Summary for Decision Makers from the first regional assessment of short-lived climate pollutants in the Latin America and Caribbean (LAC) region. Through this assessment, policy makers and implementers will be able to better quantify and understand the relevant emissions in the region; identify which measures are most important for delivering near-term climate and air pollution benefits; and estimate the reductions in regional air pollutants that could be achieved by implementing these measures, with associated health and crop-yield benefits for the LAC region.
