London, Oct 30 (IANS) Former US vice president Al Gore, who is known for his climate conservation campaigns, has been accused of not switching off his car engine while he gave an hour-long lecture on environment in Sweden, a media report said Saturday.

It is alleged that Gore left his car running for almost an hour while he spoke at the School of Business, Economics and Law in Gothenburg, Sweden Wednesday, British newspaper Daily Mail said.

His mistake was compounded further by the fact that he had asked his distinguished guests to attend the event by public transport in order to minimise carbon emissions.

According to environmental website Climate Depot, Gore arrived at the event in a rental car from the airport and did not shut off the engine while he spoke.

Swedish law prohibits – for environmental reasons – any car engine being left running without its driver for more than 60 seconds. The fines for breaking that law are severe but it appears Gore has not been fined, the daily said.

Gore, the joint winner of Nobel Peace Prize along with the UN’s Intergovernmental Panel on Climate Change (IPCC), is the co-founder and Chairman of Generation Investment Management, a firm that focuses on a new approach to sustainable investing.
