Ending poverty and addressing climate change are the two defining issues of our time. Both are essential to achieving sustainable global development. But they cannot be considered in isolation. This report brings together these two overarching objectives and explores how they can be more easily achieved if considered together. It demonstrates the urgency of efforts to reduce poverty and the vulnerability of poor people in the face of climate change. It also provides guidance on how to ensure that climate change policies contribute to poverty reduction and poverty reduction policies contribute to climate change mitigation and resilience building. We need good, climate-informed development to reduce the impacts of climate change on the poor. This means, in part, providing poor people with social safety nets and universal health care. These efforts will need to be coupled with targeted climate resilience measures, such as the introduction of heatresistant crops and disaster preparedness systems. The report shows that without this type of development, climate change could force more than 100 million people into extreme poverty by 2030. But with rapid, inclusive development that is adapted to changing climate conditions, most of these impacts can be prevented.
