Key Takeaways

• City governments should prioritize retrofitting existing buildings to meet emissions reduction goals.
• Decarbonising the construction sector by reducing embodied carbon is crucial for sustainable development.
• Implementing city-wide retrofitting initiatives can significantly impact climate change mitigation efforts.

Urban Retrofitting: A Path to Emission Reduction

Mahesh Ramanujam, the president and CEO of the Global Network for Zero, emphasizes the critical role of city governments in advancing climate action through retrofitting existing buildings. With urban populations increasing and climate change posing significant threats, retrofitting offers a viable solution to reduce carbon emissions substantially.

Many cities face challenges in reaching their emissions reduction targets, primarily due to the large percentage of emissions generated from existing buildings. These structures often require significant energy to operate, contributing to overall consumption. By focusing on retrofitting, cities can enhance energy efficiency and significantly lower carbon footprints without constructing new buildings.

Ramanujam advocates that targeted retrofitting can serve as a gamechanger in achieving a sustainable urban environment. City-wide initiatives could lead not only to improved building performance but also to economic opportunities, job creation, and community development. Collaborating with local businesses and communities in these efforts enhances the overall impact, fostering public engagement and awareness of climate issues.

Another critical aspect highlighted is the need to address embodied carbon in the construction sector. Embodied carbon refers to the greenhouse gases emitted during the production of building materials and their transportation. Reducing these emissions is essential for a holistic approach to decarbonisation. Implementing policies that prioritize low-carbon materials and sustainable construction practices can further amplify the effectiveness of retrofitting projects.

In summary, accelerating retrofitting programs and reducing embodied carbon are vital components of a successful climate strategy for city governments. Ramanujam calls for an urgent shift in focus towards existing structures, encouraging stakeholders to embrace and invest in sustainable urban solutions. By doing so, cities not only work towards mitigating the adverse effects of climate change but also pave the way for a greener, more resilient future.
