Working together to build a better future

Carbon neutral since 2011, the City of Sydney was the first government in Australia to achieve certification under the national carbon offset standard.

We are assessed each year on our carbon neutral commitment, and since 2006 have reduced our own greenhouse gas emissions by 26%.

Across our local area, emissions today are 21% below 2006 levels. This is despite strong economic growth and expanding numbers of workers and residents in the city.

Our work to reduce emissions is part of our larger Sustainable Sydney 2030 strategy.

Our vision for a green, global and connected city will transform the way we live, work and play.


  • Retrofits: Upgrading our most resource-intensive buildings. So far, 45 large buildings have been retrofitted with a host of energy efficient technologies, including movement sensors, solar panels and LED lighting. This has driven down electricity use in the buildings, which include Waranara Early Education Centre and Redfern Oval, by 41% since 2006.
  • Future proofing our new buildings: Our new Alexandra Canal depot is powered by more than 1,600 solar panels and features Sydney’s first Tesla Powerpack battery.
  • Lighting: Replacing 6,604 City -owned street and park lights with energy efficient LED lighting has slashed emissions by 48% and is saving almost $800,000 each year.
  • Trigeneration: Our rooftop trigeneration system produces low-carbon energy to power, heat and cool Sydney Town Hall and Town Hall House. Operating since October 2016, the system will cut carbon emissions by an estimated 40,000 tonnes over its 30-year lifetime.
  • Installing solar: We are installing solar panels on around 35 sites. These include Sydney Park Pavilion, Paddington and Glebe town halls, as well as libraries, community centres, depots and other public facilities.


Our programs are helping building owners, occupants and visitors in residential apartment, commercial office, and accommodation and entertainment communities, to save money while driving down emissions. These include:


We are proud to be part of a network of other cities taking bold action on climate change. We are an active member of C40 Cities Climate Leadership GroupCarbon Neutral Cities Alliance and the Cities Power Partnership, leading the way towards a healthier and more sustainable future. We report yearly to CDP and are a signatory of the Global Covenant of Mayors for Climate & Energy.

To support the transition to net zero energy, we're working with developers, construction companies, planning and environmental sustainability consultants, and local and state government planners to create planning pathways to net zero buildings.

We're a founding member of the Business Renewables Centre Australia. The centre is an information hub and platform that will simplify, streamline and accelerate corporate purchasing of large-scale wind and solar energy.
