Australia and the UK have recently announced a new Climate and Energy Partnership during the Commonwealth Heads of Government Meeting in Samoa. The agreement focuses on collaborating to accelerate the development of renewable energy technologies, with a particular emphasis on green hydrogen and offshore wind. Both countries aim to harness the economic opportunities presented by the transition to net zero emissions by 2050 and build on their existing cooperation in international climate efforts. Despite this positive development, Pacific Island leaders have raised concerns about the lack of specific details in the partnership, urging for more robust actions to address the pressing climate crisis. Furthermore, a report by the Fossil Fuel Non-Proliferation Treaty Initiative has shed light on the significant role played by the 'big three' Commonwealth countries - UK, Australia, and Canada - in global emissions. These nations have been responsible for a substantial portion of emissions from fossil fuel extraction, despite representing only a small percentage of the Commonwealth's population. The planned expansion of fossil fuel projects, especially in Australia, has faced criticism from Pacific leaders, who view it as detrimental to the survival of their nations. The call for a fossil fuel non-proliferation treaty, led by countries like Vanuatu and Tuvalu, emphasizes the need to halt the expansion of fossil fuels to safeguard vulnerable regions like the Pacific.
