Outlook for Biogas and Biomethane Assessing the sustainable potential and cost of feedstocks for biogas and biomethane
Feedstock assessment This assessment considers over 30 types of feedstocks for biogases. They can be broadly grouped together as crop residues, animal manure, biowaste and woody biomass. We assess feedstocks that can be processed without direct competition with food for agricultural land or animal feed, and that do not have any other adverse sustainability impacts. Biogas and methane yields are key indicators of how suitable a feedstock is for energy production. Biogas yield refers to the total volume of gas produced from a feedstock through anaerobic digestion, primarily methane (CH₄) and CO₂. Methane yield, by contrast, accounts only for the…

World Energy Investment 2025 Source, flows and destination of global energy-related investment spending
Most energy investment is supported by commercial finance and made by private sponsors, but the sources of finance vary widely by technology and region. Today, 75% of the available finance for investment in the energy sector is commercial finance, but domestic and international public finance play important roles that vary widely across regions and sectors.

Global Methane Tracker 2026 Regional insights
Central and South America The fossil fuel sector in Central and South America emitted just under 8 million tonnes (Mt) of methane in 2025, around half of which was from oil and gas facilities in Venezuela. Oil and gas facilities are the main sources of methane emissions in Venezuela, Argentina and Brazil, whereas in Colombia emissions are split roughly evenly between coal mining and oil and gas activities. In Venezuela, the upstream methane emissions intensity of oil and gas operations is nearly six times the global average, and flaring intensity is around 12 times higher. The intensities of operations in Argentina…

Global Methane Tracker 2026 Understanding methane emissions
Atmospheric methane concentrations continue to rise Methane (CH4) is the second-most harmful greenhouse gas after carbon dioxide (CO2), trapping outgoing heat and warming the atmosphere through a process known as radiative forcing. Though it lingers in the atmosphere for far less time (12 years, compared with centuries for CO2), methane absorbs substantially more energy while it does. Cutting methane emissions therefore promises significant near-term climate benefits. Methane carries other hazards, too: it contributes to the formation of ground-level (tropospheric) ozone, a harmful pollutant, and methane leaks can also pose explosion risks.Atmospheric methane concentrations today are 2…

The Implications of Oil and Gas Field Decline Rates Executive summary
…by 2024 this share had fallen to 77% as a result of rising output from unconventional fields. In the case of natural gas, around 70% of the 4 300 billion cubic metres (bcm) produced today is from conventional fields, with nearly all of the rest being shale gas produced in the United States. Even with the shale revolution, overall oil and gas output still relies heavily on a small number of supergiant fields, largely in the Middle East, Eurasia and North America, which together accounted for almost half of global oil and gas production in 2024.Detailed analysis of the production records…

Daniel Wetzel
Head of Tracking Sustainable Transitions Unit. Daniel Wetzel leads the newly created Tracking Sustainable Transitions unit within the World Energy Outlook, which tracks how policy measures are actually moving the needle on clean energy transitions, energy access, and energy employment. He was one of the lead author’s on the IEA’s Sustainable Recovery report, the IEA’s Sustainable Recovery Tracker, and coordinated IEA’s co-custodianship on Tracking Progress on Sustainable Development Goal 7.1: Universal Access. Daniel also oversees the employment and parts of the demand analysis in the annual World Energy Outlook. Prior to joining the IEA, Daniel worked at the Rocky Mountain Institute in their Beijing office, leading their Power Market Reform program, and also in Colorado, working on regional energy transition plans.
