Techniques for a sustainable lifestyle. Calculate your CO2 footprint

Print Resource
  • Resource Information

Abstract

Researchers recommend that an individual’s annual emissions of carbon dioxide equivalents must be 1 tonnes by 2050 if the goal of limiting the global average temperature increase to less than 2 degrees is to be achieved. Carbon dioxide equivalents are a measure of greenhouse gas emissions that take into account that different such gases have different abilities to contribute to global warming. In 2017, the figure was 6.7 tonnes per person within the EU, 13.5 tonnes for Canada, 16.3 tonnes for Australia and 16, 4 tons for USA.

We all have to contribute. Greta Thunberg speaks to us:

This exercise can start as a group exercise and a kind of brainstorming and can then be performed individually. It is a conscious exercise about the things we invite in our homes and about the conscious choices we can make to have a sustainable lifestyle. The exercise should be seen as a kind of brain storming and ideas can be gathered. Several ideas will be presented in the exercise and for participants to practice in their own life for a month. Are they relevant for them or not?

Learning Outcomes

  • Explain how the CO2 Footprint is used
  • Explain the concept of sustainability
  • Identify techniques for a sustainable lifestyle
  • Create new techniques for a sustainable lifestyle
  • Develop behavior change individually for an eco friendly lifestyle
  • Motivate behavior change for a sustainable lifestyle.
  • Discuss possible changes
  • Test the proposed changes for a month
  • Evaluate the pros and cons
  • Conclude how to go ahead

