Frequently asked questions
- What do the quarterly UK greenhouse gas emissions data measure?
- The table measures quarterly UK greenhouse gas and carbon dioxide emissions across all sources and excluding consumer expenditure, reported in thousand tonnes CO2e and thousand tonnes.
- How far back does the UK quarterly emissions dataset go?
- Quarterly greenhouse gas and carbon dioxide emissions statistics from the Office for National Statistics begin in 1999, providing both seasonally adjusted and not seasonally adjusted series.
- What does a residence basis mean for UK emissions statistics?
- A residence basis measures emissions generated by UK residents and UK-registered businesses regardless of location, including fuel used abroad by UK-operated ships and aircraft.
- What emissions intensity indicators are included in this UK table?
- The table features greenhouse gas emissions per unit of output, carbon dioxide emissions per unit of output, and greenhouse gas emissions per person, alongside gross value added per 1,000 people.
