How Urban Areas Can Combat Climate Change: Innovative Strategies for a Cooler Future

Cities play a big role in the fight against climate change. They are responsible for about 67–72% of greenhouse gas emissions, which are warming our planet. Meanwhile, cities also face serious risks from climate impacts like floods, wildfires, and droughts. This has wide-ranging effects, from the costs of insuring homes to public health and safety concerns.

With around 90% of Australians living in urban areas, and more than four billion people globally residing in cities, addressing this issue is vital. Our recent study highlights 16 key actions for urban construction and management that can help tackle climate challenges.

Designing Smart Cities

When building cities, we must prioritize climate change. This means reducing and eventually eliminating emissions. Current building policies often fall short in preventing climate risks.

A recent study of three local government areas revealed a lack of action on climate adaptation. Many urban policies don’t include strong carbon reduction goals to meet international standards. As part of the National Housing Accord, over one million new homes are planned by 2029, and they need to address climate concerns.

Identifying Key Actions

In our study, we consulted over 150 stakeholders from fields like urban planning, architecture, and sustainability. They identified priority actions that span the entire life cycle of city development.

One major hurdle is the perceived powerlessness among professionals to push for climate action, as many feel property owners or clients have more influence. It’s crucial to identify climate risks early in planning, supported by tools that ease this process.

Urban planners noted that areas prone to flooding lacked strategies to manage those risks. There’s a call for policies that mandate climate action at the design stage to help professionals advocate for necessary changes.

Improving climate knowledge across workforce disciplines is essential, as is selecting sustainable materials. Also, many see the highest challenges arise during approvals and budgeting; if climate initiatives aren’t legally required, they often get overlooked.

Construction Innovations

During construction, it’s important to eliminate environmentally harmful materials. Encouraging innovation in using recycled materials can be tough but necessary. One landscape architect mentioned the barriers in pushing for more sustainable options.

Once construction is finished, ongoing evaluation is key. Engaging building users ensures that structures remain maintained for optimal climate performance. An architect pointed out that keeping standards high requires ongoing commitment from clients.

Reusing existing buildings instead of demolishing them also helps reduce waste. However, changing long-standing habits in construction can be difficult. Urban designers emphasize the benefits of reusing materials for less waste generation.

Collaborative Efforts

As urban areas evolve, embedding climate action in all decision-making stages becomes crucial. This may involve rethinking how we use existing buildings and updating building policies.

Incorporating climate action can happen at multiple levels:

• Individuals: Professionals can seek out training in climate change.
• Organizations: Firms should review processes to integrate climate action in their projects.
• Universities: Programs should include climate education in their curricula.
• Governments: Policies must mandate climate adaptation and mitigation efforts.

By taking these steps, we can work together to achieve emission reduction goals and protect our cities from climate change risks.
