The Thai government’s forthcoming “old car for new” program, aimed at accelerating electric vehicle (EV) adoption through subsidies and concessional loans, faces scrutiny amid questions about its overall effectiveness and beneficiary profile. Announced as part of broader efforts to advance the country’s transition to net zero emissions, the scheme is designed to incentivize consumers to trade in older vehicles for new EVs.

At the core of the initiative lies uncertainty over who will ultimately gain from the program. While the policy seeks to reduce fossil fuel consumption in Thailand’s transportation sector and bolster its domestic auto manufacturing industry—often dubbed the “Detroit of Asia”—critics highlight potential pitfalls regarding consumer benefits. With incentives routed via automakers, there is concern that price discounts could be absorbed upstream, diminishing the direct impact on buyers. This risk is especially significant given an already competitive EV market where prices have been pushed down aggressively.

Details of the scheme remain limited, but available reports indicate that the government intends to offer point-of-sale discounts along with loans up to 2 million baht at an interest rate of around 3.5%. However, this loan rate appears less attractive when compared with prevailing EV financing conditions, where rates as low as 0.01% to 1% are available. Economists and industry watchers warn that without mechanisms to prevent manufacturers from inflating prices before discounting, the program could distort market dynamics without truly benefiting consumers.

Beyond market considerations, environmental questions persist. Although replacing older internal combustion engine vehicles with EVs can lower tailpipe emissions, Thailand’s overall carbon footprint reduction hinges on complementary reforms in power generation and energy supply. Without a cleaner electricity grid, the net environmental benefits of increased EV adoption could remain limited. Additionally, the government has yet to clarify plans for managing the disposal of retired vehicles, obsolete EVs, and the batteries that will eventually reach the end of their lifecycle—issues critical to avoiding new forms of pollution.

The policy’s implementation framework also raises concerns. The criteria defining an “old car” eligible for trade-in have not been specified, and the scrappage process must be transparent to prevent vehicles from entering secondary markets, undermining the scheme’s objectives. Furthermore, although the initiative prioritizes domestically produced vehicles to anchor manufacturing investment in Thailand, the country’s EV ecosystem currently depends heavily on foreign technologies and supply chains. Observers caution that without investments to develop local capabilities and strengthen the domestic value chain, the policy might primarily stimulate vehicle sales rather than fostering sustainable industrial growth or reducing import reliance.

This is not Thailand’s first major effort to promote EVs. To date, subsidies have supported over 134,000 vehicles at a cost exceeding 19 billion baht, underscoring the government’s significant financial commitment. As further spending under the “old car for new” program looms, experts emphasize the importance of shifting focus from pure sales incentives to building a resilient, locally embedded EV industry that delivers broader economic and environmental benefits.

Ultimately, some analysts argue that taxpayer-funded policies must be rigorously evaluated based on value for money and clear public gains. If the advantages of the scheme disproportionately favor manufacturers rather than consumers or the environment, calls for policy reassessment may intensify.
