From Wikipedia, the free encyclopedia

Climate change in Western Australia affects various environments and industries, including agriculture.

Greenhouse gas emissions

[edit]

By 2022, annual emissions in Western Australia increased by 10% compared to 2005.[1] The state's emissions amounted to 76.23 million tonnes in 2005 compared to 82.64 million tonnes in 2022.[1]

Impacts of climate change

[edit]

Human health

[edit]

Heat-related deaths in Perth may rise by 60% over the period from 2024 to 2050.[2] The incidence of cardiovascular, respiratory and neurological disorders would rise.[3] Potentially food and water security may be compromised.[3]

Flooding

[edit]

Flooding has significantly damaged roads and is expected to increase in frequency.[4][5]

Response

[edit]

Policies

[edit]

In November 2020, the Western Australian government released its long-awaited climate policy, which articulated an aspiration, but no commitment to achieving zero emissions by 2050.[6] The Western Australian government approved a 50-year extension to the North West Shelf gas project in 2024.[7] Public transport was free during the period from December 14, 2024 to February 5, 2025.[8]

Legislation

[edit]

The Western Australian government shelved a bill to legislate a binding 2030 emissions target ahead of the 2025 state election.[9]
