Without mandates for energy performance, incentives for green design, and penalties for high-emissions practices, the market alone is unlikely to move fast enough.

As cities across East Africa race toward economic modernisation, their skylines are transforming. Towering apartment blocks, shopping malls, tech hubs, and logistics parks sprawl outward and upward, symbols of a region on the move. Yet behind the concrete and glass lies an urgent and complex challenge: how to decarbonize one of the region’s fastest-growing, yet most emissions-intensive sectors – the built environment.
Is it mission impossible? Not quite – but it will require bold collaboration, innovative solutions, and a rethink of “business as usual.”
A carbon-heavy footprint
Buildings are responsible for approximately 37% of global energy-related carbon emissions, according to the International Energy Agency. In East Africa, this figure is likely to grow as urbanization accelerates. Nairobi, Kigali, Dar es Salaam, Kampala – these cities are expected to double in size by 2050. Without intervention, the built environment risks locking in decades of emissions through inefficient materials, outdated construction practices, and energy-hungry infrastructure.
“We cannot afford to replicate the mistakes of the past,” says Esther Mugure, a Nairobi-based sustainable urban planner. “Our cities must leapfrog straight into low-carbon development pathways.”
The Triple Challenge
Decarbonising East Africa’s built environment faces a threefold challenge:
- Materials: Cement and steel — construction staples — are carbon-intensive to produce.
- Energy use: Buildings are often poorly insulated, reliant on inefficient cooling, heating, and lighting.
- Urban sprawl: Rapid, unplanned expansion leads to longer commutes, car dependency, and higher embedded emissions.
The mission to decarbonise must therefore address not just how buildings are constructed, but where, with what materials, and how they operate over their lifetimes.
Bright spots: green shoots of innovation
Despite the hurdles, East Africa is showing remarkable ingenuity. Rwanda, for instance, is pioneering green building codes that encourage resource-efficient design from the outset. Kenya’s Eco-Build Africa initiative promotes alternative, lower-carbon construction materials, such as compressed stabilized earth blocks. Meanwhile, innovative private-sector players are stepping in with solutions — from off-grid solar installations on commercial rooftops to new financing models for green retrofits.
In Nairobi, the Global Trade Centre was awarded EDGE Certification for energy, water, and materials efficiency – signaling that sustainable skyscrapers are not just a Western phenomenon.
“Technology transfer and local adaptation are key,” says Jonathan Mburu, an engineer at a regional infrastructure consultancy. “You can’t simply copy-paste green solutions from Europe; they must be tailored to East African realities – like cost, supply chains, and climate.”
Policy: The Make-or-Break Factor
Experts agree that policy leadership will determine success or failure. Without mandates for energy performance, incentives for green design, and penalties for high-emissions practices, the market alone is unlikely to move fast enough. Promisingly, Rwanda and Kenya are both integrating sustainability into national urban plans. Yet enforcement remains a persistent challenge across the region.
There’s also growing momentum behind public-private partnerships. Developers, banks, insurers, and city governments are beginning to realize that climate-resilient, low-carbon buildings are not just good for the planet — they’re good for long-term business stability.
Financing the transition
Perhaps the biggest question: who will pay?
Green buildings typically cost more upfront — although studies show they deliver significant lifecycle savings in energy and maintenance. Innovative financial tools like green mortgages, sustainability-linked loans, and carbon credits for buildings are emerging as ways to bridge the financing gap.
Regional banks and DFIs (Development Finance Institutions) are beginning to back such projects. But scaling up will require mainstream lenders to view green buildings not as luxury products, but as the new baseline for East Africa’s urban future.
The road ahead: courage and commitment
Decarbonising East Africa’s built environment is not an impossible mission. It’s a necessary one – and one within reach if stakeholders across the public and private sectors step up with urgency and ambition.
“We have a unique opportunity,” says Mugure. “We can build cities that are more liveable, more efficient, and more resilient — but we have to start now.”
The region’s rapidly growing cities could become models of sustainable urban development for the rest of the world — or cautionary tales of missed opportunity.
The choice is being made today, brick by brick.
