That's Alright Then?

The Port of Newcastle in Australia is the world's biggest exporter of coal. Operators of the port claim that the port will be '100% powered by renewable energy by 2040' (https://www.theguardian.com/environment/2022/jan/05/worlds-largest-coal-port-to-be-100-powered-by-renewable-energy). The Port of Newcastle currently exports 165 Mt of coal each year. Although its operators hope that coal will 'only' account for 50% of its business by 2030, the volumes will still be extraordinary. By 'going green', the Port of Newcastle will be only making a tiny, 'local' dent on climate change. Massively exporting emissions is not at all helpful to attempts to limit global heating. Atmospheric carbon dioxide doesn't stay in one place. Is this the most feeble attempt at 'greenwash'?
