A long-term global goal for emission reductions [with related medium-term goals]
17. The shared vision includes a long-term [aspirational] global goal for emission reductions that is based on best available science [and economic analysis] [, incorporating the ecological rationality of natural systems as one of its guiding principles, as this ultimately affects the dynamics of planet Earth and its climate, and to which the economic rationality should be subordinate], recognizes the scale and urgency of the challenge as outlined in the Fourth Assessment Report of the IPCC and provides direction to long-term cooperative action, making it sufficiently effective to bring about the deep cuts in global emissions required to achieve the ultimate objective of the Convention [with flexibility and diversity of nationally appropriate actions]. The emission reduction goals set for the short and medium term should enable the fulfilment of this long-term goal.
