+    Scoring Guide:
+    - 90-100 (Excellent/Leader): Demonstrates exceptional environmental stewardship, innovative green practices, and minimal negative impact across all factors. A true leader in sustainability.
+    - 70-89 (Good/Above Average): Shows strong environmental practices with notable positive attributes and efforts to reduce impact. Generally a good choice for sustainability.
+    - 40-69 (Average/Acceptable): Meets basic environmental considerations but has significant areas for improvement. Represents typical industry practices without outstanding sustainable features.
+    - 0-39 (Poor/Concerning): Significant environmental concerns, unsustainable practices, or a clear lack of attention to environmental impact.

+    Examples to guide scoring perspective:
+    - Product: "Electronic smartphone with aluminum body, manufactured in China, typical global distribution for sales in Europe."
+        Typical Score Range: 50-65 (Reasonable for modern electronics with some recyclable components and efforts, but significant global transport, energy consumption during use, and complex end-of-life disposal.)
+    - Product: "Local handmade wooden furniture using sustainably harvested, certified wood, finished with non-toxic oil, sold within 50km of production."
+        Typical Score Range: 85-95 (Excellent material choice, minimal transport, durable product designed for longevity, non-toxic finish, often supports local economy.)
+    - Product: "Single-use disposable coffee cup made from virgin paper with a plastic lining, widely distributed via international shipping."
+        Typical Score Range: 20-35 (Poor due to single-use nature, material composite making recycling difficult, high transport, and significant waste contribution.)

     Here are some examples of products and their potential scores to guide your assessment, aiming for higher scores where appropriate:
 
-    * **"Electronic smartphone with aluminum body, manufactured in China"**: Likely Overall score in the range of 50-65. While it has some recyclable materials, manufacturing and transportation in a global supply chain contribute to a moderate footprint.
-    * **"Local handmade wooden furniture using sustainable forest wood"**: Likely Overall score in the range of 85-95. This product benefits from local production, renewable resources, and often a longer lifespan.
-    * **"Single-use plastic water bottle produced with virgin plastics"**: Likely Overall score in the range of 10-25. High environmental impact due to non-renewable materials, single-use nature, and pollution potential.
