3 emissions arising during the combustion of methane by the end user are not included in the OGMP framework. The Global Methane Alliance (GMA) is a Climate and Clean Air Coalition (CCAC) initiative that encouraged governments to explicitly include methane as part of their overall GHG reduction targets in their Nationally Determined Contributions in the lead-up to COP26. OGMP 2.0 builds on the reduction targets established in the GMA. The Clean Air Task Force, a partner to GMA, provides technical and policy assistance to countries committed to reducing methane emissions (CATF, 2022).  Oil and Gas Climate Initiative (OGCI) OGCI is a CEO-led industry initiative launched in 2014 to take practical actions on climate change. Reducing methane emissions is a priority area for OGCI, with the objective to achieve near-zero methane emissions across the oil and gas industry and along the full value chain. All OGCI members commit to reducing their methane intensity target to well below 0.20% by 2025. OGCI members report progress annually, and over the last five years reduced their aggregated methane emissions by more

than 30%. In March 2022, this commitment was strengthened via the Aiming for Zero Methane Emissions initiative (see Figure 7 ). Signatories strive to reach near-zero methane emissions from operated oil and gas assets by 2030. OGCI encourages all oil and gas companies to join this initiative.  Methane Guiding Principles (MGP) An industry initiative managed by OGCI, MGP prioritises actions on the natural gas supply chain, from production to the final consumer (see Figure 8 ), (MGP, 2022). MGP signatory companies commit to reporting publicly on progress with five MGPs:  Continually reduce methane emissions  Advance strong performance across the gas supply chain  Improve accuracy of methane emissions data  Advocate sound policy and regulations on methane emissions  Increase transparency MGP provides 10 Best Practice Guides and a Best Practice toolkit with the reporting framework.
