From COP28 to green cities: A call to action

Sustainable urban design, policy advocacy, and citizen engagement are increasingly important to transform global climate goals into local realities after the UN Climate Change Conference.

The COP28 UN Climate Change Conference in Dubai, held from 30 November to 13 December 2023, marked a significant milestone in global efforts to address climate change. With over 85,000 participants, including more than 150 Heads of State and Government, the conference concluded with a groundbreaking 'global stocktake' under the Paris Agreement. The assessment revealed a need for accelerated action in various areas, including reducing greenhouse gas emissions and transitioning to renewable energy sources. These principles are closely connected to urban design, as cities play a crucial role in achieving climate goals. Sustainable urban design, characterized by energy-efficient buildings, green spaces, and efficient public transportation, aligns with COP28's call to transition away from fossil fuels. Cities can contribute by implementing policies that promote renewable energy use, enhancing public transport infrastructure, and creating green, resilient urban spaces. Integrating climate-conscious design into urban planning supports the global commitment to combat climate change and fosters environmentally friendly, sustainable communities. 

The principles advocated by the Congress for the New Urbanism's Charter, which champions walkable urban design, resonate strongly with the objectives set forth by COP28. Emphasizing interconnected streets through grid patterns and complete streets, the Charter encourages a pedestrian-friendly infrastructure that discourages reliance on individual car trips. This not only aligns with COP28's call to reduce greenhouse gas emissions but also promotes healthier lifestyles by prioritizing walking and cycling. The Charter's endorsement of mixed-use development further complements these goals, fostering communities where residents can live, work, and access services within their neighborhoods, minimizing the need for environmentally taxing long-distance commuting. Additionally, the focus on accessible public transportation, such as transit-oriented development and convenient transfers, corresponds directly to COP28's emphasis on aggressive plans to reduce CO2 emissions. By implementing these principles, urban areas can play a pivotal role in mitigating climate change, reducing carbon footprints, and creating healthier, more sustainable communities aligned with the global objectives outlined in COP28. 

Green spaces and public amenities are crucial in bolstering climate resilience and enhancing environmental well-being, aligning seamlessly with the priorities outlined in COP28. As emphasized by COP28's commitment to protecting ecosystems and adapting to climate change, the integration of green spaces within urban planning serves as a frontline defense against environmental challenges. The Congress for the New Urbanism's Charter aligns with this vision through principles such as open space networks, green infrastructure, and walkable streets. Open space networks not only provide recreational areas but also contribute to biodiversity and carbon sequestration, acting as natural carbon sinks. Green infrastructure, encompassing features like permeable surfaces and sustainable stormwater management, mitigates the impacts of climate change by reducing urban heat islands and minimizing flooding risks. Walkable streets, an integral part of the CNU Charter, enhance public spaces by promoting active transportation and reducing the carbon footprint associated with vehicular travel. By incorporating these principles, urban areas can fortify their resilience to climate change, safeguard ecosystems, and create environmentally sustainable communities, aligning with the overarching goals articulated in COP28. 

To advance the goals outlined in COP28 and align with the Congress for the New Urbanism's Charter, it is imperative to enact specific policies at various levels of government – from the municipal to the national level. At the municipal level, local governments can implement policies promoting renewable energy use in buildings. Mandating or incentivizing the installation of solar panels and other renewable energy sources on both residential and commercial structures can significantly reduce reliance on fossil fuels. This policy would directly align with COP28's emphasis on transitioning to renewable energy sources, as it reduces greenhouse gas emissions. Moreover, such initiatives resonate with the principles of sustainable urban design by fostering energy-efficient buildings. Feasibility-wise, many municipalities have successfully implemented solar energy incentives and requirements, showcasing the practicality of such policies. While initial costs may be a consideration, the long-term benefits, both in terms of environmental impact and energy cost savings, make this policy a feasible and impactful avenue for reducing CO2 emissions. 

Moving to the regional level, implementing robust public transportation policies becomes crucial. Investing in the expansion and improvement of public transit infrastructure, coupled with incentives for transit-oriented development, can significantly reduce reliance on individual car trips. This directly supports the principles of the Congress for the New Urbanism's Charter, promoting walkable urban design and discouraging environmentally taxing long-distance commuting. The reduction in vehicular travel contributes to declining carbon emissions and aligns with COP28's call for aggressive plans to address climate change. Feasibility considerations for this policy involve collaboration between regional authorities, transportation agencies, and local governments. Successful examples, such as well-established public transportation systems in various cities, demonstrate the feasibility of this approach. The challenge lies in garnering political and financial support for these initiatives. 

At the national level, policies can be crafted to incentivize green building practices and sustainable urban planning. Providing tax breaks or grants for developments adhering to eco-friendly standards, as outlined in the CNU Charter, can encourage widespread adoption of sustainable practices. This not only aligns with COP28's objectives but also promotes the creation of environmentally sustainable communities. The feasibility of national-level policies lies in the government's commitment to climate action. Governments can play a pivotal role in setting standards, providing financial incentives, and fostering a regulatory environment that supports sustainable urban development. The growing global awareness of climate issues enhances the feasibility of such policies as they gain broader public and political support.  

In addition to government-led initiatives, the feasibility of these policies can be further enhanced through active participation and engagement of ordinary citizens. Citizens play a crucial role in shaping the success of climate-friendly policies at all levels of government. At the municipal level, individuals can advocate for and participate in community initiatives promoting renewable energy. Joining or supporting local organizations focused on sustainable practices can amplify collective voices, encouraging local governments to implement policies favoring solar panel installations and other renewable energy sources. Moreover, citizens can take the initiative to adopt solar panels on their properties, contributing to a grassroots movement that showcases the practicality and benefits of renewable energy. Citizens should be trying to reach out to their local city council member or the governing body of their municipality to make sure their voice is heard. 

On the regional level, citizens can actively support and utilize public transportation. Choosing public transit options, carpooling, and advocating for improved public transit infrastructure are ways individuals can contribute. Engaging with local representatives, participating in community forums, and expressing support for transit-oriented development can help garner public backing, making it more likely for regional authorities to invest in sustainable transportation solutions. 

At the national level, citizens can influence policy through civic engagement. This includes voting for political leaders who prioritize climate action, participating in environmental advocacy groups, and staying informed about policies that promote sustainable urban planning. By advocating for eco-friendly practices, citizens can create a groundswell of public support that encourages national policymakers to prioritize and implement initiatives supporting green building practices. Individual actions, such as adopting energy-efficient practices at home, reducing personal carbon footprints, and supporting local businesses engaged in sustainable practices, collectively contribute to the success of broader policies. The optimistic perspective lies in the power of individuals to drive change through their choices, behaviors, and collective advocacy. By fostering a sense of shared responsibility and optimism, citizens can become active contributors to the feasibility and success of policies aimed at reducing CO2 emissions and promoting sustainable urban development. This collaborative effort between governments and citizens ensures a more optimistic and achievable path towards a greener, more sustainable future. 

In conclusion, the COP28 UN Climate Change Conference underscored the urgency for global action, with sustainable urban design emerging as a key player in addressing climate change. To turn these principles into reality, we must advocate for and implement specific policies at various levels of government. Municipalities can lead by promoting renewable energy use, regions can invest in robust public transportation, and nations can incentivize green building practices. Yet, the success of these policies relies on the active participation of citizens. By engaging in local initiatives, supporting public transportation, and influencing national policies through civic engagement, individuals can collectively contribute to a greener, more sustainable future. Let's unite in our efforts and transform principles into impactful actions for a healthier planet.
