-    Based on the following environmental data, generate a comprehensive environmental score (0-100), aiming to reflect the product's commitment to sustainability.
-    
-    Product Data: {extracted_data}
-    Carbon Footprint: {carbon_footprint} kg CO2e
-    
-    **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.
-    
-    **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.
+    Based on the following environmental data, generate a comprehensive **environmental score (0-100)**. **Strive for higher scores where reasonable, reflecting a more optimistic assessment of sustainability efforts.** Please also **check the scores less stringently**, allowing for a broader range of evaluations.

+    **Product Data:** {extracted_data}
+    **Carbon Footprint:** {carbon_footprint} kg CO2e
+
+    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
+
+    **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.)
     
-    **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.
+    Provide:
+    * **Overall score (0-100, where 100 is most sustainable and 0 is least sustainable)**
+    * **Category breakdown** (scores for each factor listed above)
+    * **Improvement recommendations**
