Guilty as charged: cities and urban populations are among the core drivers of anthropogenic climate change. Cities produce between 71% and 75% of total greenhouse gas (GHG) emissions1. There needs to be a ‘paradigm shift towards low emission and climate-resilient development pathways’. A shift that can happen in developing countries by supporting and investing in high impact climate mitigation as well as resilience and adaptation initiatives.
While the paradigm shift is defined by the ‘degree to which the proposed activity can catalyse impact beyond one-off project or programme investment’, the reality is not so straightforward in the context of the urban sector. Urban areas are complex, multi-stakeholder environments that require holistic, structurally sound, sustainable solutions. They need transformative investments in energy efficient buildings; decarbonising urban energy systems; compact and resilient urban development (including investment in mass transit and non-motorised transit systems and vehicle electrification); grey to green urban infrastructure upgrading; the circular economy; and methane and emissions-free integrated waste management.
Demand pressure on developing new urban infrastructure is high: new homes and infrastructure will have to be built at great speed for the approximately 2.5 billion new city dwellers expected by 2050. About 85% of new housing demand is projected to be in fast emerging economies (such as China) and in the majority of developing countries. Furthermore, of the 70 million new residents expected to move to pre-existing urban areas each year, the vast majority will live in intermediary cities, mostly in Africa and Asia. This adds to climate pressures, both in terms of accelerated emissions and enhanced vulnerabilities.Continue reading
