If you build it... - The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) and the International Code Council have launched a second public review for proposed Standard 240P, which provides a unified methodology for quantifying both embodied and operational GHG emissions across the life cycle of buildings and their sites. The public comment period runs from June 6 to July 21. Updates from the first draft include clearer definitions, an updated life-cycle figure, a revised default metric (shifting from GWP-20 to GWP-100), and more detailed guidance on embodied emissions. The standard aims to support professionals, regulators, and investors with consistent tools for transparent GHG reporting. The draft is available at osr.ashrae.org. ASHRAE is an international society of more than 50,000 heating, refrigerating and air-conditioning professionals from over 132 nations.

Bonn chance - The UN's dwindling budget, the global roadmap to $1.3 trillion per year of climate finance, the international work programme for mitigating climate, and the Global Goal on Adaptation are at the top of the agenda for climate negotiators meeting in Bonn over the next 10 days, UNFCCC Executive Secretary Simon Stiell said on Monday morning, opening the intersessional, SB 62. The UNFCCC has found "significant cost savings and efficiencies" in its budget to deliver on its growing mandates, but it's not a sustainable approach, Stiell said, urging countries to address them during the Bonn negotiations. The meeting should also deep-dive into the Baku to Belem Roadmap to $1.3 Trillion, making it a how-to-guide with clear next steps, he said.
