The building and construction sector play a critical role in global greenhouse gas emissions. Measuring and understanding these emissions is essential to plan and implement mitigation policies. Effective national strategies and measures to reduce GHG emissions can only be developed based on a solid understanding of the emissions over the entire building life cycle, from the production of building materials, to the construction, operation and, finally, the demolition and potential reuse of a building.
The UNFCCC Compendium on Greenhouse Gas Baselines and Monitoring in the Building and Construction Sector published by UNFCCC and developed by PEEB and BPIE includes two parts. The first part provides an overview of the different sources of GHG emissions from the building and construction sector, as well as methodologies for quantifying these emissions to feed into the preparation and reporting of national GHG inventories. The second part concerns itself with different mitigation actions, strategies, and policies to reduce GHG emissions from the buildings and construction sector. The Compendium will be launched at aside event in summer.
Based on the compendium, PEEB will publish methodological guidance on how to measure greenhouse gas emissions from buildings in 2022, including for climate finance proposals. This information will be widely shared within the context of the GlobalABC.
