Q3 League Table: Indonesia’s Largest Carbon Projects

KarbonLens currently tracks 69 Indonesian projects with 25,668,148 credits issued across the covered universe. This league table orders the largest projects in the KarbonLens project database by credits issued, using the exact issued-credit figures available in the grounding data.

Katingan Peatland Restoration and Conservation Project leads the field with 6,912,990 credits issued, ahead of Rimba Raya Biodiversity Reserve Project at 5,657,624 credits issued. The scale of these leaders is materially different from the rest of the table: both are large avoided-deforestation and peatland-oriented assets, and both have accumulated issued-credit balances that place them firmly at the top of the Indonesian project universe covered here.

The next tier shows that the market is not led by a single project type. Sumatra Merang Peatland Project (SMPP) has 2,638,073 credits issued, while 82 MW Lau Renun Hydro Power Plant, North Sumatra has 2,599,898 credits issued. That pairing puts a peatland project and a hydro project in close proximity on the leaderboard, showing that Indonesia’s issued-credit base is spread across both land-sector and energy-sector activities.

Below those entries, the table remains energy-heavy. 210 MW Musi Hydro Power Plant, Bengkulu has 1,867,252 credits issued, 50 MW Sipansihaporas Hydro Power Plant, North Sumatra has 1,687,679 credits issued, Capacity Upgrade of Gunung Salak Geothermal Power Plant Project, Indonesia has 1,611,746 credits issued, and Wayang Windu Phase 2 Geothermal Power Project has 1,451,189 credits issued. Hydro and geothermal projects therefore form a deep middle of the ranking, even though the very top remains dominated by forest and peatland names.

The lower end of the table is still strategically relevant for market monitoring. MedcoEnergi Associated Gas Recovery and Utilization Project has 492,803 credits issued, while Mangrove restoration and coastal greenbelt protection in the East coast of Aceh and North Sumatra Province, Indonesia has 397,071 credits issued. Together, these entries broaden the leaderboard beyond the familiar peatland, hydro and geothermal categories, signalling a market in which established large-scale supply anchors coexist with more specialised activities that may matter for buyer preferences, co-benefit screening and future issuance pipelines.
