+
+- **BENCHMARK_ENVIRONMENT**: Selects which environment bounds to use (`local`, `ci`, etc.)
+- **Default**: Uses "local" environment if not specified
+- **CI**: Automatically uses "ci" environment in CI pipelines
+
 Usage:
 ```bash
-# Use default config file
+# Use default environment (local)
 ./run_ducktape_test.py
 
-# Use different configs for different environments
-BENCHMARK_BOUNDS_CONFIG=ci_bounds.json ./run_ducktape_test.py
-BENCHMARK_BOUNDS_CONFIG=production_bounds.json ./run_ducktape_test.py
+# Explicitly use local environment
+BENCHMARK_ENVIRONMENT=local ./run_ducktape_test.py
+
+# Use CI environment with stricter bounds
+BENCHMARK_ENVIRONMENT=ci ./run_ducktape_test.py
+
+# Use different config file entirely
+BENCHMARK_BOUNDS_CONFIG=custom_bounds.json ./run_ducktape_test.py
