It's not a proposal, it's a thought exercise. But nobody's actually talking about a 100% ban. They're talking about incentives so that people choose an electric car when they buy a new one. And some higher taxes on the use of fossil fuels. And maybe eventually banning new fossil fuel-powered passenger vehicles. If it's anything like Australia, the agricultural industry would be exempt from such taxes. And presumably countries won't tax their own militaries. Whether that's sufficient, I don't know. But it seems like a multilateral agreement, including the US, on both supply and demand side, is the most likely to happen and also have a substantial impact.
