This study takes up the phenomenon of disappointment in today's environmental movements. It analyses two distinct streams of environmental movements – neo-environmentalism and the Dark Mountain Project. On the basis of their published written statements, it describes these movements, analyses the opinions of their members regarding possible future developments and examines their ethical motivations. It examines the members’ motivations in terms of three categories – teleological, deontological and virtue ethics – and asserts that each of these contains various expectations, implying (...) varying potential for disappointment. The text's conclusion compares and assesses the attitudes of the members of neo-environmentalism and the Dark Mountain Project, their optimism and pessimism, from the perspective of the philosophers Hans Jonas, Roger Scruton and Romano Guardini.
