'Research In Motion' is at the bottom of a list of the greenest electronic firms of the world. The 'BlackBerry maker' has found a place for the first time in the 'Greenpeace Guide to Greener Electronics', which is being published every three months.

RIM has been blamed for not resorting to energy efficiency standards. Its products are considered to be energy inefficient. It has not made any effort to make use of renewable energy. On the whole it lacks a clean electricity plan.

The guide helps in comparing reputed companies dealing in mobile phones, PCs, TVs etc.

HP tops the list as it is making serious efforts to reduce carbon emissions. Tom Dowdall of Greenpeace International expects other companies also to do so.

Dell has improved its position from 10 to 2. That is mainly because of its strong policy against emission. In fact it has plans to reduce emission by 40% before 2020. In the meantime Nokia's no 1 position for the last three years has been disturbed. It has to be content with the third position.

The objective of the guide, introduced in 2006, was to restrict the companies from emission of Polyvinyl chloride (PVC) and brominated flame retardants (BFRs). Greenpeace has succeeded to a good extend in the case of mobile phones and PCs.

The environmental watch group has been quite strict in their expedition. The latest guide includes new criteria for conflict minerals, sourcing of paper and product life cycle.

An RIM spokeswoman informed Guardian that more initiatives can be expected from the company with respect to the environmental requirements.

A Nokia spokesman claimed that his company's position continues to be the highest among device and mobile manufacturers. The company will strictly follow the environmental policies advocated in the guide.
