Direct Measurement of Landfill Methane Emissions for Defra

About

Department for Environment Food & Rural Affairs awarded a contract to NPL Management Limited for the direct measurement of landfill methane emissions.

The contract, valued at AUD 299,166, involved designing and delivering a robust and cost-effective survey approach to quantify annual site-specific methane emissions from operational and recently closed landfill sites.

The work aimed to replace modelled estimates in the UK National Atmospheric Emissions Inventory with measurement evidence and provide procedures for regulatory settings.

The supplier was required to deliver four objectives: design sampling approach, regimes, and data analysis for a seasonal study; implement a four-season study at operational and closed sites; provide statistical analysis and methodology recommendations; and create a Standard Operating Procedure for sampling and analysis.

The project comprised three work packages, including design of sampling regimes and implementation of the season study.
