Intertek completes independent low methane emissions certification audit for North Sea gas project
23 Feb 2026
Helping energy producers drive down methane emissions while promoting transparency and credibility
London: Intertek, a leading Total Quality Assurance provider to industries worldwide, completed an extensive methane emissions performance assessment of ONE-Dyas’ N05-A gas production facility in the Southern North Sea, resulting in the issuance of a low methane emission certification.
The Dutch-German N05-A gas development, operated by Dutch exploration and production company ONE-Dyas, has become the first natural gas production project in the North Sea to be independently certified as meeting the highest grade under MiQ’s methane emissions standard. The project has achieved a MiQ Grade A rating, following Intertek’s independent audit of its operational practices and measured methane emissions data.
MiQ provides a transparent, rigorous, data-driven grading system to assess natural gas based on methane performance, which helps drive regulatory compliance, incentivise continuous improvement, and ensure methane accountability in the global oil and gas sector throughout the entire supply chain. For N05-A, Intertek’s independent audit verified both the project’s emissions data and the systems in place to manage methane.
Frank Beiboer, Managing Director, Intertek Metoc, commented: “We are pleased to have been selected as the independent MiQ-accredited auditor for ONE-Dyas’ N05-A facility, and excited to see the extensive reporting and verification process through to a successful certification. Not only is this the first MiQ-certified facility in the Netherlands, but it is also the first upstream asset to be certified in Europe. Additionally, it’s the first gas installation in the Dutch and German North Sea to be fully powered by renewable electricity – supplied via subsea power cable from the nearby Riffgat offshore wind farm.”
Flaviu Barsan, Energy Transition & ESG Lead of ONE-Dyas, said: “This MiQ certification relies on an independent and diligent review by accredited auditor Intertek, whose assessment verified both our methane emissions data and the robustness of our operational practices. Achieving this certification supports ONE-Dyas’ broader ESG goals by providing transparent, independently validated assurance of our efforts to minimise environmental impact.”
Intertek, an accredited MiQ Auditor, helps ensure the transparency, credibility, and independence of methane emissions certification. The company certifies natural gas extraction and production facilities against the MiQ standard using data-led grading to identify gas with higher or lower emissions. Following the evaluation of methane intensity, company practices and monitoring technology, the resulting grades allow producers to differentiate their natural gas in the market and benchmark against peers while also creating incentives for cutting methane emissions.
