UL 3650 PDF

2 Scope

2.1 This Standard provides a general framework for evaluating and reporting on climate resilience and risk assessment that can be applied across several product categories to identify, assess, evaluate, and manage product vulnerabilities to climate impacts. Climate impacts in this document fall into two categories:

1. a) Acute impacts from extreme weather events and natural disasters; and

2. b) Long-term chronic impacts of change in climate patterns.

2.2 Additionally, the Standard addresses how to account for regional trends and variations, performance and design threshold with climatic loads, projected future intensity and frequency of extreme weather events, and actions to prevent, mitigate, or limit damage while enhancing a product’s climate resiliency.

2.3 This Standard includes detailed requirements on the following:

1. a) Section 5, Evaluation and Assessment Criteria

2. b) Section 6, Preparing a Product Level Climate Risk Assessment

3. c) Section 7, Assessing Climate Risks at the Product Level

4. d) Section 8, Addressing Climate Risks at the Product Level

5. e) Section 9, Monitoring, Reporting, and Verification (MRV)

2.4 This Standard does not cover climate risks associated with the product’s production process and supply chain (e.g., resource availability, transportation, or manufacturing disruptions due to climate impacts).
