Manure management for methane mitigation - Improved inventory modelling to support policy actions

Manure management is a main source of methane (CH4) emissions. Mitigation options such as biogas treatment exist, but effects cannot be verified and are not accounted for in inventories.

In this project, a new method to estimate CH4 emissions from manure will be used to investigate farm-level greenhouse gas mitigation, and for upscaling to national inventories. Partners are DE, DK (coord.), NL, SE and the company BPC Instruments.

Experimental results are used to parameterise sub-models of daily CH4 emission for use in analysing country-specific scenarios with the model FarmAC. GHG mitigation scenarios are studied, and the results may be up-scaled and used for inventories at farm- and country-level.

A presentation VIDEO from autumn 2021.

On 23 February 2023, a WEBINAR was organised with presentations from global experts and the M4Models project: “Methane emissions from manure management – monitoring and mitigation”. It was a success with nearly 200 attending from more than 20 countries.
