The water sector in the state of Victoria, Australia, contributes around 25% of the greenhouse gas emissions for which the state’s Government is responsible. The state’s 19 water utilities have each committed to achieving net zero emissions by or before 2050. While their primary focus is on reducing direct emissions and those associated with energy use, some utilities will need to offset unavoidable emissions associated with wastewater treatment.
Jacobs were engaged to work with Victoria’s water sector to undertake the Catchment Carbon Offsets Trial. The trial explored the use of offsets to help achieve emissions reduction objectives, while providing other catchment-based environmental, social and/or cultural benefits, that complemented State government or regional policies and strategies on climate change, water, watershed management and biodiversity. Concepts developed in the trial were tested in a case study with Wannon Water, a regional water utility servicing south-western Victoria. Several catchment carbon offsets designs were developed and evaluated. They showed that it would be possible to satisfy Wannon Water’s carbon offset requirements (~8000 t CO2e/y), while cost-effectively improving climate resilience, water quality, biodiversity values and recreational and cultural values.
The trial also developed design and evaluation tools to implementation of the catchment carbon offset concept by other water utilities.
