INTRODUCTION Once a government has defined its environmental goals, it can execute them by means of different policy instruments. The following environmental policy instruments can be distinguished (Dente, 1995; Golub, 1998; OECD,1989): (i) instruments of social regulation, such as transfer of information (environmental education, environmental labels, environmental impact reports, etc.), self-regulation (environmental policy agreements, self-control), and environmental care systems; (ii) instruments of financial aid, such as subsidies, soft loans, and fiscal incentives (investment deduction, tax reduction and tax exemption); (iii) instruments of planning (Deketelaere, 1997, I), such as macro-planning and micro-planning, binding planning and non-binding planning, sectoral planning and non-sectoral planning; (iv) instruments of direct regulation, such as permits, prohibitions and restrictions, and different sorts of requirements (quality-demands, product-demands, emission-demands, design demands, construction demands and production demands); (v) instruments of market regulation (Baumol, 1988; Helm, 1991; Guppes, 1992; Jenkins, 1992, II; OECD, 1989), such as liability rules, marketable emission rights, deposit and refund system, enforcement incentives and environmental levies. In this contribution, each of these environmental policy instruments will be analyzed in general. After that, the instruments which have already been used in European environmental policy will be examined. Finally, attention will be paid to the use of fiscal instruments in European environmental policy.
