In regard to the elaboration of the NGHGI, the country operates through the National GHGs Inventories System (SNICHILE), whose main objective is the update of the NGHGI. SNICHILE maintains a permanent line of work with the Ministries of Agriculture, Energy and Environment, which have been equipped with technical and basic financial resources and have appointed personnel for the periodic revision of the inventory. Nevertheless, as the periodic elaboration progresses, it is more necessary to strengthen the intersectoral interaction among the data providers, their verification of estimation of emissions and the compilation of results. Moreover, as for technical capacities, more than the requirement for new ones, is the need to maintain the existing ones through institutional agreements that allow the SNICHILE to address situations like personnel rotation due to change in administration. The recent NDC update, aligned with a long-term vision set out by the country, has increased the ambition of climate action nationally. This not only means that the country will have to evolve in order to reach its environmental and climate objectives, but it also poses great challenges and new requirements associated to the acceleration of decarbonization of the productive sectors and the environmental awareness of the population to achieve profound behavioural change. The process of decarbonization of different sectors reveals the need for governance allowing the articulation of the sectoral efforts around the MRV systems in order to strengthen the quality of information provided, standardize the methodology, improve transparency and avoid double counting. The key to achieving this is to improve sectoral capacities. At the same time, it is important to support initiatives such as HuellaChile, platforms for mitigation action records and the National Prospective System currently in development, as well as exploring mechanisms that foster voluntary climate action and allow for progress on issues and key sectors to reach GHG neutrality by 2050.
