A comprehensive plan to reduce your carbon footprint in all areas of life: housing, food, travel, consumption, waste, leisure and finances. Each suggestion is based on recommendations experts and environmental organizations. New tips and important notes on Slovak/European conditions have also been added. Below you will find your personal carbon footprint reduction plan:
🏠 Housing
Reducing energy consumption
- Set the thermostat to 19–21 °C in winter a 25–27 °C in summer.
- Reduce the water heater temperature to 49°C (120°F), which can save up to 5–10 % energy without losing comfort when showering.
- Turn off electronics completely, not just to standby mode – so-called "energy vampires" can create up to 5 % of your consumption.
- Regular servicing of boilers and air conditioners improves their efficiency.
Better insulation
- Insulating the roof and walls and replacing leaky windows (triple-glazed) can reduce heating costs by up to 20–30 %.
- Seal gaps around doors and windows with self-adhesive tape.
Renewable resources
- Installing solar panels can cover 35–100 % annual consumption (in Slovakia rather an average value).
- If you live in an apartment, find out about opportunities to participate in community energy projects.
Energy-efficient appliances and water
- Replace old appliances (refrigerators, washing machines, ovens) with class A+++ (or the highest available) and use LED bulbs - save money 20–50 % energy.
- Buy an energy-saving shower head and a faucet aerator to save hot water.
- Saving water (taking short showers, fixing dripping taps) also saves energy for heating it.
Summary of key values for the Housing category
In this section, we break down residential CO₂ emissions into five main components: electricity, heating (space and hot water), lighting and appliances a other (cooking, cooling), for each of which we will give the typical annual consumption per Slovak household and convert it into kilograms of CO₂ equivalent. The result is an estimate 2 – 3 tons of CO₂e per year for an average 2.5-person household.
⚡ Electricity
- Consumption per person: 4,860 kWh/year
- Household consumption (2.5 people): 4,860 × 2.5 ≈ 12,150 kWh/year
- Emission factor (SR, 2024): 93 g CO₂e/kWh
- Annual emissions: 12,150 kWh × 0.093 kgCO₂e/kWh ≈ 1,130 kg CO₂e
🔥 Heating and hot water
Space heating
- Share in final household consumption (EU-27): 78,4 %
- Average annual energy consumption per household (EU-27): 15 MWh/year (space heating + TV + cooking + appliances)
- Estimated heating consumption: 15 × 0.784 ≈ 11.8 MWh/year
- Emission factor natural gas: 200 g CO₂e/kWh (typical EU)
- Emissions: 11,800 kWh × 0.20 kgCO₂e/kWh ≈ 2,360 kg CO₂e
Heat pumps and renewables
When using heat pumps (COP = 3), heating emissions are reduced by a third:
- Emissions: 2,360 kg ÷ 3 ≈ 787 kg CO₂e
💡 Lighting and appliances
- Share in final household consumption: 6.3 % (cooking 6.3 %), plus appliances and lighting ≈ 5 %
- Consumption estimate: (15 MWh × (6.3 % + 5 %)) ≈ 1.64 MWh/year
- Emission factor (electricity): 93 gCO₂e/kWh
- Emissions: 1,640 kWh × 0.093 kgCO₂e/kWh ≈ 153 kg CO₂e
🍳 Other (cooking, cooling, other)
- Cooking: 6.3 % of final consumption ≈ 0.945 MWh/year
- Emission factor natural gas/electricity (mix 50:50): 100 g + 93 g = 193 gCO₂e/kWh ÷ 2 ≈ 96.5 gCO₂e/kWh
- Cooking emissions: 945 kWh × 0.0965 kgCO₂e/kWh ≈ 91 kg CO₂e
- Cooling and others (0.6 % + 0.9 % = 1.5 %): 15 MWh × 1.5 % = 0.225 MWh/year
- Emissions: 225 kWh × 0.093 kgCO₂e/kWh ≈ 21 kg CO₂e
📊 Total household emissions estimate
| Component | Consumption (kWh/year) | Factor (kg CO₂e/kWh) | Emissions (kg CO₂e/year) |
|---|---|---|---|
| Electricity | 12 150 | 0,093 | 1 130 |
| Heating (gas) | 11 800 | 0,20 | 2 360 |
| Lighting & electrical appliances | 1 640 | 0,093 | 153 |
| Cooking | 945 | 0,0965 | 91 |
| Cooling & other | 225 | 0,093 | 21 |
| Total | 26 760 | 3,755 kg CO₂e |
Note: when using a heat pump (COP = 3), heating emissions drop to 787 kg, for a total of ~2,182 kg CO₂e/year.
