Reinvigorated by the United Nations Environment Programme (UNEP), a global discussion and national activities on green economy transitions have regained momentum since 2008. The increase in interest is, among other things, due to our growing understanding of the similarity and interlinkages between many of the recent financial, economic, environmental and social crises. The 2008 global financial crisis focused attention not only on the financial losses, and implications for economies, jobs and housing, but also raised questions as to the fundamental imbalance in our economies. The choice of capital allocation - investment in property, fossil fuels and financial assets, rather than in measures to encourage resource efficiency - has created destructive imbalances. A further common element to all these crises is the focus of decision making on short time horizons and trust in what has often proven to be an incomplete evidence base including a lack of proper accounting, for example as regards the cost of climate change and biodiversity.
