Cool Suburbs Tool Released
Cool Suburbs (CS) is Australia’s first heat resilience rating and assessment tool. Developed by Edge Impact together with WSROC and as part of the Greater Sydney Heat Taskforce program initiatives, CS aims to strengthen action on cooling urban areas by guiding evidence-based planning and development decisions at multiple scales across development typologies.
The tool was created through extensive stakeholder engagement, integrating urban heat science expertise, research, and best practices.
The outcome is a voluntary, industry-based performance (rating) tool that assesses place-based urban heat resilience.
It provides a synthesis of urban heat science and practices in an easy-to-use and interpret platform with the goal of supporting improved resilience outcomes.

Global Nature Positive Summit
The inaugural Global Nature Positive Summit was held in Sydney, Australia from October 8-10, 2024, bringing together over 900 delegates from government, business, research, environmental organisations, civil society, and Indigenous groups.
Co-hosted by the Australian federal and New South Wales State governments, the summit aimed to accelerate collective action to drive investment in nature and strengthen efforts to protect and repair the environment.
Key themes included: realising commitments under the Kunming-Montreal Global Biodiversity Framework; exploring ways to unlock private sector investment in nature; and, developing metrics to measure progress towards nature positive goals.
While the summit showcased some government initiatives and innovative solutions, it also faced criticism from environmental groups who argued that current policies remain largely "nature negative" despite the rhetoric. The event was seen as an important step in elevating nature and biodiversity alongside climate change as critical global challenges requiring urgent action.
Edge’s very own Alison Rowe (Global CEO) and Sarah Day (Nature Advisory lead) were invited to attend the summit.
Sarah’s five key takeaways from the Global Nature Positive Summit:
1. Engagement isn’t a metric
Engagement isn't something that can be ticked off, it must be collaborative, must inform the way we characterise the problem in the first instance, and must work towards outcomes that support the objectives of all engaged.
2. A nature positive economy isn’t an option, it’s our only option
To achieve the outcomes needed at the scale required, we're talking about a systemic change to how we operate as an economy, a society, as businesses - and to achieve this we need strong leadership and governance, from Government, businesses, and demand from society. This is about shifting what we value - we currently primarily value nature when it's dead - a piece of wood, a piece of meat - rather than the role of the tree in the forest, or the fish in the sea.
3. We need to change our relationship with nature
We need to change our relationship with nature and recognise how inextricable our relationship is. Starting by asking 'What kind of ancestors do we want to be?' and 'If Mother Nature was at the Board table, what would she say?'
4. Local impact, local issue, local solutions - global awareness and problem solving
While nature is hyper regional and we need to look locally when crafting solutions, there's a lot for us to learn from experiences nationally and globally.
5. Disclose, and…
Disclosure is an element of this nature journey, but cannot be the only focus. Action must be prioritised if we have any chance of achieving the scale of change required.

Paris Unplugged: From Car Capital to People’s Paradise
Paris, the City of Light, is now a beacon of sustainable urban living under Mayor Anne Hidalgo’s bold vision, transforming streets and reclaiming space from cars.
Here are 7 surprising ways Paris is unplugging from the car:
1. Pedal Power: Over 1,000km of cycling routes, including 350km of protected cycleways, have led to a 71% increase in cycling traffic since 2019.
2. Seine Transformation: Highways along the Seine are now vibrant pedestrian areas and bike paths, creating a stunning public space.
3. Slow and Safe: A 30km/h speed limit prioritizes pedestrian and cyclist safety.
4. Parking Reduction: Paris is removing 72% of on-street parking, reclaiming over 65 hectares for people-friendly spaces.
5. School Streets: 205 “school streets” restrict car access around elementary schools, enhancing safety and walkability.
6. SUV Surcharge: A recent referendum tripled parking charges for large vehicles, making it costly to bring SUVs into the city center.
7. 15-Minute City: Paris is creating self-sufficient neighborhoods where essentials are within a 15-minute walk or bike ride, reducing car travel.
These radical changes haven't been without controversy, but the results speak for themselves. Car ownership in Paris has fallen from 60% to 35%, and carbon emissions have been cut by about 20%.
The City of Light is truly becoming the City of Life, showing the world that fewer cars can mean a brighter future for everyone.
Green Lungs of the City: Yiwu's Innovative Urban Ecological Project
In 2019, the municipal government of Yiwu, China, launched the Green Lungs of the City Project (GLCP), an ambitious nature-based initiative to expand green spaces, reduce environmental strain, and strengthen climate resilience. At its core is a central forest-wetland park, featuring green corridors, wetland restoration, urban parks, and blue infrastructure. Together, these elements enhance biodiversity, water management, and public health.
The GLCP improves air and water quality, manages stormwater, connects ecosystems, and reduces urban heat, while also creating green jobs and recreational spaces. This collaborative effort—uniting local government, NGOs, community groups, and researchers—serves as a model for integrating nature-based solutions in urban planning, demonstrating how cities can balance growth with environmental and social sustainability.

A-Tree-Citation
This issue’s a-tree-ciation is inspired by Dr Jenni Garden's travels to the US which occurred one year ago this month.
During this trip I visited California where I was treated to a tour of Big Basin Redwoods State Park (BBRSP). This park is home to the largest continuous stand of ancient coastal redwoods (Sequoia sempervirens) south of San Francisco – the tallest tree species in the world, and among the longest lived, with some trees living more than 2,000 years!
The Coast Redwood's ability to create its own ecosystem, supporting diverse wildlife and even other plants growing on its massive branches, symbolizes nature's interconnectedness and reminds me of the profound impact a single organism can have on its surroundings.
Sadly, the BBRSP was devastated by the August 2020 Lightning Complex Fire which burned more than 97% of the 7,366ha forest. When I visited in October 2023, these ancient trees were covered in regrowth showing their remarkable resilience in the face of environmental challenges.
