Climate Change

The Climate Change Committee fosters water sector climate expertise in the areas of mitigation (reducing GHG emissions) and adaptation (preparing for the impacts of climate change) to deliver resources, tools, and best practices to OWWA and WEAO members.

GHG Inventory Tool

The WEAO/OWWA Climate Change Committee is excited to announce the availability as of April 17, 2023 of the Greenhouse Gas Emissions Inventory Tool (GHG Inventory Tool).  The tool was based on a GHG Inventory developed by the University of Toronto under contract to Toronto Water and is now hosted and maintained by a Task Group of the Climate Change Committee.  The GHG Inventory Tool is free and transparent and was designed to be accessible to all users with inputs that utilities commonly already have on hand.  The spreadsheet tool and its accompanying user guide can be accessed in the link below.
