Supporting global efforts to reduce greenhouse and polluting gas emissions, the EU’s Industrial Emissions Directive introduces new limits and reporting rules. Europe’s gas plant operators are expected to identify and measure leaks, but tougher limits require greater measurement accuracy beyond that of current authorised methods. Advanced optical measurement techniques exist but these need robust performance evaluation and protocols for use before consideration as methods for demonstrating compliance with the Directive.
