How the Climate Report Card Works

Each country receives a score based on 9 indicators across 5 climate domains, normalized against all countries with available data.

Normalized score:

normalized = (value − min) ÷ (max − min) × 100

Inverse indicators (lower = better):

score = 100 − normalized

Total score:

total = 0.30×Emissions + 0.25×Energy + 0.15×Economy + 0.15×Responsibility + 0.15×Resilience
