Scope 3 is inherently challenging; there is no single, exact blueprint, and organizations must continually make decisions that balance feasibility, accuracy, compliance and scalability. Across this three-part webinar series, Sphera’s experts will provide an actionable roadmap that takes you from preparing for your first scope 3 inventory – evaluating the materiality of categories, identifying data availability, and selecting appropriate emission factor sources and methodologies – to iteratively improving accuracy over time, resulting in an inventory that’s truly representative of your operations and can effectively inform decarbonization planning and meet reporting requirements.  

In part I, we’ll explore how to calculate an initial scope 3 emissions inventory, limitations and opportunities of economic input/output data, and illustrate how software platforms can automate data collection, calculations, and reporting.  

Learn practical strategies for data organization, selecting appropriate emissions factors, and describe Sphera’s glide path to more detailed and action-oriented measurements enabling continuous improvement.   

Join us to lay a solid foundation enabling you to optimize your scope 3 strategy. 

Who is this session for:  

  • Organizations looking to voluntary disclose scope 3 
  • Organizations requiring a scope 3 assessment 
  • Any large organization based in North America that does not have significant operations in Europe/internationally 
  • Organizations that must comply with California Climate Corporate Data Accountability Act (CCDAA)
