An evaluation of decoupling in the Hungarian economy

Key findings from this study

• The study found that strong decoupling occurred in sectors B, C, D, and E, where emissions decreased while economic output grew.
• The authors report that Hungary's economy demonstrated a trend toward absolute decoupling nationally in recent years, with GVA expanding as emissions stabilized or contracted.
• The researchers demonstrate that sector T exhibited unsustainable growth patterns characterized by expansive negative decoupling.

Overview

The study examines decoupling between economic growth and greenhouse gas emissions in Hungary from 1995 to 2022. The researchers applied the Tapio decoupling model and Mann-Kendall trend test to assess relationships between Gross Value Added and emissions across economic sectors.

Methods and approach

The Tapio decoupling elasticity coefficient quantified the relationship between economic activity and environmental impact. The Mann-Kendall trend test detected monotonic trends in GVA and emissions, establishing statistical significance and directional change across sectors.

Results

Sectoral decoupling patterns varied substantially. Strong decoupling emerged in sectors B, C, D, and E, where emissions declined despite economic expansion, driven by technological improvements and structural transformation. Weak decoupling characterized sectors A, F, G, and Q, with emissions rising slower than GVA but not achieving full separation. Sector T demonstrated expansive negative decoupling, indicating growth that increased environmental pressure unsustainably.

Nationally, recent years showed progression toward absolute decoupling, with GVA rising while emissions stabilized or declined. The Mann-Kendall test confirmed consistent economic growth across all sectors but revealed divergent emission trajectories. Sectors B and E achieved substantial emission reductions, whereas sectors A and T recorded increases.

Implications

The findings demonstrate heterogeneous progress toward environmental sustainability across Hungary's economy. Sectors with strong decoupling provide evidence that technological advancement and structural reorganization can decouple growth from emissions, though achievement remains uneven across the economy.

The emergence of absolute decoupling at the national level suggests Hungary has shifted toward more sustainable growth patterns in recent years. However, persistent weak decoupling and negative decoupling in specific sectors indicate incomplete transition and require targeted policy intervention to accelerate emission reductions in underperforming sectors.
