In the first-quarter 2012, the amount of CO2 emitted by PSA Peugeot Citroën vehicles declined by 2.1 grams compared with 2011, making the Group the leader in Europe with average CO2 emissions of 125.5 grams per kilometre.
This 2.1-gram reduction validates the Group's environmental strategy, which is based on three complementary pillars:
- Optimising petrol and diesel internal-combustion engines by deploying HDi engines equipped with particulate filters (5.7 million vehicles on the road by the end of April 2012) and developing a new 3-cylinder petrol engine that emits less than 100 grams per kilometre for the new Peugeot 208 in 2012.
- Deploying hybrid technologies: by standardizing Stop&Start technology across the Peugeot and Citroën line-ups (380 000 vehicles equipped at the end of April 2012) and by launching new diesel hybrid models – the Peugeot 3008 HYbrid4 and 508 RXH and the Citroën DS5 HYbrid4 – with carbon emissions of 95 to 107 grams per kilometre.
- Marketing electric vehicles (the Peugeot i0n and the Citroën C-Zero were launched in December 2010). The technological advances made by the Group enabled it to maintain its environmental leadership.
In 2011, PSA Peugeot Citroën was top ranked in Europe in the segment of vehicles emitting less than 111 grams of CO2 per kilometre with a market share of 21.1%. The decline in emissions continued in first-quarter 2012, when the Group's market share in the segment stood at 20.9%.
