In terms of Principle 16 of the Rio Declaration, National authorities should endeavour to promote the internalisation of environmental costs and the use of economic instruments, taking into account the approach that the polluter should, in principle, bear the costs of pollution, with due regard to the public interests, and without distorting international trade and investment.
第16條原則：國際化的環境成本 國家當局應努力促進環境成本內部化和使用經濟手段，同時考慮到這樣的做法，即污染者原則上應承擔污染費用，並適當考慮到公眾利益和不扭曲國際貿易和投資。
