- Institution of Mechanical Engineers publish Geo-engineering Report. Practical initiatives examined include artificial trees and energy from algae. August 27  Artificial or Mechanical Trees: "This is the Institution’s preferred concept of geo-engineering and works in a similar way to natural trees absorbing CO2 but will be several thousand times more effective. The report states a tree, manufactured at a cost of $20,000 dollars or circa £15,000 per unit could remove as much as 10 tonnes of CO2 a day. Indeed, if just 100,000 were created this would be sufficient to capture the whole of the UK’s current emissions from non-stationery and dispersed emissions (ie transport pollution). The ‘mechanical forests’ could be planted in areas such as our own M25 or even the North Sea!"
