One of the starkest warnings about the environmental cost of division comes from a major new report from the International Energy Agency (IEA), which runs the rule over progress in clean power, hydrogen, steel, road transport and agriculture.We realise that, in the context of current global events, some of that stuff is much harder.” Spiralling energy prices have led to an “increasingly crowded” field of clean energy R&D projects across countries, said Luciano Martini, director of a joint project between Italy, China and the UK that aims to demonstrate 100% renewable energy power systems.In the autumn Washington banned its leading chipmakers from exporting artificial intelligence-capable semiconductors to China, and cut off the means for Beijing to develop homegrown alternatives.The US and China, the world’s biggest greenhouse gas emitters, agreed to restart climate change talks after Beijing halted them in retaliation for House speaker Nancy Pelosi’s visit to Taiwan in August.“If you want to maximise acceleration from that, you also need knowledge sharing and cooperation.” Mission Innovation set targets for countries to double green technology R&D in certain areas between 2015 and 2020."
