1.Visualizing Regional Data Gaps with Heatmaps
Heatmap Analysis · 2026
An ESG Greenwashing Analyst generated a heatmap to visualize the annual gap between production-based and consumption-based CO₂ emissions across various countries, measured in megatonnes (Mt). The visualization spans from 1990 to roughly 2023, highlighting nations like the United States with a massive positive gap peaking around 2005, and Ukraine showing negative gaps in the 1990s. By plotting historical data ordered by average gap (ranging from -400 to 400 Mt), the analyst bypassed the need to manually write Python scripts to handle missing consumption values. This visualization technique is highly effective for identifying regional discrepancies in multiple location inventory management.
