Global Energy Review 2025 CO2 Emissions
Energy sector carbon emissions reached a new record in 2024 Total energy-related CO2 emissions increased by 0.8% in 2024, hitting an all-time high of 37.8 Gt CO2. This rise contributed to record atmospheric CO2 concentrations of 422.5 ppm in 2024, around 3 ppm higher than 2023 and 50% higher than pre-industrial levels. In 2024, CO2 emissions from fuel combustion grew by around 1% or 357 Mt CO2, while emissions from industrial processes declined by 2.3% or 62 Mt CO2. Emissions growth was lower than global GDP growth (+3.2%), restoring the decades-long trend of decoupling emissions…

Electricity 2026 Emissions
CO2 emissions from electricity generation are forecast to plateau through 2030 In 2025, global emissions from electricity generation remained flat, after increasing 1.5% and 1.4% in in the previous two years, respectively. Even with strong gains in electricity demand, growth in power sector emissions is showing marked signs of slowing down as fossil-fired generation is constrained by the rapid deployment of renewables and rising nuclear power generation. As this trend continues, we forecast global emissions from power generation to plateau over our 2026-2030 outlook period due to significant increases in clean energy sources, despite electricity demand…

Coal 2025 Executive summary
Global coal demand in 2025 is set to remain close to 2024 levels amid unusual regional trends Key factors such as weather, fuel prices and policy decisions all shaped global coal consumption in 2025, driving changes in demand that often ran counter to recent country or regional trends.In India – one of the traditional engines of coal demand growth – an early and strong monsoon season depressed electricity demand and boosted hydropower output. As a result, the country’s annual coal power generation is set to decline year-on-year for only the third time in the past five decades. 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…

United Kingdom
The United Kingdom has been an early player in the energy transition, being among the first countries to set a net zero target by 2050 and to put in place carbon budgets. UK emissions have already fallen by around 50% since 1990, indicating a strong start. Looking ahead, an important pillar of the energy transition will be decarbonising the power sector through sizeable new investments in renewables and nuclear while also focusing on new technologies such as CCUS, hydrogen and small modular reactors. As a historic oil and gas producer, the UK is looking to address declining North Sea production…

Global Methane Tracker 2026 Key findings
No sign that global energy-related methane emissions fell in 2025 despite progress in some areas The fossil fuel sector accounts for around 35% of methane emissions from human activity, yet there is still no sign that methane emissions from fossil fuel operations are falling, despite well-known and proven mitigation pathways. Oil, gas and coal production output reached record highs in 2025, and the International Energy Agency (IEA) estimates that methane emissions from these activities total 124 million tonnes (Mt) a year: oil is the largest source at 45 Mt, followed by coal at 43 Mt, and natural gas at 36 Mt. A…

Clean Energy Transitions Programme 2025
Annual report 2025 The IEA’s Clean Energy Transitions Programme (CETP) helps countries around the world accelerate their transition to clean energy, with a focus on emerging markets and developing economies. By combining global analysis, high-level convening and hands-on technical support, the CETP ensures that evidence, policy guidance and practical tools reach those shaping energy strategies on the ground.In 2025, the CETP has supported almost 350 high-level bilateral meetings with policy makers, over 700 workshops and technical exchanges, involving almost 13 000 participants, and 26 capacity-building events with over 1 700 policy professionals on energy efficiency, data…

Scaling Up Transition Finance Sectoral insights
Where can transition finance be applied? This chapter provides an analysis of investments that can be supported by transition finance in three important areas – heavy industry, critical minerals and natural gas – building on the preceding assessment of investments and providing illustrative cases and non-exhaustive key performance indicator (KPI) examples to underpin transition strategies.As with the investment amounts highlighted in Chapter 1 that can be supported by transition finance, inclusion here does not automatically render an activity eligible for transition finance, since such eligibility depends on meeting the relevant process requirements. Equally, the absence of an activity from this…

Luxembourg
Luxembourg has a fossil fuel intensive energy mix driven by a high demand for transportation fuels, notably from transiting freight trucks and commuters. Despite this demand, the country is committed to reducing emissions. Its climate law sets targets for a 55% emission reduction by 2030 and climate neutrality target by 2050. The government has adopted numerous measures to push for energy transition, including a carbon tax which was introduced in 2020 and encouraging renewable generation through subsidies and auctions. Several programmes also support energy efficiency in buildings, industry and transportation, with a target for 49% of all passenger cars to…

Energy Efficiency in China’s Buildings Sector
Policy opportunities Over the past two decades, China has made significant strides in energy efficiency, with strong reductions in primary energy intensity across the economy and increased energy services. Much of China’s improvement has come from energy efficiency upgrades in industry and overall economic structural shifts. The buildings sector accounts for approximately 20% of its total final energy consumption and its intensity has decreased at a slower rate. There remains significant potential to unlock further energy savings through technical and policy initiatives in buildings.This report outlines opportunities for actions, targets and timelines that could improve energy efficiency in…
