Development drives greenhouse gas emissions through increased consumption of fossil energy, increasing populations, industrial production, and increasing consumption. It also shapes the way societies are able to respond to climate change and other challenges. Climate change as caused by greenhouse gases emitted as a result of development can undermine that same development. This chapter looks at how to get out of this vicious circle. The solution can only be found if development objectives are seen as the starting point. Alleviating poverty and providing people with decent living conditions has to remain central. The way to get there can and must be changed. Integrating climate change into development decisions and making development more sustainable is the way to go. But what does that mean in practice and how easy is it to reconcile conflicting priorities? These are some of the issues that this chapter will investigate.
