A Danish Energy Agency study was conducted from 2019-2021 to measure methane emissions in 60 biogas plants. The study revealed a leak rate of 2.5% from biogas production. In 2023, a Danish regulation was implemented with the goal of limiting emissions of methane from biogas plants. The regulation requires annual leak detection, reporting, and implementation of a customized leak detection and repair program. It also enforces an emissions cap of 1% methane loss from upgrading equipment. Measurement campaigns in 2024 and 2025 are planned to assess the effects of the regulation and provide a new emissions factor for national greenhouse gas reporting.
