The relationship between humanity and the environment is a defining element of the twenty-first century. From climate change to biodiversity loss, environmental concerns increasingly shape political debate, economic policy, and daily life. As a result, environmental law sits at the center of this connection, evolving into a critical legal framework that shapes policy, business practices, and international cooperation.
However, many of us may find ourselves asking: What exactly is environmental law? The Legal Information Institute defines this term as laws and requirements, on the Federal, State, and local level, that are related to "protection of human health, natural and cultural resources, or the environment." While accurate, this definition only encapsulates the very surface of this sector. In practice, environmental law is an expansive and rapidly developing field that influences nearly every aspect of modern society. Virtually every major industry today, spanning manufacturing, technology, transportation, must operate within environmental regulations.
The field itself offers remarkably diverse professional choices. Certain environmental lawyers appear before federal, state, or local courts, often representing government agencies or corporate structures, enforcing laws or challenging agency action. However, litigation is only a sliver of the skillset required. Environmental attorneys also draft legislation, advise policymakers, support business and property transactions, and consult with industry to achieve compliance with environmental laws.
Modern environmental law is built on a foundation of legislation from the past forty years. Landmark federal statutes such as the National Environmental Policy Act of 1970, the Clean Air Act of 1963, the Clean Water Act of 1972, and the Endangered Species Act of 1973, established the federal government's authority to regulate pollution, protect our ecosystems, and hold industry and corporations accountable. The National Environmental Policy Act of 1970, specifically, requires all federal agencies to integrate environmental considerations into their decision-making processes; in practice, agencies must draft detailed analyses of potential environmental damage and alternatives for any major federal action, such as issuing permits or funding infrastructure.
Furthermore, these statutes fueled the expansion of authority of agencies such as the United States Environmental Protection Agency (EPA), which plays a central role in enforcement and policymaking today. Administrative regulations, agency decisions, and policy at the federal, state, and local levels are crucial to the work of environmental attorneys in order to achieve the adherence of these statutes. For instance, the Clean Water Act requires permits for the discharge of material into wetlands or other protected areas. As a result, environmental attorneys may assist attorneys in obtaining said permit, advise businesses on compliance requirements, or challenge/defend permit approvals.
What was once perceived as a specialized area of law has now become central to conversations about the future of humanity and the environment.
Over time, environmental law has developed alongside scientific advancement and growing public awareness surrounding environmental issues. What was once perceived as a specialized area of law has now become central to conversations about the future of humanity and the environment. Climate change, environmental injustice, and the push towards renewable energy have contributed to the rise of environmental concerns into the forefront of public policy and legal practice. As the impact of climate change grows incredibly visible through rising global temperatures, devastating wildfires, extreme hurricanes, and sea-level rise, governments and agencies face immense pressure to push legal and regulatory responses and compliance measures.
As these challenges continue to intensify, the demand for environmental attorneys, advocates, and policymakers has grown. Corporations are expected to adopt sustainable practices, communities rely on legal protections, and governments and politicians face pressure to strengthen environmental regulations. To illustrate, California has enacted a variety of aggressive climate policies, including what is widely known as the 2035 zero-emission vehicle mandate, requiring all new passenger vehicles sold in California be zero-emission vehicles (ZEVs); this is designed to reduce state-wide greenhouse gas emissions from the transportation sector.
For the reasons mentioned in this article, environmental law matters now more than ever. It has become one of the primary legal frameworks to address some of the most urgent and complex concerns of the modern era.
