Publications

An Eye on Methane 2025 cover
An Eye on Methane 2025: From Measurement to Momentum
The UN Environment Programme’s International Methane Emissions Observatory (IMEO) annual report, An Eye on Methane: From measurement to momentum, finds that data-driven solutions to rapidly target methane action are available – but progress to scale action must accelerate across governments and companies.
An Eye on Methane 2024 cover
An Eye on Methane: International Methane Emissions Observatory 2024 Report
The fourth edition of UNEP’s International Methane Emissions Observatory (IMEO) publication, An Eye on Methane, Invisible but not unseen, takes stock of progress harnessing a methane data revolution that can accelerate methane reduction at a global scale.
An Eye on Methane 2023 cover
An Eye on Methane: the road to radical transparency — Annual Report 2023
This report takes stock of progress harnessing an imminent data revolution that can accelerate methane reduction on a global scale. Credible data has the potential to deliver the transparency needed for rapid climate action, but only if reconciled, integrated and put into the hands of those who can act on it.
An Eye on Methane 2022 cover
An Eye on Methane: International Methane Emissions Observatory 2022 Report
This report delves into the progress made to achieve deep reduction of methane emissions, starting with the fossil fuel sector. We need a strong basis for action grounded on improved emissions data to close the emissions gap and reduce warming in the short term.
An Eye on Methane 2021 cover
An Eye on Methane: International Methane Emissions Observatory 2021 Report
This report describes how state actors can take action to curb methane emissions from the fossil fuel industry, and what progress has been made as part of the decarbonization process, particularly in the energy sector.
