This study proposes a new method of graph computing for environmental
economics. We apply a weighted graph model that reproduces the structure of SOx
emission–deposition tables. Our data apply scientific and technical data on emissions,
atmospheric processes, and effects on the environment of sulfur oxides from
the European Monitoring and Evaluation Program of the long-range transmission of
air pollutants in Europe. Our graph metrics consider both the activity and the
amount of pollution for each polluter. The results show the contribution of oxidized
sulfur emitted from one country and deposited to another. The most influential node
of the country-to-country blame network is tracked using indicators of centrality.
Exploring options and metrics for ranking the blame for SOx pollutants, we depict
the degree of the responsibility for SOx depositions in EU countries graphically.
