Steps on the Journey to Net Zero

This chapter discusses the global challenge to reduce greenhouse gas (GHGs) emissions to net zero by 2050. It explains what net zero means and how it is calculated, together with some of the debate around the suitability of the target to maintain global warming levels within ‘acceptable’ boundaries. The chapter then presents some of the opportunities and challenges that transitioning towards net zero will pose to countries and their inhabitants, in terms of changes to policies, products, processes and behaviours that will be required to attain the target. It then discusses the need for a strategy to achieve net zero across different sectors of society and provides a few suggestions of tools and concepts that could be adopted to support the changes necessary, such as planning for change, the Sustainable Development Goals (SDGs), integrated reporting and the circular economy. The chapter concludes with a reflection on the need for the net zero target and how it is our collective responsibility to support the challenging transition to net zero for the benefit of all.
