Net Zero in India: A Practical Guide for Businesses Committed to Renewable Energy
Introduction
Net zero has moved from boardroom aspiration to contractual obligation in a remarkably short time. Global supply chains, international lenders, and institutional investors now routinely demand credible decarbonisation roadmaps from their Indian counterparts. Yet for most manufacturing, infrastructure, and services businesses operating in India, the path from commitment to execution remains poorly charted.
This guide explains what net zero actually means in the Indian regulatory and market context, why renewable energy India is the fastest and most cost-effective route to significant emissions reduction, and how organisations can build a practical, auditable transition plan.
What Does Net Zero Mean -and What It Does Not
Net zero means that the greenhouse gases an organisation emits are balanced by an equivalent amount removed from the atmosphere, such that the net addition to the atmosphere is zero. The most important clarification for Indian businesses is that net zero is not the same as carbon neutral, and it is not achieved simply by purchasing offsets.
The Science Based Targets initiative (SBTi) and the GHG Protocol -the frameworks most commonly required by multinationals and development finance institutions -demand a specific structure:
- Scope 1: Direct emissions from owned or controlled operations (boilers, vehicles, process emissions)
- Scope 2: Indirect emissions from purchased electricity and heat
- Scope 3: All other indirect emissions in the value chain (purchased goods, employee travel, product use and disposal)
For most Indian industrial companies, Scope 2 emissions from grid electricity are the largest and most tractable category. This is where renewable energy plays its central role.
Why Renewable Energy India is the Core of Any Net Zero Strategy
India’s electricity grid has one of the higher emissions intensities among major economies -the Central Electricity Authority’s grid emission factor for 2023-24 was approximately 0.716 kg CO₂ per kWh. Every unit of grid power replaced with renewable energy therefore carries a significant emissions benefit.
More importantly, the cost of replacing grid power with renewable energy in India has turned sharply favourable. Open-access solar and wind power is often available at tariffs 20–40% below prevailing industrial grid rates, meaning that decarbonising Scope 2 emissions simultaneously reduces the energy cost base. This is a combination almost unique to India among large economies.
Renewable Energy Procurement Options in India
1. Captive Power Plants
A company installs and owns a solar or wind asset, either on its premises (rooftop or ground-mount) or at a remote location (group captive). Generation is consumed directly, displacing grid purchases. Capital is committed upfront, but long-term tariff certainty and ownership of RECs (renewable energy certificates) are major advantages.
2. Open Access Power Purchase Agreements (PPAs)
The organisation purchases power from a third-party renewable generator via the state open-access framework. Tariffs are contractually fixed for 15–25 years, providing a long-term cost hedge. Open-access charges (wheeling, transmission, cross-subsidy surcharge) vary by state and must be modelled carefully.
3. Group Captive
Multiple organisations co-invest in a shared renewable asset, each holding a proportionate equity stake. This structure unlocks favourable open-access charges while spreading capital risk. It has become increasingly popular among mid-sized industrial consumers.
4. Green Tariff
Several state DISCOMs now offer green tariff programmes, allowing consumers to pay a premium for power backed by renewable generation. This is the simplest procurement route but typically the least cost-competitive.
Building a Net Zero Roadmap for an Indian Business
A credible net zero roadmap for an Indian organisation typically follows five stages:
- Baseline measurement: Establish a detailed GHG inventory covering Scope 1, 2, and material Scope 3 categories. Use actual data, not estimates, wherever possible.
- Target setting: Adopt an SBTi-aligned target covering near-term (2030) and long-term (2050 or earlier) milestones. This will be scrutinised by global customers and lenders.
- Abatement hierarchy: Prioritise emissions reduction over offsets. Renewable energy procurement, energy efficiency, and fuel switching come before any carbon credit programme.
- Procurement strategy: Design and execute a renewable energy sourcing plan matched to your consumption profile, state of operations, and capital position.
- Monitoring and disclosure: Report annually against your targets using a recognised framework (CDP, BRSR, GRI) and subject your methodology to third-party assurance.
Common Pitfalls in India-Specific Net Zero Planning
Several mistakes consistently derail Indian businesses attempting to execute on sustainability commitments:
- Ignoring state-level variation: Open-access rules, charges, and approval timelines differ dramatically between states. A strategy that works in Karnataka may be unviable in a different state.
- Over-relying on RECs: RECs prove renewable origin but do not reduce actual grid dependence. Physical procurement is increasingly preferred by international customers and standard-setters.
- Underestimating Scope 3: As global reporting requirements tighten, Scope 3 emissions -particularly from purchased materials like steel and cement -will attract increasing scrutiny.
- Treating sustainability and cost as a trade-off: In the current Indian energy market, they are not. A well-structured renewable energy procurement plan almost always reduces long-run energy costs.
How Sundesh Supports Net Zero Transitions
Sundesh combines renewable energy EPC capability with energy procurement advisory to help industrial organisations move from target-setting to measurable emissions reduction. Our approach integrates GHG baseline analysis, procurement structure optimisation, EPC execution, and ongoing performance monitoring -so that sustainability commitments translate into actual reductions that can be disclosed with confidence.
Conclusion
Net zero is achievable for Indian businesses, and renewable energy India is the fastest, most cost-effective route to the most material category of reduction. The organisations that move now -before regulatory and customer pressure intensifies – will have built competitive advantage that is very difficult to replicate in retrospect. The question is not whether to transition, but how quickly and through which mechanism.

FAQs
How long does it take to build and commission a renewable energy project in India?
A rooftop solar project typically takes 60–120 days from site survey to commissioning. A ground-mount open-access project requires 9–18 months, including land arrangement, regulatory approvals, EPC construction, and DISCOM interconnection. Group captive structures involve additional legal and equity structuring time of 3–6 months.
What reporting frameworks are used for net zero disclosure in India?
The most commonly required frameworks are BRSR (Business Responsibility and Sustainability Reporting, mandatory for listed companies), CDP, and GRI. Companies with international lenders or global supply chain relationships often also report under SBTi-aligned targets. Third-party assurance of GHG data is increasingly expected.
Which renewable energy procurement option suits Indian industrial companies best?
The right option depends on your scale, capital position, state of operations, and load profile. On-site captive plants suit large consumers with available land. Open-access PPAs work well for consumers seeking no-capex procurement. Group captive structures offer the best balance of cost, charge treatment, and capital efficiency for mid-sized buyers.
What is the difference between net zero and carbon neutral?
Carbon neutral can be achieved through offsetting emissions without actually reducing them. Net zero requires deep, real-world reductions first, with residual emissions addressed by high-quality removals. International frameworks such as SBTi and the GHG Protocol distinguish the two and increasingly require the more rigorous net zero standard.
How does renewable energy in India help achieve net zero?
India’s electricity grid carries one of the higher carbon intensities globally. Replacing grid power with solar or wind through captive plants, open-access PPAs, or group captive structures directly eliminates Scope 2 emissions — typically the largest category for industrial and commercial organisations — while also reducing energy costs.
What does net zero mean for an Indian business?
Net zero means the greenhouse gases your organisation emits are balanced by equivalent removals, so the net addition to the atmosphere is zero. For most Indian businesses, this requires a major reduction in grid electricity consumption through renewable energy procurement — the largest and most addressable emissions category.
