Unless you’ve been living under a rock these past couple of years, you’ll no doubt be familiar with the Architects Declare movement, and the flurry of Australian architecture firms that pledged their commitment to becoming carbon neutral, in the wake of that hellish summer of 2019/20. Fast-forward to July 2021, and Fender Katsalidis has just issued the splendid news of its new status—officiated by Climate Active—amongst Australia’s certified carbon neutral architecture firms.

This news got us to thinking: how far have Australian architects come, since pledging en masse to become carbon neutral? What other leading Australian architecture practices can say that they are certified carbon neutral? Further to that, what does it mean? And where do these ‘certifications’ come from? 

What does ‘certified carbon neutral’ mean?

Carbon neutral certifications apply to businesses/organisations that want to, and can, prove that they are actively and genuinely operating with the sustainability of the planet in mind.  When a business or organisation, such as an architecture firm, is certified carbon neutral it means that, its business operations—provision of services included—result in net zero emissions.

Who accredits certified carbon neutral architecture firms?

The authority to accredit architects, as well as other businesses, with a carbon neutral certification doesn’t belong to a single governing body, but a number of organisations. Carbon Reduction Institute (CRI) and Climate Active are two of the foremost Australian accrediting bodies – and each has its own certification programs.

Founded in 2006, CRI has been developing and growing a low carbon economy where organisations and consumers can identify those organisations that take genuine action on climate change. CRI fosters this mission through the NoCO2 Certification Program; a logo certification program that enables organisations to communicate their environmental credentials to the world, at the cost of ongoing membership fees. Since its inception the program has become the most widely recognised and subscribed to climate action certification in Australia. 

Climate Active is an ongoing partnership between the Australian Government and Australian businesses to drive voluntary climate action. Through its Climate Active Carbon Neutral Standard (formerly known as the National Carbon Offset Standard), Climate Active issues its certified carbon neutral stamp of approval to businesses that have achieved a state of producing nil CO2 emissions, at the cost of a licensing fee.
