D.C.'s denser, more transit-friendly neighborhoods such as Navy Yard tend to have lower carbon emissions than largely single-family neighborhoods like Palisades, according to new research.

Why it matters: The data shows that planet-warming emissions can be reduced by both leadership decisions — such as building more housing near public transportation — and personal lifestyle choices like driving an electric car or cutting down on air travel.

What they did: With help from consulting firm EcoDataLab, researchers at the University of California, Berkeley measured household CO2 emissions by analyzing transportation, housing, foods, goods — like furniture and appliances — and services — like education and health care.

• The New York Times then turned that data into an interactive map:

Zoom in: In Northern Virginia, carbon emissions in the low-density, affluent Great Falls area are much higher than the national average across all five categories.

• In contrast, urban parts of Arlington along Metro corridors have emissions equal to or below the national average.

The big picture: The Metropolitan Washington Council of Governments has a goal of reducing greenhouse gas emissions by 50% by 2030. It exceeded its 20% reduction goal in 2020.

• Further progress will require more solar power and net-zero energy buildings, and increased opportunities for transit, teleworking, walking, and bicycling, according to the group.

Hey, Paige here with the toughest assignment (😉) I've had to date: ranking D.C.’s top food halls. 

Why it matters: Our region has seen an influx of food halls over the years. It’s hard to figure out which ones are worth a trip, so I did the heavy lifting for you. 

Methodology: I considered ordering methods, unique food options, seating, ambience, and vendor variety. 

1. The Roost

The Capitol Hill food hall opened in 2020. It snagged our top spot because it's perfected the classics from burgers to tacos — everything I tried was truly delicious. Plus, it has great variety without too many options. 

Must-try: Taco Night in America (beef, queso, pico) from Hi/Fi Taco.

For a quick bite: Grab a funfetti cookie from Cameo.

Bonus: There’s a Shop Made In DC inside.

Address: 1401 Pennsylvania Ave. SE

2. Union Market

Yes, I know, you’re surprised to see Union Market take second place. It is a fantastic food hall that represents so many different food traditions, but for those of us who get overwhelmed by lots of options (🙋🏾‍♀️) it’s not the easiest to navigate. Plus, the ordering systems and seating options could use some improvement.

Must try: Puddin’s bread pudding. Even if you think you’re not a fan, this rendition will change your mind.

Always a hit: Bun’d Up. The gua bao with a Taiwanese twist never disappoints. 

Address: 1309 5th St. NE

3. The Block (Annandale)

The Block is Asian fusion heaven. It has three locations all with different vendors, but Annandale has great variety. 

• It feels intimate without being cramped. The perfect spot to share a cozy meal with good friends. 

Must-try: Fried chicken tacos served on roti canai flatbread from Balô Kitchen.

Sweet tooth: Choose your own adventure at SnoCream Company with dozens of toppings and treats to add to their specialty ice cream/shaved ice hybrid. 

Address: 4221 John Marr Dr., Annandale

Instead of a white Christmas, expect the coldest one in decades. An Arctic blast is forecasted to bring frigid temps and strong to potentially damaging winds of 40-50 mph on Friday.

• Christmas Day will be sunny and breezy with a high of 28 and lows in the teens, per the National Weather Service.

🧊 Threat level: The bitter cold sweeping across the lower 48 states (and D.C.) will impact holiday travel, Axios’ Andrew Freedman writes.

• The combination of bitterly cold temperatures and a powerful storm system could halt pre-Christmas travel across the Ohio Valley and the rest of the Midwest, the NWS warned.

Public school enrollment in our region has dipped since 2019, especially in suburban school districts.

Why it matters: The declines might be caused by decreased demand for public schools during the pandemic and lower birth rates, per the D.C. Policy Center.

By the numbers: Fairfax County saw the largest enrollment decline of 4.7% between 2019 and 2022. Arlington County schools saw a smaller 2% decrease.

Yes, but: Public school enrollment is slowly inching back toward pre-pandemic levels, but has yet to make a full recovery, per data from local school officials.

• Enrollment gains for the 2022-2023 DCPS school year were the highest since before the pandemic.
