Global consultation opens on how to measure a building’s emissions


Feedback is being sought on a proposed international standard for the evaluation and documentation of greenhouse gas (GHG) emissions across a building’s life cycle

Published by ASHRAE and the International Code Council (ICC), Standard 240P – Quantification of Life Cycle Greenhouse Gas Emissions of Buildings will provide a methodology to quantify the embodied and operational GHG emissions associated with buildings and their sites. The standard will also provide minimum requirements for documentation of life cycle GHG emissions.

The standard is intended to support building industry stakeholders, governments and the finance and investment industry in implementing a common platform for measuring, reporting and acting upon the GHG emissions of buildings.

“Standard 240P will play a pivotal role in addressing embodied carbon and significantly impacting the built environment’s greenhouse gas (GHG) emissions, particularly within mechanical, electrical, and plumbing (MEP) systems,” says 2023-24 ASHRAE President Ginger Scoggins, P.E., Fellow ASHRAE.

“We are pleased to collaborate with the International Code Council (ICC) on this standard, recognising the joint effort’s potential to advance effective solutions and contribute to a more sustainable future.”
