The project will provide improved CO₂ and CH₄ isotope ratio reference materials and traceability chains for spectroscopic techniques. At the end of the project in 2023 the improved discrimination between natural and manmade sources of GHGs will aid governmental agencies to better attribute emission sources, help demonstrate compliance to national reduction targets and enhance the effectiveness of future abatement strategies. The EMPIR programme is co-financed by the Participating States and from the European Union’s Horizon 2020 research and innovation programme.

Collaboration with 13 European research groups, coordinated by NPL.
