Pioneer Cities Reducing Carbon Emissions

The World Economic Forum’s Centre for Urban Transformation released a report today showcasing the best practices of pioneer cities that are effectively reducing carbon emissions from urban development projects.

As urban populations continue to grow, the pace of urban construction is expected to increase. It is projected that the global floor area will double by 2060, which is equivalent to constructing a city the size of New York every month for the next 40 years. The report titled “Reducing Embodied Carbon in Cities: Nine Solutions for Greener Buildings and Communities” outlines nine innovative solutions for various stages of construction and demolition.

Jeff Merritt, the Head of Urban Transformation at the World Economic Forum, emphasized the need for a more comprehensive approach to address carbon emissions throughout the life cycle of buildings. He highlighted the importance of rethinking traditional construction methods and materials, as well as repurposing existing structures to reduce embodied carbon.

The report features case studies that serve as models for cities striving to achieve the Sustainable Development Goals. For example, the One Westside Office Campus in Los Angeles, which was transformed from a struggling mall into a cutting-edge UCLA science campus, diverted over 75% of construction and demolition waste from landfills, resulting in a 33% reduction in embodied carbon compared to a new construction project.

Additionally, a program implemented by San Diego’s local utility company is assisting fleet owners and operators in transitioning to electric vehicles (EVs) to eliminate emissions. The initiative aims to convert at least 3,000 medium- and heavy-duty vehicles, many of which are utilized in the construction industry.

Vancouver has implemented a policy that sets a limit on the amount of embodied carbon allowed in new construction projects. Additionally, they have created a benchmarking tool to accurately measure and track emissions. This proactive approach demonstrates Vancouver’s commitment to reducing carbon emissions and promoting sustainable development. In a similar vein, Seattle has established an expedited permitting process for projects that meet the standards for embodied carbon.

This initiative not only benefits environmentally friendly construction companies but also helps to expedite the construction process while aligning with the city’s environmental goals. New York City has taken a different approach by implementing a Clean Construction Executive Order. This order mandates that all capital project agencies must work towards lowering embodied carbon in municipal construction projects.

By doing so, New York City is actively working to reduce its carbon footprint and promote sustainable practices in the construction industry. According to Jennifer Holmes, Accenture’s lead for cities, transportation, and infrastructure, cities play a crucial role in reducing carbon emissions within the built environment. She emphasizes the importance of cities setting clear targets, providing incentives, and collaborating with the private and non-profit sectors to achieve emission reduction goals.

These cities, along with others, are highlighted in a report developed in collaboration with Accenture following a City Sprint event hosted by the City of Los Angeles. The City Sprint included a three-day workshop with over 50 stakeholders from various disciplines who are committed to transforming the construction industry for the 21st century.

This event builds upon Los Angeles’ commitment to the C40 Cities Clean Construction Accelerator, which aims to reduce embodied emissions by at least 50% for all new buildings, major retrofits, and infrastructure by 2030. Cécile Faraud, Head of Clean Construction at C40 Cities, emphasizes the role of cities in driving demand for sustainable development. She highlights the progress made through the C40 Clean Construction program, with 10 leading cities participating in 2019 and now over 45 cities across all continents working towards decarbonizing the built environment and promoting climate resilience and equity.
