Following this initial set of replies, other authors add comments in subsequent contributions. Söderbaum (2011) frames sustainability economics as a contested notion. He adds the perspective of economic pluralism to the debate and remarks that the scientist is herself a political
actor via her choices of topics, her framing reality or her choice of certain methods. He also proposes to broaden the approach of economics, not relying solely on positivism in economics. According to Söderbaum, the preceding contributions “reflect different ideological
orientations”, with the common denominator that all “advocate some compromise between neoclassical economics and new thinking in sustainability terms” (2011).
