LEGGI 2012: London Energy and Greenhouse Gas Inventory

40.75 MtCO2e of greenhouse gas emissions were estimated for London in 2012, representing a 10% reduction from 1990 levels. The Greater London Authority produces this annual inventory to measure progress against the Mayor's Climate Change Mitigation and Energy Strategy. It estimates energy consumption and CO2 emissions from Homes, Workplaces, and Transport within Greater London.

Use Cases

• Tracking progress against climate targets based on annual emissions estimates.
• Analyzing sectoral contributions (Homes, Workplaces, Transport) to total city emissions.
• Modeling the impact of factors like cold winters or grid intensity changes on emissions trends.
• Benchmarking London's emissions performance against other urban areas.

Strengths

• Provides specific emissions figures, such as 40.75 MtCO2e for 2012 and a 19% reduction since the 2000 peak.
• Integrates data from authoritative sources like the Department of Energy and Climate Change and the London Atmospheric Emissions Inventory.
• Produced annually by the Greater London Authority for official policy monitoring.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The 2012 data is described as an interim version pending final confirmation.
