Public ledger · last reviewed 14 Sep 2026

Not every company must log CO2. Some must. This site says which.

EU climate reporting was narrowed in 2026. Border carbon charges did the opposite: they went live. CO2 Log is a cross-regime screen for the emissions record you actually have to keep — statutory or because a customer asked.

Run the checker What a log contains

The law is narrower than the headlines

After Omnibus I, CSRD reaches EU companies only if they exceed both 1,000 employees and €450 million net turnover. That is thousands of groups, not tens of thousands.

The 2026 hook is CBAM, not a mass CSRD

From 1 January 2026, EU importers of cement, iron and steel, aluminium, fertilisers, electricity and hydrogen generally log embedded emissions above a 50-tonne threshold. The UK follows in 2027. California SB 253 is a US$1 billion corporate disclosure, not a European SME duty.

A public trend, not a company score

These lines are territorial CO2 — fossil fuels and cement, counted where they were burned or produced. They are not a GHG Protocol inventory. A company’s Scope 1–3 total is a different book. Use the indexed chart to read pace: whether a jurisdiction’s emissions rose or fell since 1990, not to score a firm against a country. See what a log contains.

World territorial CO2 Billion tonnes per year, 1990–2024
World territorial CO2, 1990 to 2024 Production-based fossil and cement CO2 for the world, rising from 22.7 Gt in 1990 to 38.6 Gt in 2024. 0 10 20 30 40 1990 1995 2000 2005 2010 2015 2020 2024 Gt

Change since 1990 Indexed, 1990 = 100. World, EU-27, Germany, UK, United States.
Territorial CO2 indexed to 1990 EU-27, Germany and the United Kingdom are well below their 1990 levels. The United States is near its 1990 level. The world total is substantially higher. 0 50 100 150 200 1990 1995 2000 2005 2010 2015 2020 2024

Five questions the checker answers

CSRD / ESRS E1

Who still files a corporate GHG inventory in the EU, and what “gross” means.

EU CBAM

Product-level embedded emissions for authorised declarants, not a company footprint.

UK CBAM

£50,000 registration test, record-keeping below it, start date 1 January 2027.

California SB 253

US$1bn + California nexus. Scope 1 and 2 in 2026; Scope 3 not this cycle. Litigation live.

Customer request

A questionnaire is not CSRD. The value-chain cap can limit what you must send.