🔧 Recommended measures with impacts
- Switching to a heat pump: reduction in heating emissions from 2,360 → 787 kg CO₂e (–1,573 kg).
- Installation of solar panels: covering 50 % of electricity consumption (6,075 kWh) will save ~565 kg CO₂e.
- Better insulation: reducing heating demand by 30 % (3,540 kWh) means saving ~708 kg CO₂e.
- Energy-saving LEDs and appliances: 50 % reduction in lighting and appliance consumption (820 kWh) will save ~76 kg CO₂e.
By implementing these four steps, a household can reduce its residential footprint by ~3,000 kg CO₂e annually, which represents up to 80 % current emissions from housing.
🥗 Catering
Plant-based and sustainable diet
- Limit red meat and dairy products. Substituting plant-based alternatives for beef will reduce emissions. 30–70 % per serving.
- Implement at least one “meatless day” per week (Meatless Friday).
- Drink tap water – the carbon footprint of bottled water is 500–1000× higher.
Local and seasonal foods
- Buy local and seasonal food, shortening the supply chain and minimizing emissions.
Reducing food waste
- Plan your shopping and portions, store food properly.
- Food waste produces methane when it decomposes - by reducing waste you can save up to 10 % CO₂ household.
Composting of biowaste
- Compost at home or use community collection. You will reduce the amount of mixed waste and the creation of greenhouse gases in the landfill.
- Compost also improves the quality of the soil in the garden or in flower pots.
Summary of key values for the Dining category
Meals are approximately 25–30 % of total greenhouse gas emissions associated with individual lifestyle, with animal products, especially red meat and dairy products, accounting for the largest share. For Slovakia (the average diet emits approx. 2 t CO₂e per year per person) switching to a more plant-based diet can reduce carbon footprint by up to 0.5–1 tCO₂e per year. In the following sections, we analyze emissions by food category, provide values per kilogram and per regular serving, and illustrate the potential savings from changes in food choices.
🥩 Animal products
Red meat
- Beef: average footprint 60 kg CO₂e/kg.
- Mutton/goat: around 186 kg CO₂e/kg (highest among meats)
- A 200 g portion of beef steak: 0.2 kg×60 kg = 12 kg CO₂e.
White meat and fish
- Chicken meat: 2.6 kg CO₂e/kg according to CarbonCloud, or 6–7 kg CO₂e/kg according to other studies.
- A serving of 150 g grilled chicken: 0.15kg×2.6kg ≈ 0.39 kg CO₂e.
- Salmon: ~9.1 kg CO₂e/kg (fish have a wider range of 1–10 kg.
- A serving of 150 g salmon: 0.15kg×9.1kg ≈ 1.36 kg CO₂e.
Dairy products and eggs
- Milk: approximately 2.4 kg CO₂e/l.
- Cheese (danbo, 45 % tt): 7.7 kg CO₂e/kg.
- Butter: 3.9 kg CO₂e/kg.

- A serving of 30 g of cheese: 0.03kg×7.7kg ≈ 0.23 kg CO₂e.
🌱 Plant alternatives
Legumes and cereals
- Tofu: 0.08 kg CO₂e per 100 g ≈ 0.8 kg CO₂e/kg.
- Beans/lentils: ~0.9 kg CO₂e/kg (based on comparison with rice).
