How to reduce your carbon footprint: 9 tips to achieve it

By 20 de December de 2024July 21st, 2025No Comments
[The carbon footprint, one of the indicators that teaches us that our actions do impact the environment. Whether you’re at home or in a business, our daily activities emit greenhouse gases, accelerating climate change. The good news is that this can be changed, and here we show you how to reduce the carbon footprint with practical and effective actions, both at home and at work.

What is the carbon footprint?

The carbon footprint measures the exact amount of greenhouse gases, such as carbon dioxide and methane, emitted directly or indirectly by our activities. These contribute to global warming, causing certain phenomena like heatwaves, storms, or rising sea levels.

Although transport and industry are responsible for a large part of these emissions, households also generate 23% of the total emissions in Spain, according to INE data from three years ago. This is why every small action counts. Additionally, according to INE, last year, emissions decreased by 5.5% compared to 2022, with 22.9% coming from households. However, the figure remains concerning, reaching 287.7 million tonnes of greenhouse gases.

Why is it important to reduce the carbon footprint?

Because it has numerous benefits for everyone. The most important things we can highlight about reducing the carbon footprint are that, together, we can:

  1. Mitigate climate change by slowing the rise in global temperatures.
  2. Protect biodiversity by preserving habitats for plants and animals in much better conditions.
  3. Save resources and money by being more efficient and reducing costs in electricity, transport, and materials.
  4. Improve quality of life. If pollution decreases, so do health issues related to respiratory and cardiovascular diseases.

How to reduce the carbon footprint at home

Let’s start with small changes at home and in daily life. The best tips to begin reducing your carbon footprint at home are:

1. Switch to renewable energy

First and foremost, it is crucial to install solar panels at home to significantly reduce CO2 emissions. This provides a renewable and clean energy source, lowering your greenhouse gas emissions. Moreover, there are grants available to facilitate this transition.

2. Reduce, reuse, recycle

To minimise all types of waste, which are one of the main sources of emissions (especially in landfills), you should:

  1. Separate your waste correctly: glass, paper, plastics, organic waste.
  2. Reuse containers and materials whenever possible.
  3. Repair your appliances instead of discarding and replacing them with new ones.
  4. Plan your purchases well to avoid waste. This way, you will only buy what you need, reducing waste and avoiding excessive resource consumption in production.

3. Optimise electricity consumption

Electricity usage has a significant impact on the carbon footprint, and if you don’t know how to reduce your carbon footprint at home, small adjustments can make a big difference:

  1. Turn off devices on standby mode, such as TVs or chargers.
  2. Replace traditional bulbs with LED.
  3. Wash clothes with cold water and air-dry them.
  4. Ensure your doors and windows are insulated to prevent heat loss in winter or cool air loss in summer.

4. Use natural light

This is related to the previous point, as it’s another way to optimise consumption, but it’s crucial to understand the importance of reducing energy use. Organise your home to let in as much natural light as possible. To do this:

  1. Paint walls in light colours that reflect light better.
  2. Keep windows clean and free of furniture to let in more light.

5. Buy local and seasonal products

Imported food travels long distances before reaching your table, generating unnecessary emissions. The closer the product, the better. Combining this with buying seasonal products ensures:

  1. Less transport.
  2. Less plastic packaging.
  3. They are much fresher and of better quality.

Additionally, consuming less meat, especially red meat, also has an impact, as intensive livestock farming is one of the main sources of greenhouse gases.

6. Use more sustainable transport

Cars produce an enormous amount of tonnes of CO2 annually due to fossil fuel combustion. So yes, petrol (or diesel) cars are highly polluting, and it’s essential to know how to reduce the carbon footprint here as well.

The most helpful and straightforward advice is to use public transport, which is very efficient and much more sustainable. You can also walk or cycle for shorter journeys.

On the other hand, if you must use a car—for example, if you work in the suburbs and there’s no company bus—the best option is to carpool with a colleague.

7. Control water usage

Although it might seem like an inexhaustible resource at home, clean water requires processes that consume energy and generate significant emissions. Simple actions like these help a lot:

  • Spend less time in the shower.
  • Use aerators on taps to use less water.
  • If it rains a lot in your area, reuse that water for watering plants.
  • Do not use the washing machine until it’s full.
  • Turn off the tap while soaping dishes or brushing your teeth.

8. Be mindful of heating and air conditioning

Home climate control can account for up to 50% of energy consumption. If you want to optimise it properly and reduce your carbon footprint at home, follow these tips:

  1. Set the thermostat to an efficient temperature: 21 °C in winter and 24-26 °C in summer.
  2. Use curtains and blinds to better insulate your home from heat and cold.
  3. Check and improve the insulation of doors and windows to prevent energy leaks.

9. Reduce plastics

Plastic is one of the most impactful materials due to its slow decomposition, so avoiding it is essential. To achieve this:

  1. Replace disposable water bottles with reusable glass bottles, or if not, steel ones.
  2. Buy food in bulk.
  3. Use reusable containers to store food instead of plastic wrap or single-use bags.
  4. Use a large tote bag or trolley for shopping instead of buying plastic bags at the supermarket.

How to reduce the carbon footprint in a company?

As mentioned, businesses have a significant responsibility in the fight against climate change, so it’s crucial they also know how to reduce their carbon footprint. Here are some suggested steps:

  1. Implement energy efficiency audits for companies. Knowing the company’s energy consumption is the first step to identifying areas for improvement. A professional audit can help optimise processes. For example, you can start by:
    1. Replacing lighting with LED technology.
    2. Installing solar panels for businesses.
    3. Monitoring consumption to detect and correct peaks.
  2. Promote sustainable mobility.
    1. Consider contracting a company bus.
    2. If feasible for your type of work, implement remote workdays to reduce unnecessary commuting.
    3. Install chargers for electric vehicles in your parking lot.
  3. Digitalise processes and reduce paper usage. If you haven’t already, it’s important to digitalise your company, from documents to electronic signatures. This reduces paper printing considerably. Of course, you can also use recycled paper and recycle ink cartridges.
  4. Optimise energy consumption in offices.
    1. Set air conditioning and heating to moderate temperatures, as mentioned earlier: 21 °C in winter and 24-26 °C in summer.
    2. Turn off lights and equipment at the end of the workday.
    3. Use motion sensors in passage areas.
  5. Collaborate with suppliers who, like you, adopt practices to reduce the carbon footprint.
    1. Prioritise recycled materials or products with eco-certifications.
    2. Purchase locally to reduce transport emissions.
    3. Partner with companies that use renewable energy.

FAQs about reducing the carbon footprint

What individual action contributes most to reducing the carbon footprint?

When it comes to individual actions, the best way to reduce your carbon footprint is not driving. Walking or cycling to places is ideal. Not only will fewer greenhouse gases be emitted, but it’s also beneficial for your health and fitness. Of course, for longer journeys, use buses or trains.

What activities generate the most carbon footprint?

It depends on whether we focus on individual actions or companies. The activities that generate the most carbon footprint individually are transport, energy consumption, and personal consumption habits.
On the other hand, for companies, the activities generating the most carbon footprint include agriculture, livestock, forestry, and fishing (as a combined sector) with 947,691.3 tons of methane. Regarding CO2, the manufacturing industry accounts for 59,928.0 thousand tons.]
