Decarbonization Subsidy (IDP 4.0) — Up to 35% for AP Red Category Industries

The Decarbonization Subsidy is a capital incentive built into Andhra Pradesh's Industrial Development Policy 4.0, usually shortened to IDP 4.0. It is delivered by the state's Department of Industries & Commerce and is aimed squarely at Red category industries that want to lower the carbon intensity of their operations.

The scheme exists because cleaner production generally costs more up front. By sharing a slice of the project cost, the state reduces that entry barrier and makes the shift to low-carbon technology more commercially workable. The broader intent is an industrial base in Andhra Pradesh that can hold its own in markets where sustainability now shapes buying decisions, while pulling fresh green investment into the state.

Support is not uniform. It runs in tiers so that businesses of different scales — Sub-Large, Large, Mega and Ultra-Mega — each get backing that reflects the size of the investment they are making. Units qualify whether they are setting up a new project, expanding an existing one, or diversifying into fresh lines, as long as the spending goes into climate-friendly machinery, plant and equipment.

• Capital subsidy for Red category industries in Andhra Pradesh
• 15% / 25% / 35% of project cost depending on industry scale
• Payout capped at 6% of eligible Fixed Capital Investment
• Disbursed in tranches over 5 to 10 years
• Covers new projects, expansion and diversification
• Applications accepted on a rolling basis under IDP 4.0

The subsidy is open to industries classified under the Red category in Andhra Pradesh. A unit can apply whether it is putting up an entirely new project or an existing one going in for expansion or diversification, and the capital spend must be directed at climate-friendly machinery, plant and equipment.

• Industry classification: Red category industries.
• Project type: new unit, expansion, or diversification.
• Industry scale: Sub-Large, Large, Mega and Ultra-Mega industries.
• Nature of investment: capital spending on climate-friendly machinery, plant and equipment.

All four scale categories are covered, so the tier a unit falls into decides the rate of support rather than whether it can apply at all.

Decarbonization Subsidy (IDP 4.0) — Up to 35% for AP Red Category Industries is open to startups at any stage. It is open to startups registered anywhere in India.

Decarbonization Subsidy (IDP 4.0) — Up to 35% for AP Red Category Industries accepts applications on a rolling basis — there is no fixed cut-off date, so eligible startups can apply at any time. Because rolling programmes can pause without notice, confirm the window is still open on the official site before you start.

The subsidy is worked out as a share of project cost, and that share grows with the scale of the industry.

• Sub-Large industries: 15% of project cost.
• Large and Mega industries: 25% of project cost.
• Ultra-Mega industries: 35% of project cost.

Whichever tier applies, the payout is capped at 6% of the eligible Fixed Capital Investment (FCI). That ceiling keeps the incentive anchored to the verified capital base rather than to the headline project figure.

Approved amounts are not released in one go. Disbursement is spread across 5 to 10 years, with the exact period depending on the industry category. The support is a cash capital subsidy, so it is non-dilutive — no equity or ownership stake is taken in the applicant's business.

Decarbonization Subsidy (IDP 4.0) — Up to 35% for AP Red Category Industries is offered by Department of Industries & Commerce, Government of Andhra Pradesh, a government body. As a government-backed subsidy, it is publicly funded and open to eligible startups across India. You can verify current details and timelines on the provider's official website before applying.

Applications are assessed by the Department of Industries, Government of Andhra Pradesh, against the conditions set out in Section 7.4 of the IDP 4.0 policy.

The department first screens each submission for basic eligibility. This check confirms the unit's Red category classification, whether the industry falls under Sub-Large, Large, Mega or Ultra-Mega, and whether the proposed spending genuinely goes into climate-friendly machinery, plant and equipment.

The project proposal is then evaluated on its feasibility, its environmental impact and how well it aligns with the policy's objectives. Alongside this, the eligible Fixed Capital Investment is scrutinised, because the FCI figure determines the maximum subsidy an applicant can receive.

Final approval follows a consolidated assessment covering the application and the project's compliance with all the stated terms of the policy.
