Polluters want to delay clean air protections. Today, 99 Bay Area community members packed an meeting to say no. 🚫

Burning gas in homes and buildings generates more smog-forming NOx pollution than every passenger car in the Bay Area combined.

These standards help households upgrade to cleaner, more efficient electric appliances — better for your health, and better for your energy bills.

No delays. Tell : implement these rules with common-sense flexibility measures on time.

The smog isn’t just coming from traffic. It’s coming from our homes.

Gas-burning water heaters and furnaces produce more smog-forming pollution than all passenger cars in the Bay Area combined.

We already have clean air standards that can save lives. Now they need to be implemented.

Today, this message is featured in a full-page San Francisco Chronicle ad from the Bay Area Clean Air Coalition.

Tell don’t delay. Protect our air. Implement Rule 9-6. Take a look at the ad 👇 and help amplify!

🛥️ This week for Trail Thursday, we are featuring Angel Island State Park in San Francisco! There are no roads or bridges to get there, so you will have to take the ferry or your own boat.

🌊 The island has extensive history from being a seasonal hunting and gathering location for the Huimen tribe to becoming a U.S. immigration station processing thousands of people. You can learn more about its history at the museums in the park.

📍If you visit the park, tag us! We will be adding your pictures to future Trail Thursdays. If you have a trail recommendation, add it in the comments. We might feature it in the next Trail Thursday!

🥾 This week for Trail Thursday, we are featuring Mission Peak Regional Preserve in Fremont. The park is 3,023 acres and gets quite busy on the weekends so get there early!

🌄 The preserve features a magnificent view of the Bay Area at the peak. The trail to the top is recommended for conditioned hikers, but there are trails for every level at different areas of the preserve!

📍If you visit the park, tag us! We will be adding your pictures to future Trail Thursdays. If you have a trail recommendation, add it in the comments. We might feature it in the next Trail Thursday!

AI-powered platforms are being used to submit fake comments opposing clean air rules — and California’s democratic process is paying the price.

A new investigation finds an industry front group, Common Sense Coalition, used AI platform Speak4 to submit fake public comments to Bay Area Air District regulators in real residents’ names — without their knowledge or consent. At least 10 residents confirmed they never authorized the emails.

This follows reporter Hayley Smith’s investigation finding that 20,000+ AI-generated comments flooded the South Coast Air Quality Management District before critical clean air rules were voted down — rules that would have prevented thousands of premature deaths and asthma cases across Southern California. When SCAQMD’s cybersecurity team contacted a small sample of the commenters to verify, a majority of respondents said that they had not submitted the comments in their names.

This is a statewide pattern. And Sacramento is responding: Sen. Christopher Cabaldon has introduced SB 1159 — “People, Not Bots” — to clarify that AI systems are not “persons” under California’s public comment and transparency laws.

But new legislation alone isn’t enough. Community leaders are calling on to investigate who is behind these campaigns, how many identities were used without consent, and whether California law was broken.

Share this post! Public participation should reflect real communities — not manufactured opposition.

⛰️ This week for Trail Thursday, we are featuring Big Basin Redwoods State Park in the Santa Cruz Mountains. The park is California’s oldest state park!

🌲 In 2020, the park faced a devastating wildfire. While many of the old-growth redwoods survived, the fire still radically changed the park’s landscape. The park’s rebuilding is being overseen by the Reimagining Big Basin Project!

📍If you visit the park, tag us! We will be adding your pictures to future Trail Thursdays. If you have a trail recommendation, add it in the comments. We might feature it in the next Trail Thursday!
