Beyond Ambition: Bridging Indonesia’s Sustainability Implementation Gap, Reflections from ISF 2026
The Indonesia International Sustainability Forum (ISF) 2026, held on 6–7 October 2026, brought together policymakers, industry leaders, financial institutions, think thanks, and sustainability practitioners to discuss Indonesia's evolving green economy and energy transition.
Throughout the forum, Mt. Stonegate team participated in discussions on energy security, corporate renewable electricity procurement, industrial decarbonization, and carbon market development.
While the forum highlighted encouraging momentum in Indonesia's sustainability agenda, it also reinforced a critical observation: ambitious commitments and policy frameworks alone are not enough. The real measure of progress lies in whether these ambitions can translate into practical, commercially viable outcomes.
Corporate Renewable Energy Demand Is Established, but Can the Market Deliver?
One of the most significant discussions at ISF 2026 centered on the growing influence of corporate electricity demand in shaping Indonesia's renewable energy transition.
A notable milestone was the announcement of APP Group joining RE100 as its first Indonesia-headquartered member, signaling stronger domestic corporate participation in international renewable electricity commitments. However, corporate demand is not a future prospect. It is already substantial.
According to Climate Group's RE100 2025 Annual Disclosure Report, published in September 2026, 147 RE100 member companies operating in Indonesia reported approximately 3.1 TWh of annual electricity consumption, yet only 35% was recognized as renewable electricity under RE100's criteria. These figures underline an important distinction: while corporate renewable energy commitments are growing, measurable progress toward fulfilling them remains uneven.
During the session How Corporate Demand Can Shape Indonesia's Green Power Transition, WRI Indonesia highlighted a growing preference among corporate buyers for more diverse renewable electricity procurement mechanisms, particularly direct contracts with renewable energy generators rather than relying exclusively on unbundled Renewable Energy Certificates (RECs).
RECs continue to play an important role in corporate renewable electricity procurement. However, companies increasingly require greater flexibility to combine different solutions, including on-site renewable generation, direct electricity contracting, and credible certificate-based procurement.
From Mt. Stonegate's perspective, encouraging corporate commitments is no longer sufficient. Indonesia must develop an electricity market that enables businesses to act on those commitments. Without accessible procurement options, predictable regulatory mechanisms, and commercially competitive renewable electricity supply, corporate demand alone will not deliver the scale of transition Indonesia seeks.
The challenge is therefore not simply creating demand, but ensuring that the market can respond to it.
Industrial Decarbonization: Closing the Gap Between Policy and Delivery
Industrial decarbonization was another prominent topic at ISF 2026, particularly in discussions examining how Indonesia can strengthen its competitiveness within an increasingly low-carbon global economy.
Indonesia Climate and Growth Dialogue (ICGD) presented its policy brief, Anchoring the Delivery Enabler for Green Industrial Competitiveness, which raised an important distinction: Indonesia's industrial decarbonization challenge is fundamentally a delivery gap rather than a policy gap.
The brief identified access to affordable clean energy as a recurring constraint across industrial sectors, alongside fragmented institutional coordination, project preparation challenges, and difficulties connecting available financing with commercially viable investments.
This raises a critical question: If the policy direction is already established, what is preventing industrial decarbonization projects from reaching implementation?
For businesses, decarbonization is not simply a matter of adopting sustainability targets. It requires decisions involving energy costs, infrastructure investments, technology upgrades, and long-term operational competitiveness.
From Mt. Stonegate's perspective, industrial decarbonization must be approached as a commercially viable transformation rather than merely a compliance exercise. Clear implementation roadmaps, accessible renewable energy solutions, credible emissions accounting, and investment-ready projects are essential to closing this gap.
As international supply chains increasingly prioritize lower-carbon production, Indonesia's competitiveness will depend on its ability to turn industrial decarbonization ambitions into measurable, operational improvements.
Carbon Markets: Regulatory Progress Must Translate into Market Confidence
Another important development at ISF 2026 was the discussion surrounding Indonesia's evolving carbon market framework and its preparations toward COP31.
During the session Indonesia's High-Integrity Carbon Market: Implementation Update and the Road to COP31, government representatives outlined regulatory developments covering compliance and voluntary carbon markets, Article 6 mechanisms, and additional implementing regulations.
These developments demonstrate Indonesia's intention to establish a more comprehensive carbon market ecosystem and strengthen the role of carbon markets in mobilizing climate finance. Yet the existence of a regulatory framework does not automatically create a functioning market.
For project developers and investors, regulatory uncertainty can translate directly into project delays, additional costs, and difficulties securing long-term investment commitments.
Clear registration and authorization procedures, transparent carbon accounting, defined ownership of environmental attributes, and internationally credible verification standards are therefore essential.
Mt. Stonegate sees regulatory certainty and market integrity not as secondary considerations, but as fundamental requirements for developing a credible and investable carbon market.
Indonesia's carbon market potential is significant, but its success will ultimately depend on whether regulatory progress translates into predictable procedures, genuine market participation, and measurable emission reductions.
Moving Forward: Turning Sustainability Momentum into Action
ISF 2026 reinforced an important message: Indonesia's sustainability transition must now be evaluated not only by what is announced, but by what can actually be delivered. Closing the implementation gap requires stronger alignment between regulatory direction, market accessibility, financing, and business realities.
At Mt. Stonegate Green Asset Management, we support businesses navigating these challenges through our expertise in renewable energy solutions, carbon asset management, and strategic sustainability advisory, helping translate sustainability commitments into practical decarbonization strategies.
As Indonesia's sustainability policies and market mechanisms continue to evolve, we welcome opportunities to exchange perspectives, discuss emerging challenges, and explore potential collaborations with businesses, industry stakeholders, and organizations working to advance the country's energy transition.
