Flared gas values, in both mass and volume units, have been converted to CO2 emissions using emission factors observed in published datasets (e.g. EEMS)*iii. The policies and proposals set out in the Carbon Budget Delivery Plan are quantified using the Net Zero Industrial Pathways (NZIP) model and a range of other policy specific models and analysis. These measures would be subject to future consultation. The modelled scenarios show how differing uptake rates of hydrogen may displace some technologies that rely on electrification (and the policies that support them) across the economy. For domestic buildings, we will seek to grow the market and help consumers transition to different supplies of heat - all while continuing to follow natural replacement cycles and working with the grain of consumer behaviour. For non-domestic buildings, we will focus policy interventions on key segments of the building stock, for example based on tenure or building use.
