The search for solutions to climate change is reminiscent of the tragedy of the commons, where neighbours benefit from shared goods, such as an area of pasture or an irrigation pond, but their overexploitation ends up degrading the shared resource. Faced with a situation that harms everyone involved – in this case, out-of-control greenhouse gas emissions – the actors are unable to reach consensus positions that guarantee the common good, ie. limiting global warming to below 2 ℃.
To address this “tragedy”, the United Nations will host the 27th summit on climate change (COP27) in Sharm el-Sheikh (Egypt) from November 6 to 18.
