Fossil Fuel Subsidies
This approach compares average end-user prices paid by consumers with reference prices that correspond to the full cost of supply. The price gap is the amount by which an end-use price is short of the reference price. Its existence indicates the presence of a subsidy. In a given economy, the basic calculation of subsidies for a product is:Subsidy = (Reference price - End-user price) × Units consumedThese calculations require substantial data. End-user price and consumption data are drawn from IEA data and, where necessary, from government sources and other reports. The estimates are also sensitive to reference…

Global Energy and Climate Model About the Global Energy and Climate Model
Overview Since 1993, the IEA has provided medium- to long-term energy projections using a continually evolving set of detailed, world-leading modelling tools. First, the World Energy Model (WEM) – a large-scale simulation model designed to replicate how energy markets function – was developed. A decade later, the Energy Technology Perspectives (ETP) model – a technology-rich bottom-up model – was developed for use in parallel to the WEM.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…

Prospects for Natural Gas Certification Executive summary
Governments and industry are working to improve resource efficiency and reduce emissions from natural gas supply – from both domestic production and imports – to help deliver on their climate goals, while also looking to improve energy security. One emerging approach is natural gas certification, which can help buyers make more informed decisions by providing independently verified greenhouse gas (GHG) intensity data at select stages of the supply chain, from production and processing to storage and transport, but excluding final consumption. This can support the implementation of best practices throughout the entire supply chain, and help importing countries and regions better understand…

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…

Global Energy and Climate Model Techno-economic inputs
The Global Energy and Climate Model (GEC Model) uses macro drivers, techno-economic inputs and policies as input data to design and calculate the scenarios. The values for the different data categories and scenarios used in the GEC Model 2025 can be downloaded here.In particular more details regarding power generation technology costs for the Current Policies Scenario, the Stated Policies Scenario and the Net Zero Emissions by 2050 Scenario can be downloaded in excel format, including detailed projections at the 2050 horizon regarding overnight capital costs, annual O&M costs, efficiencies and other contributors to electricity costs at regional…

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…
