Climate Impact Calculator

Estimating your contribution to climate change

Introduction

This calculator helps you to estimate the climate impact of your own life.

It is divided into seven categories: transport; energy; food; waste; house building; other goods and services; and public services. At the end you'll be able to see where your life has the biggest impact, and be pointed towards ways you can try and reduce this.

It's pretty easy to fill in - you don't need access to precise information. It may not quite fit your lifestyle so be creative and make guesses - but do be honest with yourself!

Though you can fill the calculator in on your own, you might find it more enjoyable to do it with other people. How about getting together a group in your meeting to go through calculators, talk about what you find and work together on reducing your impacts?

About

Calculations are made in kg of CO2-equivalent gases per year. Some activities emit gases (e.g. methane, nitrous oxide) that have a much higher impact per kg than CO2, and this is taken into account in the calculations. As far as possible the calculations account for the total impact of activities in each category, which may mean that the numbers differ from other calculators. For example, the calculations for food take into account transport and sales of food, as well as agriculture and processing. A few notes are given under each section.

This calculator has been produced by Britain Yearly Meeting and Living Witness based on calculations by Living Witness. See www.quaker.org.uk and www.livingwitness.org.uk. A paper version of this calculator is available at www.quaker.org.uk/sustainability.

Transport

Travel by car

Do you drive a car?

How many miles do you drive per year?

miles

What type of fuel does your car use?

On average are your trips less than 3 miles, or more than 3 miles?

What is the fuel consumption of the car you drive?

  • High (25mpg)
    4x4

Flight

About how many hours do you travel by air each year (long or short haul)?

Energy in your home

To get your personal footprint for heating and appliances, enter how many people live in your home.

What type of home do you have?

Heating

How warm is your home?

How well is your house insulated?

  • Minimal
  • Well
    Loft, cavity wall insulation
    draughtproofing
  • Very well
    Floor insulation,
    double glazing,
    ventilation with heat recovery

What do you mainly use for heating your home?

How efficient is your heating?

  • Poor
    Old boiler (20+ years old)
  • Excellent
    New condensing boiler

Hot water

Do you have a hot water cylinder (not a combi boiler)?

How do you usually wash?

  • Bath/long shower
  • Quick shower
  • Flannel wash

Do you have a solar water heater?

What do you mainly use for heating water?

Appliances

How efficient are your appliances?

  • Very inefficient
    Unrated appliances,
    incandescent lights
  • Very efficient:
    All A or AA rated appliances
    and efficient lights

How many appliances do you have and how carefully do you use them?

  • Lots of appliances
    used often
  • Careful use,
    no clothes drier
  • Ultra frugal
    No TV, freezer, oven etc.

Do you use an oil-fired range cooker (like an Aga)?

Food

What sort of diet do you eat?

  • Serious meat eater
  • Typical UK
  • Vegetarian
  • Vegan

How much organic food do you eat?

  • Nothing organic
  • Nearly all organic

How much of your food is processed or imported?

  • Nearly all
  • Very little

What percentage of your meals do you eat away from home?

  • 50%
  • 25% (Typical UK)
  • Very few

Household waste

How much waste do you produce per week?

(Measured in black bin bags. The UK average is 23kg/wk of household waste - one full bin or two black bags)

How much do you recycle or compost?

  • Minimal
  • Some
  • Everything

How many skiploads of building/DIY waste does your household produce per year?

Housebuilding

The energy and cement used to provide materials and construct or extend a building produce CO2 emissions. There's no 'right' way to share these out over the lifetime of a building: we'll simply assume that the share decreases linearly over the first 50 years of the building's use, and is zero after that.

When was your home built?

Other goods and services

Greenhouse gases are emitted in the production and distribution of all the other goods (eg: clothes, furniture, electrical appliances) and services (entertainment, sport, telephone) that you buy.

How much does your household spend per month on other stuff? (clothes, furniture, entertainment)

  • Low
  • Average
  • High

Public services and non-profit organisations

Government and non-profit organisations provide public administration and services such as health and social care, schools, Quaker meetings, emergency services, prisons, the military etc. Doing this produces greenhouse gas emissions.

We estimate their contribution based on their share of spending to add approximately 2,400kg CO2 per person per year on average.

Next steps

First of all - take time to celebrate that you've worked through the calculator!

Then -

  • Send yourself a copy of your CO2 values for future reference. You can then revisit the calculator at a later date and compare the findings, so you can see what impact your changes have had on your carbon footprint.
  • Compare your findings with the UK average and averages from around the world. To avoid the worst effects of climate change, global emissions must fall to below 1.5 tonnes CO2 per person over the next 40 years.

Reduce your impact

Campaign for change

Your climate impact is not just down to you! The government and the services it provides produce a lot of carbon on your behalf.

See quaker.org.uk/speak-out for ideas of what to speak out about, and how to do it.
