Many hotels, conference venues and restaurants offer tap water instead of bottled water for good environmental reasons.

Tests show that tap water tastes better, is more cost-effective, and less harmful to the environment than bottled water. It is clearly the best choice since bottled water uses 1,500 times more energy to produce than tap water.

• When possible, choose water from the tap instead of bottled water
• If you have a water bottle, refill with tap water
• If you drink bottled water, remember to recycle the bottle.

This advice only applies in countries like Denmark which has potable drinking water.
