Imagine that it’s the year 2030. Homes, schools, and offices are built with materials that are lighter on the planet, affordable, and trusted by builders and families. Banks and investors view green projects as attractive for funding. Getting green certification takes weeks, not months. And we no longer have to choose between affordability and sustainability – because these attributes have converged in the solutions available on the market.
While this may seem like a utopian scenario, it doesn’t have to be. The solutions already exist. What’s missing is scale. And for that, we need to change the way we think; to shift from running pilots to building market platforms; from measuring output to creating conditions where adoption becomes natural and seamless.
When it comes to gauging the current penetration of green building materials, key stakeholders have to consider a few core questions. Are people using or buying more of them? Are startups finding it easier to reach the market? Is private capital flowing in? In other words, focusing less on the number of pilots completed and more on whether the market itself is being rewired to make green a default choice.
Take the case of a promising small and growing business from Anand, Gujarat, India. Their product – interlocking blocks that utilized waste – had secured a Life Cycle Assessment (LCA) certificate, carried price points on par with those of traditional materials, and had fared well in early pilots to test real world performance. None of this was enough to sway the market, however. Finding customers willing to switch from conventional materials was still a major challenge.
A similar theme came up during one of our city roundtables in Mumbai, where a young real estate developer, very keen on experimenting with new materials and technology, said: “We want to use these materials, but the risks aren’t clear. Who takes responsibility if something goes wrong?”
Together, these voices – one from the supply and the other from the demand side – point to the same set of systemic bottlenecks. The challenge is not a shortage of green building materials, but a lack of market structures to reduce perceived risk, clarify accountability, and enable confidence at scale.
This becomes even more critical when viewed through the lens of climate risk and affordability. Housing today sits on the frontlines of climate impacts—with heatwaves, flooding, and extreme weather testing the limits of building performance and influencing how much households spend on energy, repairs, and maintenance. These pressures are felt most acutely in the low-income housing segments, where families have limited capacity to absorb higher cooling costs, repeated damage from floods, or premature material failure. In this context, material choices are not just technical or aesthetic decisions. They directly influence the resilience, long-term affordability and durability of their homes.
This is where market platforms can make a difference. Pilots help prove that a technology works; platforms make adoption repeatable. They create shared standards, performance benchmarks, procurement templates, and financing pathways that lower risk for all actors in the system. For impact investors in particular, such platforms are essential—they translate climate and affordability goals into investable, infrastructure-grade opportunities with clearer risk-return profiles.
Building these platforms requires coalition. No single organisation can rewire housing markets alone. For example, Habitat for Humanity’s Terwilliger Center for Innovation in Shelter has been partnering with ecosystem actors such as Saint-Gobain and Villgro Innovations Foundation in a bid to bring together technical expertise, market access, and enterprise support for catalyzing innovation in the built environment. Such collaborations can collectively move green building materials out of niche pilots and into mainstream housing supply chains.
The sector often talks about green homes. But the real task at hand is building the systems that make homes affordable, resilient, and ‘green’ at scale. Housing markets involve a complex web of actors—governments, banks, developers, contractors, material suppliers, and households—each shaping what ultimately gets built. Strengthening these systems is essential, and green building materials represent a critical entry point for aligning climate resilience with affordability.
The Accelerating Innovations in Green Building Materials in India report, jointly developed by Habitat for Humanity and Villgro Innovations Foundation, presents actionable strategies for promoting innovation and driving adoption in this area. It is an invitation to investors, innovators, and ecosystem partners to move decisively from pilots to platforms—and to help ensure that sustainable housing becomes the default choice rather than the exception.
