What is a State Attorney General?

The State Energy & Environmental Impact Center studies and supports the work of state attorneys general in defending, enforcing, and promoting strong laws and policies in the areas of climate, environmental justice, environmental protection, and clean energy. But what exactly is a state attorney general, and what do they do?

Map of the United States


Each state and territory in the United States has its own lawyer who represents both the state or territorial government and the public. These lawyers have a variety of responsibilities and powers, which include advising, defending, and bringing actions on behalf of state agencies; enforcing state laws; and serving the public’s interest. These lawyers are—you guessed it!—state attorneys general.

The role of a state attorney general is unique for a few reasons.

The primary role of an AG is to represent state agencies in court. But the powers of an AG can and often do extend beyond this role: AGs take many different actions to protect and represent the people of the state, which empowers AGs to respond nimbly as administrations change and issues evolve. The Center’s “A Role for State Attorneys General in a Just Transition” report provides an illustration of this by identifying how AG tools like enforcement, public education, and advocacy can be used to help promote a more just transition as the energy sector moves towards clean energy and away from fossil fuels.

Additionally, AG authorities vary considerably by state or territory.

Each AG has a staff that makes up the state’s Office of Attorney General—abbreviated as OAG or AGO, and sometimes called the Department of Justice (DOJ) or Department of Law (DOL). In addition to lawyers, who usually have a title of “Assistant Attorney General” (AAG), an AG’s office may also include economists, scientists, librarians, communications professionals, and other non-lawyer positions. This video by former Maine AG Jim Tierney describes the structure of an AG’s office.

Nuts & Bolts

So how do AGs get into office? This, and many other parameters of the office, vary by state. Most AGs are elected by the general public. A handful are appointed by the governor (see this paper for a deep dive on the relationship between state AGs and governors), or selected by another state body. Most AGs serve a term of 4 years, though some states’ terms are as short as 2 years. Limits on the number of terms an AG can serve also vary, with some states limiting by total terms, some by consecutive, but most not limiting the number of terms at all.

  • Attorney general is often abbreviated as “AG”
  • The plural of attorney general is “attorneys general”

AG Powers

A slightly blurred picture of the "attorney general" entry in a dictionary.

AGs have a wide variety of tools that they can use to protect and defend both the people and the state. Our AG Actions Database gives a good sampling of actions AGs have taken in the areas of climate, clean energy, and the environment.

Law Enforcement
One of the primary roles of an AG is to enforce the law. They often do this through filing lawsuits or taking other enforcement actions against companies and individuals that violate the law. Though AGs do some criminal enforcement and prosecution work, most states limit their AG’s criminal jurisdiction, so AGs typically focus on civil matters.1

Representing the Public

An AG—sometimes referred to as the “people’s lawyer”—represents the public’s interest. At the state level, they do so through affirmative actions such as participating in state administrative proceedings, providing testimony at hearings, proposing legislation, and launching investigations. They also do this federally, by engaging in rulemaking processes at federal agencies, sending letters to Congress, testifying at hearings, and more. AGs also keep the government in check, suing federal or even state agencies when they violate the law or exceed their authority, which in turn protects the public. At both levels, AGs have a fairly broad set of policy and legislative advocacy tools that can adapt to the challenges and opportunities presented by any particular circumstances.

Representing the State

AGs also represent and serve the government. They advise state agencies, represent and defend the state in court, and issue legal opinions clarifying and answering questions about state laws.

Other Powers

AGs also have a variety of soft powers that come with their position as public figures with a platform, connections, and influence. Filtering for “other” action types in our AG Actions Database gives a sense of the different ways AGs can be creative in using their powers to enforce existing laws and leverage change. To name a few examples from the climate and clean energy space, AGs have:

  • launched initiatives to bolster public participation;

  • awarded grants for environmental projects;

  • issued reports on energy market challenges;

  • launched public education campaigns on issues such as illegal idling and the dangers of asbestos;

  • set up consumer protection hotlines related to environmental disasters and misconduct;

  • sent letters to companies encouraging compliance with state environmental laws;

  • written op-eds on pressing climate and environmental justice issues;

  • created task forces on topics like extreme heat and energy justice;

  • and much more.
