Why is locally bottled water more sustainable?

Tapping and bottling your own water using a water cooler directly connected to the mains is way more sustainable than serving water bottled in factories far away.

We’re happy to elaborate below.

A glass bottle of water from the factory emits as much CO2 as a three kilometer car drive.

factory bottled water causes extra carbon emissions

Water bottling plants cause additional carbon emissions. A study commissioned by the Netherlands Consumer Association showed that for the bottling of one glass of spring water 450 gram CO2 is already emitted. That is equivalent to a car ride of about three kilometres! This is mainly due to the production of the glass, the process of bottling and the transport to and from the point of sale.

Reusing is better than recycling

Glass is made by melting sand, soda (sodium carbonate) and lime together. This is a very intensive production process and therefore costs a lot of energy. In the Dutch hospitality industry, small bottles usually come with a deposit, large bottles usually go to glass recycling. In both cases it is much more sustainable to reuse bottles locally, because no transport is needed and the process of melting is prevented. In addition, a bottle with a deposit is only reused for about 40 times compared to over a few hundred times with local bottling.


It is quite hard to express the exact amount of carbon dioxide saved by using a water cooler instead of serving bottled water. However, we can give a calculation example of the number of truck rides that are being saved. Our figures show that our ambassadors in hospitality serve an average of 400 bottles of water per month: about 225 large and 75 small bottles together.

This adds up to about four standard shipping containers per participant per month no longer transported. Carrying 12 containers per ride, every third location serving Made Blue Water takes one lorry off the road. Or else: Our current ambassador group keeps about 100 trucks off the street every month! 


However, much larger CO2 savings take place in developing countries where we are working on access to clean drinking water. By making drinking water readily available, carbon emissions are avoided as a result of preventing the usual boiling of polluted water. 

For example, IRC calculated that a ceramic water filter reduces 1,03 tons of CO2 per year per filter. Conservatively, with 10 users per filter and the UN figure that 1 person needs at least 20 litres of water per day, the filter is good for 73,000 litres per year.

This means that 1 million litres of clean drinking water provides a CO2 saving of 13.74 tons and 1,000 litres provides 13.74 kg of CO2 savings. We already realized more than 6 billion litres of clean drinking water… do the math!

Turning tap water into spring water

In short, by bottling water locally, both glassware and transport related emissions are prevented. This is not only better for our world, but also for your staff: bottled water no longer needs to be carried around, refrigerated or tossed!
