New Zealand
New Zealand has a diversified energy mix, with significant production of both hydropower and geothermal. As the country embarks on an ambitious energy transition, it has many natural advantages, including a strong renewable resource base. New Zealand already has a low-emissions electricity system, with over 80% of electricity coming from renewable sources. The key challenge will be to decarbonise other end-use sectors through clean power and support investments in new technologies to achieve deeper emissions cuts across all sectors. Notably, the transport sector accounts for the highest share of emissions and is almost entirely dependent on oil while…

Ireland
Ireland put in place an ambitious and comprehensive set of policies and targets to reach net zero by 2050 and 80% of renewable electricity generation by 2030, but now their implementation needs to accelerate. Natural gas will remain an important part of the energy mix at least until the mid-2030s, especially to meet peak electricity demand, but offshore renewable energy will become the cornerstone of Ireland’s energy transition beyond 2030. Given Ireland’s current exclusive reliance on energy imports from the United Kingdom, energy security is a major concern to the government while transitioning to a (variable) renewables…

Why the growth of energy service companies is uneven globally
ESCO The global annual ESCO market growth rate has more than doubled over the past five years Energy efficiency is one of the most cost-effective tools for enhancing energy security, reducing household energy bills and supporting countries’ efforts to reduce emissions. Energy service companies (ESCOs) – firms that develop and implement energy efficiency projects typically financed through verified energy savings – are playing a growing role in delivering energy efficiency improvements across buildings, industry and transport infrastructure worldwide. By integrating project development, financing and performance guarantees, ESCOs can offer a proven way to reduce upfront investment barriers and shift technical and…

Global Hydrogen Review 2026 Trade and infrastructure
…pipeline length has increased by 70%. Activity remains concentrated in Europe and China, which saw major milestones in 2025, as China began construction of the world’s longest hydrogen pipeline, and Germany completed the world’s longest repurposing of a natural gas pipeline.Announced underground hydrogen storage projects could provide 11 TWh of capacity by 2035 (335 kt H₂), but just over 7% has reached final investment decision (FID) or is under construction, equivalent to 0.6% of the estimated throughput from committed low-emissions hydrogen projects. Large-scale salt caverns are in construction in the United States, Germany and China.Around 170 ammonia…

Sustainable Transport for Georgia: A Roadmap
…and climate pollution, and road injuries and deaths).Since national and municipal policies shape transport technology, infrastructure and operations, the report first examines the country as a whole, followed by Georgia’s largest cities. With road vehicles responsible for more than 98% of domestic transport energy use and carbon dioxide (CO₂) emissions, the focus is on road transport.Opportunities identified include improving vehicle efficiency – particularly by accelerating electric vehicle (EV) adoption – and cutting reliance on inefficient vehicles by reducing unnecessary car travel and shifting to buses, metro, walking and cycling, as well as intercity passenger and freight rail. These opportunities…

Rare earth elements 2025
Outlook for key energy transition minerals This report provides an outlook for demand and supply for key energy minerals including copper, lithium, nickel, cobalt, graphite and rare earth elements. Demand projections encompass both key energy technologies and other uses under different IEA Scenarios. Supply projections are based on a detailed review of all announced projects. They show how today's geographical concentration evolves over time, for both mining and refining and how expected supply compares with primary supply requirements.

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…

Renewables in District Energy
…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 pumps and thermal energy storage. It also sets out policy priorities for three types of markets: established systems with high renewable shares, fossil fuel-intensive networks, and emerging or untapped district energy markets.

Investment in next-generation geothermal is surging. Policies are key to further growth
Next-generation geothermal readies for take-off Next-generation geothermal is seeing a burst of financing, innovation and new supply agreements Geothermal energy harnesses naturally occurring heat found beneath the Earth’s surface to provide heating and cooling, electricity and energy storage. As global electricity demand rises and power systems place a growing premium on firm supply, geothermal energy’s ability to provide an around-the-clock, low-emissions source of power is attracting renewed attention. However, easy-to-access conventional geothermal resources are relatively rare and mostly confined to a small number of shallow geothermal hotspots globally, accounting for…

COP28: Tracking the Energy Outcomes
…For the first time, governments explicitly recognised that to achieve this target, energy-related emissions need to reach net zero by 2050, and they set key goals to help meet this objective – including tripling global renewable energy capacity and doubling global energy efficiency improvements by 2030, and deploying emerging technologies, such as low-emissions hydrogen and carbon capture.The IEA, in collaboration with the United Nations Framework Convention on Climate Change (UNFCCC) Secretariat, is tracking progress towards the energy objectives established at COP28. This forms part of our broader work, at the request of governments, to support the full and…
