Prathiba Karthikeyan
Prathiba is a Partner in Corporate and M&A practice at LKS New Delhi. Prathiba Karthikeyan is a seasoned legal and tax professional with over 15 years of experience spanning indirect tax law, international taxation, carbon markets and climate finance policy. A Chartered Accountant and qualified lawyer, she brings a rare combination of deep technical expertise and cross-jurisdictional exposure, having advised multinational corporations in India and worked with leading international institutions across Europe.
Prathiba began her career at Lakshmikumaran & Sridharan Attorneys (LKS), where she rose to Joint Partner and led a team advising MNC clients in the manufacturing, automotive and consumer goods sectors on indirect tax law, GST implementation and customs compliance.
Following her tenure at LKS, Prathiba pursued an LL.M. in International Business Law and Innovation at the University of Lausanne (UNIL), graduating Summa Cum Laude. Her thesis examined the legal framework around greenwashing through carbon offsetting, with a critical comparative analysis of EU and Indian regulatory regimes, reflecting her focus at the intersection of regulation and sustainability.
Her diverse training engagements, including those at the OECD's Global Forum on Transparency, supporting carbon credit project development at UpEnergy Group and advising philanthropic initiatives at Impact Philanthropy Advisors GmbH (now Impact Trust) in Liechtenstein have contributed to her multi-faceted foundation and experience.
She has since focussed on building a practice in climate change and sustainability, ranging from advising carbon projects on Project Design Documents (PDDs), carbon credit rights, land tenure, taxation, data protection and carbon pricing frameworks, while also contributing to academic course development on climate finance and carbon markets, and contributing to policy-oriented articles for policy think tanks.
