Greta Thunberg: Leadership and Community Impact
Greta Thunberg has emerged as one of the most influential environmental activists of the twenty-first century. Born in Sweden in 2003, Thunberg first gained global attention in 2018 when she began protesting outside the Swedish parliament to demand stronger government actions on climate change. Her individual school strike quickly expanded into a global movement known as Fridays for Future, which encouraged students around the world to protest political inaction on climate issues. Through speeches, demonstrations, and social media advocacy, Thunberg has become a prominent figure in global environmental activism. Her leadership exists within several interconnected communities, including youth movements, environmental organizations, and international political discussions. The influence she has developed can be better understood through leadership theories present in Craig E. Johnson and Michael Z. Hackman’s Leadership: A Communication Perspective. In particular, Thunberg’s approach aligns with transformational leadership, a theory that emphasizes inspiring followers to pursue collective change and challenge existing institutions.
Chapter 3 of Johnson and Hackman’s text explores leadership approaches such as the traits and skills perspective. These approaches suggest that leadership effectiveness is influenced by both learned abilities and personal characteristics. Greta Thunberg is influenced by both learned abilities and personal characteristics. Greta Thunberg demonstrates several key leadership skills that have contributed to her global influence. One of the most significant skills she exhibits is effective communication. Leadership scholars emphasize that communication is central to the leadership process because it allows leaders to articulate their vision and motivate others to act. Thunberg’s speeches frequently emphasize the urgency of climate change and call for immediate political action. Her address at the 2019 United Nations Climate Action Summit, in which she criticized global leaders for failing to respond to climate science, demonstrated her ability to communicate a powerful and emotionally compelling message. Another leadership skill she demonstrates is strategic thinking. Thunberg;s decision to protest every Friday created a clear and repeatable action that others could easily adopt. This strategy helped transform a single protest into an international movement. Persistence is another important skill that defines her leadership. Despite criticism from political leaders, media outlets, and climate change skeptics, Thunberg has remained committed to her activism and continues to advocate for environmental reform.
In addition to these skills, Thunberg demonstrates leadership behaviors that further illustrate her leadership style. One notable behavior is her willingness to challenge existing political and economic systems that she believes contribute to environmental harm. By publicly criticizing governments and corporations, she draws attention to the policies and practices she believes must change. Another leadership behavior is her ability to mobilize followers. Through the Fridays for Future movement, millions of students have participated in climate strikes across the world. This widespread participation demonstrates her capacity to motivate individuals to engage in collective action. Thunberg also exhibits several traits that support her leadership effectiveness. Authenticity is one of her most recognizable characteristics. She communicates directly and openly about climate change, which helps establish credibility with her supporters. Courage is another defining trait, as she frequently addresses world leaders and powerful institutions despite the scrutiny she faces. Finally, determination plays a central role in her leadership. Her consistent activism over several years demonstrates a strong commitment to her beliefs and goals.
Thunberg’s leadership style can also be understood through the concept of transformational leadership discussed in Chapter 4 of Johnson and Hackman’s text. Transformational leaders inspire followers by presenting a compelling vision for change and encouraging people to pursue goals that benefit society as a whole. Thunberg frames climate change as both a scientific and moral issue that requires immediate attention. By emphasizing the long-term consequences of environmental neglect, she encourages individuals to view climate action as a collective responsibility. Her leadership has been particularly effective among younger generations, many of whom feel that traditional political institutions have failed to adequately address environmental concerns. Through her communication and activism, Thunberg has inspired many young people to participate in political discussions and environmental advocacy.
Chapters 5 and 6 of Leadership: A Communication Perspective discuss the role of power and influence in leadership. Greta Thunberg demonstrates several forms of power described in the text. One of the most important is referent power, which arises when followers admire a leader and identify with their values. Many young activists see Thunberg as a representative of their generation and relate to her concerns about the future of the planet. This identification increases her ability to influence others. She also demonstrates elements of expert power through her reliance on scientific research and climate data. Although she is not a scientist herself, she frequently references scientific studies and encourages policymakers to follow the recommendations of climate experts. Informational influence is another tool she uses effectively. By sharing information about climate science through speeches, interviews, and online platforms, she raises awareness and encourages people to reconsider their perspectives on environmental issues.

Ethical leadership is another key topic addressed in Chapter 11 of the textbook. Ethical leadership involves considering the moral implications of leadership decisions and actions. Greta Thunberg’s activism raises several ethical considerations. On one hand, she uses her platform to advocate for environmental protection and to encourage governments to follow scientific evidence. Her message emphasizes responsibility toward future generations and the long-term health of the planet. These actions align with ethical leadership principles that prioritize the well-being of communities and society as a whole. On the other hand, her confrontational approach toward political leaders has generated debate about the role of activism in public discourse. Some critics argue that her tone can create division rather than cooperation. These differing perspectives highlight the ethical complexities leaders face when challenging powerful institutions and advocating for significant social change.
Greta Thunberg’s influence on society has been substantial, particularly among young people. The Fridays for Future movement has organized climate strikes in hundreds of cities around the world and has involved millions of participants. These demonstrations have increased public awareness of climate change and placed additional pressure on political leaders to address environmental concerns. Thunberg has also spoken at major international events such as the United Nations Climate Action Summit and the European Parliament, further amplifying her message. Her activism has contributed to a broader cultural shift in which climate change is increasingly viewed as an urgent political and social issue.
In conclusion, Greta Thunberg’s leadership illustrates how communication, persistence, and moral conviction can inspire global movements. Through her activism, she has mobilized millions of people to demand stronger environmental policies and greater accountability from political leaders. The leadership theories presented in Johnson and Hackman’s Leadership: A Communication Perspective provide useful tools for understanding how Thunberg has developed influence within the global environmental community. As Johnson and Hackman explain, leadership is “a form of human communication that influences the attitudes and behaviors of others to meet shared group goals.” Thunberg’s activism demonstrates this principle clearly, as her communication has inspired individuals around the world to take action on climate change. Her leadership highlights the power of communication to mobilize communities and address global challenges.
