The dataset contains 17 records after repeated placeholder values are removed. The estimated total is 21,366,289 tonnes of carbon dioxide for 2023.
These are Climate TRACE modelled estimates for 2023. They are not verified declarations, current emissions, tax liabilities or CBAM liabilities.
Some records may represent facility clusters. Confirm the facility, operator, installation boundary, sector and reporting period before use.

Use measured surface area, temperature and operating hours to calculate heat loss from boilers, kilns, heat exchangers, valves and pipework. Inzonex supplies removable modular insulation for equipment that requires maintenance access.
Do not add a calculated reduction to an emissions report until the reporting boundary, factor, implementation date and verification method have been approved.
