Life Cycle Assessment (LCA)

Certificate by Japan Environmental Management Association for Industry

Having established a proprietary LCA*1 system and conducted careful assessment of the environmental impact of its product at every phase, Mazda has confirmed the benefits of its clean-energy vehicles and newly introduced vehicles with current internal combustion engines.
In the LCA of the CX-5 conducted in FY March 2012, the CX-5 underwent a review by a third-party organization (Japan Environmental Management Association for Industry) and its conformity with the international standards (ISO 14040, ISO 14044) was certified.
The LCA is conducted in the same way for newly introduced vehicles, serving as objective and highly reliable proof that those new models are environmentally conscious throughout their entire lifecycles.
c Mazda intends to steadily expand the imprementation of LCA to new vehicles and confirm its environmental benefits.

* Calculated assuming a vehicle lifetime running distance of 110,000 km (13 years) and running under certain conditions.
* Results of evaluations are shown as an index. Figures for CO2 refer to metric tons; all other figures refer to amounts in kilograms. Indices are shown separately. In the graph, all indices are based on an index of 1 for the SOx emission volume of the previous model (A).
NOx: Nitrogen oxide
NMHC: Non-methane hydrocarbons
