Living a one tonne life: update on research

Update on this research received: Could a ‘One Tonne Life’ Make it Possible for Households to Reduce CO2 Emissions to a Level That Would Avoid Climate Change?



· Transport emissions drop more than 90%



· CO2emissions produced in the home halved



· Food carbon emissions reduced 84% by going vegan



· Manufacturing of house and goods prevents ‘One Tonne’



Stockholm, Sweden; Monday, 13thJune 2011: “One Tonne Life”, a collaboration project between A-hus, Vattenfall, Volvo Cars and other partners has shown that households could reduce their carbon output from 7.3 tonnes per person to a stable 2.5 tonnes per person, living a comfortable everyday life. Furthermore, more extensive changes prove that it is possible to get this figure down to just 1.5, a level that could help us become carbon neutral and avoid serious climate change according to ‘A One Tonne Future’.



In January 2011, Swedish family, the Lindells, embarked on this six month groundbreaking project to find out if they could reduce their carbon emissions to hit this important target. They were helped in a variety of ways, not least with a climate-smart house featuring solar cells on the roof that were used to recharge the electric car parked in the driveway. The family – father Nils, mother Alicia and children Hannah and Jonathan – undertook this inspiring journey which involved moving to a new, climate smart house and examining each of their everyday habits to find out where they could reduce or, indeed, eliminate their carbon emissions.



The family report that with their energy smart house, appliances, energy meter and electric vehicle, reducing their emissions to 2.5 tonnes did not require any major compromise in their everyday lifestyles. After that, however, things got tougher and living at the 1.5 tonne level was a tough compromise.



The family made most progress in transport and electricity consumption. Emissions from transport dropped by more than 90%, mainly due to the family’s Volvo C30 Electric being recharged with electricity from hydro-power. The family’s house, built by A-hus, produces its own electricity and,with supplementary renewable electricity from hydro-power, carbon dioxide emissions from purchased electricity reduced to almost zero. All told, carbon dioxide emissions from the family’s home were more than halved compared to their emissions level in their previous home.



The family also made immense progress through their eating habits. By meal planning and being more informed about the food we eat, varying the choice of meat and eating more vegetables, it is possible for people to reduce carbon dioxide emissions. Towards the end of the trial period, the Lindells ate only vegetarian dishes, and dairy produce was replaced with soya and oat-based alternatives.



In order to reduce their emissions still further, in the final 1.5-tonne week the family reduced the size of their home by closing off one room. They went without TV, shopping and eating out. However, their “rucksack” of 900 kilograms stopped them from reaching the one tonne target. This “rucksack” consists of the CO² emissions that take place when various products are manufactured, such as the house, solar panels, car, furniture and clothes. However, they demonstrated that it is possible to get very close to one tonne, however it does involve a change in lifestyle and the information to make the right changes.



Key features of the One Tonne house



The wooden “One Tonne Life” house has triple-layer walls with exceptional insulation, minimal air leakage and low-energy windows and doors. Through its solar photovoltaic system the house is a net producer of energy. All electricity not consumed by the family was fed into the national grid or used to recharge the electric car. The family’s Volvo C30 Electric emits no carbon dioxide at all when recharged with renewable electricity.



Household appliances account for up to half of a normal household’s total energy consumption, the house is equipped with the latest energy saving appliances from Siemens. To help track progress the Family had an ‘Energy Watch’ system that registers the power usage and compiles data for analysis. This allows consumption to be followed in real time or over a selected time period and learn how their personal habits influence electricity consumption. Experts from the Chalmers University of Technology followed the family in order to ensure a reliable calculation of the family’s carbon dioxide emissions. Methodology can be found here.

One Tonne Life

One Tonne Life

Is it possible to live a One Tonne Life today?
One tonne of carbon dioxide per person and year is a major challenge bearing in mind that the global average today is about seven tonnes.
However, house specialists A-hus, power supplier Vattenfall and Volvo Cars believe that with the right know-how, the right technology and confident, consistent behaviour it is possible for the test family to approach the one-tonne target figure without departing significantly from its regular lifestyle or standard of living.
Much of the technology and the solutions the family will use are already available to the general public or will be in the near future. The necessary preconditions are there – right now!

According to The Independent 'Three Swedish companies are looking for an 'average' family to live in Stockholm for six months and reduce their environmental impact.' Click the link to find out more.

Promoting re-use with award-winning art by local artist and designer

A local reclamation company are working to raise the profile of re-use. They have started working with award-winning Bristol artist Claire Danthois who re-uses reclaimed materials in her designs. See
http://www.rmills.co.uk/

Bristol's Claire Danthois is at the forefront of the sustainable design movement and expresses her personal belief in environmental responsibility through the creation of provocative, functional sculptures built exclusively from reclaimed materials. Danthois’ philosophy is rooted in the belief that the former lives of found objects provide a rich context and an intrinsic beauty that enhances her work.

Finding inspiration in human anatomy and the natural world, Claire began working with metals during her time at Plymouth University, shaping furniture into organic forms, using steel rods. This experience fuelled Claire’s further exploration in building three-dimensional forms, ultimately resulting in her reclaimed timber series titled "Once Discarded"(see pictures). Danthois first gained recognition in 2007 for the "Once Discarded" collection; the "Once a Door" chair in particular was awarded first place in British newspaper The Guardian’s "Top 10 Eco Furniture" article and METRO Home magazine named it one of "Finest Recycled" designs of the year.

Claire’s works have been displayed primarily in London, at the Eco Design Fair, New Designers Fair and The Islington Contemporary Art Fair, to name a few. In late 2007, Claire’s award-wining piece, "Once a Door", was exhibited at the Utterubbish SIT UP [re]Design in Singapore. A recent project was a collaboration with Newton Vineyard entitled "Re-Inspired Elements: A Tasting Installation."
　
Robert Mills Ltd is one of the largest suppliers of architectural and decorative antiques and is one of the original reclamation companies in the UK. In partnership with Robert Mills Architectural Antiques, Claire is currently producing custom commissions of her award-winning "Once a Door" chairs. In the coming year Claire aims to create a series of public art pieces in partnership with communities that share her hope for a more sustainable future.
