Motorists looking for eco-friendly car insurance should do their homework as insurers "blow hot and cold" on premium charges, claims an analyst.
Some drivers could risk fluctuating premiums if they opt for one of the green car insurance deals currently on the market, according to a price comparison site.
The environmentally-friendly car insurance usually enables drivers to offset their carbon emissions or offers discounts on greener vehicles, but moneysupermarket.com contends that such incentives could be counterbalanced by "highly volatile" premiums.
"What might look like a bargain one week could double or even treble in price just days later," states Richard Mason, director of insurance at the firm.
He adds that the site advises drivers looking to contribute towards tackling climate change "not to assume that green car insurance is the best place to start".
The expert also asserts that eco-friendly car insurance providers should focus on offering financial incentives such as cheaper premiums.
Meanwhile, Ford recently announced that its vice president is now the owner of its 150th green flexible-fuel vehicle in the UK.
