In September 2017 she published "The Business Plan for Peace: Building a World Without War" (Peace Direct, 2017). The Business Plan for Peace demonstrates how 25 tried and tested strategies for preventing war could be scaled up and extended over 10 years, with the aim of preventing armed violence worldwide. The total cost came to as little as two billion dollars, when the cost of militarization worldwide now exceeds US$1,686 billion. The book further demonstrates how people in any country can learn the skills to prevent conflict and apply them in their own communities, schools, workplace and families. The response has been so favourable that many of the strategies are now being implemented as programmatic initiatives of a new organisation with a viable business plan for peace. Elworthy is currently building a team to enable this powerful vision to flourish. When she has time she advises the leadership of selected international corporations on investing in and strengthening their respective roles in preventing violent conflict, and teaches young social entrepreneurs.
