Non flash calculator | Energy Lab Calculator

The carbon calculator provides a simple guide to your household carbon footprint based upon key features of your home, your personal energy use profile, your use of green technologies and your transport profile.
A household carbon footprint is the quantity of CO2 emitted to the atmosphere as a result of household energy use, transportation and waste disposal in one year.

This version of the carbon calculator is based on evidence from household energy studies in Australia, Canada, China, France, Germany, Hong Kong, Netherlands, United Kingdom, United States, Singapore, and South Africa. It enables you to explore how changes to your home, the way you use energy and your transport choices can affect CO2 emissions.
Because the calculator does not ask you for specific data on how much fuel or electricity you consume, it is easy to use but is only intended as an approximate guide.

To use the calculator complete the questions within each of the four sections. As you select options within the calculator, the resulting CO2 emissions are displayed above. Please note that this calculator data is based on 2005 data.

What size is your carbon footprint?

The first step to lowering carbon emissions is to understand your carbon footprint. This tool helps you to estimate your household CO2 emissions and shows how different lifestyle choices, household features and new technologies affect the size of your footprint.

General Household Conditions

Efficient features such as compact fluorescent light bulbs and insulation can reduce household energy consumption and associated CO2 emissions. When purchasing new appliances look out for the Energy Star label in the USA or Grade A labels in Europe that indicate high efficiency. Features such as air conditioning or a heated swimming pool will increase your household energy consumption and CO2 emissions.

Household heating system:

Cavity wall and loft insulation

Cavity wall insulation and loft insulation reduce heat loss from the building,reducing the amount of fuel you need to keep warm.

Draft Proofing

Draft proofing around external doors and windows reduces losses of heat from the building.

Double Glazing

Double glazed windows trap a layer of air between the two panes,creating an insulator that reduces heat losses.

Energy efficient light bulbs

Energy efficient light bulbs can produce the same amount of light with 80% less energy input than conventional tungsten bulbs.

Efficient appliances (A-rated/energy star)

Additional air conditioning

Air conditioning units used in addition to any installed system.

Personal Energy Use Profile

By using energy wisely in your home you can make significant reductions to CO2 emissions. See the reduction that can be made to your household footprint by selecting some of the options opposite.

I switch off lights when not in room

I don't leave equipment on standby

I mainly take showers rather than baths

I adjust temperature controls to avoid overheating

I recycle at least 30% of my household waste

New & renewable technologies

New and renewable technologies can save money, reduce energy and reduce CO2. Investigate what reductions you could make by installing some of the technologies listed. You may need specialist advice to assess which technologies are suitable for your home.

Condensing Boiler

Condensing boilers are applicable for houses with water-based heating systems. They extract an additional 10 to 20% of the heat from the flue gases compared to conventional boilers.

Ground source heat pump

Ground source heat pumps are under-floor heating systems that can be used to replace traditional boilers or furnaces used for heating. Ground source heat pumps use temperature differences between the ground adjacent to the building and the air inside to help warm the building in winter and cool it in summer.
