The National Physical Laboratory (NPL) is partnering with Astrium Services to deliver a new emissions measurement service to enable countries and cities to better quantify their greenhouse gas (GHG) emissions.
This unique new service will provide actual measurements of carbon dioxide, methane and carbon monoxide that will be fed into a sophisticated atmospheric model to provide highly accurate analysis that complements existing reporting methods.
Emissions from a nation or a city are currently calculated using the 'inventory approach'. Through this activity, data such as the number of miles driven by an average person are multiplied by 'emissions factors' which turn that activity data into the tonnes of carbon dioxide equivalent.
The new service will complement and improve these methods by using actual emissions measurements taken from the atmosphere and integrating them into the models used to produce a value for country or city-wide emissions.
The measurements will be taken at permanent elevated sites round the country, from aircraft and eventually use satellite measurement of carbon dioxide too. These measurements will then be fed into the sophisticated model, to be merged with inventories of natural and manmade GHG sources and sinks. This combination of actual measurement with traditional modelling will enable better validation of energy saving and decarbonising measures and determine if they are having the intended effect of reducing actual GHG emissions.
NPL will produce the highest-quality calibration gas standards to underpin the quality of the data used in the service. This is important as data quality is critical when looking for small changes over a number of years.
Jane Burston, Head of the Centre for Carbon Measurement at NPL, said: "Nations are incentivising their citizens and industries to reduce their GHG emissions. They are putting in place alternative ways of generating energy with fe
