The carbon cost of real estate

India’s real estate sector stands on the threshold of a vital transformation.

Traditionally shaped by policy reforms, consumer sentiment, and macroeconomic trends, it now faces a new market force: the cost of carbon. With India’s Carbon Credit Trading Scheme (CCTS) launching in pilot form and commercial real estate entering PAT Cycle VI under the Bureau of Energy Efficiency (BEE), carbon management has shifted from voluntary green building efforts to mandatory financial discipline.

This is more than an environmental compliance issue — it is an economic recalibration. According to the World Bank, nearly 24% of global emissions are now covered by carbon pricing instruments. Indian buildings, which account for approximately 25% of national emissions today, are poised to become regulated emitters with financial liabilities attached. Developers, investors, and occupiers must now answer a new question: not just “what is the ROI?” but “what is the carbon cost?” Carbon pricing is not a policy experiment — it’s a new operating reality.

The CCTS, enabled by the Energy Conservation (Amendment) Act 2022, will soon introduce emissions accountability for high-consumption sectors, including real estate. The scheme operates on a rate-based Emissions Trading System (ETS), meaning that entities will be assigned intensity benchmarks — like kilograms of CO₂ per square metre — and must meet or beat them or purchase credits to bridge the gap.

Unlike the earlier PAT Scheme, which focused on industrial energy efficiency, CCTS will monetise carbon, creating market-driven consequences for poor energy performance. The Bureau of Energy Efficiency has already notified energy-use intensity norms for large buildings, and the upcoming National Carbon Registry will link energy audit outcomes to carbon credit eligibility.

Pricing trajectory

The pricing trajectory is already being tested. Internal calculations at BEE suggest that carbon credits may trade in the ₹800–₹2,000/tonne range during the pilot phase. For a five-lakh sq.ft. commercial asset emitting 3,000 tonnes annually, this could mean a ₹24 lakh–₹60 lakh recurring liability if corrective measures aren’t taken.

If the asset overperforms, it could generate surplus credits of equivalent financial value. This dual-edge market mechanism makes carbon performance an active profit-and-loss consideration for developers and asset owners. India’s real estate is entering the regulatory lens traditionally reserved for industries like cement, steel, or thermal power. The reason is simple: real estate is responsible for 38% of global energy-related emissions, and in India, commercial buildings alone consume over 180-220 kWh/sq.m./year. When scaled nationally, this amount is more than the total power usage of Bangladesh or Sri Lanka.

As CCTS evolves, so will the scrutiny around operational performance. Asset valuations will shift accordingly. A JLL India study from 2024 indicated that Grade-A office assets with IGBC or LEED Gold certifications command 8%–11% higher rental yields than their non-compliant peers.

Additionally, buildings with smart meters, rooftop solar, or BMS systems enjoy average energy cost savings of 25%–30%, improving long-term NOI.

Institutional capital is already adapting. Blackstone, Canada Pension Plan Investment Board (CPPIB), and GIC have begun stress-testing Indian real estate assets for ESG compliance. Green premiums are no longer abstract—they show up in deal valuations, especially in REITs. Embassy REIT, for instance, cited its portfolio’s 87% green-certified area as a strategic differentiator in its FY24 investor presentation.

Conscious occupiers

Carbon pricing will not only shape asset ownership economics — it will reshape tenant behaviour. Occupiers, particularly global tech, finance, and consulting firms, are setting internal net-zero targets that require emissions tracking across leased spaces. In 2023, over 45% of Fortune 500 companies operating in India required sustainability disclosures from their landlords as part of lease negotiations.

For example, in Bengaluru, a major US-headquartered technology company declined to renew its lease in a premium but non-certified commercial complex, opting instead for a nearby IGBC Platinum-rated building with a 17% higher lease rate. The reason? The new facility allowed for tenant-level emissions monitoring and reporting — a key requirement for their ESG reporting.

This tenant shift is now influencing developers’ leasing strategies. Green leases, which include shared responsibility for retrofits and energy savings, are gaining popularity. Landlords who can validate energy consumption in real time and participate in decarbonisation efforts are enjoying higher renewal rates and longer lease tenures. A 2024 survey by Colliers India revealed that 72% of tenants would pay more for spaces aligned with sustainability goals. In the era of carbon pricing, building performance is no longer just an engineering parameter — it’s a leasing currency.

Carbon performance is rapidly becoming a differentiator in capital access. Financial institutions in India and globally are integrating climate risk into their underwriting criteria.

The Reserve Bank of India (RBI), in its latest discussion paper, encouraged banks to link risk weights to energy-efficiency performance. For developers, this means that greener buildings will receive more favourable financing terms—and potentially more patient capital.

Indian commercial real estate has already seen green bonds grow from ₹3,500 crore in 2020 to over ₹11,000 crore in 2024. These bonds are increasingly used to fund green-certified projects with demonstrable carbon reductions. Axis Bank, SBI, and HDFC Ltd. now offer green home loan variants with 10-25 bps rate discounts for IGBC/ GRIHA properties.

Moreover, the CCTS introduces the prospect of performance-linked lending. In the EU, banks offer carbon-linked loans where interest rates drop based on verified emissions cuts. This is likely to arrive in India within the next three years. Insurance is also adapting.

No longer theoretical

Delay will prove expensive as carbon costs are no longer theoretical — they’re operational. The smartest developers are now stress-testing their entire pipeline for carbon risk. From conceptual stage to post-occupancy, every decision—from facade material to HVAC selection — impacts emissions exposure.

At present, retrofitting a 5-lakh sq.ft. commercial building with solar, VFD pumps, and BMS can cost ₹4 crore–₹6 crore. But with energy savings of 25%-35% and potential carbon credits of 1,500–2,000 tonnes/year, the payback period often falls below five years. In contrast, inaction will soon invite penalties and carbon liabilities exceeding ₹50 lakhs/year for large assets.

Some developers are already adapting. RMZ Corp has integrated whole-life carbon analysis into its project planning. Godrej Properties now includes ESG scoring in site selection and capital allocation. These are no longer niche practices — they are rapidly becoming industry standards. The Bureau of Energy Efficiency has proposed mandatory energy-use disclosures in building sanction processes by 2026. Urban local bodies may soon embed carbon offsets in Floor Area Ratio (FAR) approvals, much like London’s boroughs.

In an economy poised to grow and urbanise rapidly, real estate is uniquely positioned to decouple growth from emissions. Those who embrace this transition will access cheaper capital, retain premium tenants, and build portfolios that are future-ready. The carbon clock is ticking — and the smartest in the industry are already ahead of it.
