The HuellaChile Programme is an initiative created with the purpose of promoting the management of greenhouse gas (GHG) emissions in the private and public sector. Since its launch in 2015, it has promoted the voluntary participation of both private and public entities in the quantification, reporting and reduction of GHGs. The programme is implemented by the Ministry of Environment of Chile, and supported by United Nations Development Programme (UNDP) through the NDC Support Programme. HuellaChile entails three lines of action: i) the web platform for GHG emissions quantification linked to the Pollutant Release and Transfer Register (PRTR); ii) technical support for climate change capacity building within organisations; and iii) a system for recognising organisations according to their level of involvement, which consists of four hallmarks: quantification, reduction, neutralisation and excellence. The programme is considered good practice as it enjoys the support from the highest levels of government, is voluntary, free, easy to use and adaptable to any participating organisation, and based on international measurement standards.
