In addition, the ECLP establishes guidelines so that solutions based on nature (NbS) are considered, with special emphasis on environmental sustainability in the use of water in the face of threats and risks associated with droughts, floods and pollution, and the consideration of climate refuges. ; In the same way, guidelines are established on the assessment of risks and losses and damages associated with climate change, considering the vulnerability of each specific sector. In this way, the commitment to manage both the national Budget of greenhouse gas emissions for the years 2030 and 2050 will be binding, according to the goal of neutrality, in accordance with criteria of cost effectiveness and equity of charges, as well as the Sectoral budgets for greenhouse gas emissions for the year 2030 assigned to the sectors indicated in article 8. The emission reductions necessary to not exceed the respective sectoral budget will be achieved through the measures contemplated in the Sectoral Mitigation Plans (PSM) the which should be prepared by 2024. Chile responds to the call for greater ambition in climate action, considering the serious risk that climate change entails for people and ecosystems, by recognizing &quot;climate urgency&quot; as a principle in the LMCC, incorporating more specific sectoral and territorial commitments, relevant and anticipated.
