The Supreme Court recently ruled against EPA, limiting its ability to regulate coal-fired power plants. But the news may not be as dire as it looks.

The U.S. Environmental Protection Agency (EPA) took a blow from the Supreme Court in late June when the court ruled against the Obama-era Clean Power Plan, which would... Read more

The Holy Grail of energy is for our buildings to go all electric and get that energy from renewable sources. The problem, of course, is what to do when the sun isn’t shining and the wind isn’t blowing. Batteries are the clear answer, and we already have lithium-ion-based systems that work well in electric cars and for building... Read more

It’s been decades since redlining—the federal government practice of refusing to guarantee loans in predominantly black neighborhoods—was outlawed in the U.S. But the impacts continue to ripple through formerly redlined neighborhoods, according to data released by LightBox, a geospatial data and software firm focused on the...

Forced labor, or modern slavery, is widely spread across the globe. People—including children—in forced-labor conditions work without pay or for recruitment fees, leaving them in debt bondage. Workers are threatened with relocation, deportation, and worse.

Nearly 25 million people are trapped in forced labor, according to the... Read more

We hear a lot about the sustainability commitments and plans of large architecture firms, but the reality is that the vast majority of firms—about 75% in 2019, according to research done by the American Institute of Architects (AIA)—are small (by their definition, “small” means ten or fewer employees). Although these small firms represent a... Read more

This program explains why increased forest protection and improved stewardship are key to addressing the climate crisis and reducing the embodied carbon of wood products — and how the green building movement can help.

For 25 years, Jason Grant has been a leader in the sustainable forestry and green building movements. He is the... Read more

Hardwood used for flooring can come from unsustainable sources, such as tropical forests and genetically engineered monoculture tree farms.

The availability of domestic hardwood from third-party FSC-certified forests makes this type of flooring a great option. Uncoated hardwood flooring does not require emissions testing, but... Read more

“It’s a huge opportunity, and we’d be crazy to miss it.”

Jonathan Klein, cofounder of the nonprofit UndauntedK12, wants building professionals to know they have a major role to play in transforming public education in the next three years. That’s because unprecedented federal funds are pouring into school districts, thanks to the... Read more

Unconstitutional. Draconian. Short sighted and dangerous.

That’s how a lawsuit brought by building owners describes New York City’s carbon caps for buildings—a.k.a. Local Law 97. The building performance standard (BPS) has yet to go into effect, but owners are already anticipating the fines they’ll have to pay come 2024, and some aren’t... Read more

What if you had a natural building material that could be grown from seed to harvest in three to four months, is good at sequestering carbon, requires no fertilizer, helps fix nitrogen in the soils, requires little water, can be grown on a small plot so it can replace more polluting and/or slower-growing materials such as...

Energy modeling and whole-building life-cycle assessment are sophisticated software for predicting the energy use and carbon footprint of a building. But often, these methods are used too late in design to make a difference. Now, a free online tool from architecture firm EHDD can help project teams home in on lower-carbon... Read more

When it comes to weighing sustainability, design, and comfort, few products have the challenges that carpet does. On the one hand, it is comfortable to walk on, it absorbs sound, and there are colors and patterns to complement nearly any design. But for all these positives, carpet has a history of containing potentially... Read more

Resilient flooring is often made from PVC, which BuildingGreen does not recommend due to potential life-cycle impacts. Once installed, emissions from frequent stripping and floor cycles can hurt indoor air quality.

There are a wide variety of acoustic materials that can be used to manage interior noise and help create a welcoming space. The acoustic wall and ceiling panels described here are typically part of a noise reduction strategy that incorporates carpet, acoustic ceiling tiles, and other interior products.
