When the market is saturated, emissions intensity sets you apart.

Clinker factor, the alternative fuel share and kiln heat consumption get reused by PROPER, national emissions reporting and European importers. Record them once per kiln, properly, and compliance cost falls along with fuel cost.

Risk

National capacity far exceeds demand, and cement is among the first subsectors being prepared for mandatory emissions trading. For exporters, European importers have carried the cost of embedded emissions in clinker and cement since 2026.

about 56% projected national cement plant utilisation in 2026.

According to Kontan, 2026; Fortune Indonesia, 2025

Opportunity

Fly ash, slag and pozzolan that replace part of the clinker cut process emissions and cost together. Biomass and refuse-derived fuel (RDF) bring the coal bill down in the same kiln.

81% → 68.1% national clinker factor since 2010.

According to the Ministry of Industry via industry.co.id, 2026

Priority

Set a per-kiln baseline that separates calcination CO2 from fuel, secure the co-processing permit and reclaim the quarry from the first bench. That data fills PROPER, the annual emissions report and importer declarations at once.

  • EU CBAM

    definitive period since 1 Jan 2026; first declaration due 30 Sep 2027

    Without verified actual data, importers use default values with a 10% mark-up in 2026, rising to 30% from 2028.

    According to the European Commission; CBAM Guide, 2026

  • Cement emission standards (Environment and Forestry Ministry Regulation P.19/2017) and SISPEK (Regulation 13/2021)

    in force

    Kiln CEMS must report in real time to SISPEK, the national online emissions system, and hazardous-waste co-processing adds dioxin-furan and CO limits.

From karst reserve to restored quarry, one chain of data.

The limestone reserve chosen at the start sets the quarry's life, its reclamation duties and how much clinker can be replaced. Pick your phase to see what needs to be ready.

Phase 1: The quarry is chosen once; its karst duties last decades.

Limestone almost always sits in karst landscapes that hold springs, caves and endemic species. With national capacity far above demand, feasibility also has to answer where the cement will be sold.

What needs to be ready

    • 1.1 Karst, forest and spatial status

      Confirm the reserve lies outside protected karst landscapes and the state forest estate before applying for the mining licence area (WIUP) and spatial approval (KKPR).

      According to Energy Ministry Regulation 17/2012

    • 1.2 Karst baseline and community rights

      Survey caves, springs, endemic species and downstream water users, then run free, prior and informed consent (FPIC) where the reserve sits on customary land.

    • 1.3 Market and target intensity

      New plant applications are locked in the online licensing system (OSS) except in Papua and Maluku, so feasibility has to win on intensity and haulage cost.

      a national average of 566.3 kg CO2 per tonne of cement equivalent

      According to Fortune Indonesia, 2024; the Ministry of Industry via industry.co.id, 2026

Phase 2: One kiln drawing, three approvals that rely on it.

The integrated quarry-and-plant AMDAL, the kiln emissions approval and the hazardous-waste utilisation approval all cite the same drawings. The alternative fuel line and heat recovery designed now set energy cost for the life of the kiln.

What needs to be ready

    • 2.1 Integrated AMDAL and kiln CEMS

      One environmental impact assessment covers quarry to packing, with CEMS points for particulates, SO2, NOx and CO fixed in the technical study.

      the Environmental Approval is issued within 93 working days in a normal case

      According to Government Regulation 28/2025 and Regulation P.19/2017

    • 2.2 Co-processing and RDF suppliers

      Design receiving and feeding for a minimum calorific value of 2,500 kcal/kg, then set RDF supplier criteria on permits, odour, chlorine and child labour.

      According to Regulation P.19/2017 Annex V and Environment and Forestry Ministry Regulation 6/2021

    • 2.3 A reclamation plan from the mine design

      Prepare the five-year reclamation plan and its guarantee together with the biodiversity plan built on the karst baseline.

      According to Energy Ministry Regulation 26/2018

Phase 3: Dust and vibration on record from the first blast.

