This report draws together the key strands of analysis and results from capacity support activities undertaken as part of the “Ambition to Action” (A2A) project in Argentina between March 2017 and October 2019. Overall, the A2A project supported NDC processes in partner countries with a view to accelerate implementation of current NDCs and inform the setting of more ambitious NDC targets for upcoming NDC cycles. The underlying rationale of the project was to support policy makers to better understand the broader implications of higher ambition in key NDC sectors by comparing alternative sector pathways in terms of their socio-economic impacts and technical implications. The analysis involved the development of assessment tools to allow for the quantification of impacts or so-called co-benefits and was undertaken in close consultation with local experts.
