How this service works
Calculates waste-treatment emissions by route from published treatment factors. Missing facts are returned as null and named in unavailable_fields where applicable. Derived values disclose their method; source-backed values disclose source, time window and age. This is neither legal advice nor customs advice.
Output
Returns computed CO2-equivalent emissions for each treatment line item, a total, disclosure of the calculation method used, source citation with publication date and data age, and a list of unavailable_fields for any inputs where data could not be resolved. Derived values indicate their derivation method; source-backed values indicate their provenance.
Example use cases
Scope 3 waste emissions for ESG report
“I need to calculate the GHG emissions from our Q3 waste disposal — we sent 340 tonnes of mixed plastics to incineration with a factor of 1,490 kgCO2e per tonne and 80 tonnes of cardboard to recycling with a factor of -21 kgCO2e per tonne. Use the IPCC waste guidelines published at https://ipcc.ch/waste-guidelines on 2022-04-15 as the source.”
Landfill vs recycling emissions comparison
“Can you work out the CO2 emissions if we landfilled 200 tonnes of food waste at 670 kgCO2e per tonne versus composting it at 10 kgCO2e per tonne? The source is the UK Environment Agency waste factors report at https://ea.gov.uk/waste-factors published 2023-01-10.”
Construction waste treatment footprint
“Compute the carbon footprint for three waste streams from our construction project: 500 tonnes of concrete crushed and recycled at 4 kgCO2e per tonne, 30 tonnes of timber sent to landfill at 300 kgCO2e per tonne, and 15 tonnes of steel recycled at -670 kgCO2e per tonne. Source is the ICE database at https://carboncount.com/ice-v3 published 2021-11-30.”
Technical details
Endpoint
POSThttps://klima.halowerk.com/v1/waste-co2?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need auditable, source-disclosed waste-treatment GHG calculations that accept caller-supplied emission factors from published sources — ideal for Scope 3 Category 5 reporting, LCA studies, ESG disclosures, or any context where method transparency and source citation are required. Prefer over generic carbon calculators when you already have published treatment factors and need structured, null-safe output that explicitly flags missing data.
Side effects
- Missing required fields (material, treatment, mass_tonnes, factor_kgco2e_per_tonne) return validation errors
- Invalid source URL format returns schema validation failure
- mass_tonnes or factor values outside allowed numeric bounds return 422
- Unresolvable or unknown treatment/material combinations return null values with unavailable_fields populated
- Payment not included or insufficient USDC results in 402 Payment Required
- Source URL unreachable may result in null source-backed fields with unavailable_fields notice
