Artificial forest plan to cut carbon

9:07 pm on 27 August 2009

British engineers say a forest of 100,000 artificial trees using filters to soak up carbon emissions could be established within 10 to 20 years.

The trees, each the size of a shipping container, are among geo-engineering ideas recommended in a report by members of the Institution of Mechanical Engineers, the BBC reports.

Lead author Tim Fox says prototype artificial trees already exist and could be mass produced and deployed in a relatively short time.

Technology to store the carbon would have to be fully developed.

The report also recommends putting algae that would remove carbon dioxide from the air during photosynthesis in transparent containers on buildings.

A third recommendation is to make roofs reflective, so they bounce sunlight back into space.
