Currently, substantial gas resources are being produced that do not make it to market because they are lost to flaring and leaks across the oil and gas supply chain. This report estimates that nearly 210 billion cubic meters (bcm) of natural gas could be made available to gas markets by a global effort to eliminate non-emergency flaring and reduce methane emissions from oil and gas operations. This would also avoid around 0.1C of warming by mid-century. The report includes a dataset with regional estimates of flaring, methane emissions, and abatement opportunities.
