LONDON, Sept 1 (Reuters) - A proposal to make carbon emissions auditors liable for issuing excess U.N. carbon offets would hurt the verifiers and could both cut supply and increase demand for credits, Point Carbon analysts said.

Under the U.N.'s clean development mechanism (CDM), companies can invest in emissions reduction projects in developing countries and in return receive carbon offsets.

The offsets -- called certified emissions reductions (CERs) -- can be traded and bought by emitters to offset their carbon dioxide output.
