Actions of various countries (London)
The London Green Olympics
Overview
The Committee for London 2012 has drawn these into five points: combating climate change, reducing waste, enhancing biodiversity, promoting inclusion, and improving healthy living.
Alternative Energy
By generating up to 50% of total energy requirements on the site itself and by using over 20% renewable energy,
The Olympic village will be 25% more energy-efficient and carbon emissions will be reduced by 50% for the whole development compared with current building regulations. This reduces emissions greatly.
This is done by:
1) 120-metre high wind turbine north of the park.
2) Specially designed combined heat and power plant (where heat from the power plant is transferred to the heater system such less energy is required for heating itself).
Water conservation
1)With water saving techniques, up to 20% less water would be used onsite.
2) There would be water 'recycling', similar to Singapore's NEWater concept.
Resources / Transportation
1) 90% of the materials leftover from demolition works will be reused or recycled
2) 50 km of new cycling routes and 30km of new walking routes will be built.
3) Walking, cycling and public transport will be promoted as the best ways to get to the events and there have even been talks of banning cars during the games.
4) Half of the construction materials will be transported to the Olympic Park by rail and water.
Special info
1) The stadium will also be demountable, meaning it can be disassembled, moved, and rebuilt in a new city. It will be largely bolted together, rather than welded, and break down into pieces that can fit on cargo ships. This new philosophy of “low impact” games and reusable stadia might afford poorer countries the opportunity to host future Games.
2) It has also begun to create new habitats for any wildlife that might be found on Olympic sites, and is recycling complete buildings to be re-assembled away from original Olympic sites
