The two principles are mutually reinforcing. For example, if we have a predictable environment, we are more likely tohave fair burden sharing, because people and businesses are aware of their responsibilities and are willing to cooperate toward sustainable goals. Fair burden sharing also contributes to predictability, because people will perceive changes to be fair if they apply equally to everyone. Within this framework, legislation and law enforcement should promote the reduction and restoration of environmental pressures; the protection of human health and the improvement of quality of life; the sustainable use of natural resources; the coordination of state tasks with environmental protection; international environmental cooperation; an active participation of the population in environmental protection; the adaptation of the economy to environmental requirements; as well as the establishment and development of the environmental protection institutional system and public administration. The means of fair burden sharing can be (i) a progressive tax system: those who earn more should contribute a greater proportion to the public good; (ii) higher taxation of polluting products, sharing of environmental costs; (iii) developed countries have a greater responsibility in combating climate change, and therefore should support developing countries.
