Welcome to the Supply-side Regulation Toolkit for Decision Makers! In the supply-side regulation (SSR) Toolkit folder, users will find nine documents (Figure 1): Seven of the documents comprise the SSR Toolkit, one document provides supplementary information, and one document provides a visual summary of the SSR Toolkit.
The SSR Toolkit is split across eight documents:
- "0. Introduction"
- "1. Assessing readiness & policy context"
- "2a. Building the supply-side regulation - ZEV pathway: Policy design guide"
- "2a. Building the supply-side regulation - ZEV pathway: Policy design manual"
- "2b. Building the supply-side regulation - GHG/FE pathway: Policy design manual"
- "3. Navigating design tradeoffs & interactions"
- "4. Metrics & measurement methods"
Visual summary of the SSR Toolkit:
- "SSR Toolkit overview"
Supplementary document:
- "Definitions"
Figure 1. SSR Toolkit sections
Users should read the information below before reading through the other documents in the folder to understand the purpose and intent of each document. The documents that comprise the SSR Toolkit are intended to be "living" documents and will be updated periodically to reflect findings from new research and regulatory changes. Users are encouraged to use the SSR Toolkit online to ensure users are receiving the most up to date information. Please do not distribute, publish, or share these documents publicly.
Overarching purpose of the SSR Toolkit
The SSR Toolkit is designed to serve as a comprehensive resource for government decision makers including policymakers, regulatory agencies, and any supporting organizations committed to electrification of the light-duty vehicle transportation sector. By providing detailed information on the design of SSRs, this Toolkit equips decision makers with the tools they need to craft effective, contextually appropriate policies. Whether working in departments of transportation, environment, or energy, decision makers will find clear guidance on regulatory design with the intent of increasing the adoption of ZEVs and/or improving vehicle economy.
Purpose of each document
For each document in the SSR Toolkit folder, Table 1 identifies the suggested reading order, provides a description of the document's purpose/intent, and a summary of the information contained in each document. Each of the documents that comprise the SSR Toolkit are designed to be modular, stand-alone documents. Toolkit users are encouraged to read through all documents to gain a comprehensive picture for building a SSR; however, this approach is not required and users can opt to read only the sections most pertinent to their stage of SSR building.
Throughout most of the documents listed below, hyperlinks are used to link to other sections within the same document, other documents contained within the SSR Toolkit folder, or external links to government websites or academic resources. Toolkit users are encouraged to use these additional resources.
Table 1. SSR Toolkit folder document summary
| Document | Reading order | Description |
|---|---|---|
| 0. Introduction | 1 | This document introduces users to the SSR Toolkit by:
Users should read this document first as it provides important context. |
| 1. Assessing readiness & policy context | 2 | This document guides users through an information gathering exercise so users have a better understanding of the following in their region:
This section also provides guidance on the feasibility of implementing a SSR given the regional context, and the implications of regional attributes on policy design. Users should read this document (and conduct the information gathering exercise) before building their SSR to provide them with the information needed to create a context dependent SSR. |
| 2a. Building the supply-side regulation - ZEV pathway: Policy design guide | 3a* | This document provides users with ZEV sales standard policy design options for each design element. Options are presented from most simple to least simple (most complex) so that users can select the SSR design that best suits their resource capabilities and context. Users should read this document if they have 1) completed the information gathering exercise outlined in "1. Assessing readiness & policy context" and 2) have decided they would like to pursue a ZEV sales standard or are undecided about which SSR to choose. |
| 2a. Building the supply-side regulation - ZEV pathway: Policy design manual | 3a* | This document provides a comprehensive (but not exhaustive) exploration of policy design elements including a summary of the design element, examples of how existing SSRs have approached the design element, a discussion on the pros and cons of different design approaches, and notes to the policymaker on important key decisions and best practices. This document is intended to serve as a supporting document to the Policy design guide above. Users should read this document to gain clarity and further information on the information presented in the Policy design guide. |
| 2b. Building the supply-side regulation - GHG/FE pathway: Policy design manual** | 3b* | This document provides a comprehensive (but not exhaustive) exploration of policy design elements including a summary of the design element, examples of how existing SSRs have approached the design element, a discussion on the pros and cons of different design approaches, and notes to the policymaker on important key decisions and best practices. This document is intended to serve as a supporting document to the Policy design guide above. Users should read this document if they have 1) completed the information gathering exercise outlined in "1. Assessing readiness & policy context" and 2) have decided they would like to pursue a GHG or FE standard or are undecided about which SSR to choose. |
| 3. Navigating design tradeoffs & interactions | 4 | This document discusses policy design tradeoffs and design element interactions to provide users with an understanding of the consequences of different policy designs. It takes a macro look at how policy design decisions may impact the outcome of the policy once implemented. Users should read this document as they are building their SSR so that they understand the tradeoffs of SSR design and the interactions of design elements. |
| 4. Metrics & measurement methods | 5 | This document details different approaches to measuring SSR metrics to help users choose the metrics that fit best with their region's context. Users should read this document as they are building their SSR so that they can select the metrics most relevant to their context for inclusion in the regulation. |
| SSR Toolkit overview | (optional) | This document provides a more visual overview of the SSR Toolkit. Users can provide this overview to colleagues who are not directly involved in the SSR building process but require a broad understanding of how the SSR Toolkit works. Users can read this to gain an overview of the SSR Toolkit but this should not be a substitute for the detailed SSR Toolkit sections above. |
| Definitions | (optional) | This document defines common acronyms and terms used throughout the SSR Toolkit. Users can use this document to look up common acronyms and terms used throughout the SSR Toolkit. |
Footnotes
*Note that if users have already decided on the SSR type for implementation in their region, they only need to read the documentation relevant to that pathway. If users are undecided, it is recommended that they read documentation for both pathways to better understand the options available to them.
**The GHG/FE standard does not have an accompanying policy design guide, just the policy design manual.
