Assessing the sustainability impacts of frugal innovation – A literature review

Frugal innovation can help to foster sustainability and address global challenges, like building economic growth, addressing various social needs, and protecting the environment. However, if one wants to measure the sustainability impacts of frugal innovation or enable companies to make empirically informed decisions between frugal and alternative innovation, the question of how to assess these empirical impacts arises. The main objectives of this paper are the identification of approaches and indicators for assessing the sustainability impacts of frugal innovation and the analysis of empirical findings relating to prior assessments. To this end, a systematic literature review was conducted, which identified 15 texts, and a qualitative content analysis was employed to evaluate their contents. From these analyses two main approaches for assessment emerged. First, the assessment based on the triple bottom line or the dimensions of sustainability (ecological, social and economic). Second, assessment against the Sustainability Development Goals. In the identified texts, the sustainability dimensions are preferred over the Sustainable Development Goals for assessing the sustainability impacts of frugal innovation. From the 15 identified texts, 13 use qualitative indicators and two quantitative (conceptual) indicators. To answer the research question of the paper, a set of 47 qualitative indicators relating to integrated dimensions of sustainability for the assessment of the sustainability impacts of frugal innovation is proposed. In addition, this paper presents new insights relating to the empirical evidence of sustainability impacts of frugal innovation. Approximately 60% of 334 empirical findings from 70 different cases related to the Sustainable Development Goals contribute to the five (socially and economically focused) SDGs 8, 3, 10, 12, and 9. After a transformation to the Triple Bottom Line, these findings contribute predominantly to the economic and social dimensions (in each case 45%), and only slightly to the ecological dimension (the remaining 10%). In turn, 164 empirical results from 77 different cases related to the Triple Bottom Line show an almost similar contribution to all three sustainability dimensions with a small lead of the economic dimension. Nonetheless, in the opinion of the author, these findings confirm other studies, that from an empirical perspective, frugal innovation can be described as inherently socially and economically sustai
