The water sector is the largest government greenhouse gas emitter in Victoria, but the water sector is determined to turn the tide for World Water Day.

World Water Day (Sunday 22 March) this year acknowledges the link between water and climate change.

The water sector, which includes the Water and Catchments Group of DELWP, water corporations and catchment management authorities (CMAs), emits around 1 million tonnes of greenhouse gas each year - around a quarter of all Victorian government sector emissions.

To combat this, the sector has developed a mitigation plan to reduce emissions by 42 per cent by 2025 and is using the latest climate science to prepare for changes in climate and reductions in water availability.

The Victorian Government is investing in research to improve our understanding of changes in climate and water resources, led by DELWP’s Hydrology and Climate Science team.  

Under the earlier Victorian Climate Initiative, DELWP partnered with the Bureau of Meteorology and CSIRO to deliver robust guidelines for water corporations and CMAs to assess the impact of climate change on water supplies.

The sector must provide reliable services for a growing population in an increasingly challenging climate with more extreme climatic events, less rainfall, and a possible 50 per cent reduction in streamflow by 2065.

Climate change is a core consideration in Water for VictoriaVictoria’s long-term direction for managing Victoria's water resources.

There has been significant progress to ensure our water system is modern, efficient, innovative, future-focused and affordable under climate change.

But there’s more work to be done.

Victoria’s Pilot Water Sector Climate Change Adaptation Action Plan (PDF, 4.6 MB), led by DELWP’s Climate Adaptation team, is shaping the transformation to ensure climate change is a key consideration in all relevant business decisions.
