🗞️ Good morning! When it rained last Sunday, photojournalists from The Standard and ThaiRath captured images of rats fleeing flooded drains for higher ground. A Din Daeng cafe lets visitors look into the world of ants.

That’s the cigarettes equivalent of pollution Bangkok residents breathed in 2025, according to Rocket Media Lab’s analysis. Meanwhile, the city claimed it cut PM 2.5 levels by 50%.

Why it matters: Bangkok had only 38 good air quality days in 2025, down from 43 the year before. Most days fell in the “moderate” range, according to the World Air Quality Project.

Zooming in: A PM 2.5 reading of 22 micrograms per cubic meter equals one cigarette. Bangkok averaged above that threshold for most of 2025.

Flashback: Then-Gov. Chadchart Sittipunt said his administration halved pollution levels between December 2025 and February 2026, compared with the same period the year before.

Yes, but… Data from the World Air Quality Project shows only a 1.14% reduction.

Bangkok’s problems now have a new answer on the campaign trail: AI.

Why it matters: Bangkok already has the data infrastructure to support it, including Traffy Fondue, open data portals and a growing CCTV network.

Driving the news: These AI proposals cluster around the same problems: traffic, floods and corruption.

The catch: These aren’t new promises. Bangkok governor campaigns have run on fixing floods, traffic and corruption in virtually every election cycle since 1985 with limited success. The difference this time is the tool they’re reaching for.

Zooming out: Experts said the success of AI-driven plans depends on strong data governance and safeguards against algorithmic bias and legal risks. They recommended an AI ethics committee for oversight.

State of play: The Chadchart administration made 1,442 datasets public. More than 53,000 entries are also available on the Bangkok Open Contract, which publishes procurement and budget data.

Yes, but… Challengers say budget documents still arrive as unextractable PDFs, records still sit on paper, and datasets still don’t connect. Making existing data machine-readable is their priority.

Less than two months after it was announced, the deputy transport minister said the 40-baht all-day electric train fare cap is “entirely scrapped,” citing subsidy costs and negotiations with operators.

Why it matters: It was a flagship Bhumjaithai cost-of-living pledge. As recently as the announcement, officials said it would take effect on Jan. 1, 2027.

The intrigue: Transport Minister Phiphat Ratchakitprakarn later contradicted his deputy, saying the plan isn’t scrapped — just delayed.

State of play: A unified fare requires single ownership, which the government doesn’t have. A new proposal that would go before the Cabinet this week would set a 17-45 baht per-trip fare, with the 40-baht cap retained only for the state-run Red and Purple lines.

Flashback: Soiciety reported in April that the plan faced long odds from the start. It required 97 secondary regulations and concession buybacks from private operators — negotiations that hadn’t begun.

Bangkok’s electric train network has grown from two to 10 lines since 1999, covering 275 kilometers, according to The Active. But the expansion has mostly served the same areas.

Why it matters: Thirteen of the city’s 50 districts have no train station at all — most are residential outer districts like Bang Khun Thian, Nong Chok and Thong Khru. The five districts with the most stations are all in the inner economic core.

Zooming in: Bus routes reach more districts than trains, but the districts with the fewest routes are the most populated.

The bottom line: A Thailand Development Research Institute researcher said the missing piece is connectivity. He said better sidewalks, bus-to-train links and feeder services in narrow sois are what would get people out of their cars.

Critics and election challengers have accused the Chadchart administration of selling district director positions for up to 4 million baht each — an allegation Chadchart and his team deny. No formal complaint has been filed.

Why it matters: District directors run the 50 district offices that handle everyday services such as issuing permits and inspecting sites. The allegations landed mid-governor’s race.

Flashback: The city’s Merit System Protection Commission last year voided 17 district director appointments for procedural irregularities. It’s the only formal finding related to the matter so far.

The pushback: Chadchart challenged critics to produce evidence. More than 20 district directors rejected the claims as politically motivated and said they were considering legal action.

Zooming out: In a December 2025 NIDA poll, 46% of Bangkok voters said corruption was handled “not well” or “not well at all” under Chadchart’s tenure.
