Abstract

Carbon dioxide (CO2) is a known greenhouse gas. According to the IPCC 6th assessment report (2021) CO2 has had a radiative forcing value of +2.16 W m-2 between 1750 and 2019, making it one of the largest contributors to global warming in the Earth’s atmosphere. Remote detection and measurement of industrial emissions of CO2 are not routinely carried out, rather they are calculated from the fuel combusted or measured directly within ducted vents. In certain circumstances this is not always possible for example leaks from CO2 pipelines. We have demonstrated the successful measurement of CO2 emissions remotely using the differential absorption lidar (DIAL) technique at a wavelength of ~ 2µm.
