Key Insights from the Carbon-Intensity vs. GDP per Capita file

1. What is in the file?

  • 294 yearly observations (2003-2023) covering 14 countries on 7 continents.
  • For every country–year we have:
    • carbon_intensity (t CO₂ per US-$ of GDP, PPP-adjusted)
    • gdp_ppp (GDP per capita, constant 2017 US-$)
    • population and simple ISO / continent descriptors.

2. Relationship between prosperity and carbon intensity

  • The overall Pearson correlation between the two variables is –0.17 – a weak negative link: richer economies tend to emit less CO₂ per dollar of output, but the relationship is far from uniform.
  • When we break it down by continent the picture becomes sharper:
Continentρ(CI, GDP)
Europe–0.95
North America–0.83
Caribbean–0.75
Asia+0.26
Oceania+0.50
South America+0.73
Africa+0.95
→ Europe & North-America show a strong decoupling: as GDP grows, carbon intensity falls steeply. In contrast, African countries in this sample still get more carbon-intensive as they grow.
(The interactive scatter plot above lets you hover a point and see the country & year, with an OLS trend-line for the global sample.)

3. Global evolution of carbon intensity

![Global Trend](The second plot)
  • Simple (unweighted) average carbon intensity fell by ~30 % from 0.20 t CO₂/
    $ to ~0.14 over 2003-23.
  • A population-weighted average declines more slowly (≈20 %) – indicating that larger, often still-developing, economies make the global reduction harder.

4. Regional trajectories (3rd plot)

  • Europe keeps a clear downward trajectory, leading the decline.
  • Africa and Asia remain persistently high; Africa even shows a slight increase in the last decade.
  • Oceania and South America lie in the middle, trending downward but at a slower pace.

5. 2023 snapshot – leaders & laggards

  • Lowest carbon intensity (best performers)
    1. Nigeria – 0.10
    2. Germany – 0.11
    3. Dominican Rep. – 0.12
    4. Brazil – 0.12
    5. New Zealand – 0.14
  • Highest carbon intensity (worst performers)
    1. South Africa – 0.46
    2. China – 0.41
    3. Canada – 0.25
    4. Jamaica – 0.23
    5. Australia – 0.23

6. Take-aways

  1. Decoupling is possible: advanced economies are cutting emissions per unit of output while continuing to grow.
  2. Emerging economies matter: their large populations slow the global average decline.
  3. Policy implications: technology transfer & clean-energy finance to fast-growing regions (Africa, Asia) could accelerate global progress.
  4. Data gaps: only 14 countries are represented – expanding the dataset would give a more complete picture.
Would you like to dive deeper? You could:
  • Compare individual country time-series.
  • Look at per-capita emissions alongside intensity.
  • Test whether the trend-line slopes differ significantly between continents.

Key Insights from the Carbon Intensity vs. GDP per Capita dataset (2003-2023)

What’s in the file?

• 294 country-year observations for 14 countries on 7 continents.
• Variables: carbon_intensity (t CO₂ per 2017-$ of GDP), gdp_ppp (GDP per capita), population, plus identifiers.

1 ) Prosperity vs. Carbon Intensity

• Overall Pearson correlation: –0.17 (weak negative)
• By continent:
• Europe –0.95 • North America –0.83 • Caribbean –0.75 • Asia +0.26 • Oceania +0.50 • South America +0.73 • Africa +0.95
→ Europe & North America show strong decoupling; Africa shows the reverse.

2 ) Global trend

• Unweighted global average carbon intensity fell ≈30 % (0.20 → 0.14) over 2003-23.
• Population-weighted average fell ≈20 %, indicating slower progress where most people live.

3 ) Regional trajectories

• Europe declines fastest.
• Africa is flat-to-rising; Asia remains high but slowly declines.

4 ) 2023 Leaders & Laggards

• Lowest CI: Nigeria (0.10), Germany, Dominican Rep., Brazil, New Zealand.
• Highest CI: South Africa (0.46), China (0.41), Canada, Jamaica, Australia.

5 ) Take-aways

  1. Decoupling is occurring in advanced economies.
  2. Emerging-economy progress is crucial for global averages.
  3. Policy: support clean-energy growth in Africa & Asia.
  4. Expand the sample to more countries for a fuller view.
