The United Nations is proposing to make its main greenhouse-gas trading program more predictable to boost investment in projects that curb emissions, according to EcoSecurities Group Plc.

UN negotiators are seeking to create a system of precedent in the so-called Clean Development Mechanism market, with set processing timetables when project developers submit documents to the CDM executive board, said Marc Stuart, co-founder of Dublin- based EcoSecurities, which has more emission-reduction projects than any other company. The board is the mechanism¡¯s regulator.

¡°This will create a body of precedent regarding decision- making,¡± Stuart said late yesterday, citing documents circulated in Poznan, Poland, where the UN is this week holding climate- protection talks. ¡°We are seeing the creation of a culture of accountability.¡±

The International Emissions Trading Association, a Geneva- based lobby group, in October called for the UN board to drop its role in approving each carbon-reduction project and streamline decision-making. The program was taking months to approve some projects, slowing development of wind farms and industrial gas- destruction plants that curb heat-trapping gases.

Under proposed changes, the board would need to set ¡°timelines¡± when undertaking so-called completeness checks during project registration, as well as when processing revised plans to measure greenhouse-gas reduction, Stuart said.

The UN¡¯s emission-trading market is the world¡¯s second- largest, after the European Union program.
