CEPE’s “Sustainable Development” Charter defines

sustainability for the industry

Brundtland Report (1987):

»Sustainable development is development that

meets the needs of the present without

compromising the ability of future generations to

meet their own needs«.

“CEPE members consider a development to be

sustainable only when its impacts on the three

pillars of sustainability, being people, planet and

prosperity, have been assessed and when they do

not violate the below described principles

or the conditions for these three.”

“It is CEPE’s opinion that Life Cycle Assessments

(LCAs) form the basis on which decisions on

sustainable developments should be made.”

CEFIC’s “To do list for product sustainability”

• Encourage lifecycle thinking

• Engage with your customers and suppliers

• Understand exactly where your product or service

adds value

• Know where your environmental hotspots are

• Measure, monitor and manage

• Turn a waste into a resource

• Keep up to date with policy and regulatory

requirements

• Use sound science in your decisions

• Ensure transparency

publication on product sustainability

Conclusion



Life Cycle Assessment is a standardized method for

evaluating potential environmental impacts

Raw

material

Energy

Production Product

Distribution Use „Disposal“

2nd life

• Evaluation of inputs, outputs and the

potential environmental impacts of a

product system throughout its life cycle

• Life cycle means from raw material

acquisition or generation from natural

resources to final disposal

• Different environmental impact

categories can be assessed, e.g.

Global Warming Potential (Carbon

Footprint, measured in kg CO2-Equiv.)

Life Cycle Assessment (LCA) according

to ISO 14040 / ISO 14044


Example 1: LCA study on powder coatings shows

advantages for polyester compared to epoxy

Example 2: LCA “Cradle-to-Grave” reveals

environmental benefits of cold spray plastic

compared to three other major road marking systems

LCA of road marking spray systems

• Scope: “Cradle-to-grave” per 10 years per km

• Review by external expert panel according to ISO 14040/44


Example 3: Silicone industry recently calculated GHG

emission savings enabled by product applications

The “Benefit/impact ratio”:

Ratio of the benefit realized by the silicone

product vs. GHG emissions from the

production and end-of-life phases of the

silicone product.

Meta-analysis of LCA studies shows no clear picture

when evaluating biobased vs. conventional materials

Main findings of a meta-analysis of 44 LCA studies:

Biobased materials generally lead to:

- Reduced primary energy demand and GHG emissions

- Increase of eutrophication and stratospheric ozone depletion

- No clear trend re acidification and photochemical ozone formation

But:

- General conclusions difficult due to variability in the results

- Additional land use impacts were not quantified, but strongly

recommended for evaluation, e.g. biodiversity loss and GHG

emissions by deforestation

Evaluation of Biodiversity loss: e.g. guidelines by WBCSD or

“European Business and Biodiversity Campaign”

Evaluation of GHG emissions by deforestation: e.g.

guidelines by GHG Protocol or ISO 14067

1. Biobased coatings are not sustainable per se

2. Life Cycle Assessment studies can help to

understand and improve sustainability characteristics

3. Collaboration along the value chain is essential
