Abstract
Uncertainties concerning deep-seabed mining relate to the expected impacts on the abyssal benthic and pelagic environment and its ecosystems but also include geopolitical, economic, societal and cultural uncertainty. The uncertain impacts from mining lead to anxiety and a low societal acceptance for the activity and are not the same for everybody at the same time. Hence, uncertainty is an important element of the risk involved in deep-seabed mining. This chapter describes the different risks involved, develops a methodology for risk assessment for the exploitation of marine mineral resources that takes into consideration the state of knowledge and evolving research on deep-sea ecosystems, and informs on possible environmental threshold values in relation to deep-seabed mining operations.

The Capital asset pricing model is a model pricing uncertain future financial claims (e.g., expected profits). This model is an equilibrium model of financial trading, resulting in an equilibrium required rate of return demanding only estimates on the expected risk-free interest rate, the market rate and the investment’s beta value (β). For an overview, see Bodie et al. (2012).

It should be noted that this excludes pecuniary externalities, that is, an externality is present if it affects the productivity of, say, a nearby fishery, not if deep-seabed mining activities affect the profitability of, e.g., terrestrial mining activities.
