Mayor Lori Lightfoot was scheduled to release Chicago's long-awaited Climate Action Plan last week on Earth Day.

• But undisclosed delays halted the release, leaving Lightfoot to unveil just four pillars instead.
• Her office said to expect the actual plan in "coming weeks."

Why it matters: Cities create about 75% of the world's CO2 emissions, according to the UN — and that makes municipal climate action plans with accountable goals a big deal.

• Plus, Lightfoot campaigned on climate action, and we've seen little so far.

Yes, but: On Friday, Chicago Public Schools did release a Climate Action Plan for its district of 330,000 students, 630 schools and 64 million square feet of facilities. It includes installing solar panels on its buildings for saving energy and teaching students about solar power. Its goals:

• Reducing electricity consumption by 30% from the 2019 baseline by 2025.
• Decreasing natural gas consumption by 20% by 2025.
• Moving to 100% renewable electricity sources by 2025.
• Reducing greenhouse gas emissions by 45% by 2030.
• Reaching an 80% waste diversion rate by 2030.

What's next: Axios looks forward to Lightfoot's citywide plan. In the meantime, we hope to see updates on outside climate commitments that Chicago signed on to, including:

• Reducing greenhouse gas emissions in Cook and the collar counties by 80% from 2005 levels by 2050, as part of the Metropolitan Mayors Caucus regional plan.
• Decreasing Chicago's carbon emissions by about 25% from 2005 levels by 2025 as part of Paris agreement commitments signed by Mayor Rahm Emanuel in 2017.
• Powering all Chicago buildings with renewable energy by 2035 as part of an Emanuel commitment.

Chicago's Jam Productions is celebrating 50 years of being an independent live concert company — but a new partnership may change the way the company tackles the next 50.

Why it matters: Jam is teaming up with the national live music network SaveLive, created in 2020 by Lollapalooza co-founder Marc Geiger to bail out promoters and venues that struggled during the pandemic.

• "It has been obvious that for Jam’s business to grow, it needed to be part of a network," owner Jerry Mickelson said in a press release.

Context: Jam is one of the largest independent live entertainment producers in the country. They own several venues, including Park West and the Vic.

• "For the past two decades, Jam has been fighting a lonely battle against the corporate monopoly of Live Nation/Ticketmaster, the most destructive force in the music industry," music journalist and co-host of "Sound Opinions" Jim DeRogatis tells Axios.
• "Will being part of a competing national network be an improvement? That remains to be seen."

💭 Justin's thought bubble: The pandemic stretched so many independent venues to the brink of closure. It's nice to see Jam get some support. I just hope it continues to keep Chicago's indie spirit alive. And that ticket prices don't go up.

👋 Hey, it's Monica.

Last week, the Chicago Tribune's Nick Kindelsperger declared the Cuban sandwiches at TriBecca's Sandwich Shop "jaw-droppingly gorgeous," so naturally I zipped over to the Avondale shop for a try.

• Their Cuban ($12.95) delivered a fine, hefty Midwest take on the porky, pickly pressed sandwich, but what really caught my eye was the "loaded baked potato-nut" ($4.95).

What is it? A savory doughnut using Illinois potatoes in dough fried in clarified butter. The fluffy fritter is then topped with sour cream, bacon, chives and cotija cheese.

Other winners: The MaidWrong loose-meat sandwich ($11.95), which my son declared a "Philly cheesesteak on brioche."

• The Crispy "Frosted" Cauliflower sandwich ($12.95), a chicken sandwich without chicken.
• The decadent Horseshoe Sandwich ($12.95), featuring rich cheesy sauce over crinkle fries and two patties of local beef. Also available with tofu.

Keep in mind: TriBecca's (run by former Sunday Dinner Club cook Becca Grothe) is closed Tuesdays and Wednesdays.

After months of waiting for the weather and/or COVID to let up, we're returning to the Hideout porch stage this Thursday at 6pm for Axios Office Hours.

We'll talk to…

• Natalie Moore about her new book and play called "The Billboard."
• Abby McEnany about her television show "Work in Progress" and what's next.
• WTTW's Geoffrey Baer about "The Great Chicago Quiz Show."

The deets: This is an outdoor event under a tent, so dress appropriately.

• And we'll have Axios swag for those who have won contests in the past!

If you go: RSVP for the free show so we know how many people to expect.

The weekend's glorious weather brought out the Jackson Park cherry blossoms and loads of visitors. You can still catch them this week.
