How carbon pricing, energy regulations, and tenant demands are turning sustainability into a financial priority for developers and investors
Why Sustainable Buildings Are Becoming a Financial Necessity
India's real estate sector is undergoing a major transformation. Until recently, factors like policy reforms, market trends, and consumer demand were the key drivers of growth. Today, there’s a new and powerful force reshaping the landscape — carbon accountability.
With the launch of India’s Carbon Credit Trading Scheme (CCTS) and the inclusion of commercial real estate under the Perform, Achieve, and Trade (PAT) Cycle VI by the Bureau of Energy Efficiency (BEE), carbon emissions are no longer just an environmental issue — they are a financial liability.
From Voluntary to Mandatory: A Shift in Sustainability
Previously, real estate developers focused on green buildings as a matter of choice or branding. Now, it's becoming a regulatory requirement with financial consequences. Globally, around 24% of emissions are already priced under various carbon trading systems, according to the World Bank.
In India, buildings contribute to 25% of total national emissions. As carbon pricing becomes mandatory, developers, investors, and occupiers must start asking not just “What is the ROI (Return on Investment)?”, but also “What is the carbon cost?”
What Is the Carbon Credit Trading Scheme (CCTS)?
The CCTS, introduced through the Energy Conservation (Amendment) Act 2022, is a market-based mechanism to reduce carbon emissions. Under this scheme:
Buildings are assigned energy intensity benchmarks — such as kilograms of CO₂ emitted per square meter.
If a building emits more than the limit, it must buy carbon credits to offset the extra emissions.
If it emits less, it earns carbon credits it can sell — turning sustainability into a profit opportunity.
This system, unlike the earlier PAT Scheme (which focused mainly on industries), directly monetises carbon emissions in real estate.
The Cost of Carbon: Real Numbers, Real Impact
Carbon is no longer a theoretical metric. It has a real price tag. During the CCTS pilot phase, credits may trade between ₹800 and ₹2,000 per tonne.
For example, if a 5 lakh sq.ft. commercial building emits 3,000 tonnes of CO₂ annually:
The carbon cost could be ₹24 lakh to ₹60 lakh per year, if emissions aren’t reduced.
However, if the building performs better than the benchmark, it could earn surplus credits worth the same amount.
This creates a profit-and-loss impact directly tied to carbon efficiency.
Why Real Estate Is in Focus
Globally, real estate is responsible for 38% of energy-related emissions. In India, commercial buildings consume 180–220 kWh per sq.m per year — more than the total electricity used by some neighbouring countries.
Because of this, commercial real estate is now being regulated just like heavy industries such as steel, cement, and power.
Market Response: Higher Value for Greener Buildings
Asset value is now influenced by sustainability. A 2024 JLL India study found:
Grade-A office buildings with LEED or IGBC Gold certifications earn 8%–11% higher rental yields than uncertified ones.
Buildings with rooftop solar, smart meters, and Building Management Systems (BMS) save 25%–30% in energy costs, increasing Net Operating Income (NOI).
Big investors like Blackstone, CPPIB, and GIC have already started checking ESG (Environmental, Social, Governance) compliance before investing. For example, Embassy REIT highlighted that 87% of its portfolio is green-certified, helping it stand out to investors.
Tenants Are Driving Change Too
It’s not just investors — tenants now demand sustainable spaces.
In 2023, over 45% of Fortune 500 companies in India asked landlords for sustainability disclosures during lease discussions.
A US tech company in Bengaluru recently moved out of a premium but non-certified office to a nearby IGBC Platinum-rated building, even though the new place had a 17% higher rent. Why? The new building allowed them to track and report emissions — a requirement for their global ESG targets.
This trend is encouraging the rise of green leases — rental agreements where landlords and tenants share responsibility for energy savings and emission reductions.
A 2024 Colliers India survey found that 72% of tenants are willing to pay more for buildings aligned with sustainability goals.
Carbon Efficiency = Better Finance Terms
Banks and financial institutions are also rewarding greener buildings:
The Reserve Bank of India (RBI) has encouraged banks to link loan risk ratings to energy efficiency.
Green bonds in Indian real estate grew from ₹3,500 crore in 2020 to over ₹11,000 crore in 2024.
Banks like Axis Bank, SBI, and HDFC offer green home loans with 10–25 basis point (bps) interest rate discounts for certified buildings (like IGBC or GRIHA rated).
Soon, India may also see carbon-linked loans, like in Europe, where interest rates reduce as buildings cut emissions.
Carbon Is Now a Design and Operations Concern
Carbon management now needs to be built into every stage of development — from design to operations. For example:
Retrofitting a 5-lakh sq.ft. building with solar, VFD pumps, and BMS may cost ₹4–₹6 crore.
But with 25%–35% energy savings and 1,500–2,000 tonnes of carbon credit per year, the payback period is often under 5 years.
In contrast, doing nothing could lead to over ₹50 lakh in carbon penalties annually.
Forward-looking developers are already acting:
RMZ Corp now uses whole-life carbon analysis to guide planning.
Godrej Properties uses ESG scoring to decide where to build and where to invest.
These aren't isolated practices anymore — they’re becoming new industry standards.
The Road Ahead: Regulation Is Catching Up
The Bureau of Energy Efficiency (BEE) has proposed that by 2026, all building sanction processes must include energy use disclosures.
In the future, local urban bodies might even tie carbon offset contributions to FAR (Floor Area Ratio) approvals — a model already followed in parts of London.
India’s real estate sector sits at a crossroads. With rapid urbanisation ahead, there's a unique opportunity to decouple growth from emissions.
Carbon costs are no longer distant threats — they are immediate financial realities. Developers who adapt will benefit from:
Cheaper capital
Premium tenants
Higher valuations
Regulatory readiness
Those who delay risk penalties, shrinking margins, and loss of competitiveness.
In this new era, carbon performance is as important as construction quality. The smart players in the industry are already moving — and those who don’t will be left behind.
