Mitigation Pathways Compatible with 1.5°C in the Context of Sustainable Development

This chapter assesses mitigation pathways consistent with limiting warming to 1.5C above pre-industrial levels. In doing so, it explores the following key questions: What role do CO 2 and non-CO 2 emissions play? {2.2, 2.3, 2.4, 2.6} To what extent do 1.5C pathways involve overshooting and returning below 1.5C during the 21st century? {2.2, 2.3} What are the implications for transitions in energy, land use and sustainable development? {2.3, 2.4, 2.5} How do policy frameworks affect the ability to limit warming to 1.5C? {2.3, 2.5} What are the associated knowledge gaps? {2.6}