- Rice: 0.16 kg CO₂e per 100 g ≈ 1.6 kg CO₂e/kg.
- A serving of 200 g tofu: 0.2kg×0.8kg = 0.16 kg CO₂e.
Fruits and vegetables
- Apple: 0.06 kg CO₂e/pc (150 g).
- Potatoes: ~0.1 kg CO₂e/kg (many root vegetables are below 0.5 kg/kg).
- Vegetable salad (200 g): at 0.1 kg/kg = 0.2 kg×0.1 kg = 0.02 kg CO₂e.
Nuts and seeds
- Mixed nuts: 0.05 kg CO₂e per 100 g ≈ 0.5 kg CO₂e/kg.
- A serving of 30 g of nuts: 0.03 kg×0.5 kg = 0.015 kg CO₂e.
🍽️ Typical diet and annual emissions
| Food | Quantity | Emissions (kg CO₂e) |
|---|---|---|
| Morning coffee with milk | 200 ml milk | 0.2×2.4 = 0.48 |
| Omelette (2 eggs) | 100 g eggs | 0,53 |
| Lunch – beef steak | 200 g | 12 |
| Side dish (rice 150 g) | 0.15 kg | 0.15×1.6 = 0.24 |
| Snack – apple | 1 pc (150g) | 0,06 |
| Dinner – tofu stir-fry | 200g tofu | 0,16 |
| Daily amount | 13.47 kg | |
| Annually (365 days) | 4,920 kg CO₂e |
If you replace beef steak tofu stir-fry once a week, you'll save 12 kg × 52 = 624 kg CO₂e per year, so you will reduce food emissions from 4.92 → 4.296 tons CO₂e/year.
📉 Impact of changes in selection
- Red meat → plant-based alternative
- Savings: 12 kg CO₂e per serving.
- Milk → plant-based drinks (e.g. soy 0.9 kg CO₂e/l)
- Savings: 2.4 – 0.9 = 1.5 kg CO₂e per liter.
- Eggs → chickpea omelets (0.08 kg/100 g)
- Savings: 0.53 – 0.16 = 0.37 kg CO₂e per portion.
By implementing these three changes (1 steak, 1 liter of milk, 1 portion of eggs per week) you can save up to (624 + 78 + 19) ≈ 721 kg CO₂e annually.
🔑 Summary
- Animal products dominate the dietary footprint: beef up to 60 kg CO₂e/kg, mutton 186 kg/kg.
- White meat a fish they have a lower footprint (2–10 kg CO₂e/kg).
- Plant-based foods are 10–50x better (0.05–1.7 kg CO₂e/kg).
- Change once a week from red meat to a plant-based alternative will save >600 kg CO₂e annually.
Transition to more plant-based diet is one of the most effective ways to reduce your personal carbon footprint.
🚲 Travel and mobility
Short walks or bike rides
- You can cover distances up to 5 km on foot or by bike - a car emits approximately 200g CO₂/km.
Public transport and car sharing
- Prefer public transport, train or car-sharing. Public transport has up to 40–70 % lower emissions per person.
- Carpool with colleagues or family.
Switching to an electric vehicle
- Consider an electric car or plug-in hybrid – they produce up to 70 % lower emissions than regular cars.
- Monitor the carbon mix of electricity in the country – electric cars are cleanest where there is a lot of nuclear, hydro or wind.
Less flying

- When on vacation, prefer the train or bus over the plane.
Summary of key values for the Travel and Mobility category
To give you a clear picture of the emissions associated with your mobility, we divide “Travel and Mobility” into five main sections: individual transport (car, electric vehicle), public transport (bus, train), short distances (walking, cycling), air transport and shared mobility (car-pooling, car-sharing). We quantify each category in detail in grams of CO₂ per kilometer and illustrate this with typical annual or monthly distances. Overall, you will get concrete numbers based on which you can monitor your emissions and reduce them in a targeted manner.
🚗 Individual car transport
