Monday morning in Bangkok saw renewed debate around the environmental footprint of Thailand’s rapidly multiplying artificial intelligence (AI) data centers. During today’s session, opposition MP Chatchai Phromlert urged the National Assembly to establish a specialized committee focused on scrutinizing the sector’s resource consumption, as major approvals for new data center projects continue to make headlines.
Thailand’s central plains are experiencing their hottest July on record, intensifying concerns about water and electricity use by data centers, which are estimated to require millions of liters of cooling water and up to 100 megawatts of power per site. These figures, referenced by the Ministry of Digital Economy and Society last week, have drawn attention from local NGOs, who note that Bangkok’s northern districts have already seen a 14% uptick in energy demand since April 2026 due to new tech infrastructure.
The government’s digital transformation agenda, which targets a 30% increase in domestic data processing capacity by the end of 2026, is a key driver behind the surge in AI data center construction. However, Chatchai warned of “limited oversight” and called for public disclosure of environmental impact assessments (EIAs) for all new projects. While the Digital Economy Promotion Agency (DEPA) has pledged to develop sector guidelines, no binding regulations have been enacted to date.
Industry leaders, including executives from Siam Data Park, maintain that their upcoming facilities will prioritize green certification and water recycling systems. However, independent analysts point out that voluntary commitments lack enforceable targets and that most projects remain in early planning or construction stages, making meaningful environmental progress difficult to verify this summer.
With the parliamentary session set to continue later this week, and a record-breaking heatwave putting utility capacity in the spotlight, the issue is expected to remain high on both the legislative and public agenda throughout July and August 2026.
