Emissions, GHG and life cycle assessment
We assess emissions from thermal processes and the environmental impacts of operating alternatives. Work may include greenhouse-gas inventories, life cycle assessment and pollutant formation or dispersion studies.
When to involve our team
We start with your plant’s problem to define the technical scope.
- Emission sources and activity data need to be identified and organized.
- A fuel switch must be assessed beyond stack emissions.
- Production routes need to be compared per unit of product.
- The plant wants to assess process changes and emission-control systems.
What we deliver
Explicit assumptions, traceable calculations and recommendations linked to plant operation.
Scope and inventory
Definition of boundaries, sources, data and emission factors, with traceable assumptions.
Environmental comparison
Scenario analysis, functional unit and relevant life-cycle stages.
Reduction priorities
Identification of dominant contributions and assessment of technical options.
