Develop and assess global / national / sectoral mitigation pathways for their general use in project work., Support evaluation of country pathways and policy packages (e.g., NDCs and related plans), including comparisons against Paris-aligned benchmarks and pathway features such as overshoot, CDR, methane and other super-pollutants., Maintain and help evolve the Climate Action Tracker (CAT) scenario and assessment workflows, including routine running, documentation, and ongoing maintenance of global aggregation, equity, and country-level modelled pathway assessments, with links to temperature/climate-emulator pipelines where relevant., Support data harmonisation and downscaling workflows as backup capacity — ensuring that emissions and energy data from different sources are consistently processed, spatially and sectorally disaggregated, and ready for use across the broader assessment pipeline., Work with IAM scenario databases/ensembles (IPCC/IAMC-style formats, variable conventions, metadata, units) to produce policy-relevant indicators across emissions, energy, and key sectoral metrics., Support equity/fair-share and just-transition assessments of national pathways (e.g., effort sharing / fair-share ranges) and fossil fuel phaseout plans., Design and implement scenario diagnostics and quality checks (variable/region mappings, unit consistency, outlier detection, completeness checks) and document assumptions transparently., Develop and maintain reproducible, collaborative Python pipelines for scenario ingestion, cleaning, harmonisation, and analysis (version control, testing, documentation)., Contribute to shared team infrastructure (e.g., data warehouse, standardised datasets, mappings, metadata practices) and improve internal standards for scenario handling., Participate in the development of methods and approaches to define and evaluate global, national and sectoral climate action.
