Thailand improves environmental index: A step towards more sustainability!
On October 22, 2025, the Thai Ministry of Natural Resources and Environment (MoNRE) presented the results of the Environmental Performance Index (EPI) for Thailand. The overall score has increased to 75.7 points, which represents a pleasing increase of 74.4 points in 2024. This positive development reflects advances in natural resource management and environmental protection, which are evident in various areas.
The detailed analysis shows the following scores: Environmental health achieved 57.2 points, while Thailand achieved an impressive 95.6 points in the area of climate change. The score for the integrity of the ecosystems is 66.4 points. The PPI Thailand serves as an important macroeconomic indicator and can be compared to the Gross Domestic Product (GDP) and the Social Progress Index (SPI). This is also reinforced by the country's commitment to implementing various measures to improve the EPI score since 2022.
Developments and measures
A key element of the EPI improvements is the integration of data, which was promoted through the signing of memoranda of understanding (MOU) with nine ministries and 24 agencies. Transparency has also been improved by improving data reporting on the website epi.onep.go.th increased. Guidelines have also been developed to make the management of natural resources more efficient.
However, the challenges do not remain. To further raise the score, issues such as reducing PM2.5 exposure, loss of forest land and improving wastewater treatment need to be addressed more intensively. A central goal is to sustainably improve environmental quality and the population's standard of living.
Positioning internationally
The current assessment of climate policy in Thailand is rather mixed. The country ranks 24th in the Climate Change Performance Index (CCPI). While the performance in terms of greenhouse gas emissions is rated high, the renewable energy policy is rated as “very low”, according to experts. However, a new approach is on the horizon: Thailand is finalizing its first climate protection law, which will provide the legal framework for carbon pricing mechanisms.
Back to nature and new technologies
The new climate protection law aims to achieve carbon neutrality by 2050 and net zero emissions by 2065. Implementing a carbon tax and emissions trading system could help Thailand meet Paris Agreement commitments. Experts hope these measures will strengthen investor confidence and promote private investment in cleaner technologies.
In addition, new incentives such as subsidies for electric vehicles (EVs) will see increasing sales figures, with sales of 80,000 units last year. This corresponds to around 10% of all new car sales. Such measures are necessary given the challenges in the energy sector, which is considered the largest contributor to greenhouse gas emissions.
The positive development of recent years shows that Thailand is on the right track when it comes to asserting its place in global environmental policy. With a clear focus on sustainable energy and more comprehensive environmental protection, the country could achieve its goals while providing its citizens with a better quality of life.
