Honeywell, Samsung E&A, Johnson Matthey and Gidara Energy have joined together to create a strategic sustainable aviation fuel (SAF) technology group. The four companies, organized as the SAF Technology Alliance, aim to create a new technology offering to help scale and deliver a full-service SAF production chain to take the fuel from a waste feedstock to a final product. This alliance will look to scale the use of gasification and the Fischer-Tropsch process—a chemical reaction that makes synthesis gas—in SAF production in the near term. Read more

Amazon said Monday that it will spend $20 billion on two data center complexes in Pennsylvania. One data center is being built next to northeastern Pennsylvania’s Susquehanna nuclear power plant, where it intends to get its power. The other will be in Fairless Hills at a logistics campus, the Keystone Trade Center, on what was once a U.S. Steel mill. Amazon said that data center will get its power through the electricity grid.

The next era of corporate climate leadership is already underway and it's nothing like the last one. Gone are the glossy pledges and PR campaigns. In their place: rigorous procurement, strategic multiyear commitments and quiet, confident execution. Since last year, we’ve seen major corporations exit climate coalitions, record outflows from environmental, social and governance funds and the Net-Zero Banking Alliance–the UN-backed banking coalition supporting Paris climate goals through financing–softening its targets.

ANSI/ASHRAE Standard 228, Standard Method of Evaluating Zero Net Energy and Zero Net Carbon Building Performance. It contains a method of evaluating a building, or group of buildings, to determine if they’ve achieved “zero net energy” and/or “zero net carbon” operation. This article outlines measurement methods contained in Standard 228, details of its development and how it compares and interacts with other carbon-related ASHRAE standards. Download here

Held in Chicago from Oct. 22-24, the 2025 Building Decarbonization Conference will be an information and idea exchange between stakeholders in the built environment industry concerning the reduction of GHG emissions in new and existing buildings and systems. The conference will bring together engineering and technical solution providers with building owners, utility program managers, local governments and financial services providers who are increasingly challenged to meet stringent building decarbonization goals, policies and regulations in a practical, cost-effective manner.

As summer temperatures begin to rise across the country, a headache is also heating up for the air conditioning industry. A shortage of R-454B refrigerant, the eco-friendly coolant poised to replace older formulas, is threatening to disrupt cooling systems at the worst possible time. Manufacturers have issued warnings about potential legal and damage concerns about refrigerant mixing as a strategy to mitigate the shortages. Read more
