Fossil CO2 per person: Global Carbon Project, Global Carbon Budget fossil CO2 dataset 2026v11 (Zenodo 10.5281/zenodo.23667912), tonnes CO2 per person; real GDP growth: IMF World Economic Outlook, October 2026 (NGDP_RPCH, annual %). Both read from the publishers' files and API via the progrss vault (GUIDELINES §4.11; live re-read failed: web access refused this run). GDP growth 2014–2024 is the annual growth rates 2015–2024 chained (progrss calculation). Countries with 1 million+ people (World Bank WDI SP.POP.TOTL, 2024) and all ten growth years (153). Estonia 14.29 t (2014) → 5.95 t (2024), −58.4%; GDP +22.7%; 2025 preliminary 5.61 t. Next-largest falls among the 142 countries whose GDP grew: Finland −38.9% (8.72 → 5.32 t), Angola −37.2%, DR Congo −34.8%, Denmark −32.1%, United Kingdom −32.1%. Correlation across 153 countries: Pearson r 0.41, Spearman 0.54; dropping any one country gives r 0.40 to 0.44. Restricted to the 97 countries starting between 0.5 and 15 t with growth between −20% and +100% (ceiling/floor test): r 0.44, Spearman 0.52. Laos (+358%), Cambodia (+254%) and the Central African Republic (+193%), all from small bases, are in the statistics but off the chart. A link, not a cause (progrss calculation). The data does not say why Estonia's emissions fell (cause not drawn). Of the 142 countries whose economies grew, 67 cut fossil CO2 per person (progrss calculation).
