Average per UK household:

On average each UK  household has a carbon footprint of 10 tonnes per year. (http://www.carbonbrief.org/city-of-london-tops-uk-carbon-footprint-list)

Calculate you own footprint:

This number is highly dependable of where you live, as well as your lifestyle. Here is a link to a homepage, where you can calculate your own footprint, if you like: http://footprint.wwf.org.uk/

Footprint of some activities, goods and and appliances:

1) Return ticket London to Bangkok, per person in Economy; 3.25 tonnes; London to NY city; 2,0 tonnes, London-Malaga; 0.7 tonnes From: https://co2.myclimate.org/en/flight_calculators/new

2) ‘The Swedish Institute for Food and Biotechnology recently (1998 – ‘Screening life cycle assessment (LCA) of tomato ketchup: a case study’) examined the life cycle of a bottle of tomato ketchup. They found that tomatoes grown in Italy were sent to Sweden for processing before being poured into bottles imported from Britain made with ingredients sourced from Japan, Belgium, and the US. By the time one bottle travelled to a grocery store and finally to a kitchen table, the process had consumed 4,190 more units of energy than was contained in the ketchup. And it generated more than 5,000 pounds (2,27 tonnes) of CO2’.

3) ‘Sending even a short email is estimated to add about four grammes of CO2 equivalent (gCO2e) to the atmosphere. To put this into perspective, the carbon output of hitting “send” on 65 mails is on par with driving an average-sized car a kilometre. The culprits are greenhouse gases produced in running the computer, server and routers but also those emitted when the equipment was manufactured. It gets worse when you send an email with a large attachment, which puts about 50 gCO2e into the air’. From: http://phys.org/news/2015-11-carbon-footprint-email.html

4) Various appliances in a household:

5) ‘WRAP estimates that the total carbon footprint of food and drink consumed in the UK is 130 million tonnes CO2e per year. This is approximately equivalent to a fifth of UK territorial emissions, or 2 tonnes of CO2e per person per year’.

6) ’ Timberland Co., /.. / has assessed the carbon footprint of about 40 of the shoe models it currently sells. The results range from about 22 pounds to 220 pounds per pair.

The carbon footprint of a load of laundry done with Tesco detergent varies from 1.3 pounds to 1.9 pounds, depending on what form of detergent is used, the labels report. According to Procter & Gamble Co., the average American family does about 300 loads of laundry per year, or about six loads per week. That suggests a per-family carbon footprint from doing laundry of about 480 pounds per year, or about 10 pounds (4.8 kg) per week. And that doesn’t include running the dryer.

Patagonia Inc. ‘s Talus jacket looks like a naturalist’s dream. In fact, its carbon footprint is 66 pounds (More than 30 kg). That, Patagonia notes on its Web site, is 48 times the weight of the jacket itself’.
