+
+        This factory method resolves credentials from environment variables,
+        providing a convenient way to create a workspace without explicitly
+        passing credentials.
+
+        Environment variables used:
+            - `AIRBYTE_CLOUD_CLIENT_ID`: Required. The OAuth client ID.
+            - `AIRBYTE_CLOUD_CLIENT_SECRET`: Required. The OAuth client secret.
+            - `AIRBYTE_CLOUD_WORKSPACE_ID`: The workspace ID (if not passed as argument).
+            - `AIRBYTE_CLOUD_API_URL`: Optional. The API root URL (defaults to Airbyte Cloud).
+
+        Args:
+            workspace_id: The workspace ID. If not provided, will be resolved from
+                the `AIRBYTE_CLOUD_WORKSPACE_ID` environment variable.
+            api_root: The API root URL. If not provided, will be resolved from
+                the `AIRBYTE_CLOUD_API_URL` environment variable, or default to
+                the Airbyte Cloud API.
+
+        Returns:
+            A CloudWorkspace instance configured with credentials from the environment.
+
+        Raises:
+            PyAirbyteSecretNotFoundError: If required credentials are not found in
+                the environment.
+
+        Example:
+            ```python
+            # With workspace_id from environment
+            workspace = CloudWorkspace.from_env()
+
