Responsible Corporate Adapatation

UN Global Compact

Four Twenty Seven was the lead author on the latest Caring for Climate report on responsible corporate adaptation, developed in cooperation with the UN Global Compact, UNFCC and UNEP, and their partners.

With this new publication, Caring for Climate compiles and showcases a wide range of corporate and public-private adaptation practices in different sectors and regions in order to:

  • Raise awareness about the benefits of implementing climate risk assessments, and inform companies about subsequent adaptation activities that can be taken to mitigate those risks.
  • Inspire other companies, regardless of size and geography, to implement private adaptation strategies and activities that also contribute to increasing societal resilience and meeting the SDGs.
  • Highlight opportunities for policymakers to address the barriers that may hinder corporate adaptation activities.

Training the Workforce of the 21st Century

Association of Climate Change Officers (ACCO)

Climate change and sustainability professionals help their organizations to adapt and thrive in a world of climate uncertainty, and guide their organizations toward strategic decisions that are simultaneously beneficial for the organization as well as the climate.

The Climate Change Officers ™ Certification was developed by ACCO and its partners to ensure that these professionals are equipped with best-in-class tools and concepts. Four Twenty Seven helped develop and delivers two certifications courses:

  • Supply Chain-101: Introduction to Assessing Climate Related Risks in the Supply Chain
  • Enterprise-201: Analyzing & Quantifying Climate Risk, Assessing Materiality & Disclosing Climate Risk

Our original materials articulate key concepts in economics and climate science to empower course participants to asses climate risks and develop an effective climate adaptation strategy for their organization.


Sizing Up Climate Resilience in the Bay Area

Bay Area Regional Collaborative (formerly JPC)

Measuring progress towards resilience at the community level is challenging at the best of times, and in the San Francisco Bay Area, this problem is compounded by the number of jurisdictions, agencies and organizations that address climate adaptation from different angles and at different scales.

In her role at BARC, Aleka worked with climate staff at SPUR to co-author Sizing Up Climate Resilience in the Bay Area. This white paper provides an assessment of Bay Area efforts to measure and build climate resilience, a recommended list of resilience indicators and a summary of best practices for practitioners working to measure adaptation efforts at multiple scales. The project was funded by the San Francisco Foundation.
