Methodology

How the Climate Report Card Works

Each country receives a score based on 9 indicators across 5 climate domains. Scores are normalized against all countries with available data, so grades reflect relative global performance rather than absolute thresholds.

Scoring Formula

For each indicator:

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

Inverse indicators (lower = better):

score = 100 − normalized

Domain score (weighted average of its indicators):

domain_score = Σ (indicator_score × weight) ÷ Σ weight

Total score:

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

Countries missing more than 2 of 5 domains are excluded from scoring. Domain scores are re-weighted to sum to 1.0 when a domain is missing.

Grade Thresholds

A+

90–100 points

Climate leader — top global performance across most domains

A

80–89 points

Strong performer — well above average on most indicators

B+

70–79 points

Good progress — above average, some areas for improvement

B

60–69 points

Moderate action — meeting international averages

C+

50–59 points

Below average — meaningful gaps in several domains

C

40–49 points

Significant gaps — lagging on most climate indicators

D

25–39 points

Low performance — urgent improvement needed

F

0–24 points

Critical — among the worst performers globally

Limitations

  • Relative scoring: Grades measure performance relative to other countries, not against a climate-safe absolute benchmark.
  • Data gaps: Countries with missing indicators are penalized through domain exclusion, which may understate scores for less-monitored nations.
  • Structural factors: Cold climates, landlocked geography, and development stage affect energy use in ways the score does not fully adjust for.
  • Policy lag: Many indicators reflect outcomes from policies enacted years earlier, not current commitments.

Primary Data Sources

  • World Bank / Climate Watch:CO₂ per capita (EN.GHG.CO2.PC.CE.AR5), GDP per capita
  • Ember Climate:Renewable electricity %, fossil %, grid carbon intensity
  • Our World in Data / Global Carbon Project:Cumulative CO₂, global share, temperature attribution
  • Notre Dame Global Adaptation Initiative (ND-GAIN):Country readiness and vulnerability indices
