Standard econometric models typically fail to address the risk, ambiguity and multi-dimensionality of sustainability indicators. In comparison, the neutrosophic approach – based on truth, indeterminacy and falsity – provides a solid tool for expressing uncertainty and vagueness with respect to socio-economic assessments. The article creates the ability to use quantitative data together with indeterminacy level (neutrosophic decision making) for evaluating a more complete effort of the sustainability–growth continuum, i.e., beyond only measurable results we evaluate confidence and indeterminacy embedded within them which can be seen by policy makers. Empirical evidence comes from a transition economy characterized by the significant structural reforms and modernization over recent years that clearly shows how strong economic growth can be accompanied by continuing environmental pressures. We compare the official statistics with regards to GDP growth and CO2 emissions per capita that are predicted from 2018 till 2023, in order to analyze whether environmental sustainability develops in line with economic development. Results show that the economy is resilient and growing consistently, while environmental performance is mixed, indicating partial decoupling of growth from sustainability. 2026 2026 466 473 10.54216/IJNS.270237 https://www.americaspg.com/articleinfo/21/show/4166
