Despite being currently voluntary in Australia, operational carbon neutrality is increasingly being considered for buildings as climate change continues to be a pressing global issue. Projects targeting carbon neutral certification manages greenhouse gas emissions in operation by considering Scope 1, Scope 2, and Scope 3 emissions. Green Star Performance offers a viable pathway to obtain a Carbon Neutral Certification. This requires early engagement and close collaboration amongst project team and stakeholders for all aspects of building fabric, HVAC, lighting, controls and optimisation, waste operations, water management, metering and monitoring, renewables, offset opportunities, etc.

Zero Energy is a closely related initiative that considers offsetting electricity consumption from building operations with generation from renewable energy sources, and elimination of on-site combustion. Certification schemes such as the Zero Energy Certification from the International Living Future Institute offers a recognition opportunity for a highly energy efficient and sustainable building.
