PAT Scheme Impact and Carbon Liability Analysis for 48 Refineries in India and ASEAN: Facility-Level Data and Replication Code

This repository provides complete replication packages for five interconnected studies on carbon pricing and refinery decarbonization in India and ASEAN. STUDIES INCLUDED: 1. PAT SCHEME ECONOMETRIC ANALYSIS- Staggered difference-in-differences estimation- Finding: 24.1% reduction in specific energy consumption- 117 refinery-years (23 refineries, 2012-2024)- 115 million tonnes CO2 avoided 2. INDIA CARBON LIABILITY ACCOUNTING- First systematic quantification for Indian refineries- Base case: $13.1 billion total liability- Government exposure: $17.7 billion through PSU ownership- 6 scenarios × 4 pathways × 3 discount rates 3. INDIA REFINERY EMISSIONS DATABASE- First facility-level dataset for 23 Indian refineries- Sources: PAT scheme, Climate TRACE, company disclosures- 87.7% validation score- 55 CSV files with data dictionaries 4. TRANSITION PATHWAY MODELING- Cliff-year analysis under Paris-aligned scenarios- Decarbonization pathways 2025-2050- Employment and regional impact assessment 5. ASEAN REGIONAL ANALYSIS- 25 refineries across Singapore, Thailand, Indonesia, Malaysia, Vietnam- Regional liability: $20.3 billion- Novel finding: Ownership structure predicts policy stringency KEY METRICS:- 48 refineries analyzed- $33.4 billion total carbon liability- 45+ Python scripts- 58+ CSV data files- Full methodology documentation REPOSITORY STRUCTURE:- zenodo_upload/ - PAT scheme replication package- india-refinery-carbon-liability/ - Liability calculations- india-refinery-emissions/ - Emissions database- india-refinery-transition-analysis/ - Pathway modeling- asean-refinery-carbon-analysis/ - Regional analysis All code runs on standard hardware (16GB RAM) using publicly available data.
