How much can better waste and resource management contribute to mitigating global heating? Prof David C Wilson addressed this question at the Policy Connect Sustainable Resource Forum seminar on October 11 2021. The answer with a high level of confidence is ‘significantly’, perhaps 15-20% of global carbon dioxide (equivalent) emissions. DCW has now written this up as a ‘thought piece’, making the case for prioritising actions at COP26 and beyond to improve waste and resource management and move towards the circular economy. This may be found as both an article and as a video interview on WasteAid’s COP26 hub; as a feature on CIWM’s Circular Online; and as an ISWA guest blog.
