2024 remained at the same level as in 2023. Persisting technical and regulatory barriers, financial obstacles and challenges in securing reliable offtake, in particular, continue to delay and occasionally completely stall project progress.Despite announced delays and cancellations…

Global Energy and Climate Model Accelerating Clean Cooking and Electricity Services Scenario (ACCESS)
Even as global energy demand continues to rise, billions of people in around 100 countries remain without access to basic modern energy services. Today nearly 2 billion people lack access to clean cooking and 730 million people lack access to electricity. Millions of households, businesses and public institutions such as clinics and schools operate without reliable modern energy. This limits productivity and hinders socioeconomic development. It also perpetuates the use of traditional biomass, with damaging consequences for health and the environment.The Accelerating Clean Cooking and Electricity Services Scenario (ACCESS) charts a path to achieve universal access to clean cooking and electricity based…

Energy and AI
Energy and AI The development and uptake of artificial intelligence (AI) has accelerated in recent years – elevating the question of what widespread deployment of the technology will mean for the energy sector. There is no AI without energy – specifically electricity for data centres. At the same time, AI could transform how the energy industry operates if it is adopted at scale. However, until now, policy makers and other stakeholders have often lacked the tools to analyse both sides of this issue due to a lack of comprehensive data. This report from the International Energy Agency (IEA) aims to fill this…

Global Energy Review 2026 Coal
Global coal demand in 2025 grew moderately, remaining near 2024 levels Global coal demand in 2025 grew modestly above 2024 levels, rising by only 0.4%, an increase of around 30 million tonnes (or 0.7 EJ). This growth, which was in line with IEA estimates, was significantly below the 1.4% increase seen in 2024 and marked the end of the post-Covid rebound, with global coal demand growth slowing each year since 2021.Coal use in power generation diverged from recent trends in several regions around the world. In the United States, strong coal use in the power…

Stepping Up the Value Chain in Africa Executive summary
Africa is endowed with vast energy resources – fossil fuels, but also solar, wind, hydro, and geothermal – and yet energy supply remains limited: Around 600 million people on the continent lack reliable access to electricity. This energy gap constrains economic growth and industrial potential, particularly in rural areas where agriculture remains the dominant sector in the economy. As African economies grow and urbanise, the demand for energy-intensive industries and infrastructure is rising. Strategic investments in sustainable industrialisation can create a virtuous cycle that expands energy access and drives productivity, which in turn can attract more investment.Market opportunities already exist. Globally…
