Air quality constitutes a nation- al priority for environmental management. Thus, various actions will be implemented, including: new atmospheric decontamina- tion plans; regulations applied to the public and private transport system; work with communities to improve household energy ef- ficiency; and setting emission and quality standards for the main industrial pollutant issuers, among others. En este contexto, Chile se compromete a: Contribution to Mitigation NÂº2 (M2) M2) Reduce total black carbon emissions by at least 25% by 2030, with respect to 2016 levels. This commitment will be implemented primarily through national policies focused on air quality. In addi- tion, it will be monitored through permanent and periodic work to improve information available in the black carbon inventory.
