(2) The purpose of the planning system for climate change policy is to determine the re- duction targets for greenhouse gas emissions and the goals of adaptation to climate change, as well as the measures required to reach these goals and targets in different ad- ministrative branches, as provided below in more detail. (3) The goal of the planning system for climate change policy is to ensure that the total anthropogenic emissions of greenhouse gases into the atmosphere is reduced in Finland by at least 80 per cent by 2050 compared to 1990 levels. If an international treaty binding on Finland or European Union legislation includes a total reduction target for greenhouse gas emissions set for 2050 that differs from that mentioned above, it must be used as the basis for the long-term emissions reduction target of the planning system. The goal of planning the adaptation to climate change is to promote the management of risks caused by climate change and sector-specific adaptation to climate change. (4) The goal of drawing up climate change policy plans is to attempt to mitigate climate change and adapt to it in a cost-effective way. The goals and measures relating to the miti- gation of climate change and adaptation to it included in the plans shall be based on re- search data, so that the progression of climate change, its probable positive and negative effects, the related risks and hazards, and the possibilities to prevent accidents and limit their adverse effects are taken into account. In planning related to agricultural production, it shall be ensured that the measures related to mitigating climate change are planned and implemented so that they do not compromise domestic food production or global food security.
