Global Methane Pledge (e.g. Azerbaijan),

A the Oil and Gas Decarbonization Charter (e.g. PetroChina) and the Oil and Gas Methane Partner- ship 2.0 (e.g. the Nigerian National Petroleum Company).

The voluntary Oil and Gas Methane Partnership 2.0 is the fagship oil and gas reporting and mitigation program of the United Nations Environment Program (UNEP) and now covers more than 42% of global oil and gas production.

Reporting advances from Level 1 through Level 5, with

Level 4 reporting consisting of source level measurements and Level 5 consisting of two parts: site level measure- ments and reconciliation with the source level measure- ments from Level 4.

In April, responding to the continuous engagement with

There is no ‘one-size-fits-all’ such schemes, Ipieca, the International Association of Oil combination of technologies & Gas Producers (IOGP), the Oil and Gas Climate Initia- tive (OGCI) and the Energy Institute released an update for methane emissions of their “Recommended practices for methane detection and quantifcation technologies – upstream” as well as an detection and quantification.

The update includes six new technologies: Environmental conditions are also important. Cloud • CI Systems: Metcam (a fully integrated, stationary cover can affect the refected sunlight that passive sensors quantifying optical gas imaging (OGI) device) use to detect methane, snow cover can impact refectivity, • Exploration Robotics Technologies: Xplorobot affecting some laser-based technologies, and high winds Laser OGI (a handheld leak screening tool) can disperse methane making it harder for sensors to detect • FLYLOGIX: fxed wing drones for offshore methane plumes. These environmental conditions are also specifc measurements critical to conducting successful measurement campaigns. • Net Zero Aerial: UAS Drone In January, SINTEF Research Engineer Daniel Frank- (a drone-based emission sensor) lin Krause released a technical memo summarizing the • Sierra Olympia Technologies: LWIR OGI organization’s approach to quantifying offshore methane Camera Core (an optical gas imaging camera) emissions in support of OGMP 2.0 Level 5 reporting. • University of Calgary: PoMELO SINTEF has used the measurement strategy twice on Gjøa (a tr uck-based measurement system).
