Abstract: | The steady-state and nonequilibrium properties of the model of environmental-economic interactions are studied. The interacting
heterogeneous agents are simulated on the platform of the emission dynamics of cellular automaton. The diffusive emissions
are produced by the factory agents, and the local pollution is monitored by the randomly walking (mobile) sensors. When the
threshold concentration is exceeded, a feedback signal is transmitted from the sensor to the nearest factory that affects
its actual production rate. The model predicts the discontinuous phase transition between safe and catastrophic ecology. Right
at the critical line, the broad-scale power-law distributions of emission rates have been identified. The power-law fluctuations
are triggered by the screening effect of factories and by the time delay between the environment contamination and its detection.
The system shows the typical signs of the self-organized critical systems, such as power-law distributions and scaling laws.
