Climate change: World War II-style rationing of petrol, energy and meat could slash carbon emissions
could be tackled with the help of a -style rationing of , meat and the energy people use in their homes, UK scientists say. They claim that this would help countries to slash their greenhouse gas emissions 'rapidly and fairly'. Researchers from the University of Leeds also said that governments could restrict the number of long-haul flights people make in a year or 'limit the amount of petrol one can buy in a month'. They said that previous schemes put forward as a way to fight global warming such as carbon taxes or carbon trading schemes would not work because they favoured the wealthy, who would effectively be able to buy the right to pollute. The experts also made a comparison with the need to limit certain goods as they grew scarce in the 1940s, adding that trying to achieve this 'It is important to highlight the fact that this was not the case for many of those who had experienced rationing. 'It is important to emphasise the difference between rationing itself and the scarcity that rationing was a response to. 'Of course, people did welcome the end of rationing, but they were really celebrating the end of scarcity, and celebrating the fact that rationing was no longer necessary.' The problem with rationing energy, meat and petrol, the researchers point out, is that people might not be as willing to accept it as they would if resources were scarce, because they know there is an 'abundance of resources available'. To tackle this, the researchers said, governments could regulate the biggest polluters, such as oil, gas and petrol, long-haul flights and intensive farming, which would therefore create a scarcity in products that harm the planet. They added that rationing could then be introduced gradually to manage the resulting scarcity. Fellow lead author Dr Rob Lawlor, of the University of Leeds, said: 'There is a limit to how much we can emit if we are to reduce the catastrophic impacts of climate change. In this sense, the scarcity is very real. 'It seems feasible to reduce emissions overall even while the lowest emitters, often the worst off, may be able to increase their emissions not despite rationing, but because of rationing and price controls.' Dr Wood added: 'The cost of living crisis has shown what happens when scarcity drives up prices, with energy prices rising steeply and leaving vulnerable groups unable to pay their bills. 'Currently, those living in energy poverty cannot use anywhere near their fair share of energy supply, whereas the richest in society are free to use as much energy as they can afford.' The experts said one way to roll out the rationing scheme would be to use 'carbon cards', which would work like Dr Lawlor said: 'Many have proposed carbon allowances and carbon cards before. 'What is new (or old, taking inspiration from World War II) is the idea that the allowances should not be tradable. 'Another feature of World War II-style rationing is that price controls on rationed goods would prevent prices from rising with increased demand, benefitting those with the least money.' The experts believe that rationing would also encourage people to move to more sustainable lifestyles, rather than relying on fossil fuels. 'For example, rationing petrol could encourage greater use of, and investment in, low carbon public transport, such as railways and local trams,' Dr Wood said.
