South Africa’s carbon project developers have welcomed renewed policy certainty following the National Treasury’s confirmation of the carbon tax framework through to 2030. Industry representatives say the clarity allows stalled investment pipelines to resume, while cautioning that uncertainty beyond 2030 could constrain future supply.
The Project Developer Forum (PD Forum), which represents more than 60 carbon project developers globally, said the market has returned to “business as usual” after concerns earlier this year over potential changes to the policy timeline. The reaffirmation of Phase 2, set to run from January 2026 to the end of 2030, provides a defined window for project planning and capital deployment.
Developers had previously raised concerns that a shorter adjustment period could disrupt project timelines and delay investment decisions. The four-year Phase 2 horizon is now seen as sufficient to restart pipelines that had been placed on hold, enabling projects to move back into active delivery.
Policy stability is viewed as central not only to emissions reduction efforts, but also to the broader role carbon markets play in South Africa’s economy. A predictable regulatory framework supports investment into projects linked to job creation, community income and land restoration, particularly in rural areas where access to traditional finance remains limited.
South Africa’s carbon project pipeline spans a range of sectors including renewable energy, reforestation, grassland restoration, soil carbon, cookstoves, and waste and fuel-switching initiatives. Recent market developments, such as the launch of JSE Ventures in partnership with Xpansiv and the first local carbon credit trades in 2025, have added new routes to market and increased the importance of policy consistency.
Commenting on the developments Olivia Tuchten, Director at Promethium Carbon said:
“The latest developments around South Africa’s carbon tax provide welcome reassurance and give developers and investors the confidence to plan, deploy capital and deliver projects without the risk of sudden policy changes disrupting established pipelines. The concern earlier this year around a potentially shorter adjustment window was real, and the reaffirmation of the existing framework allows the market to return to business as usual.”
Industry participants point to the role carbon markets already play in directing capital into areas that are typically underserved. These include projects that support emissions reductions alongside socio-economic outcomes such as rural development and improved energy access.
Storm Patel, Commercial Director at TASC and PD Forum member, added:
“Carbon markets are already doing real work in South Africa’s economy, directing capital into land restoration, rural income streams and emissions reductions in areas that struggle to attract traditional finance. With policy certainty in place, we can position carbon markets not as a niche compliance tool, but as part of South Africa’s broader development and transition infrastructure.”
While the confirmation of Phase 2 has addressed near-term concerns, developers say attention is now shifting to the absence of detail around Phase 3, which is due to begin in January 2031. For many projects, particularly nature-based initiatives, development timelines extend well beyond the current policy horizon.
These longer lead times mean that a significant share of future carbon credit supply is expected to come to market after 2030. Without visibility on the regulatory framework that will apply at that point, developers face uncertainty when making investment decisions today.
“The lion’s share of credits from projects being considered today will only become available between 2031 and 2035,” noted Patel. “Without some indication of what Phase 3 looks like, developers face a difficult question: do we commit capital now only to find the framework isn’t there when our credits come to market? That uncertainty is just as unsettling as the Phase 2 speculation was.”
The issue reflects a wider challenge in carbon markets, where long-term supply depends on clear and credible demand signals. Developers require confidence that compliance markets will remain in place and liquid over the lifespan of their projects.
Nick Marshall, Chair of the Project Developer Forum, said the challenge is not unique to South Africa:
“This speaks to a broader market reality. Developers and host countries want to bring supply to international markets that will demonstrably exist and have liquidity. Long-term compliance demand signals, for example from CORSIA, are essential, and without them, the supply needed to meet stated climate commitments simply won’t materialise. For South Africa, Phase 2 certainty is a welcome step, but the conversation on Phase 3 needs to start now.”
South Africa’s carbon tax forms part of its broader climate policy framework, aimed at reducing greenhouse gas emissions while supporting a just transition. Carbon markets are expected to play a supporting role by enabling cost-effective mitigation and channeling finance into priority sectors.
Developers maintain that the progress made with Phase 2 provides a foundation for growth, but stress that timely engagement on Phase 3 will be critical. Without early signals on post-2030 policy direction, there is a risk that investment momentum could slow, affecting the availability of future carbon credit supply.
As the domestic market continues to develop, stakeholders are calling for continued alignment between policy timelines and project development cycles. This, they argue, will be necessary to ensure that carbon markets can contribute fully to South Africa’s long-term climate commitments.
