MRV TooL
Common Carbon Metric (CCMv2)
The MRV tool to establish whole-of-life greenhouse gas emissions baselines for a building stock will add to the existing/current CCM Excel Tool the following capabilities and functionalities
The Common Carbon Metric (CCM) tool, initially developed by UNEP in 2011 as a Measurement, Reporting, and Verification (MRV) tool, enables the assessment and comparison of operational emissions from buildings globally. HEAT is partnering with the Global Buildings Performance Network (GBPN), who were involved in the original development of the CCM, to update the tool under the IKI ALCBT project. The updated version, CCM v2, will incorporate embodied carbon assessments along with operational carbon. The planned outputs for CCM v2 include:
Updated Common Carbon Metric (CCM v2) Excel-based Tool for a whole-of-life emissions MRV system and baseline and “futureline” emission scenarios for the building stock in a specified area or jurisdiction, and
Content contribution to the development, refinement of CCM manual and training package.
Key Features and Functionality
The MRV tool to establish whole-of-life greenhouse gas emissions baselines for a building stock will add to the existing/current CCM Excel Tool the following capabilities and functionalities:
Addition of embodied greenhouse gas (GHG or carbon) emissions (EmbC) to operational carbon (OpC) of buildings (thus, whole-life carbon, WLC) and renewable energy in its baseline calculations. This includes considerations of:
- Country-specific datasets, including starting/initial values of EmbC (A1-A3 life cycle phases only) for each of the 5 ALCBT countries (Cambodia, India, Indonesia, Thailand and Vietnam)
- Carbon mitigation through renewable energy supply from the grid (off-site) and on-site.
Calculation or estimation of emissions under different future scenarios (“futureline”) by allowing the user to change selected factors that impact projected emissions at given time periods, including:
- Any significant actions such as regulation and policies or introduction of efficient and low-carbon solutions at specified periods, alone or in combination.
- For example, the potential impact of change in building regulations at year X from the starting year of analysis and/or change in the GHG emissions factor in the energy supply at year Y can be compared with the baseline scenario and another scenario with different settings at specified times.
The Carbon Tool is developed by HEAT International GmbH as part of the Asia Low Carbon Buildings Transition (ALCBT) Project, co-implemented by the Global Green Growth Institute (GGGI), ASEAN Centre for Energy (ACE), and Energy Efficiency Services Limited (EESL). The project is funded by the Government of Germany through its Federal Ministry for Economic Affairs and Climate Action (BMWK) under the International Climate Initiative (IKI).
