Circular Transition Partners (CTP)
Sustainability advisory, feasibility design and funding support
Private Investment Holding · Southeast Asia
Backing circular, low-carbon and sustainability ventures across Southeast Asia.
Decarb123 Pte Ltd is a Singapore-based private investment holding company. We support ventures that turn waste into value, build circular flows and deliver measurable environmental outcomes.
Our role is quiet and long-term: governance, strategy and alignment behind the operators, not in front of them.
Investment focus
A holding company for real-world sustainability ventures
Decarb123 focuses on circular economy, waste-to-resource and low-carbon models that can be deployed in the real economy across Southeast Asia.
Our role
Decarb123 Pte Ltd is a private investment holding company incorporated in Singapore in 2024. We do not operate as a consulting firm under the Decarb123 name.
Instead, we hold equity interests, provide governance oversight and help structure capital and partnerships around a focused set of sustainability ventures.
- Incubation and ownership of sustainability-linked ventures.
- Strategic input on business models, capital structure and partnerships.
- Oversight and governance at the holding-company level.
Not an operating arm
Operational consulting, project delivery and day-to-day execution are carried out by portfolio entities and implementation partners, not by Decarb123 itself.
This separation keeps our role focused, transparent and free from delivery conflicts, while allowing portfolio companies to build their own brand and capabilities.
- Portfolio companies lead on client work and implementation.
- Decarb123 remains lean, long-term and selective.
- New opportunities are evaluated conservatively and confidentially.
What we look for
We selectively engage with ventures that meet three simple tests:
- Measurable environmental impact — in circularity, carbon reduction or resource recovery.
- Operators with technical depth and demonstrated ability to execute projects in the field.
- Commercial models with a credible path to sustainable scale in Southeast Asia.

How we work
Quiet, hands-on and long-term
Our approach is to stay close enough to matter, and far enough away to let operators operate.
-
Selective entry. We prefer to work with a small number of ventures where our involvement is clearly additive and aligned with long-term sustainability outcomes.
-
Aligned incentives. We look for structures where founders, operating partners and Decarb123 share a common view of value creation and impact, not just short-term revenue.
-
Structured governance. We focus on boards, reporting lines and decision rights that keep ventures accountable without suffocating innovation.
-
Real-world validation. Preference is given to ventures with tangible projects, paying customers or credible pathways to deployment rather than purely conceptual propositions.
What we are not
Decarb123 is not a fund manager, public vehicle or advisory shop. We do not solicit capital from the public, and we do not market consulting services under the Decarb123 name.
All operational engagements, client-facing work and project delivery are run through portfolio companies and implementation partners. This site is a high-level overview of Decarb123’s role as an investment holding company only.
