Our Sustainability Services

Greenhouse Gas (GHG) Inventories

Looking to measure your organization's GHG emissions, but aren't sure where to start? We specialize in GHG inventory development and carbon quantification. As CSA certified GHG Inventory Quantifiers (GHG-IQ), our personnel are skilled in compiling and calculating GHG emissions at both the organizational and facility levels. We follow internationally recognized standards and protocols including the Greenhouse Gas (GHG) Protocol, World Resources Institute (WRI), and Intergovernmental Panel on Climate Change (IPCC). 


In need of sustainability reports showing your company's carbon footprint and GHG emissions reductions over time? Perhaps your clients want to know what their indirect emissions are from using your products or services? We provide monthly, quarterly, annual and event-specific sustainability and emissions reporting to help your organization document and disclose GHG emissions month-over-month, quarter-over-quarter and year-over-year to track environmental performance.
