The systems and methods are configured to determine emissions savings achieved by converting natural gas-powered pneumatic control systems to compressed instrument air systems. An amount of methane and/or carbon emissions savings is determined by calculating, in real-time, the amount of compressed air used by a pneumatic system and converting the amount of compressed air into an equivalent amount of methane and/or carbon emissions that would have been emitted into the atmosphere had the pneumatic system been operated by natural gas and/or electric power. ## Claims ### Claim 1 A system for determining methane emissions savings from operating a compressed air-powered pneumatic system, the system comprising: an air compressor configured to transmit air through a conduit;
