Australia and the United Kingdom have committed to increasing the global supply of critical minerals essential for a greener world economy. Australia is the leading producer of raw lithium and other crucial materials for electric cars, new energy equipment, and advanced communications. However, with China’s domination of purified critical minerals and rare earths, the two allies have decided to collaborate to ensure supply chain stability. The UK Minister for the Indo-Pacific, Anne-Marie Trevelyan, signed a letter of intent with Australian Resources Minister, Madeleine King, in Perth to future-proof supplies. The International Energy Agency predicts that the need for battery technology and electronics will quadruple by 2040. Sovereign processing, manufacturing, investment ties for projects, research and development, and other measures are covered by the statement of intent. They aim to enhance skills, collaborate with allies, and promote high environmental, social, and governance (ESG) standards. Later this year, Australia will release its critical minerals strategy, a key aspect of its commitment to achieving net-zero emissions by 2050.
