21 Dec 20256 min read
Summary
- Southeast Asia’s cities are expanding at unprecedented speed, driving economic growth while significantly increasing energy use and carbon emissions from the built environment. With buildings and construction accounting for a large share of global emissions, the region’s ability to build resilient, low-carbon cities will shape its long-term sustainability and competitiveness.
- While government policies and regional pledges are important, investor pressure, consumer demand, and ESG reporting requirements are increasingly driving sustainability in urban development. Developers, building owners, and occupiers are now jointly responsible for emissions performance, making sustainability a shared ecosystem-wide obligation rather than a niche initiative.
- Smart technologies, real-time monitoring, AI-driven optimisation, and verified Renewable Energy Certificates are enabling transparency, traceability, and measurable emissions reduction. Platforms like GoNetZero™ demonstrate how integrating digital tools with renewable energy verification can turn sustainability commitments into verifiable impact, supporting Southeast Asia’s transition toward sustainable, future-ready cities.
At the 8th ASEAN Smart Cities Network Annual Meeting held in September 2025, the ASEAN Smart City Action Plan outlined strategic frameworks to guide member states in transforming cities into greener, more inclusive, and digitally-empowered urban spaces. This reflects a growing recognition that the cities powering Southeast Asia’s economic growth will also determine their ability to decarbonise and build long-term resilience, an increasingly urgent vision given the region’s rapid urbanisation pace. According to the United Nations Human Settlements Programme, Asia’s urban population is projected to grow by 50% to an additional 1.2 billion by 2050, of which more than half of Southeast Asia’s population is living in urban areas and expected to reach 65% by 2050. This rapid urbanisation brings both opportunity and urgency. The built environment already contributes more than one-third of global energy-related carbon emissions. In 2022, building operations generated three gigatonnes (Gt) of direct carbon dioxide (CO₂), and 6.8Gt of indirect emissions from electricity and heat generation, while construction added another 2.5Gt.Across the region, innovation is accelerating. Singapore has established itself as a leader in smart citizen services and digital infrastructure. Meanwhile, the International Monetary Fund forecasts Indonesia to be one of the region's fastest growing markets, driven by large-scale urban development such as the building of its new capital city, Nusantara. Such projects create fertile ground for innovation, as they demand new approaches to infrastructure, sustainability, and technology integration. As cities expand, the question is no longer whether to decarbonise but how to do so credibly, verifiably, and at the scale required to shape a sustainable future.
Reshaping sustainability in the built environment sector
Southeast Asia’s infrastructure expansion has fuelled economic growth but also increased its vulnerability to climate change, making it one of the world’s most at-risk regions. The built environment plays a central role, of which operations and construction materials together account for approximately 37% of global energy-related emissions. In response, governments across the region are implementing new regulations and sustainability standards for the sector. In response, governments across the region are implementing new regulations and sustainability standards for the sector.These regional efforts align with a growing push for sustainability. At COP28, Southeast Asian countries such as Singapore, Malaysia, and Thailand signed the Global Renewables and Energy Efficiency Pledge, reaffirming their commitment to decarbonisation and renewable energy integration. National-level initiatives further reflect this commitment. Singapore, for instance, has set a goal under its Green Plan to have at least 80% of its buildings green by 2030. Similarly, Vietnam has set and surpassed its target to construct 150 green buildings by 2030 under its National Energy Efficiency Programme. However, progress across the region remains uneven. In Thailand and the Philippines, political, economic, and institutional constraints continue to hinder the wider uptake of green buildings. A persistent lack of political will, shaped by instability and a heavy emphasis on infrastructure expansion, such as the Philippines’ 'Build Better More’ programme has sidelined sustainability considerations. Frequent policy shifts and economic uncertainty have further pushed sustainability down the agenda in these markets.
Market momentum and the environmental, social, and governance imperative
Regulation alone is not sufficient as a driving force to transform the region’s built environment. While market forces are accelerating the region’s shift towards decarbonisation in the sector, consumer sentiment is notably shaping the nature of urban developments. A survey by Singapore’s Building and Construction Authority found that 83% of property agents observed developers pivoting towards green projects, and more than half of Singaporeans were willing to pay a 3% to 4% premium for homes in certified sustainable buildings.At the same time, investors are raising expectations. While there has been pushback against Environmental, Social and Governance (ESG) efforts in the United States, global regulatory momentum remains strong. For example, the European Union (EU)’s Corporate Sustainability Reporting Directive sets mandatory disclosure requirements, compelling investors to stay aligned with ESG goals regardless of local sentiment. Although the EU’s recent ‘Stop the Clock’ directive has delayed reporting timelines for some large companies, it reflects a recalibration rather than a reversal, signalling that the regulatory direction is intact, even if the pace varies. These expectations are now extending beyond corporates to include building owners, asset managers, and tenants, who are increasingly being held accountable for their Scope 1 and Scope 2 emissions. Sustainability is no longer a developer-led initiative. It is a shared responsibility across the built environment ecosystem. Stakeholders, from investors to occupiers, must view ESG not as a siloed goal, but as an integral part of long-term business and societal value.
Planning for greener, cleaner infrastructure
As sustainability evolves from a compliance checkbox to a critical lever for innovation, trust, and growth, the built environment sector must embed low-carbon planning from the outset. Integrating sustainability at the design stage allows for measurable carbon reduction, preventing costly retrofits to meet future standards. From material selection to the decarbonisation strategies, early integration delivers long-term efficiency and significant cost savings across a building’s lifecycle. According to the Organisation for Economic Co-operation and Development, strategies such as improving building envelopes, optimising energy systems, and increasing renewable energy utilisation are critical for reducing CO₂ emissions.This highlights the importance of early foresight, including multiple decarbonisation pathways, and leveraging digital technologies to accelerate sustainable progress.
Smart technologies for effective decarbonisation
Developers, building owners, and facility managers are increasingly turning to digital solutions to ensure transparency, traceability, and long-term carbon reduction. Digital technologies are pivotal in two areas – real-time performance monitoring and energy source traceability.Accurate, real-time monitoring helps quantify energy efficiency and track emissions across portfolios. It enables facility managers to detect inefficiencies and respond dynamically to changes in occupancy, weather, and demand, allowing operational emissions to be reduced by up to 42%.Artificial intelligence can further enhance traceability and performance. They can pinpoint inefficiencies across both new and existing infrastructure, enable rapid optimisation, and improve energy management while reducing emissions.
Turning renewable claims into proof with verified RECs
Beyond monitoring, Renewable Energy Certificates (RECs) have become a critical step in strengthening the integrity of decarbonisation claims, as well as mitigating greenwashing risks and enhancing transparency across the energy value chain. While the voluntary carbon market continues to mature, verified RECs remain essential for addressing Scope 2 emissions and enabling corporates to demonstrate credible renewable energy use. Cross-sector collaboration on digital innovation will be key to scaling such verification and accelerating long-term decarbonisation across the region.Companies such as GoNetZero™ are enabling this shift through comprehensive solutions that integrate verified RECs and emissions data in a single integrated ecosystem. By enabling verifiable renewable certificate sourcing and transparent reporting, these solutions help organisations progress from intention to impact, aligning operational performance with net-zero commitments.
Laying the path forward
Southeast Asia’s urbanisation and smart city investments will continue to accelerate. To stay ahead of the curve, the built environment sector must align with rising environmental expectations and embed transparency into every layer of value creation. To transform sustainability from compliance to competitive advantage, businesses must harness digital tools, energy-efficient design, and renewable technologies to achieve verifiable impact, driving the region’s transition towards a truly sustainable urban future.
