Soul | Results from environmental assessment and 3rd party certification

Kia Motors and Environment

Sustainability and environmental impact are the two factors that are present in the design of every new Kia car. In this regard, Kia assesses quantitatively the impact of each new car on environment throughout its life and strives to develop cars with less impact on environment based on findings from the assessment.

Learn more about how the 2nd generation Soul has reduced its impact on the environment.

Environmental assessment of the 2nd generation Soul

We performed lifecycle assessment to determine how much the Soul has improved its environmental impact through a comparison with the 1st generation Soul. The Soul with an 2.0 gasoline engine and 6 speed automatic transmission, which is the most popular model in the U.S., was chosen for the test. For an accurate comparison, it was assumed that the car would be disposed of after 150,000 km of normal traveling from its production.

The methodology used for the assessment was based on TRACI 2.1 developed by US EPA, which is designed to best suit U.S. conditions.

Results from Environmental Assessment | Global Warming

Gases like carbon dioxide and methane cause greenhouse effect and accelerate global warming. Compared with the 1st generation Soul, the second generation Soul, despite an increase its weight (of 67kg or 5.3%), reports improved fuel efficiency and reduced CO2 emissions (by 14g/mile). This can be translated into a decrease of 4 percent in its impact on global warming over its lifecycle.

This graph shows the impact of the 2nd generation Soul on global warming has decreased around 4 percent compared to its predecessor.

Results from Environmental Assessment | Resource Consumption and Others

Results from the assessment reveal that the 2nd generation Soul has less impact on the environment that its predecessor in terms of resource consumption, oxidation and smog generation. Eutrophication, however, was found to be greater for the 2nd Soul.

More materials used for the 2nd generation Soul increases the negative impact on the environment. This stems from the application of more features to the car. Some aspects of the environment have to be compromised when we try to meet diversifying customer needs.

Still, the improvement in fuel economy and the reduction in emissions are large enough to offset such compromise. It can be said therefore that the overall environmental performance of the 2nd generation Soul has improved.

This graph shows the impact of the 2nd generation Soul on use of resources, acidification, smog and other enivironmental issues has decreased compared to its predecessors.

Environmental Certification by a Third Party

To verify that the results from the environmental assessment of the 2nd generation Soul are sufficiently objective and reliable based on suitable data, we employed an independent certification body - TUV NORD.

TUV NORD, based in Hannover, Germany, is a highly trusted certification body that provides large scale consulting, inspection and certification services in regards to environmental impact.

TUV NORD certified that the methodology and the process applied to the assessment of the 2nd generation Soul's environmental performance are in compliance with ISO 14040.

Leap towards a sustainable future

Kia Motor will spare no effort in developing eco-friendly products. As the assessment results show, Kia's cars are gradually transitioning towards a more sustainable future. Your support is appreciated.

Lifecycle assessment

Lifecycle assessment is a method of quantitatively measuring resources and energy used in the material gathering, manufacturing, use and disposal of products and the waste from them through the product lifecycle and evaluating the potential impact on the environment (ISO 14040/14044).


    A methodology to assess impact on environment using largely U.S. data (devised by the U.S. Administration of Environment)