Quarry opening and preheater construction run side by side, and residents feel the dust, vibration and trucks before the first clinker comes out. Staged opening and tidy blast records keep the open area small and every complaint answered.

What needs to be ready

    • 3.1 Staged quarry opening

      Open benches to the annual plan, stockpile topsoil and build settling ponds before haulage starts.

    • 3.2 Vibration, noise and dust

      Monitor every blast at the nearest homes and report the results each semester through SIMPEL, the ministry's environmental reporting system.

      a residential noise limit of 55 dB(A)

      According to Environment Ministry Decrees 48/1996 and 49/1996

    • 3.3 Haulage, workers and grievances

      Set load limits and travel hours for construction trucks, record the local-hire share and answer every resident complaint.

Phase 4: The first kiln lights up and the baseline year begins.

The intensity that PROPER, the GCCA target and European importers compare against is the baseline recorded now, kiln by kiln. Operating certificates, validated kiln CEMS and per-unit energy meters make that figure verifiable.

What needs to be ready

    • 4.1 Operating certificate and kiln CEMS on SISPEK

      Apply for the operating certificate (SLO) after trial runs and send hourly CEMS data, because compliance is counted from 95% of daily data.

      According to Environment and Forestry Ministry Regulations 5/2021, 13/2021 and P.19/2017

    • 4.2 Alternative fuel trials

      Measure dioxins-furans, HCl, HF and heavy metals when the first RDF and hazardous waste are fed, because the results set the substitution rate you may run.

      a dioxin-furan limit of 0.1 ng TEQ/Nm³ during co-processing

      According to Regulation P.19/2017

    • 4.3 GHG inventory per kiln

      Separate calcination CO2 from fuel CO2 under the GCCA method, so one figure serves national reporting and importers. The inventory report is due by March every year.

      According to Presidential Regulation 110/2025 and Environment Ministry Regulation 7/2026

Phase 5: Every tonne of clinker replaced shows in rating and margin.

Clinker factor, alternative fuel share and kcal per kg of clinker are assessed by PROPER and verified for importers. Alternative fuel also protects margins when sales are slow.

12.58% vs 29% alternative fuel share, national average against one producer in 2025.

According to the Ministry of Industry via industry.co.id, 2026; Indocement, 2026

What needs to be ready

    • 5.1 From Green towards Gold

      Build evidence on LCA, energy and water efficiency, waste 3R, quarry biodiversity and SROI for village programmes.

      one cement plant reached Gold with evidence of 5,545 GJ saved

      According to Indocement, 2025

    • 5.2 Clinker factor and supplementary materials

      Replace part of the clinker with fly ash, slag, pozzolan or limestone in PCC and PPC, since coal ash (FABA) and slag are already excluded from hazardous waste.

      According to Government Regulation 22/2021 Annex XIV

    • 5.3 Embedded-emissions data for importers and PSPK

      Prepare verified actual embedded emissions per product, process CO2 included, before importers file their first declaration. For listed companies, PSPK 1 and 2, Indonesia's adoption of IFRS S1 and S2, phase in from 2027.

      According to the European Commission; IAI, 2025

Phase 6: Quarry restored, kiln upgraded, permit updated.

An exhausted quarry must reach full reclamation success before its licence area is returned, and the land can become farmland or a carbon project. At the plant, a kiln upgrade or clay calciner changes feedstock and capacity.

What needs to be ready

    • 6.1 Quarry reclamation success

      Monitor springs and cave species until they recover against the baseline, then apply for the reclamation and mine-closure success assessment.

      According to Government Regulation 96/2021 and Energy Ministry Regulation 26/2018

    • 6.2 The old quarry as a mitigation action

      Register agroforestry or revegetation in the national climate registry (SRN PPI) so it earns residents an income and generates carbon units.

      According to Presidential Regulation 110/2025

    • 6.3 Permit changes before a retrofit

      File the addendum before a kiln upgrade, clay calciner or added waste-heat recovery plant is built, because changing operations without amending the permit draws an administrative fine.

      According to Government Regulation 22/2021 Annex V and Environment Ministry Regulation 6/2026
