Facts and tips to help you to reduce your carbon footprint

  • Go To


When purchasing a new appliance it is vital to check the energy rating label.

An 'A' rated appliance will use about 55% of the electricity of a similarly sized appliance with a 'D' rating. For example, by purchasing an 'A' rated fridge instead of a 'C' rated one, each household could save €14 per annum or collectively €18m nationally, with CO2 savings of over 85,000 tonnes annually.


CFL bulbs use 80% less electricity and last 15 times longer than an ordinary bulb.


Did you know that cars are responsible for approximately 12% of total EU emissions of Carbon Dioxide (CO2)?

You can make significant savings to your carbon footprint by choosing to leave the car at home, where possible, and riding a bike or walking to work.

And on winter mornings, it may be tempting to turn on the engine to heat the car. But you should try to avoid this. Not only does this waste fuel but it leads to rapid engine wear.


With ActiveWater™ technology, Bosch dishwashers use only 6 litres of water on the Economy 50ºC programme to wash 13 place settings. If you washed the same load by hand, you would use approximately 49 litres. This means you could save over 12,000 litres of water a year!

Electric ovens

When cooking, try not to open the door of the oven. You can lose as much as 20% of the heat every time you do.


Your fridge is on for 24 hours a day so it is natural to want it to be as energy efficient as possible. Bosch offer eight super-efficient models with an A++ rating that use up to 40% less energy than an equivalent A rated model.


It is estimated that the average home loses 20% of its heat through the windows. By upgrading your windows from single to double or triple glazing you can keep out the draught and also reduce your heating bills by dramatically minimising heat loss through the glass.


Turning the thermostat down by just 1°C can cut as much as 10% off your heating bills.

You can also save on running costs by heating your home for an hour less each day.

Induction hobs

When cooking on a hob or a stove, always cover your pots and pans with lids. This will help you to cook the food faster. Better still use a tiered steamer, it can enable you to cook your entire meal on one hob ring.


The short term expenses of upgrading your home and making it more energy efficient quickly become justifiable when you consider the long-term savings that can be made.

For example, by insulating your attic well, you could save up to 20% on your home heating bill - as much as €200 per year.


Did you know that overfilling the kettle can be bad for the environment? Recent studies have found that 67% of people use more water than needed when filling a kettle. When making tea, be sure to only boil the amount of water you need. This will save both energy and water.


Just because you want to cut back on your energy conservation shouldn't mean that you have to compromise on the quality of your washing machine.

With a Bosch washing machine, which uses VarioPerfect™ technology, you can have laundry that is 100% clean using 66% less energy.


Believe it or not, a microwave is one of the most energy efficient appliances in your kitchen. In fact some microwaves use 30% less energy than conventional ovens.


Typically, the "as new" efficiency of an oil or gas boiler over 15 years old would have been less than 80%. It's present efficiency today, due to wear and tear is unlikely to be greater than 70%.

The current range of boilers available today will have efficiencies greater than 90%. This represents an operational improvement in efficiency of up to 20 percentage points. Increasing the operational efficiency of your boiler by this amount represents an actual fuel saving of more than 25%. In other words, by replacing an older, low efficiency boiler with a new, high efficiency boiler, you can cut your fuel bills by a quarter.

One million

In Ireland, over one million tonnes of food waste is generated annually. This waste produces methane in landfills as well as carbon emissions from transporting the wasted food. By only buying what you will consume, you can make a big difference to the environment.


Do you care about the environment? Purchasing the most energy efficient appliance will save you money on your energy bills and be less harmful to the environment in the long run. Also, the more we choose energy efficient products, the more manufacturers will have to make energy efficient appliances - this gives us power as consumers to make changes happen.

Quick shower

Simply put it's far more water efficient to have a quick shower than to have a bath.

The average bath uses 80 litres of water compared to an average seven-minute shower which uses 49 litres.


When you're leaving a room make sure you turn the light switch off. A bright room with no one in it is a waste of electricity!


By leaving certain appliances on standby you could be using as much as 10% to 60% of the electricity that would be used by the device if it was switched on.

Why not just plug the device out? You'll undoubtably make savings to both your electricity usage and your energy bills.


Don't let the tap run! Brushing your teeth with the tap running can use up to six litres of water per minute.

Fitting a solar hot water heating system is an excellent way of making your house more energy efficient as it reduces the amount of fuel used to heat hot water. Did you know that you can get grants from the SEAI for a number of improvements such as introducing solar heating into the home?


Bosch offer vacuum cleaners which use as much as 50% less energy than alternative options on the market.

Water waste

By being leak-free you can save huge amounts of water. Check for running overflows and fix any dripping taps, cisterns or pipes. It is also important to know how to turn off your water supply. This could save thousands of litres of water and can prevent damage to your home in the event of a pipe burst.


90% of the energy consumption of washing machines goes on heating the water. Wash clothes whenever possible in cold or cool water and watch your energy savings multiply!

Your environment

Wasting energy isn't good for the environment. Most of the energy sources we depend on, like coal and natural gas, can't be replaced. Conserving energy around the home can have a positive impact on the environment.


Set your heating to go off before you go to bed, the radiators will continue to heat your home for some time.
