Draft emissions standard open for comment

February 08, 2024

ASHRAE and the International Code Council (ICC) has released a proposed standard for the evaluation and documentation of greenhouse gas emissions (GHG) across a building’s life cycle.

The proposed ASHRAE/ICC standard 240P – Quantification of Life Cycle Greenhouse Gas Emissions of Buildings – is open for comment until March 18, 2024.

Standard 240P 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 lifecycle 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,” said 2023-24 ASHRAE president Ginger Scoggins.
