How do the Citola Widget's Carbon Calculators work?

The Citola Widget's Carbon Calculators reflect the best international practices and use the latest climate change and emissions information from the Greenhouse Gas Protocol the International Panel on Climate Change, the UK Department of Environment Food and Rural Affairs, the UK Vehicle Type Approval authority and the Australian Greenhouse Office.

How does the Citola Widget's Tree Calculator work?

Trees take in CO2 from the atmosphere and store it in the biomass of their root systems, leaves and trunks. This carbon sequestration is an important part of mitigating climate change.

The Citola Widget's Tree Calculator enables you to offset your carbon footprint by investing directly into projects that plant trees.

How does the Citola Widget's House Carbon Calculator work?

Every time you switch on a light or an appliance you are consuming energy whose production emits carbon pollution and contributes to global warming and climate change.

The Citola Widget's House Carbon Calculator enables you to offset your household's carbon footprint using the ‘Energy Bill’ method by manually selecting your energy consumption information or the ‘House Type’ calculator which is based on first-world averages.

  • Unit/Studio = 10 kWh/Day
  • Small House (1 bedroom) = 15 kWh/Day
  • Medium House (2 bedroom) = 20 kWh/Day
  • Medium House (3 bedroom) = 25 kWh/Day
  • Large House (4 Bedroom) = 30 kWh/Day
  • Large House (4+ Bedroom) = 35 kWh/Day

How does the Citola Widget's Car Carbon Calculator work?

Every time you use your car you are emitting CO2 into the atmosphere and contributing to climate change. 

The Citola Widget's Car Carbon Calculator enables you to offset this impact on the environment and uses dynamic information from the UK Vehicle Certification Agency database of vehicle emissions for each car make and model. If your model is not listed, or you would like to input manual fields, use our Car Data Calculator based on Fuel Type and Fuel Efficiency.  To find out your vehicle fuel economy consult the log book or the manufacturer or use the following assumptions:

Petrol

  • A typical small car may have a fuel economy of 36 mpg (7.8 l/100km)
  • A typical medium car may have a fuel economy of 30 mpg (9.4 l/100km)
  • A typical large car may have a fuel economy of 22 mpg (12.8 l/100km)

Diesel

  • A typical small diesel car may have a fuel economy of 47mpg (6 l/100km)
  • A typical large diesel car may have a fuel economy of 39 mpg (7.2 l/100km)

How does the Citola Widget's Flight Carbon Calculator work?

Air travel is emissions intensive and is one of the fastest growing sources of carbon pollution and causes of climate change.

The Citola Widget's Flight Calculator follows the best international practices and takes into account the variance in emissions for short, medium and long-haul flights (such as proportion of fuel used for takeoff, travel and landing), the curvature of the earth, radiative forcing and emissions activities. The Citola Widget's Flight Carbon Calculator allows you to offset any flight.

Radiative Forcing takes into account the contribution that other greenhouse gases (including NOx compounds, ozone, methane) have on climate change when emitted from the aircraft at high altitude directly into the atmosphere. The radiative forcing index, internationally agreed to be approximately 1.9, translates to an aircraft having almost double the harmful effect on the environment when traveling at high altitude compared to emitting the same amount of CO2 on the ground.

How does the Citola Widget's Commute Carbon Calculator work?

Using Public Transport is a great way to reduce your impact on the environment as it is a far more efficient use of energy (as the emissions are relatively constant for transporting a greater number of people). However, there is still a carbon footprint associated with your daily commute or trip.

The Citola Widget's Commute Carbon Calculator utilises the emissions profile of the specific transport mode you utilise, and allows you to offset these emissions.

How does the Citola Widget's Quick Carbon Calculator work?

The Citola Widget's Quick Calculator enables you to select how many tonnes of CO2 you would like to offset, the amount of money you have to invest into Carbon offsets or an 'offset' package equating to a particular activity, event or action.
