Zartner's research focuses on international and comparative law and its internalization at the intersection of human rights and environmental justice. Overarching themes in Zartner's writings include: the role of legal culture and legal institutions in shaping approaches to law and policy in the areas of human rights and environmental justice; innovative and multilevel activism to create better environmental law and policy, particularly using the courts and in the face of non-supportive governments; shifting ideas of the human-nature relationship to promote more sustainable environmental policy; corporate social responsibility and the role of non-state/sub-state actors; and recognizing and addressing vicarious trauma and compassion fatigue in those working in social justice fields. Zartner has served as an accredited representative at various UN meetings, including the Expert Mechanism on the Rights of Indigenous Peoples and the Human Rights Council in Geneva and the Committee on the Status of Women in New York.

Argues that the degree to which states accept and comply with international legal norms is rooted in a country's domestic legal tradition. Looks specifically at state policy towards international human rights and environmental law. Disaggregates the concept of legal tradition and examines how the individual cultural and institutional characteristics present within a state's domestic legal tradition facilitate or hinder the internalization of international law and, subsequently, shape state policy.
Examines the assumption that outside assistance and courts are essential for addressing issues in the aftermath of humanitarian crisis in the context of Uganda. Considers how the state's legal tradition shapes societal perceptions about justice, peace, and appropriate actions in the aftermath of a crisis. Considers what local communities, steeped in their own histories and legal traditions, believe are the best solutions in post-conflict societies and argues that traditional legal mechanisms such as customary law and religious law should be considered in addition to Western-style codes and courts in order to have a more effective system of transitional justice.
Examines the root causes of environmental degradation and impacts of climate change that are causing increased migration of environmentally displaced persons. Argues for a new international convention that provides protections for environmentally displaced persons and creates affirmative obligations for states to work toward addressing climate change and preventing environmental displacement in the future.
