'Net positive', from Positive Development (PD) theory, is a paradigm in sustainable development and design. PD theory (taught and published from 2003)[1][2][3] was first detailed in Positive Development (2008),[4] and detailed in Net-Positive Design (2020).[5] A net positive system/structure would 'give back to nature and society more than it takes' over its life cycle.[6] In contrast, conventional sustainable design and development, in the real-world context of excess population growth, biodiversity loss, cumulative pollution, wealth disparities and social inequities closes off future options. To reverse the overshoot of planetary boundaries, a 'positive Development' would, among other sustainability criteria, increase nature beyond pre-urban or pre-industrial conditions.[7]

^Eco-positive impacts of development must keep pace with human consumption (or ecological footprint) and offset past losses of nature, as defined in Positive Development(Ibid) p. 6.
^A sustainable building should aim to be better for nature/society than no building at all, as well as increase nature beyond native conditions. A rule of reason would be applied as to whether the baseline is pre-industrial or pre-historic, depending on the location and circumstances.
