India has emerged as one of the four major players in the vegetable oil scenario of the world. Vegetable oil scenario is complex and is highly influenced by various factors. For mitigating climate change by reducing emission of green house gases, meeting rural energy needs, protecting the environment and generating gainful employment, Jatropha curcas has multiple role to play. All efforts and endeavour to increase its production & productivity, oil extraction by application of appropriate technology, product development and diversification and policies that will protect and promote national interest world would be welcome.
