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.

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

The EPA is finalizing rules that make it easier to find where and how PFAS are being used, making it easier to regulate them in the future.

November 6, 2023

PFAS (per- and polyfluoroalkyl substances), forever chemicals, are one of the biggest environmental challenges facing the world today. There are more than 10,000 PFAS, some of which are persistent, bioaccumulative toxic chemicals. So why don’t we just ban products that use them?

That’s hard when you don’t know which PFAS are being used... Read more

Lofty net-zero commitments and fledgling ESG programs typically lack realistic implementation plans. USGBC wants to fill the gap—but not with LEED.

November 6, 2023

The organization that created LEED is now advancing a whole new certification concept—one that doesn’t start with an L for leadership.

Also, only existing building portfolios need apply. And the U.S. Green Building Council (USGBC) Portfolio Accelerator, which is still under development but is due out in 2024, will have no points and no... Read more
