Bengaluru, Karnataka, 5th of November, 2026 : Occupiers’ preference for sustainable workspaces continue to gain prominence across key markets, with green certification becoming a ‘hygiene factor’ rather than a differentiator in India’s office market. Office developments certified under recognized sustainability frameworks such as LEED, IGBC, GRIHA etc. (referred as “Green assets”) are increasingly shaping occupiers’ real estate strategies across India. Designed for greater resource efficiency and lower environmental impact, these buildings also offer enhanced workplace quality.
Leasing in green assets is projected to reach 60-65 million sq ft across the top seven cities in 2026, increasing its share in overall leasing to over 80% from 74% in 2023. This trend highlights the growing integration of ESG priorities into corporate real estate strategies and expansion plans. It also reflects increased corporate awareness of energy efficiency, carbon emissions and employee well-being, reinforcing the role of sustainable built environments in advancing broader climate and sustainability commitments.

“The ability to deliver higher portfolio valuations, improved rentals, and stronger occupancy levels continues to strengthen the case for green assets amongst investors and developers alike. This trend is deepening across cities, with occupiers having leased more than three-fourths of their office space in green assets over the last 3-4 years. Interestingly, technology firms have emerged as the largest occupiers of green assets, driving sustainability-led workplace strategies. Going forward, 80-90% of occupiers across sectors are likely to align their corporate real estate strategies with broader ESG goals through space uptake in green assets,” says Arpit Mehrotra, Managing Director, Office Services, Colliers India.
Around 70% of the Grade A office stock in India is currently green-certified
As occupier preferences increasingly gravitate towards sustainable workplaces, the stock of green assets is set for substantial growth. By 2026 end, nearly 70% of Grade A office inventory across India’s top seven cities is expected to be green-certified. Notably, Bengaluru and Delhi NCR are likely to reaffirm their prominence as key hubs of sustainable office development, together accounting for nearly half of the country’s green assets by 2026.
Interestingly, green assets are expected to account for 75-80% of new supply and reach 45-50 million sq ft during 2026, highlighting the increasing dominance of sustainable developments in the supply pipeline. Over the next two to three years, most of the upcoming supply across the top seven cities is expected to be green-certified, taking the total green stock close to the 800 million sq ft mark, up from 600-650 million sq ft at present.

“Growing adoption of sustainable elements in workspaces across occupier segments is encouraging developers to align new offerings with evolving occupier preferences. At the same time, over 450 million sq ft of existing office stock is more than a decade old and may warrant significant upgrades, creating a sizeable opportunity for retrofitting. Most redeveloped assets are expected to obtain green certifications, complementing the upcoming development pipeline and accelerating green penetration across key markets. Resultantly, green assets could account for nearly three-fourths of the country’s office inventory by 2030,” says Vimal Nadar, National Director and Head of Research, Colliers India.
Beyond sustainability benefits, green buildings enhance operational efficiency, workplace quality, and employee well-being, ultimately supporting higher productivity and business performance. Importantly, as developers and occupiers increasingly align their real estate decisions with ESG-driven strategies, green assets will continue to gain prominence as the preferred workspace choice.
