Poland’s energy transition represents a structurally complex case of decarbonization in a coal-dependent economy, where declining hard coal consumption, increasing renewable energy production, growing natural gas use, and continued economic expansion interact within the same energy–economic system. This study assesses the evolution of emission pressure in Poland between 2000 and 2023 using a Fuzzy Multi-Criteria Evaluation (FMCE) framework. The analysis integrates four system-level variables: gross domestic product, hard coal consumption, natural gas consumption, and renewable electricity production, the latter transformed into an inverse fuzzy variable representing insufficient renewable energy penetration. The FMCE-based emission pressure index was constructed using min–max normalization, continuous fuzzy membership degrees, weighted aggregation, and component-level decomposition. The results show that Poland’s emission pressure was highest in the early phase of the analyzed period, especially in 2000–2007, when the energy system remained strongly shaped by coal dependence. The years 2008–2013 formed an unstable transitional phase, while 2014–2018 showed a more stable moderate-pressure configuration. After 2018, the index declined markedly, indicating a shift toward lower emission pressure; however, only selected years reached the formal low-pressure category, which suggests that a stable low-emission regime has not yet been fully established. The decomposition confirms that hard coal was the dominant contributor to emission pressure for most of the period, although its relative contribution declined over time. Renewable energy development increasingly weakened emission pressure, while natural gas played an ambiguous transitional role by partly replacing coal but maintaining fossil-fuel dependence. The study contributes to energy-transition research by proposing an interpretable fuzzy composite index for tracking structural emission pressure over time. The findings underline the need for continued coal phase-down, accelerated renewable energy integration, grid modernization, and careful governance of natural gas as a transitional fuel in Poland’s pathway toward a lower-emission energy system.
