Opra: UK Environmental Risk Scores for Installations and Waste Operations, 2014-2017

Opra (Operational Risk Appraisals) scores categorize the environmental risk of UK industrial installations and waste operations. The scheme assessed risk based on Complexity, Emissions, Location, Operator Performance, and Compliance, each graded A-E (or A-F for Compliance). The Environment Agency published full profiles from 2014 to 2017, though the scheme was withdrawn after 2017.

Use Cases

• Analyze trends in environmental compliance ratings based on the annual compliance scores.
• Compare risk profiles across different industrial sectors based on the five assessed attributes.
• Model total environmental risk scores based on the summation of Complexity, Emissions, Location, Operator Performance, and Compliance.
• Assess the relationship between operator performance scores and compliance outcomes.

Strengths

• Risk scores are based on five distinct, clearly defined attributes (Complexity, Emissions, Location, Operator Performance, Compliance).
• Data covers a defined four-year period (2014-2017) for full profiles.
• Data originates from the authoritative UK Environment Agency.

Limitations

• The Opra scheme was withdrawn in 2017, limiting data freshness for current analysis.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
