Insider Policy Change

What are the key techniques of insider policy change? When is insider policy change effective in influencing policy? What does the academic literature on policy change suggest is important to effective work? In this document, we address these questions and present our overall take on the use of insider techniques to influence US national climate policy. This review of the literature forms the basis of our work reviewing and recommending insider policy change organizations.

In Giving Green’s document How We Determined Our 2020 Research Priorities, we identified insider advocacy as one of our priority research areas for 2020. In this document, we summarize the state of evidence on insider advocacy and its promise as a method for working towards policy change that dramatically reduces the concentration of greenhouse gases in the atmosphere.

Advocacy refers to engagement in the legislative or regulatory process in order to shape priorities and influence specific pieces of legislation or regulation [1]. In this document, we provide an overview of insider advocacy, in which “insiders” with connections and experience in the policymaking process seek to influence legislators or consequential regulators. Insider advocates use techniques including:

  • One-on-one lobbying and meetings with decision-makers
  • Engagement with policymakers through seminars and events focused on policy issues
  • Direct policy support through the creation or editing of policy proposals and draft legislation
  • Policy research and dissemination focused on providing an intellectual basis and talking points to support the creation of policy.

Some evidence suggests that insider advocacy can be a highly effective strategy to influence the shape and success or failure of legislation and regulation, including climate legislation aimed at reducing the concentration of atmospheric greenhouse gases (Meng & Rode, 2019). However, each story of successful insider advocacy is matched by many comparable stories of failure (or success of the opposing side). The success of insider advocacy efforts is highly dependent on a number of contextual factors impacting the policy process. These include:

  • The policy status quo
  • Interest group organization and funding
  • Political conditions and the positions held by crucial decision-makers or median legislators
  • The tactics and sophistication of opposed groups

(See Baumgartner et al., 2009, for a useful and detailed overview of how these factors influence advocacy efforts). Effective insider advocacy organizations are those who understand these context factors well, exercise superior judgement and skill in constructing an advocacy strategy appropriate to their context, know their allies and have the right relationships with decision-makers to facilitate a given goal, and are able to adapt to the constantly shifting demands of the policy environment surrounding their goal.

Based on the ubiquity of insider advocacy in shaping legislation and regulation across all policy domains along with evidence that insider advocacy can determine the success or failure of climate legislation (discussed below in greater detail), we believe that insider advocacy is an important part of shaping climate-change legislation to reduce the concentration of atmospheric greenhouse gases. This is especially true since insider advocacy is an established and ubiquitous part of the policy creation process, and so any legislation eventually brought to a vote will necessarily reflect the work of insider advocates and experts. Insider advocacy efforts, when successful, have a high maximum potential to influence policy. However, insider advocacy overall has a moderate to low probability of achieving success. In addition, insider advocacy is inherently difficult to evaluate definitively given the context-dependent nature of insider advocacy work and the often diffuse nature of inputs to legislation from specific groups advocating for the same goal.

1 Regulation may often form the bulk of important rule-making around climate, and is an important channel for lobbying and other advocacy activities; Nelson & Yackee, 2012.
