Global military expenditure rose by 3.6% (from 2018) to reach $1.917 trillion in 2019, according to data compiled by The Stockholm International Peace Research Institute (SIPRI), released in April
Though it notes that the data for the UK is ‘highly uncertain’, SIPRI lists UK’s expenditure as $48.7bn, which would make it the eighth biggest spender in the world after the US ($731.8bn), China ($261.1bn), India, Russia, Saudi Arabia, France and Germany.
Last year the investment bank Morgan Stanley estimated that the world would need to spend $50 trillion by 2050 in order to cap global warming at a rise of 2°C.
