Regulatory Context

Where Modelling Is Required

Environmental Clearances

MoEFCC (India), Environment Agency (UK), EPA (US), and MME (Qatar) all require dispersion and impact modelling as part of EIA submissions.

Industrial Permitting

CPCB/SPCB consent applications, IPC permits (UK), and AQMD permits (US) require AERMOD or equivalent dispersion studies.

Litigation Support

Expert witness modelling for environmental disputes — contamination plume tracking, noise boundary disputes, and air quality exceedance analysis.

Climate Risk Assessment

Flood modelling, sea-level rise projection, and heat island analysis to support TCFD disclosures and physical risk quantification.
