This paper concludes a special feature of Sustainability Science that explores a broad range of social value theoretical traditions, such as religious studies, social psychology, indigenous knowledge, economics, sociology, and philosophy. We introduce a novel transdisciplinary conceptual framework that revolves around concepts of 'lenses' and 'tensions' to help navigate value diversity. First, we consider the notion of lenses: perspectives on value and valuation along diverse dimensions that describe what values focus on, how their sociality is envisioned, and what epistemic and procedural assumptions are made. We characterise fourteen of such dimensions. This provides a foundation for exploration of seven areas of tension, between: (1) the values of individuals vs collectives; (2) values as discrete and held vs embedded and constructed; (3) value as static or changeable; (4) valuation as descriptive vs normative and transformative; (5) social vs relational values; (6) different rationalities and their relation to value integration; (7) degrees of acknowledgment of the role of power in navigating value conflicts. In doing so, we embrace the 'mess' of diversity, yet also provide a framework to organise this mess and support and encourage active transdisciplinary collaboration. We identify key research areas where such collaborations can be harnessed for sustainability transformation. Here it is crucial to understand how certain social value lenses are privileged over others and build capacity in decision-making for understanding and drawing on multiple value, epistemic and procedural lenses.

This paper addresses central limitations of ecosystem services and nature's contributions to people (NCP) by developing a novel approach to consideration of intrinsic values of nature. Intrinsic values are seen as bundled with values of ecosystem services and NCP within the Life Framework, an innovative, comprehensive and easy to communicate framework of values. Building on work by John O'Neill, values are conceived of as related to living with, from, in and as the world. These frames are related to but distinct from more formal ethical justifications of intrinsic, instrumental and relational values, which straddle the four Life Frames. Focusing on intrinsic values, we conceive these as ends without reference to humans as valuers, but which nonetheless can be articulated by people. We draw on more-than-human participatory research and post-normal science to promote the articulation and deliberation of perspectives and interests of the more-than-human world by an extended peer community. This clearly differentiates our approach from both rights-based intrinsic value and utilitarian existence value approaches, although it is inclusive of them. The approach is demonstrated by an elaborate integrated marine ecosystem valuation, where we investigate associations between intrinsic and relational values and the four Life frames. The Life Framework, operationalised through the post-normal, more-than-human participatory approach, operationalises articulated intrinsic values in a way that puts them on an equal footing with values of ecosystem services and NCP, providing an opportunity to bridge and reconcile these different types of value through deliberation. This enhances the recognition and procedural justice of valuation, while at the same time retaining the practical advantages that the ecosystem services framework brings.
