Abstract:
This paper presents a comparative analysis of the spatio-temporal variability of anthropogenic methane (CH₄) and carbon dioxide (CO₂) emissions at both European and national scales, using data from the EDGAR database (Emissions Database for Global Atmospheric Research) for the period 1970–2024. The methodology is based on the application of Empirical Orthogonal Functions (EOF), which decompose spatio-temporal fields into dominant modes of variability. For both compounds, the analysis is carried out at two geographic scales: Europe and Romania. Additionally, CO₂ emissions are treated separately according to their origin — fossil (long-cycle carbon) or biogenic (short-cycle carbon).The results reveal that Romania exhibits a high degree of spatial homogeneity, with the first EOF mode explaining 88–98% of CH₄ emission variability and up to 90% for CO₂ at the national scale. At the continental scale, both greenhouse gases highlight 1989–1990 as the dominant structural turning point reflecting the post-communist industrial collapse in Eastern Europe.
