It is not the capital of Australia, but it is undoubtedly its most iconic city, with its spectacular Opera House and very long beaches, a destination for tourists and surf lovers.

Sydney is a modern city (in every sense, since it has "only" existed since 1788!) which is profoundly renovating its urban transport system, with the aim of becoming a zero-emission city and reducing the number of cars in circulation.

As? Through an ambitious plan that puts the environmental sustainability, social inclusion and cultural offer for citizens. One of the highlights of this program is public transport, and the key project in Sydney's vision for a green mobility is the new Metro West, set to become the largest urban train network in Australia.

Clean energy and recycled materials for new routes

Part of the Sydney Metro City & Southwest line will open in 2024, while the new Sydney Metro-Western Sydney Airport line will serve Greater Western Sydney and the new Western Sydney International (Nancy-Bird Walton) Airport by 2030.

The three lines under construction, together with the existing one, will run over 113 kilometers and 46 stations, carrying 44.000 passengers per hour (against the current 24.000).

A 60 percent increase in the number of trains passing through the city center is expected, from the current 120 trains an hour to 200.

The aim is to make it easy and convenient for citizens to move around the city, leaving their private car at home and reducing the number of vehicles in circulation.

The western area is the beating heart of the Australian city: in fact, it also includes the Central Business District (the financial district), the Olympic park and the popular districts of Westmead and Parramatta.

Il Sustainability Plan that the Sydney Metro published in recent months illustrates how 95 percent of the excavated materials of the new line will be entirely recycled and all the water used in the construction phase will be reused. Furthermore, priority will be given to recycled materials and only electricity from renewable sources will be used. 

“We know it is imperative to address the growing pressures of climate change, depletion of natural resources and social inequalities”Said Peter ReaganCEO Sydney Metro.

“We will continue to work with industry to ensure Sydney Metro follows best practice at all stages of the project lifecycle, putting sustainability first.”

The vision for 2050: a sustainable and connected city

The City of Sydney has ambitious goals to promote the sustainable transport, and it will not be limited to just making the subway "greener".

The New South Wales State Government (where Sydney is located) has allocated A$41 million to modernize the transport network over four years, with a particular focus on sustainable mobility.

Key concepts to achieve this goal are the "30-minute cities" and "15-minute neighborhoods", which will allow citizens to easily and quickly access services, schools, jobs and leisure areas.

“Making these commutes easier and more attractive will revitalize local centers by increasing foot traffic and supporting local economies”. it reads on New South Wales Government website.

“It will also promote sustainability by reducing vehicle emissions and noise, increasing cultural offerings and creating the feeling of a more connected neighborhood and community.”

According to the guidelines of the plan for the sustainability city ​​government, by 2050 or sooner, Sydney will have an extensive network of walking and cycling routes and will use only zero-emission vehicles.

The city is also committed to offering affordable housing, achieving a recycling rate of more than 90 percent and a minimum overall green cover of 40 percent (with 27 percent tree cover).

In short, the city is actively working to promote a healthy lifestyle, reduce its environmental impact and create lively and welcoming public spaces for all its inhabitants, rigorously green.

A metropolis in transition and transformation

Sydney's strategy for environmental sustainability fits into a global context where cities around the world are dealing with the growing effects of climate change.

In Australia, in particular, the consequences of devastating fires, prolonged droughts and heat waves have made evident the urgency of adopting concrete measures to protect the environment and secure a sustainable future.

Sydney isn't the only city taking significant action to address this challenge. Around the world, metropolises are transforming, recognizing the need for sustainable approaches in various sectors.

From the promotion of slow mobility to the creation of urban green spaces, cities are beginning to conceive of themselves as living organisms that must adapt and survive in a context of climate change.

At the same time, companies are also working to offer green solutions for urban construction, such as environmentally friendly flooring, Solid Earth, which combine performance and sustainability.

This global effort offers a ray of hope for the future of cities. Concrete and innovative measures are being taken to mitigate the environmental impacts, protect natural resources and improve the quality of life of citizens.

These efforts bring us ever closer to a world where the sustainability it is at the heart of urban development and community prosperity.
