Only cars with less than 120g/km of CO2 emissions will be able to use the eco2 badge, which can currently be seen on the Renault Clio, Renault Lagune, Renault Megane and Renault Grand Scenic.
This is in contrast to the criteria of sub-140g/km of CO2 emissions previously used by Renault’s eco2 cars.
Under the new criteria, all models using the eco2 badge in the Renault range will be built at a plant that meets environmental targets.
All cars much also contain at least seven per cent recycled plastic compared to the five per cent currently used. Finally, all cars have to be designed in a way that allows 95 per cent of their mass to be recovered at the end of the car’s life.
Under the new criteria, eco2 badge cars will include Renault’s small car range such as the Renault Clio, which boasts CO2 emissions of 94g/km when the dCi 88bhp engine is fitted with an ECO pack. Prices for the eco2 Clio start from £12,450 on-the-road.
Non-ECO pack models deliver 106g/km of CO2 emissions for both three- and five-door versions and will also be allowed to wear the eco2 badge.
The eco2 range will be expanded further later in 2011 when the first of Renault’s four electric cars arrive on the market.
The Renault Kangoo Z.E. van, Renault Fluence saloon, Renault Zoe supermini and Renault Twizy mobility solution will all use an all-electric powertrain and as such, will bear the eco2 badge.
Most car manufacturers use an eco signature to identify the most efficient and lowest CO2-emitting vehicles in the range. Eco signatures are also designed to allow customers to see the cars that theoretically, are the cheapest to run in the UK.
