Urgent collaboration between the stakeholders is required to accelerate affirmative action to minimize the threatening socio-economic and environmental impacts of building and infrastructure development.  Effective solutions call for the commitment and engagement of policymakers, urban planners, property developers, architects and civil engineers, construction companies, consultancies and advisors, product and materials suppliers, lenders, investors, academic and research institutions, and civil society.

National governments must establish a base standard for the sustainability of new buildings and incentives to encourage the protection of the environment and social aspects of sustainability.  They must increase their commitments in nationally determined contributions (NDCs) and support the harmonization of regulations and building codes within or across countries to enable a standardized building construction approach and sustainability reporting.

Community councils can encourage change by offering advisory services, technical assistance, in-house advice, and education and by using rating systems for sustainability features and urban design initiatives.  They can further the transition to sustainable construction in their jurisdiction by offering flexibility within local planning provisions, fast-track permitting, and regulation through bylaws and district plans.

Companies are engaged to ensure the delivery of buildings and infrastructure that complies with the principles of sustainable development in the interest of their clients, their funding sources and investors.  Sustainable design, construction, procurement, operation, maintenance, and deconstruction of the built environment calls for the collaboration of all participants along the development project value chain and the whole life cycle of the developed project.

Operators and users of buildings and infrastructure partner for their planning, construction, renovation, operation and use.  Operators can mobilize ambitious levels of national and international resources for effective local operational solutions.

Civil society organizations (CSOs) facilitate the engagement of citizens in the collaboration process.  Strengthening partnerships with civil society enables the collaboration on the development of solutions that meet the needs of the community at large.
