Earlier this month, the United Nations held its annual climate change conference, known as COP25, in Madrid. The purpose of this annual global conference is to bring together politicians, policymakers and civil servants from around to world to set out global policy on climate change and agree on binding targets for reducing emissions by 2030 and 2050. The COP21 conference held in Paris in 2015 resulted in a landmark agreement between 195 countries from around the world. At COP21, these 195 countries signed the Paris Agreement, which set out a long-term goal to limit the rise in global temperatures to a range between 1.5°C and 2°C above pre-industrial levels.
