SBW22 - Sustainability Beyond Buildings: Scope 3 and Zero Carbon

Sustainable Building Week San Diego 2022

Wednesday, April 6th | 9am - 10am | Zoom


Moving from Planning to Action in Multinational Enterprises & Large-Scale Organizations

Sustainability planning is only the first step on a long journey of transformation. After your organization has inventoried its carbon footprint, conducted a materiality assessment, or simply hired a sustainability director, what opportunities and challenges will you face as you move into
action -- especially within complex, large-scale organizations with numerous stakeholders?

For businesses big and small looking to understand how to address their supply chain and scope 3 emissions, this session is designed to orient you to lessons learned at Brookfield Properties, and MasterCard as they looked beyond their buildings to address their zero carbon goals.

Facilitated by Brightworks Sustainability, a leading practitioner in corporate sustainability since its founding in 2001, this session will leave you with insights and ideas to move measuring and understanding your environmental impacts to making strategic change.

Panel Discussion Agenda:  

  1. Structuring your stakeholder alignment process.
  2. Measuring your starting point.
  3. Developing an effective execution strategy.
  4. Transformation, activism and global change about the importance of building electrification and zero net energy throughout the state.

Learning Objectives: 

  • Formulate the materiality of your scope 3 emissions from the case studies presented
  • Adapt lessons learned from the case studies to your own example
  • Plan how best to manage the discovery process in your example
  • Recommend meaningful improvement opportunities/Maintenance Managers
