Becoming carbon-neutral has become a key element of your CSR policy. A third of the UK’s largest businesses have set targets to reach Net Zero by 2050. Other businesses are taking more immediate actions, committing to Net Zero by the end of 2022. But how can saving water help your business achieve your Net-Zero target?
You may think that water itself doesn’t contribute to your carbon footprint. But there are greenhouse gases involved in the treatment of water as well as in pumping it to and from your premises. Add to this the carbon you produce when you heat the water or boil the kettle, and you can see how saving water in order to save emissions is inextricably linked.
One important factor to bear in mind is that wastewater produces more C02e (carbon dioxide equivalent) than your incoming water supply. Getting water to your taps creates 0.149 kg of CO2e per cubic metre. However, disposal of wastewater is nearly double this amount, creating 0.272kg of CO2e in each cubic metre.
Therefore, businesses that take steps to reduce their wastewater will get closer to achieving their Net Zero target.
Water from sinks, showers, dishwashers and washing machines, as well as collected rainwater, is known as grey water. Grey water can be diverted from being poured down the drain and used for other purposes, such as flushing toilets, watering grounds, and washing vehicles, paths, roads and yards.
By reusing grey water, you will not only significantly reduce the volume of wastewater you dispose of, you will also reduce the volume of clean water you need. The less water entering and leaving your premises, the lower your bills and the lighter your carbon footprint.
Even if your business hasn’t set a Net Zero target yet, there are plenty of ways you can reduce your water use in order to reduce your overall CO2e. The smallest and simplest changes of behaviour, for example, can go a long way.
Taking measures to save as much water as possible makes good business sense. If the only reason is to save money, then that is, of course, good for your business - but you’ll also be contributing to water conservation and reducing your carbon footprint at the same time, which is great for the environment.
