Global Energy and Climate Model Net Zero Emissions by 2050 Scenario (NZE)
The International Energy Agency (IEA) was asked by the COP26 Presidency in 2021 to give an indication of what achieving the 1.5 °C goal would mean for the energy sector. Responding to this request, the Net Zero Emissions by 2050 Scenario (NZE Scenario) was developed. It represents a global pathway towards the goal of limiting global warming to 1.5 °C, but not the only possible one. The IEA has always been clear that there are various paths to reach this objective and that each country will have its own route. Since 2021, the IEA has updated its NZE Scenario each year…

Pledges to Progress 2025 Summary of results
The Turning Pledges into Progress framework contains a total of 25 metrics in three categories: 1) target setting (“Targets”), 2) strategies for implementation (“Strategies”), and 3) disclosure and reporting (“Disclosure”). Target setting comprises six metrics related to emissions reductions and investment in clean energy. All the signatories to the Oil and Gas Decarbonization Charter (OGDC) are assumed to have the aim of achieving these targets. Strategies for implementation comprise eight metrics that describe steps companies can take to achieve these targets; and disclosure and reporting comprises 11 metrics allowing stakeholders to assess how companies publicly report information relevant to achieving the OGDC goals…

Energy Efficiency Policy Toolkit Buildings
Introduction Buildings account for about 30% of final energy consumption globally and more than half of electricity consumption. Doubling the global annual energy intensity improvement by 2030 would require buildings to become more efficient rapidly. An integrated policy approach combining regulation, information and incentives is the most effective way to achieve this goal. Regulatory standards such as building energy codes are among the most effective policies to not only boost energy performance and reduce emissions, but also to improve occupants' health, comfort and productivity – while enhancing climate resilience and mitigating energy price fluctuations. Buildings built after a code is introduced can…

What Next for the Global Car Industry Present and future prospects of electric car manufacturing
Highlights New market-entrants focusing on electric car production are expanding rapidly. Pure-play electric car makers, especially those from China and US-based Tesla, are capturing a growing share of sales; some 45% of global electric car sales in 2024 are from pure-play electric car makers, compared to 35% in 2019. The growth in electric car sales affects both car makers and automotive suppliers, especially those producing powertrains and related components. The automotive supplier market is worth about USD 1.3 trillion, equivalent to over 40% of the global car market. For all components except batteries, companies from…

World Energy Investment 2026 How we track investment in energy
Tracking energy investment The way investment is measured across the energy spectrum varies, largely because of differences in the availability of data and the nature of expenditures. This document highlights the methodology used to ensure that the estimates are consistent and comparable across sectors in the World Energy Investment 2026 (WEI 2026) report and other publications from the International Energy Agency. The IEA measures investment as the ongoing capital spending on assets. For some sectors, such as power generation, this investment is spread out evenly from the year in which a new plant or upgrade of an existing one takes…

Global EV Outlook 2025 Electric vehicle batteries
Trends in battery demand Global battery demand for the energy sector hit the 1 TWh milestone in 2024 Electric cars remain the main driver of battery demand, but demand for trucks nearly doubledBattery demand in the energy sector, for both EV batteries and storage applications, reached the historical milestone of 1 TWh in 2024. Demand for one average week alone in 2024 exceeded the total demand for an entire year just a decade earlier. Demand was largely driven by growth in EV sales, as demand for EV batteries grew to over 950 GWh – 25% more than in 2023. Electric cars remain the…
