Alain William proposes a unit of environmental impact, the Thunberg (Letters, 1 February). Though designed to achieve desirable outcomes, this seems to have much of the charm of China’s Social Credit System (17 October 2015, p 22).
Likewise, Stewart Reddaway suggests that passenger aircraft should limit the number of premium seats (also in Letters, 1 February). This measure to achieve an environmental goal could also lead us to a dystopia in which, among other things, environmental problems would be impossible to solve. In this case, ask yourself a simple question: who gets the few remaining premium seats?
