Green Building: Why The Built Environment?


We must eliminate all CO2 emissions from the built environment by 2040 to meet 1.5° Climate targets.

The Built Environment

The built environment generates 40% of annual global CO2 emissions. Of those total emissions, building operations are responsible for 27% annually, while building and infrastructure materials and construction (typically referred to as embodied carbon) are responsible for an additional 13% annually.

Green Building: Why Not Carbon Negative Concrete?

From Architect Magazine,

The imperative to reduce carbon emissions in the built environment is central to the Architecture 2030 Challenge.

Public and private sector research labs worldwide are racing to deliver carbon-reducing building materials. Chief among them: zero-carbon concrete.

Material scientists have made dramatic strides in recent years reimagining concrete composition and formulation. Commonly available manufacturing byproducts such as fly ash, bottom ash, slag, and other pozzolans are viable carbon emission-reducing replacements for traditional cement clinker.

Sacramento is at a tipping point. What’s the future of housing, sprawl and racial inequality?

By Ryan Lillis | June 12, 2023 | The Sacramento Bee

The Sacramento region is at a tipping point. And the next few years will determine what shape we leave it in for the next generation. The region’s housing is less expensive than California’s coastal cities, a selling point that motivated thousands of new residents to move inland since the start of the pandemic. Yet housing prices and rents have skyrocketed the past three years, and fewer than one-third of residents here can now afford to buy the median-priced home. Within the past few months, the Sacramento area became a “minority-majority” region, meaning white residents now make up less than 50% of the population. Still, substantial racial disparities in income, education and access to housing persist, even after the racial reckoning of 2020. Many commercial corridors remain starved for investment, especially those running through lower-income neighborhoods.

Sac leaders must advance work of Natomas Basin Conservancy, The Sacramento Bee, May 28, 2023

May 28, 2023

Brad Branan is a freelance journalist and photographer who sits on the boards of the Environmental Council of Sacramento and Sierra Club, Sacramento Group, both of which oppose development in the Natomas Basin.

One day, I saw a pair of Osprey build a nest atop a utility pole. Another day, I watched a Great Egret pluck aquatic creatures out of a canal and swallow them like popcorn shrimp. And on yet another day, I saw thousands of Snow Geese fly in unison near Highway 99, creating what looked like a vibrating cloud. The scenes happened on or next to property owned by the Natomas Basin Conservancy, a nonprofit organization that has collected fees from local governments and land donations from developers to protect threatened species since 1997. The Conservancy focuses on 22 plants and animals in the Natomas Basin, an area running from Garden Highway to south Sutter County, and from the Sacramento River to Steelhead Creek. Surveys have found that the Swainson’s Hawk, Giant Garter Snake and other threatened animals have maintained or increased populations during the Conservancy’s tenure. But now the Conservancy’s important work is under threat from three major development proposals
