Our guideline of 1.5 gmp exceeds that of WaterSense and CALGreen. We also suggest performance criteria.

Everyone wants to save water, but low-flow shower units have been faulted for delivering poor performance—leading people to spend more time in the shower or to remove the showerhead and replace it with an older, higher-flow showerhead.... Read more

Many people hope mass timber will drive decarbonization—but scaling that up could make things worse. Instead of embodied carbon alone, “climate-smart” practices focus on our increasingly fragile forests.

February 26, 2024

This is Part Two of a two-part series on wood products. Part One focuses on the embodied carbon of wood products, exploring the origin and veracity of industry carbon-neutrality claims and considering the avoided emissions associated with using mass timber in place of structural steel or concrete. Part Two considers broader climate implications... Read more

Are wood products inherently carbon neutral?

Many people think they are even better: “net carbon storing,” or “carbon negative.” Because of this, the green building community has hoped that mass timber will drive decarbonization.

But it turns out that scaling that up could make things worse instead... Read more

Life-cycle assessment and environmental product declarations reveal embodied carbon and other impacts, but it’s important to know their limits.

February 14, 2024

As part of its economy-wide decarbonization plan, the U.S. government is targeting a building-sector emission cut of 90% from 2005 levels by 2050—and a crucial component of that is reducing the embodied greenhouse gas emissions from building materials and construction.

To achieve this, we need better... Read more

Made from portland cement, aggregates, and water, concrete is one of the most useful and ubiquitous materials on the planet. The portland cement that holds concrete together is responsible for approximately 8% of anthropogenic carbon. That’s because  production involves a process (calcination) that transforms limestone into portland cement and... Read more

You’ve probably heard that wood products are carbon neutral. You might also have heard that timber harvesting causes immense carbon emissions.

Which is it?

Could it be both?

This on-demand webcast investigates these questions and others, using a scientific lens to examine wood’s carbon... Read more

Feature Article

Wood products are widely regarded as carbon neutral—or even better. With new research challenging that idea, a more cautious approach is emerging. Because the climate stakes are too high for us to get this wrong.

January 29, 2024

Editor’s note: Stephanie Carlisle, senior researcher at the University of Washington’s Carbon Leadership Forum, generously provided a technical review.

This is Part One of a two-part series on wood products. It delves into the climate impacts—positive, negative, and otherwise—of managed forests. Part Two considers more climate... Read more

Is wood carbon neutral? Can mass timber buildings be net-negative emitters? 

You have probably heard both of those claims repeated by manufacturers, colleagues, and the media—but the World Resources Institute isn’t so sure. A WRI report released in July 2023 maintains that wood use is not carbon neutral “even if... Read more

Science-based targets for the building sector no longer apply to design firms and most construction companies, but AEC must continue leading the industry toward net zero, experts say.

January 17, 2024

It’s 2024. Global emissions—and temperatures—are rising instead of falling, and some scientists believe this will be the year we cross a dangerous climate threshold, the 1.5°C Paris Agreement goal, long before we (hopefully) achieve net-zero emissions in 2050.

Meanwhile, new guidance being piloted through the Science Based Targets... Read more
