[Economies] need to transform the ways in which energy, transport, food , and housing are produced and consumed (O’Neill et al. 2018). The result should be production and consumption that provides decent opportunities for a good life while dramatically reducing the burden on natural ecosystems. In terms of greenhouse gases, global net emissions should be zero around 2050 – in Europe and the US by around 2040. (Rockström et al . 2017)
