It’s Net Zero Buildings Week, which makes it a great time to celebrate building decarbonization and electrification efforts across California!

While buildings contribute about 25% of California’s total greenhouse gas emissions, there have recently been major strides to bring this number down: over 50 jurisdictions have formally committed to decarbonizing new homes, and just last year, the California Energy Commission approved AB 3232 and the California Building Decarbonization Assessment to reduce 40% of building emissions by 2030. Additionally, California’s 2022-2023 state budget has allocated nearly $1 billion for retrofitting older buildings, and four California cities have joined the National Building Performance Standards Coalition to advance innovative, equitable approaches to decarbonizing existing buildings.

These efforts are important steps toward making homes healthier for occupants and their communities, and Build It Green has been bringing together decisionmakers, builders, designers, and advocates across California to keep the momentum going. We invite you to check out the work compiled below, which highlights the power of this collaboration and offers approaches we can take to support affordability and social equity goals on the way to a net zero future. We hope you’ll spend some time diving in!
