The GlobalABC is co-lead of the Built Environment Track of the Human Settlements Pathway!
The Human Settlements are one of the Thematic Areas of the Climate Action Pathways, which are a vital part of the Marrakech Partnership for Global Climate Action (MPGCA) tools to enhance climate action and ambition towards fully implementing the Paris Agreement. The Pathways aim to provide a roadmap to help Parties and non-Party stakeholders alike to identify actions needed by 2025, 2030 and 2040 as steps to get to the 2050 vision of a 1.5°C resilient world. In this regard, the climate action pathway for human settlements addresses whole-life carbon mitigation, adaptation and resilience in the built environment, as well as waste and consumption within human settlements.
Restricting climate change to 1.5°C would need “rapid and far-reaching” changes around energy use, industry and buildings design, as well as the wider planning of cities and infrastructure. The buildings and construction sector currently account for almost 40% of global energy and process-related carbon emissions, while around half of buildings that are predicted to exist in 2050 have yet to be built. Continuing in this direction, over 970 cities could be subjected to extreme heat, 500 cities could suffer from lack of water availability, and over 570 cities could be impacted by sea level rise by 2050. If action is not taken today, we risk locking emissions and vulnerability into our buildings and infrastructure that will become increasingly costly to mitigate in the future. Based on this critical observation, the built environment track of the Human Settlements climate action pathway outlines a set of necessary stakeholder (i.e. policy makers, financial institutions, technology providers and innovators, business and service providers and civil society) actions to be taken to accelerate the transition to a net-zero carbon, healthy and resilient built environment.
