A smart greenhouse gas sensor, sensitive and selective enough to offer a step change in the accurate and agile monitoring needed for evidence-based policies that tackle climate change, has been developed.
As climate change increases the risk of extreme weather events, there is a pressing need to monitor the contributory greenhouse gases, especially carbon dioxide, nitrous oxide and methane.
While the emissions monitoring systems used by many national agencies are highly sensitive – able to distinguish between different atmospheric gases – they tend to be complex, bulky and expensive. Consequently, they are employed chiefly as static reference points, installed in only a few specific locations.
“To offer a more comprehensive picture you would need a significant number of such emissions monitoring systems, covering large areas,” according to Albert Romano-Rodriguez (Micro and Nanotechnology and nanoscopies for Electronic and Electrophotonic Devices (MIND)) project coordinator of the NEOGAS project, which was funded by the Marie Skłodowska-Curie Actions programme.
To increase the options available to authorities and experts, NEOGAS has developed a proof of concept for a low-energy gas sensing device which will leverage internet of things (IoT) functionality for forecast modelling.
