Methane Tracker Database and Methane Abatement Model
Database of country and regional estimates for methane emissions and methane abatement potential and the associated cost of abatement by country, segment and reduction technology. This database presents the IEA’s country-by-country estimates of energy-related methane emissions. For coal supply and the oil and gas sector, we present detailed estimates for the abatement potential – and costs or savings – from different technology and policy options.The interactive version of the Methane Tracker Database also includes detailed policy information and comparisons with other sources of methane emissions estimates.The IEA Methane Abatement model is a tool that allows users to estimate…

Hydrogen Production and Infrastructure Projects Database
Tracks data on projects for the production of hydrogen for energy or climate change-mitigation purposes and the development of hydrogen infrastructure The IEA produced these datasets as part of efforts to track advances in low-emissions hydrogen technology.The Hydrogen Production Projects Database covers all projects commissioned worldwide since 2000 to produce hydrogen for energy or climate change-mitigation purposes. It includes projects that have the objective either to reduce emissions associated with producing hydrogen for existing applications, or to use hydrogen as an energy carrier or industrial feedstock in new applications that have the potential to be a…

Global Energy Review: CO2 Emissions in 2021
Global emissions rebound sharply to highest ever level The global CO2 emissions and energy demand numbers are based on the IEA’s detailed region-by-region and fuel-by-fuel analysis, drawing on the latest official national data and publicly available energy, economic and weather data. Combined with the methane emissions estimates published by the IEA and estimates of nitrous oxide and flaring related CO2 emissions, this new analysis shows that overall greenhouse gas emissions from energy rose to their highest ever level in 2021.

The Role of Critical Minerals in Clean Energy Transitions
Minerals are essential components in many of today’s rapidly growing clean energy technologies – from wind turbines and electricity networks to electric vehicles. Demand for these minerals will grow quickly as clean energy transitions gather pace. The World Energy Outlook Special Report The Role of Critical Minerals in Clean Energy Transitions provides the most comprehensive analysis to date of the complex links between these minerals and the prospects for a secure, rapid transformation of the energy sector. Alongside a wealth of detail on mineral demand prospects under different technology and policy assumptions, it examines whether today’s mineral investments can…
