Subject to long-range transport of polluted air masses, while the east was Our analysis suggests that during theĬampaign the European part of Russia's Arctic and western Siberia were Mixing ratios from all flights are lower (408.09–411.50 ppm vs. Median CH 4 mixing ratiosĪre fairly higher than the monthly mean hemispheric reference (Mauna Loa, Measured ozone (O 3) andĬarbon monoxide (CO) are used here as tracers. ![]() CH 4 and CO 2 were measured in situ during theĬampaign and form the core of this study. A large-scaleĪircraft campaign took place in September 2020 focusing on the SiberianĪrctic coast. Methane (CH 4) and carbon dioxide (CO 2) in the vulnerable ArcticĮnvironment is required to better predict climate change. The platform will bring together and release emissions data collected and integrated from diverse data streams.A more accurate characterization of the sources and sinks of They include livestock (responsible for 33 per cent of methane emissions), oil and gas, waste and landfills (over 20 per cent), coal mining (12 per cent,) and rice cultivation (nearly 10 per cent).Īt the upcoming UN Climate Change Conference COP27, to be held in Sharm El-Sheikh, Egypt in November 2022, the Observatory will launch the first iteration of its public “data to action” platform, the Methane Alert and Response System (MARS). The UNEP Observatory’s focus has also now expanded to cover other major categories of emitters, collectively responsible for 75 per cent of methane emissions in 2017. Who is emitting, where, and how much? What you do not measure, does not get addressed,” said Kadri Simson, European Commissioner for Energy. “To reduce methane emissions, we need to know more. That aims to bring about a reduction of global methane emissions by 30 per cent, by 2030. The lack of reliable emissions data has made it hard for governments to carry out targeted action at the scale and speed needed to achieve the objectives of the Global Methane Pledge (GMP) launched during the UN Climate Conference COP26 last year by over 120 countries. The International Methane Emissions Observatory is creating the world's first global public database of empirically verified methane emissions, starting with the fossil fuel sector, at a level of granularity and accuracy never achieved before. This represents a large discrepancy between the estimates of global industry emissions and the proportional share reported by partnership’s member companies.Īlthough the quality of reported data has improved, the agency warns that the majority of assets are not yet reporting measurement-based emissions, and a significant amount of assets non-operated by OGMP 2.0 member companies haven’t been reported yet.Ĭlean energy, like wind power, is a key element in reaching net zero emissions. Yet, total emissions from this year’s reporting by OGMP 2.0 member companies are 1.3 million tons of methane for both operated and non-operated assets. Meanwhile, recently published studies set the estimate for total global methane emissions from the industry at 80-140 million tons per year, while the International Energy Agency’s (IEA) methane tracker estimates emissions at the lower end of this range. However, twelve member companies are not on track: two lost their Gold Standard status compared to last year, seven did not achieve it either year, and three companies reporting for the first time in 2022, did not achieve it. Sixty members are on the programme’s “Gold Standard” pathway – having committed in their implementation plans to sequentially improve the quality of their reported data – and are showing progress in moving towards measurement-based estimates of methane emissions. The report covers the second year of progress of the Oil and Gas Methane Partnership 2.0 (OGMP 2.0), UNEP’s flagship mechanism to help companies target mitigation actions and allocate capital efficiently.
