Carbon pricing is an importantinstrument in addressing climate change. However, awell-functioning carbon pricing instrument needs a robustframework to quantify GHG emissions (including removals)underpinned by high quality data. This data can help policymakers set the level of a carbon tax (CT) and helpregulators track how many emissions allowances companiesneed to surrender under an Emissions Trading System (ETS). Arobust framework will facilitate implementation andenforcement of the rules and increase compliance levels.This report builds on the PMR Guide for Designing MandatoryGreenhouse Gas Reporting Programs (PMR MRV Guide), whichprovides a broader overview of establishing an MRV system.This report focuses on the technical detail ofquantification protocols, that is, how in practice emissionsdata can be monitored and quantified for reporting. Thisreport is intended for policy makers and governmentofficials responsible for setting up and implementingemissions quantification protocols as part of the emissionsmonitoring, reporting, and verification (MRV) systems thatsupport carbon taxes and emissions trading systems.
