While winter sport has always adapted to weather variability, climate change is shifting the baseline. Research commissioned by the International Olympic Committee has found that as global temperatures rise, the number of climatically reliable host locations is expected to decline significantly over coming decades. Under mid-range emissions scenarios, only around half of previously suitable host regions may remain viable by the 2050s

Milano Cortina 2026 has committed to a sustainability strategy that is holistic, concrete and progressive, embedding environmental responsibility across planning, delivery and long-term legacy. Central to this approach is the adoption of circular economy principles, designed to minimise waste, extend asset life and deliver lasting benefits for host communities.

As sport continues to navigate climate impacts and environmental expectations, the lessons from the Australian Open can help guide both elite and community sporting organisations towards more sustainable operations and events.

From community grounds to elite stadiums, our sporting systems rely on healthy land, water and communities to thrive. Yet climate change is increasingly disrupting the way sport is played, managed and experienced, raising an urgent question for the sector: can Australian sport ever be environmentally sustainable?

Community tennis clubs across Melbourne are proving that sustainability can deliver real, practical benefits both on and off the court.

Sports Environment Alliance (SEA) is delighted to welcome Calisthenics Victoria as the newest member of the SEA network.

As the governing body for calisthenics in Victoria, Calisthenics Victoria is committed to creating a more sustainable future for its sport and community.

As stadiums, clubs, and major events prepare for another massive summer of sport, new research released through Freedom of Information has delivered the clearest evidence yet that reuse must become the dominant approach to food and beverage packaging.

At SEA, we believe collaboration is key to lasting impact. The example set by Golf Australia and Golf Ball Recycling shows that practical, measurable sustainability is within reach — and that golf can be a driver of innovation, not just recreation.

For many Victorians, the long weekend leading up to Cup Day is a time to celebrate — a chance to gather with friends and family and enjoy one of Australia’s most iconic sporting and cultural traditions.

But behind the glamour, fashion, and thunder of hooves on the track, the Victoria Racing Club (VRC) is working hard to ensure that this iconic event is also leading the charge on sustainability.

As Australia prepares for the Brisbane 2032 Olympic and Paralympic Games, there’s a generational opportunity to design sporting precincts where circular systems are built in, not bolted on. Refunds from containers could help fund community sport, environmental programs and infrastructure — showing how sustainability can underpin major events.

A new BBC Sport article has highlighted the power of grassroots clubs to “change the country” in the face of the growing climate crisis - a message that strongly echoes the mission of the Sports Environment Alliance (SEA).

Cricket Victoria has announced a significant partnership with Victoria’s Container Deposit Scheme (CDS), aiming to enhance sustainability within the sport. This collaboration aligns with the global Green Sports Day 2025, underscoring the commitment of Australian sports to environmental responsibility.

Athletes Can Lead the ‘Climate Comeback’ On and Off the Field

Many of the nation’s most iconic sporting venues have confirmed their commitment to Australia’s Green Sports Day 2025, a global celebration of sport’s collective action on climate.

South Australia’s coastline is experiencing one of the most significant algal blooms in decades, stretching more than 150 kilometres from the Fleurieu Peninsula to Gulf St Vincent.

Global environmental initiative comes to Australia as the sporting community rallies behind #noplanetnoplay

Guest columnist Matt Rendell, former ITV Tour de France broadcaster, pulls no punches in opinion piece, written in collaboration with the Cool Down Network.

Grassroots sport has long been the heartbeat of communities, but new research highlights just how exposed it is to the realities of a changing climate.

We’re proud to share that Sports Environment Alliance has been shortlisted in the ‘Community Initiative’ category at the Sport Positive Awards 2025 for our project Reducing Community Waste: A Team Sport.

Climate change may not just bring heat - it could bring hail storms the size of tennis balls. For sport and community across Australia, being prepared isn’t an option - it’s essential.
