This is particularly important as the demand for sustainable energy sources continues to grow, and as consumers and businesses increasingly scrutinise the authenticity of ‘green’ labels. The ability to differentiate between carbon-based and sustainable production processes increases transparency and creates additional incentives for oil and gas companies to implement environmentally friendly processes. By integrating this analytical technology into existing certification processes, stakeholders can ensure that the fuels used actually meet the promised environmental standards. This innovation will help reduce CO2 emissions, increase confidence in the use of green fuels and set the course for a more sustainable energy and transport future.
