Legislation in catalysis is vital for multiple reasons: 1. Environmental Protection: Catalysts often facilitate reactions that reduce harmful emissions or convert pollutants into less harmful substances. Regulations ensure that these processes are safe and effective. 2. Public Health: Ensuring that catalysts used in food production, pharmaceuticals, and other consumer goods do not pose health risks. 3. Industry Standards: Promoting fair competition and innovation while ensuring that companies adhere to safety and quality standards.
