With society and the real estate industry significantly behind on achieving the targets set in the Paris Agreement, and worsening affordability in Europe’s housing, ULI Europe’s C Change for Housing program has launched a landmark interactive systems map and companion report to help the real estate industry identify, co-create, and scale the solutions needed to decarbonize existing and future affordable housing.
Building on ULI’s existing C Change program, which is focused on accelerating the decarbonization of the built environment, C Change for Housing specifically addresses reducing emissions from Europe’s existing and future affordable homes. This part of the housing system faces particular challenges: aging, inefficient buildings that lock residents into high energy costs, tight operating margins that make retrofit harder to finance, and market dynamics that continue to favour carbon-intensive new build over renovation. Without targeted intervention, affordable housing risks falling behind in the net-zero transition.
Developed through research and consultation with more than 120 experts from investment, development, housing, finance, policy, and the third sector, the new systems map is designed to demystify an intricate landscape, identifying the deep, systemic barriers to achieving progress in the decarbonization of affordable housing. Barriers can include limited uptake of low-carbon innovation to fragmented planning and inconsistent incentives, which undermine progress toward decarbonization targets, and short-term investment horizons, skills shortages, and unused or underperforming land and assets.
Importantly, the map is intended to identify where action can most effectively drive change, and function as a dynamic, living resource where the industry is welcome to submit feedback and contribute ideas to shape the programme. The accompanying report will provide a narrative overview aligned with the structure of the map.
When identifying the barriers it becomes clear that the decarbonisation of affordable housing cannot be solved in isolation and needs to be addressed from a holistic perspective, considering urban planning, finance, construction and all elements part of the value chain, as the broader perspective also holds many of the solutions.
In response, C Change for Housing has identified twelve high impact intervention areas where targeted action can be taken to transform ‘business as usual’ and accelerate progress towards decarbonisation of affordable housing. They have been grouped under five themes:
Strategic foundations
Collaboration and knowledge sharing
| Finance and business
Delivery and innovation
|
These twelve intervention areas represent a practical blueprint for where the industry can work together to unlock system-wide progress. C Change for Housing will initially focus on further exploring and scoping out three intervention areas selected by the steering committee where ULI is best positioned to convene stakeholders and accelerate change. They include:
• Redefining the business case
• Establishing universal definitions and measurement
• Leveraging low-carbon innovation
These priorities may evolve as the programme advances and new opportunities emerge.
The new interactive systems map and report also showcases dozens of case studies and initiatives from across Europe that are already providing real solutions to many of these issues, though often at a local level, ranging from innovative public finance models linking affordability and carbon performance, and digital platforms that track building reuse and circular construction, to low carbon modular micro apartments and serial retrofit projects with prefabricated facades that cut disruption and emissions. C Change for Housing will explore opportunities addressing how to deploy the principles of these exemplar projects at scale.
This mapping exercise marks the first phase of the programme, which will now shift from insight to mobilising the real estate industry to co-develop, test and scale solutions. This will include a series of planned workshops in the coming twelve months.
Sophie Chick, vice president, ESG programs, ULI Europe, comments, “As millions across Europe face high rents and energy costs, and with aging, inefficient homes driving a significant share of emissions, it’s encouraging to see many examples that are already making progress towards decarbonized affordable housing, though most remain small scale. Systemic change, will only be possible through genuine collaboration to scale what already works, align efforts to avoid duplication, and create a new ‘business as usual’ that delivers affordable, low-carbon homes at scale.”
Emily Hallworth, manager, ESG programs, ULI Europe, adds, “C Change for Housing’s first outputs give the industry a shared evidence base and a clear set of intervention points where collective action can have real impact. This launch marks the beginning of a new phase focused on solutions, working with partners to make affordable, low-carbon housing the norm across Europe. Progress on this is essential not only for meeting climate goals, but for creating more resilient, equitable and thriving communities.”
The development of these resources was supported by global built environment consultancy Arup, consultants Dark Matter Labs, the C Change for Housing steering committee, and the ULI project team. The C Change for Housing programme is supported by funding from Laudes Foundation.
