How this service works
Returns carbon dioxide emissions for one or more countries on three bases at once: per inhabitant, per unit of purchasing-power-adjusted output, and in absolute megatonnes, each with its own period and its trend over the requested window. Keeping the three apart is the point. Per capita answers how heavily a person there burdens the climate; per unit of output answers how efficiently value is produced; absolute answers what actually reaches the atmosphere.
Output
Returns a structured response containing, for each requested country, CO2 emissions on three distinct bases: (1) per capita (tonnes per person), (2) per unit of PPP-adjusted GDP output (carbon intensity of the economy), and (3) absolute emissions in megatonnes — each accompanied by the data period covered and a trend indicator over the requested window.
Example use cases
Sustainability report country comparison
“I'm preparing a sustainability report and need CO2 data for the US, China, Germany, and India — give me per capita emissions, carbon intensity per unit of GDP, and total megatonnes for each, with trends over the past decade.”
Investment ESG due diligence screen
“For my ESG screening, can you pull carbon intensity data for South Korea and Taiwan — I need all three bases (per person, per unit of economic output, and absolute) with trends over the last five years so I can compare how efficiently they're decarbonizing?”
Climate policy effectiveness analysis
“Show me how Brazil's carbon emissions have trended over the past 15 years on all three measures — per capita, per PPP-adjusted GDP, and total megatonnes — so I can assess whether their climate policies are having any effect.”
Technical details
Endpoint
POSThttps://stat.halowerk.com/v1/carbon-intensityWhen to prefer
Choose this endpoint when you need all three CO2 measurement bases simultaneously for one or more countries, especially when the distinction between per-capita burden, economic carbon efficiency, and absolute atmospheric contribution all matter. It is the right choice for sustainability benchmarking, ESG analysis, climate policy research, or any scenario requiring decomposed carbon accounting rather than a single aggregate figure.
Side effects
- Unknown or unsupported country code returns an error or empty result
- Requested time window extends beyond available data coverage
- Data unavailable for a specific country-metric combination returns partial results or null
- Malformed POST body causes a 400 validation error
- Payment not settled triggers a 402 payment required response
