BEFORE AFTER THE IMPROVEMENTS
  The Smart car is lighter than a conventional car so uses less material and less fuel.  An additional bonus is that all of the external panels can be easily changed, allowing for the colour and style to be upgraded.

Katie's lamp not only looks good in her bedroom, it also meets lots of sustainable design criteria. Itís a lovely example of social design because slides of her family were used to make the shade, itís economically sustainable, costing very little whilst maintaining skills. It's also environmental as it uses a wide range of objects collected from friends, family and recycling bins e.g. old photographic slides, a shower rail, a mobile phone charger, washers and a coat hanger. The only thing she bought was the LED bulb.

Petrol or diesel are swapped for muscle power.  This keeps the user fit and eliminates toxic fumes.

Walls built of rammed earth, without using cement, have a much lower environmental impact than concrete or brick walls because far less energy is used in their construction. The earth has to have the right proportion of clay which bonds it together when compressed. The Information Centre and Shop at the Centre for Alternative Technology has rammed earth walls which support the weight of the roof and are part of the passive solar heating of the building, as they store heat. Because they are internal walls they do not need to be rendered but external walls would be. There are thousands of buildings in the UK with earth walls, many of them more than a hundred years old.
