Let’s flip this idea of looking into the future on its head. Instead of forecasting what is likely to happen, how about backcasting? If we know where we want to be, we can work backwards and plan how to get there!
Tackling climate change and enabling sustainable development dominated global negotiations last year. Successfully addressing these interconnected, mutually dependent challenges is essential, via the development of national long-term strategies for sustainable development and decarbonisation.
So let’s put backcasting into practice: we first need to know where we want to be. In Paris, countries agreed to pursue efforts to limiting global warming to 1.5ºC. To achieve this, a global phasing out of fossil fuels and phasing in of 100% renewable energy will be required by 2050, if not well before. By working back from 2050 to now, we can plan our path to get there individually and collectively, ensuring that we have time to change tracks if needed. The development of national long-term strategies for sustainable development and decarbonisation will provide us essential guidance on the impact of our current policy-making decisions.,
