This means that a new greenhouse costing $20,000 which has a useful life of 25 years would be depreciated at a rate of 8%, twice the straight line rate, of the undepreciated value each year as compared to taking 4% of the original cost each year as the annual depreciation allowance.

Naturally-occurring greenhouse gases, such as carbon dioxide and methane, allow solar radiation to reach the Earthâs surface, while trapping radiation from the Earth on its way back out to space.
