This position paper is the result of a working group on the topic of sustainable construction and the urban poor, facilitated by the Cities Alliance Secretariat.

The forthcoming decades will witness a surge in urban construction, particularly in the form of incremental upgrading and makeshift homes across the Global South.

Cities Alliance - Can the Urban Poor Afford Sustainable Construction? cover

Given the alarming contribution of the built environment to CO2 emissions, standing at almost 40 per cent, and the imminent depletion of the CO2 budget for this sector, a strategic focus on sustainable construction is indispensable to achieve the ambitious target of limiting global warming to 1.5 degrees Celsius.

Against this background, Cities Alliance has been exploring how the circular economy can benefit residents in cities, especially those living and working in the informal sector.

We focus on the connections between sustainable building, gradually improving informal settlements and innovative building methods.

We have invited members and partners to join a working group to discuss challenges, identify opportunities, and plan how individuals in informal settings can be part of sustainable construction.

This position paper is the first outcome of the working group. The publication seeks to spotlight alternative, circular, and low-carbon construction methods while advocating for their simultaneous attractiveness and affordability. It underscores the importance of supporting sustainable construction through political frameworks and regulations, thereby fostering the creation of more resilient and environmentally friendly buildings and infrastructure in cities.


The paper prioritises inclusivity and equity, emphasizing the responsibility of governments in establishing regulations that foster sustainable construction.
