Anything where there is a need for the correction of perceived market failures by considering the value of public goods in transactions, e.g. climate change, pollution, water resources, agriculture, forestry. This has been an approach to reducing the impact of climate change for some time now and is becoming increasingly important in evaluating the environmental impact of projects, in the Payment for Ecosystem Services (PES) and in taxing / fining pollution. The public setor is in incresing need of environmental economists: in the UK: DECC, DEFRA and possibly DFID. Internationally, the World Bank, IMF, IFC are increasingly recruiting for environmental evaluation of a range of projects (energy, agriculture, water resource mgmt, land mgmt, desertification, climate change mitigation), PES, REDD projects, and we should not forget UNEP, UNFCCC, European Environment Agency. Then there are a number of NGOs (WWF, Conservation International, IUCN), think tanks or research institutes (ODI, IIED, IISD, SEI, New Economics Foundation) or consultancies in need of environmental economists (Cambridge Economic Policy Analysts, KPMG and the rest). Then there are the perhaps more financial areas, working in carbon markets, though that is not such a great area right now. Still some NGOs/foundations are looking at how it could be improved (Carbon Trust, Gold Standard). Anyone like to add anything to that??
