The short answer

How do cement plants earn or owe carbon credits under CCTS?

186 cement units have targets in tonnes of CO2e per tonne of product, to four decimals. Credits = (target minus actual intensity) × output. Beat it and you earn credits to sell. Miss it and you buy credits, or pay twice the average credit price within 90 days.

Last verified 3 October 2026. Sources at the end.

Four decimals, in crores.

The target prints to four decimals. Here are three data choices that move yours. Flip them.

Indian kilns burn 731 kcal per kg of clinker. The world average is 838.
The easy savings are gone.

The next credit comes from clinker, fuel and power. Clinker drives 85 to 90% of cement CO2, and India’s alternative fuel share is about 6% (ACEEE, June 2026).

Why now

Who’s asking, and by when.

186 plants

Targets are law

Cement units named in the October 2025 GEI target rules, each with its own number.

2x

The cost of missing

Environmental compensation is twice the average credit price, payable within 90 days.

Up to 19%

Profit at risk

ICRA says some cement makers’ profits could fall by up to 19% by FY27, at $10 a credit.

UK CBAM

The UK adds cement to its CBAM. The EU’s first declaration is due 30 September 2027.

How this is worked out
  • Calcination: 520 kg CO2 per tonne of clinker, the IPCC 2006 default with dust correction.
  • Kiln fuel: kcal/kg × 4.1868 × 94.6 kg CO2 per GJ for coal, 97.5 for pet coke (IPCC 2006). Alternative fuels counted as zero here.
  • Power: 0.675 t CO2 per MWh, India’s grid average for 2025-26 (CEA v22). RE and WHR counted as zero here.
  • Target: baseline less the sector’s average cut (ICRA: 0.7% for 2025-26, 2.7% for 2026-27). Use your gazette row for the real figure.
  • Credits = (target − intensity) × output. Compensation if unpaid: twice the average credit price (GEI Target Rules 2025).
  • Scenario tool. BEE’s procedure may normalise for product mix. It isn’t your filing.

Sound familiar?

Plant heads and CCTS owners

Tell me by Monday if this plant buys or sells credits this year. And how many.

Sustainability and BRSR teams

The auditor asks where 0.5800 came from. I need to show the bills, not a pivot table.

Institutional sales and exports

The tender wants kg CO2e per tonne by Friday. We only have the company-wide number.

Paraphrased from our conversations with cement teams.

Answer the CFO in rupees.

The question in every board pre-read this year. Same question, two answers.

Board_Preread_Q3_FY27.docxSection 4 · Carbon
Question 4.2 For FY 2026-27, how many carbon credit certificates will each plant buy or sell, at what price, and how sure are we of the number?

Wording modelled on board and CFO questions we hear.

  • Know the bill. Credits per plant, in rupees, every month.
  • Price the levers. Alternative fuel, clinker factor and WHR, compared in credits.
Straight answer: CCTS numbers follow BEE’s procedure, and it sets your filing’s rules. Our calculator is for planning. For an EPD a buyer can rely on, you still need a third-party verified study. We get your data ready for it.
From the field

What cement teams ask us first.

CFOs

“Is this plant a buyer or a seller?”

A plant can beat its own baseline and still be short. The calculator above shows how.

Plant heads

“Which lever pays back first?”

Alternative fuel, clinker factor and WHR power, priced in credits, side by side.

How it works

From the kiln log to the board pack.

Carbon-OS reads your SAP, fuel and power data. One ledger runs CCTS, BRSR and buyer declarations.

  1. Connect

    SAP, fuel and power data, plant by plant.

  2. Rebuild

    Each plant’s baseline and target from the gazette.

  3. Track

    Monthly intensity with a year-end projection.

  4. Act

    Levers in credits, the CCTS filing, BRSR tables, buyer answers.

Method and boundary

CCTS
Per obligated plant, per the GEI Target Rules 2025 and BEE’s procedure. t CO2e per tonne of equivalent product, four decimals.
Calcination
Clinker × 0.52 t CO2 per tonne (IPCC default), or plant CaO and MgO analysis where you have it.
Fuels
Fuel × lab NCV × IPCC 2006 factor. Biomass and wastes tracked by share.
Power
Grid at CEA v22. Captive, WHR, RE and open access split by meter.
BRSR
Company Scope 1 and 2 from the same plant ledger.
Products
A1 to A3 per tonne as a scenario estimate, ready for a verified EPD. It isn’t an EPD.
CBAM
Embedded emissions per installation for EU and UK buyers.
Glossary

Eight terms, in plain words.

GEI target
The CO2e per tonne your plant must hit each compliance year.
Carbon credit certificate
One tonne of CO2e under target, issued by BEE. You can trade it.
Environmental compensation
The charge for a shortfall: twice the average credit price.
Clinker factor
Tonnes of clinker in each tonne of cement.
TSR
Share of kiln heat from biomass and wastes in place of coal or pet coke.
WHR
Power made from kiln and cooler exhaust heat.
Equivalent cement
Output converted to one unit so plants compare fairly.
EPD
A third-party verified report of a product’s footprint, to ISO 14025.
Where are you today?

Three questions. Your first steps.

See where we'd start with you.

Which best describes you?

Do you know each plant’s 2026-27 position?

What do you need first?

Questions cement teams ask.

How many cement plants are under CCTS?

186 units, named in the GEI target rules of 8 October 2025, each with its own baseline and two targets.

What is the baseline year for cement under CCTS?

2023-24. Targets apply to 2025-26 and 2026-27.

How big are the CCTS cuts for cement?

On average 0.7% for 2025-26 and 2.7% for 2026-27, according to ICRA. Each plant’s number differs.

What if a cement plant misses its target?

It buys credits, or pays environmental compensation at twice the average credit price within 90 days.

What if a cement plant beats its target?

It earns carbon credit certificates, one per tonne of CO2e, to sell or bank.

Are grinding units covered by CCTS?

Yes. Their intensities are much lower and come mostly from power.

Why does the fourth decimal matter?

Targets print to four decimals. On 20 lakh tonnes, 0.0001 t per tonne is 200 credits.

What moves cement intensity most?

Clinker. It drives 85 to 90% of cement CO2. Then kiln fuel and power.

Does WHR power help a cement plant’s intensity?

It cuts grid power and the CO2 that comes with it. Check how BEE’s procedure counts it for your plant.

Does EU CBAM apply to cement?

Yes. Reporting began in October 2023, and certificates are due on imports from 1 January 2026. The first annual declaration is due 30 September 2027. Importers under 50 tonnes a year are exempt.

Does UK CBAM cover cement?

Yes, from 1 January 2027.

Is the calculator an official CCTS figure?

No. It’s a scenario estimate on IPCC and CEA factors. Your filing uses your plant data and BEE’s procedure.

Bring one plant’s data. We’ll tell you which side you land.

Twenty minutes. Your kiln, your fuel, your power. You leave with your credit position in rupees.
