How does the impact water use category now have such an impact?

Question

Hello, 

When calculating with the EF 3.0 Method (adapted), the impact water use category has much more impact than than previously calculated with the EF (adapted) Method.

Is this change correct?

The problem is when normalization is done, the weights and percentages with the most relevant impact categories, the water use category occupies a place with great relevance, around 80/90%.

Are there any errors?

Thank you very much. 

Best regards,
