Corporate Responsibility -A Consumer Goods Company Perspective 7th November 2005 Brussels “Europe Goes Alternative” Randy Stolt – Procter & Gamble http://www.pg.com/science/animal_alt.jhtml
Our Commitments • We improve consumers lives with high quality products that clean homes, enhance personal wellbeing and contribute to family hygiene and health • Our products are safe for our consumers, employees and the environment • We meet or exceed all applicable regulations
The Dilemma Regulations Scientific Progress Animal Use Safety Consumer Confidence Innovation Stakeholder Concerns
Our Approach We want to ultimately eliminate animal use for consumer goods We employ the 3Rs and any animal use is a last resort The majority of our safety studies do not use animals We ensure high standards of care We have invested significantly in developing alternatives We actively share our discoveries We collaborate to promote acceptance of alternatives

Importance of Dialogue, Cooperation & Collaboration • Across industry: • Sharing of resources • Common goals • Industry/Government: • Validation • Acceptance criteria • Industry/Academia: • Application of basic research • Support of research • Industry/Stakeholders: • Sharing concerns • Advocacy
What can Consumer Goods Companies bring to the Partnership? • A strong policy commitment to human and environmental safety • Experience in risk assessment • Operations in various regulatory environments from around the world • History of engagement on the 3Rs • Active cooperation within trade associations and with academia, regulators and stakeholders