Other Instructions

Read through some of these ideas and discuss if they can be relevant in your life: Boil water If you are going to boil water, it is best to use a kettle to quickly get up in the high temperatures. With a kettle, the water boils up faster than on a hob, which takes less energy. Here’s how: If you boil water on a regular stove, it takes about ten minutes and it draws over 200 WH (watt-hours). If, on the other hand, you boil the same amount of water in a kettle, it takes about four minutes and draws below 140 Wh. You save energy, money and time.  Mobile and TV The mobile charger draws energy even when it is not charging the mobile. There are also reports that it can overheat and start to burn. So be in the habit of unplugging the charger when the phone is not charging. The TV also draws energy in standby mode. The larger a TV screen is, the more energy it draws when it is on. Even a separate digital TV box can draw as much electricity as a smaller TV. A convenient thing is to switch off several devices at the same time with the help of a branch contact with a switch. Fridge and freezer A fridge and freezer consumes about 25 percent of all energy consumed in the home. Save energy by keeping the right temperatures, the fridge should be +5 degrees and the freezer -18. Each extra degree colder in the freezer increases energy use by 5 percent. And do not forget to freeze the freezer regularly!! Twice a year is usually enough. An ice-covered freezer consumes significantly more energy than one that is defrosted. Allow the food to cool and cover it well before setting it in the fridge or freezer. If hot food is set in the fridge, it takes unnecessary energy to cool it down. Also make sure to keep it clean behind your fridge and freezer. Regularly dusting behind the refrigerator counteracts the cooling unit being forced to work harder. Dishwasher and washing machine Be sure to fill the machines before starting them. This applies to both the dishwasher and the washing machine. Or set the machine to half wash / dish if that function is available. Do not overdose and remember to choose eco-labeled detergents. Rinse aid is not needed to clean the laundry and contains dangerous chemicals that end up in nature, so you can manage but it is good for the environment. Sort at source, reuse, and buy second hand There are lots of ways to avoid producing new – which wastes a lot of energy. Sort the source as much as possible, buy second-hand clothes and keep track of used pages for furniture. Or why not update the furniture (change – repaint – sell – give away) instead of getting rid of them! If you buy second hand, you save up to 97 percent of the energy spent on making new clothes. Producing a lot of new feels very unnecessary and energy-intensive when we have produced so much already, right! Chose renewable energy Today it is easy to change electricity contracts, if you want to do so. Today, most large – and small – electricity companies offer the alternative of getting energy from renewable energy, such as hydropower, wind power, solar energy and bioenergy. (In Sweden, we can pat ourselves on the back when it comes to this. A goal for climate and energy policy by 2020 is that at least 50 percent of energy use should be covered by renewable energy. Already in 2012, the goal was exceeded and in 2015 54 percent of the energy used in Sweden from renewable energy sources. Today, most large – and small – electricity companies offer the alternative of getting energy from renewable energy, such as hydropower, wind power, solar energy and bioenergy.) It can be done if there is a will. Save on heating your home Seal draft windows and exterior doors with sealing strips to easily reduce the amount of Cold air that enters the home. You can also review insulation on the attic, for example. About 15 percent of the heat disappears through the roof. Avoid covering the elements. With furniture or large curtains. Lower the heat in rooms that are rarely used, such as The hall. A lower temperature in the bedroom also often contributes to better sleep. Reduce the amount of hot water Reduce the beam of showers and faucets can reduce water use up to 40 percent. You will not notice any major difference except on the electricity bill. Also remember to reduce your shower time. If you take a faster shower in 5 minutes instead of showering for 15 minutes, you save precious kroner with each shower. Invest in eco-friendly technology Want to go further than simply turning it off? Make sure that the tech you have got is as energy-efficient as possible. This way, you’re using much less energy for the time that the product is on, saving money, and reducing your energy output. Eat less meat Being careful with what you’re consuming is at the heart of being more eco-friendly, and cutting down on the amount of meat you eat can have a huge impact. Not having red meat – even if it’s just for two or three days a week – can have quite a significant impact on reducing your carbon footprint. Don’t waste food Waste not, want not. Did you know that 7.3 million tons of food is wasted in the UK every year? This isn’t just a huge waste of food and money, it adds to the amount of CO2 being created in landfills. Compost If you have let your food go that little bit too far past it’s ‘best by’ then you need to be sure to compost it rather than putting it in the bin. Not only will this help create a natural fertilizer and keep your garden green, it’ll also reduce the amount of waste going to landfill – and as it won’t break down an aerobically, there will not be a build-up of methane gas. Recycle everything Chances are that if you’re thinking about taking on a more eco-friendly lifestyle then you’ll already be recycling. But could you improve your recycling-ability (now a word)? You can recycle almost everything, from batteries to paper to cars. Before you throw it away, take a minute to find out if you could recycle it instead. Try to cut out plastic Plastic seems to have found its way into every single aspect of our lives. However, giving it up isn’t as difficult as you might think – bring a canvas bag with you when you go shopping, buy your fruit and vegetables loose and stop buying bottled water. Use LED light bulbs Not only do LED light bulbs last longer than conventional bulbs, they’re far more efficient too! This means that you’ll be using less power and having to replace your light bulbs less frequently – everyone’s a winner. What’s more, they’re available in a range of brightness and designs so you can really tailor the lighting to your needs or to suit the room. Insulate your home Homes that aren’t well insulated are much harder to keep warm when it’s cold, and cool when the weather is hot. Insulating your home is one of the best eco-friendly tips for your home that we can offer you. Have your food shop delivered Home delivery is like the public transport of groceries. Instead of having 20 odd cars make their way to the supermarket – one van drives around delivering to everyone in the area. ( became very popular in Corona time)Additionally, it means you’re less likely to impulse buy which can help to reduce any waste food. Fix it, don’t throw it Repairing or fixing something is more environmentally friendly than simply throwing things away, although the latter may seem easier and cheaper sometimes. The internet gives you access to the tools and information you need to fix practically anything, and if you still can’t fix it then why not try and turn it into something else? Use eco-friendly cleaning products A lot of cleaning products have a lot of harmful chemicals in them that aren’t environmentally friendly to create or dispose of. In fact, repeated exposure to these cleaning products can affect your health as well as the environment. Green cleaning products use more natural and organic methods of cleaning which are far less harmful. Here are some great tips on our partners at the National Trust: Public transport If you can make the journey by foot, bike or public transport, then do it. Driving, unless you’re in an electric vehicle, isn’t very eco-friendly and can really add to your carbon footprint. When you do have to drive, make sure that you get the most out of your vehicle by keeping the speed down, ensuring tires are properly inflated and that the engine is running smoothly. Buy local From clothes to food, the closer to home these products are made and bought, the less carbon is created with their transportation. Not only that, but you’ll be supporting the local economy which means that in time you’ll likely have even more local items to choose from. Grow your own Growing your own vegetables isn’t just a good way to save money, it’s also a great way to cut down your carbon footprint and be eco-friendly. Don’t have any outside space? Windowsill boxes are a great way to brighten up your view, filter the air coming into your home and offer plenty of space for herbs and small vegetable patches. Plant some trees Ecological sustainability is very important when it comes to eco-friendly living. Without a stable ecosystem, things start to fall apart. Making sure that we’re planting more native trees to replace those that have been felled to make room for developments is something that more people and businesses need to do to protect the environment and improve air quality. Choose your personal care wisely When it comes to personal hygiene there are several things you need to be careful to avoid for a truly Eco-friendly lifestyle. The most damaging of these is micro beads, which are small bits of solid plastic which aren’t biodegradable and make their way into watercourses and ultimately end up damaging the environment by entering the food chain. Make sure that your body wash, toothpaste, face scrub and other products do not contain these beads. In addition to this, avoiding chemicals and opting for natural cleaning products.
