Life Cycle Assessment
Thanks to its higher efficiency in the use phase compared to the previous model, the new GLC 220 d 4MATIC (Combined fuel consumption (diesel): 5.5–5.0 l/100 km; combined CO₂ emissions: 143–129 g/km*) produces however over the whole lifecycle, 20 percent (approximately 10 tons ) lower CO₂-emissions than those of its predecessor. Regarding the NOx-emissions they could be reduced by 27 percent  compared to the previous model.
The plug-in hybrid model GLC 350 e 4MATIC (Combined fuel consumption (petrol): 2.7–2.5 l/100 km; combined CO₂ emissions: 64–59 g/km*) combines a 85 kW (116 hp) electric motor with a four-cylinder petrol engine displacing just under two liters with 155 kW (211 hp).
In the production phase the GLC 350 e 4MATIC gives rise to a higher quantity of CO₂-emissions especially caused by the additional hybrid-specific components. Over the entire lifecycle comprising manufacture, operation over 200,000 kilometres and recycling, however, the plug-in hybrid has clear advantages. External charging with renewable electricity from hydro power can cut CO₂ emissions by around 62 percent (41 tonnes ) compared with the GLK 350 4MATIC.
 Status environmental certificate/certificated values: 2015
In comparison with the predecessor the new GLC 220 d 4MATIC reveals several differences in the material mix.
Due to lightweight construction measures in the areas of body shell and chassis, the new GLC 220 d 4MATIC has an approximately 6 percent lower steel content, while the proportion of light alloys rises around the same value.
Secondary and renewable raw materials
In the base variant of the GLC, a total of 34 components with an overall weight of 41.3 kilograms can be manufactured partly from high-quality recycled plastics. Thus, the weight of secondary raw material components could be held on the same high level of the previous model.
Typical areas of use are wheel arch linings, cable ducts) and underbody panels, which consist for the most part of polypropylene.
For the interior ornamentals in the new GLC, so called finem line veneers are used. Thereby, mostly sheets of veneers made of peeled veneer were glue-laminated to veneer blocks in a special process and sliced to veneers again under variation of the cutting angle. This results in wood reproduction, for example with stripe-, flower- or vein structure but also exclusive design veneers with fantasy decors.
By using this process it is also possible to replicate protected tropical wood with domestic types of wood (lime, poplar) and thereby protecting the environment and support domestic timber industry.
Together with the ornament suppliers and the different veneer producers, individual designs could already get realized and veneers developed, which satisfy the high technical requirements in the automotive sector.
In the new GLC, a total of 70 components with an overall weight of 24.9 kilograms are made using natural materials. The total weight of components manufactured with the use of renewable raw materials has thus increased by 21 percent compared with the preceding model.
Allergy-tested car cabin
The new GLC has also been awarded the Seal of Quality from the European Centre for Allergy Research Foundation (ECARF).
The ECARF Seal of Quality is used by ECARF to designate products that have been scientifically tested and proven to be suitable for allergy sufferers.
