As the global business landscape pivots towards sustainability, The Siam Cement Public Company Limited (SCG), one of ASEAN’s largest and most diversified conglomerates, is placing environmental, social and governance (ESG) principles at the heart of its corporate strategy. With operations spanning Thailand and nearly every major ASEAN market, SCG is setting an ambitious course to achieve sustainable growth while positioning itself as a regional ESG leader.
Against a backdrop of mounting economic uncertainty, climate volatility and shifting geopolitical dynamics, SCG convened the ESG Symposium 2025, which has emerged as a pivotal platform uniting government, business and civil society to accelerate Thailand’s transition towards a low-carbon economy. Under the theme ‘Green Breakthrough Amid the Perfect Storm: Accelerating with Green, Surviving Together’, the symposium presented a bold agenda designed to be competitive, inclusive and actionable.
The forum gathered more than 300 participants from government, the private sector and civil society, both in Thailand and abroad, to exchange perspectives and solutions on accelerating the green transition.
The 13th edition of the symposium focused on three key agendas:
Accelerating the transition to clean energy.
Enabling SMEs to move towards a just and inclusive low-carbon business model.
Preparing to cope with climate uncertainty while enhancing national competitiveness.
On 2 October 2025, at the Talk Stage, Hall 4, Ground Floor, Queen Sirikit National Convention Centre (QSNCC), SCG presented the updated outcomes of the ESG Symposium 2025.
SCG Calls for Urgent Energy Reform
Delivering opening remarks, Thammasak Sethaudom, President and CEO of SCG, emphasised that structural shifts such as energy transition must be initiated as early as possible. He unveiled SCG’s Future Bangkok simulation, which illustrates the risks of land subsidence, rising sea levels and tectonic shifts affecting the capital.
‘ESG Symposium is more than dialogue; it is a platform to design and drive solutions that keep Thailand competitive and sustainable. We want to be a platform where people come together, share knowledge and mobilise ideas to co-create solutions,’ said Mr Thammasak.
He also underlined the urgent need for structural reforms to unlock liberalised energy markets, promote clean energy at affordable costs and strengthen infrastructure against climate risks.
Key proposals included implementing the Third Party Access (TPA) Code to open the electricity market, expanding Direct PPA contracts to encourage renewable investment, and leveraging advanced technologies such as energy storage and hydrogen to support grid stability.
Thailand’s vulnerability to droughts, floods and climate-driven resource disruptions has made climate adaptation a national priority. The symposium underscored the need for integrated action, linking policy, technology and community knowledge to build long-term resilience.
Despite Thailand’s climate ambitions, experts voiced concerns over the pace of change. ‘Thailand’s energy system faces mounting pressure from Nationally Determined Contribution (NDC) 3.0 commitments, the EU’s CBAM and the need to raise its Energy Transition Index. We must pursue a clear, agile and actionable roadmap,’ said Dr Areeporn Asawinpongphan, Research Fellow – Energy Policy at the Thailand Development Research Institute (TDRI).
She also stressed that Thailand still lacks a 2030 renewable energy generation target, with the current goal only set for 2037. At present, clean energy accounts for about 15% of national energy consumption.
She added that while Thailand’s Net Zero goal is currently set for 2065, ten years behind neighbouring countries, the new government has indicated plans to advance the target to 2055. Achieving this, she noted, would require clean energy adoption to reach 40% by 2030.
To accelerate the transition, TDRI proposed a three-phase roadmap. In the short term, it recommended reviewing electricity tariffs to reflect actual costs, expanding grid connectivity rights, promoting renewable electricity trading, establishing ‘green fast-track’ channels and reducing unnecessary regulations. In the medium term, the focus should be on announcing and implementing an updated Power Development Plan while strengthening energy security. In the long term, the clean energy roadmap should be aligned with national economic and social development strategies, with policies tested and refined in real-world contexts.
Dr Areeporn highlighted that a faster transition would reduce industrial costs, minimise cross-border carbon adjustment taxes and sustain Thailand’s economic competitiveness, while also enhancing investment attractiveness. She stressed the importance of transparent renewable energy markets, modernised tariff structures and skill-building for a green workforce.
SMEs Central to Thailand’s Green Competitiveness
SMEs remain the backbone of Thailand’s economy, representing 99.5% of enterprises and employing more than 13 million people. However, they continue to face challenges in financing, market access, regulatory complexity and skills development.
Another focal point of the symposium was supporting micro, small and medium enterprises (MSMEs) in their green transition journey. Dr Noppong Teeravorn, President of the Federation of Thai SME, emphasised that Thailand hosts more than 2.7 million micro-enterprises employing 5.5 million people, yet most lack access to finance, future skills and new market opportunities.
‘Micro, small and medium-sized enterprises are central to Thailand’s future competitiveness, but they need real support to thrive,’ he said.
He outlined solutions such as low-interest microfunds (3-4% per annum), digital and green skills training, and the creation of One Stop Service centres to connect SMEs with funding, innovation and global markets. These measures, combined with policy reform, aim to transform SMEs into a powerful driver of sustainable and inclusive economic growth.
‘MSMEs face constraints in funding, capacity building and regulatory barriers. Without targeted support, many risk being left behind in the green economy,’ said Dr Noppong.
The symposium proposed three phases of MSME development support. In the short term, it called for expanding access to funding, raising product standards and enhancing differentiation. In the medium term, the focus should be on building knowledge and skills aligned with the energy transition while encouraging business clustering. In the long term, reforms are needed to remove regulations that hinder fair competition for MSMEs.
SCG pledged to leverage its role as an industry leader to share knowledge and data resources, creating opportunities for smaller enterprises to benefit from its scale and experience.
As a concrete step forward, SCG also announced plans to advance Public-Private Partnership pilot projects, beginning with the Saraburi Sandbox, which integrates low-carbon industrial practices, renewable energy and circular economy models.
‘SCG alone cannot drive transformation. It requires collective effort across sectors. Our role is to open the platform, share what we know and help mobilise every stakeholder,’ Mr Thammasak reiterated.
