City Inventory Reporting and Information System

The City Inventory Reporting and Information System (CIRIS) is an accessible, easy-to-use and flexible Excel-based tool for managing and reporting city greenhouse gas inventory data. Based on the Global Protocol for Community-scale Greenhouse Gas Emission Inventories (GPC) standard, the tool facilitates transparent calculation and reporting of emissions for all sectors. The tool should be used in conjunction with the GPC, available at ghg protocol.org. The tool includes five calculators to facilitate calculation of emissions from typically challenging sources: 

• Fugitive losses from gas distribution
• Solid waste landfill
• Biological treatment of waste
• Waste incineration
• Wastewater
