Web-Enabled Emission Inventory Tool

The better way to automate emissions reporting


For most companies required to report their emissions, the process of collecting, managing, and reporting is fragmented, time-consuming, and needlessly expensive. Data are collected on spreadsheets that are scattered across the organization, harmonizing is confusing, and QA is laborious. Valuable staff resources are tied up with annual reporting requirements, year after year. In addition, the regulatory reporting environment keeps changing.

RWDI's Web-Enabled Emissions Inventory Tool (WEIT) is here to help. WEIT's clean interface and searchable contents lets you find information in a couple of mouse clicks. The reporting engine generates easy-to-read documents suitable for regulatory requirements. With tie-ins to atmospheric, noise and other models, WEIT helps determine where your emissions will end up. WEIT's integrated calculators can determine emission rates when measured data are not available. And because WEIT is web-based, it can be accessed anywhere, at anytime! 


WEIT is a tool for any organization that wants to simplify the task of collecting and managing its emissions data. Whether a university with laboratory fume hoods, a factory with ventilation stacks, a quarry fleet disturbing surface dust, or a large company with multiple facilities throughout the world, WEIT makes emissions data management clear and easy.

WEIT can help with

  • regulatory reporting;

  • year-over-year emission comparison;

  • alternate-scenario analysis;

  • NPRI/GHG data collection and reporting; and,

  • interfaces with common dispersion models (AERMOD, CALPUFF).


WEIT features

  • an intuitive, web-based interface to enter and modify operation, facility, source, and emission data;

  • powerful import/export capabilities to allow fast bulk loading and initialization of the system;

  • industry-standard calculators (AP-42, Ontario Ministry of the Environment, etc.) that determine emission rates based on commonly-known process parameters;

  • report generators and GIS exporters that output emission data in standard formats;

  • attachment of arbitrary files like images, PDFs, spreadsheets, etc. to one or more sources and/or facilities;

  • noise module that allows parallel tracking of sound sources;

  • interfaces with atmospheric dispersion models (e.g. CALPUFF, AERMOD);

  • multi-year and "Scenario" concepts that capture ongoing, alternative, or hypothetical operating conditions; and,

  • powerful auditing capabilities that track changes to data and provide a comprehensive audit trail.
