-    Consider these factors:
-    1. Carbon emissions intensity
-    2. Recyclability of materials
-    3. Manufacturing sustainability
-    4. Transportation impact
-    5. Product longevity
-    6. End-of-life disposal
+    **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.
     
-    Provide:
-    - Overall score (0-100, where 100 is most sustainable and 0 is least sustainable)
-    - Category breakdown
-    - Improvement recommendations
+    **Consider these factors, focusing on identifying and rewarding positive environmental performance:**
+    1.  **Carbon Emissions Intensity:** Evaluate how effectively greenhouse gas emissions are minimized throughout the product's lifecycle (from raw materials to disposal).
+    2.  **Material Sustainability:** Assess the use of recycled, renewable, non-toxic, or sustainably sourced materials, and the efforts to reduce reliance on virgin resources.
+    3.  **Manufacturing Practices:** Examine the adoption of clean production methods, energy efficiency, water conservation, and waste reduction during the manufacturing process.
+    4.  **Supply Chain & Transportation Impact:** Analyze the efficiency and environmental footprint of sourcing raw materials and delivering the finished product (e.g., local sourcing, optimized logistics).
+    5.  **Product Durability & Longevity:** Determine if the product is designed for an extended lifespan, repairability, and reusability, thereby reducing premature obsolescence.
+    6.  **End-of-Life Management:** Review the effectiveness of strategies for recycling, composting, safe disposal, or circular economy integration once the product's useful life ends.
+    
+    **Provide:**
+    -   **Overall Score (0-100):** State the numerical score clearly.
+    -   **Justification:** Explain the score by highlighting the product's **strengths and positive environmental attributes** that contributed to its rating. Also mention any significant weaknesses where applicable.
+    -   **Improvement Recommendations:** Offer specific, actionable suggestions for how the product's environmental impact could be further reduced and its sustainability enhanced.
