A workshop was held in Santiago, Chile, in March 2017, gathering experts in emissions from different countries in South America, Europe and the USA. Current status of emission inventories in five South American countries (Argentina, Brazil, Chile, Colombia and Peru) was presented and discussed. This information will be summarized in a document that will be used to seek international funding to generate a consistent emission inventory for each one of these South American countries. National emission inventories in South America are prepared as part of the obligations of these countries to the United Nations Framework Convention on Climate Change within the framework of their national communications. These inventories include the emissions of greenhouse gases as well as non-GHG gases subject to complementary reporting under the Convention. Several pollutants with important impact on climate change and air quality are not included in these estimates. Emission inventories developed in different Latin America (LA) countries are typically developed at national level, providing an annual total, not necessarily for all criteria pollutants and without information on spatial and temporal emission patterns. There are also inventories for a number of LA cities, particularly large urban conglomerates, but these are not necessarily consistent with the corresponding national inventories. There is need to harmonize these estimates, and to fill the gap associated with the knowledge of spatially distributed and temporally disaggregated emissions. A network was established between members of the LA Emissions Inventory Group (LAEIG) from five countries (Argentina, Brazil, Chile, Colombia and Peru) and international researchers with the aim to build a consistent and shared emission inventory in the near future for these five countries.
