Tidligere krav til industrien, f.eks. vedrørende indførelse af katalysatorer, viste tydeligt, at hvis kravene bare er tydelige, så tilpasser industrien sig til virkeligheden og omstiller sin produktion for at opfylde kravene.
Earlier requirements on industry, such as in the introduction of catalytic converters, clearly showed that if the requirements are clear, industry adapts to the reality and converts its production to meet the requirements.
