This Final Report summarizes the IIASA contributions to the SLCP Assessment for LAC project.

IIASA has delivered all agreed outputs with respect to modelling work required to develop baseline and mitigation scenarios where key SLCP mitigation measures were identified. The results in form of gridded emission fields were provided to the impact and climate modelling groups involved in the project.

The developed protocol for data collection allowed to acquire a harmonized data set on emissions within the region for which a number of issues were identified and it was compared with the GAINS database, leading to its improvement. This exchange between the national experts and IIASA modelling team opens up a possibility for further collaboration where also ROLAC will play a role as the information has been stored there. The final historical inventories have been harmonized with the global GAINS database and served development of scenarios.

While the GAINS model has been further developed to consider specific LAC circumstances and availability of new data, the baseline and mitigation scenarios were developed in a consistent way with the global UNEP/WMO Assessment allowing a comparison of the results. The finally selected SLCP measures include additional options which were not part of the global assessment, for example, reduction of gas flaring, introduction of Marques brick kilns, shale gas options, and options to mitigate HFCs.
