Himanshu Shekhar Nayak is a banker, author, climate and sustainability thought leader, NetZero advocate, social reformer, and motivational writer committed to creating positive change through awareness, action, and ideas.

With over 24 years of experience in the banking and finance sector, he strongly believes that values, integrity, discipline, and long term vision are essential not only for professional success, but also for building stronger institutions and a better society.

Alongside his professional journey, he has dedicated himself to environmental awareness, sustainability advocacy, and social thought leadership. Through his books, speeches, seminars, and mission driven initiatives, he works to inspire responsible living, ethical thinking, and practical action for a more balanced and sustainable future.

Environmental protection is not just a public cause for him; it is a deeply personal passion and a way of life. For the past 11 years, he has been actively involved in tree plantation and environmental awareness programs across schools, colleges, and communities, encouraging practical action for a greener and more responsible future. What began as a grassroots movement through Green Parikud, launched on 3 July 2015 in his native village, has gradually evolved into a broader environmental mission rooted in action, awareness, and public participation.

He has supported this mission not only through time and leadership but also through personal financial commitment, dedicating 20% of his monthly salary and 50% of his annual bonus toward social and environmental causes, with a major focus on tree plantation and environmental awareness.

He is associated with Green Parikud, a grassroots environmental movement; NetZero Planet, a large scale tree plantation drive across India with the vision of planting One Crore Trees by 2030; and NetZero Planet Foundation, which provides complete environmental solutions for institutions, communities, and organizations.

As an author, Himanshu Nayak has written on themes that are deeply connected to the future of humanity, including climate change, trees, carbon footprint, ESG, water crisis, air pollution, soil degradation, waste, wildlife conservation, social awareness, motivation, and responsible citizenship.

His writing style is simple, practical, and purpose driven, making important and often complex subjects accessible to readers from all age groups and backgrounds. He also conducts seminars and invited talks in schools, colleges, universities, and institutions on climate awareness, sustainability, human values, leadership, discipline, and purposeful living.

Through his books, environmental engagement, and public speaking, he seeks to inspire a future where economic progress, human values, social responsibility, and environmental sustainability move forward together.
