How to Conduct a GHG Inventory: A Beginner's Guide

How to Conduct a GHG Inventory: A Beginner's Guide

Resources and tools

Starting a GHG inventory is essential for cities tackling climate change. Begin by assembling a team, defining the scope (direct and indirect emissions), and selecting a methodology like the GPC. Collect and verify data from sources like utility bills and traffic studies, calculate emissions, and compile a report. Use the findings to create a climate action plan and continuously monitor progress to reduce emissions effectively.
