The report is organized into six chapters, including this introduction. Chapter 2 assesses the trends inglobal GHG emissions and G20 member progress towards their Cancun Pledges in 2020 and their NDCs in 2030. In addition, it considers the potential implications of COVID-19 on G20 emissions projections. Chapter 3 updates the assessment of the likely emissions gap in 2030. Furthermore, the chapter provides a preliminary assessment of how COVID-19 and associated rescue and recovery measures may impact global GHG emissions in 2030 under various scenarios. The chapter then looks at the implications of the emissions gap on the feasibility of achieving the long-term temperature goal of the Paris Agreement. Chapter 4 assesses the size and extent to which COVID-19 fiscal rescue and recovery measures to date can be said to support low-carbon or high-carbon development. It also outlines emerging lessons for governments in the pursuit of a low-carbon economic recovery. The two final chapters of this year's report cover areas that have received limited attention in previous Emissions Gap Reports, but that receive much international attention and have been particularly affected by COVID-19. Chapter 5 looks at the trends and opportunities for decarbonizing the shipping and aviation sectors, with a particular focus on international transport. Finally, chapter 6 assesses the role and opportunities for reducing GHG emissions through lifestyle and behavioural change, paying particular attention to inequalities in per capita emissions within and across countries and the systemic changes necessary to support and induce lifestyle change.
