On the occasion of World Environment Day, Mindspace Business Parks REIT (BSE: 543217 | NSE: MINDSPACE) (‘Mindspace REIT’), owner of quality Grade A office portfolio across key office markets in India, unveiled ‘Mindspace Leaves a Mark’ – a sustainability-led participative campaign at its Mindspace Airoli Campus, aimed at creating awareness around Navi Mumbai’s mangrove ecosystem and the growing impact of plastic waste on local wetland ecosystems. Undertaken in partnership with Navi Mumbai Municipal Corporation (NMMC) and NGO Project Mumbai as part of the ongoing Navi Mumbai Plastic & E-Waste Recyclothon, the initiative brought together tenants and employees through an immersive live installation, transforming everyday movement into a collective environmental statement.

Ahead of World Environment Day, Mindspace REIT laid out a 32x48 feet canvas outside a cafeteria and invited people to walk across it, for a purpose far beyond a one-day activation or a community artwork. The initiative was designed to build a deeper connection between people and the mangrove ecosystems that protect Navi Mumbai's coastline, biodiversity, and future. The initiative sought to sensitize participants to the growing threat of plastic pollution, highlighting how plastic waste trapped within mangrove roots gradually breaks down into microplastics, impacting the health of these vital ecosystems and contributing to their degradation over time. 

To bring this cause to life, over 2,400 participants transformed a blank canvas into a vibrant mangrove ecosystem through their footprints. Green footprints formed the mangrove canopy, while blue footprints created the surrounding waterways, turning individual actions into a powerful symbol of collective environmental responsibility. 

Clients, colleagues, and community members came together in support of the cause, motivating and inspiring one another through their participation. Among them was a participant who completed the walk on a prosthetic leg, whose determination became a powerful reminder that every step counts. Together, their collective effort demonstrated how small individual actions can create a lasting impact when united by a shared purpose.  Every participant was awarded with a certificate for not only acknowledging their contribution to the initiative but also serving as a lasting reminder of their commitment towards protecting the environment.

The campaign was built around a commitment - for every person who imprints their footsteps on the canvas, Mindspace REIT pledged to contribute one piece of plastic waste that would otherwise risk making its way into the mangrove roots a few kilometres from the campus.

By the end of the day, the campaign had collected close to 40 kgs of plastic, including 2,400+ discarded bottles and containers. Based on peer-reviewed field data (van Bijsterveldt et al., 2021, Science of the Total Environment; UNEP 2021), this volume of diverted plastic is estimated to reduce plastic stress on approximately 280 mangrove trees in the Thane Creek ecosystem. Plastic collected has been handed over to Project Mumbai as part of the ongoing Navi Mumbai Plastic & E-Waste Recyclothon, under Navi Mumbai Municipal Corporation’s Swachh Bharat Abhiyan and is being upcycled into benches for children at municipal schools across Navi Mumbai. Upcycled sponges and eco-solvent materials were used throughout the installation itself, ensuring the campaign’s environmental commitments extended to its own execution.

Dr. Kailas Shinde, Commissioner, Navi Mumbai Municipal Corporation said, “The Navi Mumbai Plastic and E-Waste Recyclothon is built on the belief that lasting environmental change requires every stakeholder - public, people, and private - at the table, and the partnership between NMMC, Project Mumbai, and Mindspace REIT is exactly that model in action. When civic bodies, NGOs, and corporate neighbours work together through a structured, city-wide programme, the impact multiplies well beyond a single event. Mindspace Leaves a Mark is a strong example of what this collaboration can achieve, and of what happens when a corporate takes genuine ownership of the ecosystem right beside it.”

"We've always believed that a business district and its natural surroundings should thrive together, not despite each other. Mindspace Leaves a Mark was built on that belief. What surprised us was how little convincing people needed, as the community just showed up, and walked for a shared purpose." Ramesh Nair, CEO & MD, Mindspace Business Parks REIT

“Project Mumbai’s work across Navi Mumbai’s schools, housing societies, and now corporate campuses is all part of the same mission - making plastic responsibility feel personal and actionable for every citizen. Mindspace Leaves a Mark brought that mission into a new arena, while also drawing attention to the urgent need to protect the mangrove ecosystems that safeguard our coastline, biodiversity, and local environment. More than 2,400 people walked for the cause in a single day, learning how plastic waste and microplastics threaten these fragile ecosystems and how simple actions can help prevent that damage. The plastic they helped collect will now become benches in municipal school classrooms. That chain, from a footstep to a cleaner mangrove ecosystem to a child’s classroom - is exactly what the Recyclothon partnership was designed to create." Shishir Joshi, Chief Executive & Founder-Trustee, Project Mumbai

“This impactful initiative effectively sensitized business professionals about the vital role mangroves play in protecting Navi Mumbai and preserving our local ecosystems. As regular office commuters like myself were actively encouraged to walk across the blank canvas, the footprints gradually transformed it into a vivid and striking representation of mangrove trees and clean waters. The experience prompted people to stop, take notice, and converse with a renewed sense on the importance of mangrove restoration.” Denver Magdol Nogueiro, Consultant – Climate Change and Sustainability Services (CCaSS), EY

In the weeks leading up to World Environment Day, the campus was activated with footprint-themed installations, standees, and digital communication building awareness around plastic disposal and mangrove conservation. Earlier this year, a part of the larger Plastic and E-Waste Recyclothon, the campus hosted a basketball-themed plastic collection drive and collected 150+ kgs of plastic along with a guided flamingo and mangrove trail walkthrough to create greater awareness around Navi Mumbai’s wetland ecosystem and biodiversity. The initiative will also see mangrove clean-up drives, launch of a community garden beautified entirely from upcycled plastic waste and more. Broader outreach, throughout schools, colleges, and residential societies across Navi Mumbai, has been running in parallel since September 2025.
