The GDP (Gross Domestic Product) is the way every country on earth measures their development. But this pursuit of economic growth at all costs created an unsustainable system that pushed the well-being of people and the planet to its limit. As the largest financial newspaper in the world and creator of Japan's most prominent stock exchange index, Nikkei recognized they played a role in perpetuating the problem. Now they wanted to be at the heart of a sustainable solution.

Working together with Harvard, Oxford and Tokyo University, Nikkei developed the Well-Being Index (GDW). A transformative new way to measure a country's growth, focusing on the well-being of its citizens and not just its economy. Used alongside the GDP, the new Gross Domestic Well-being index becomes an official metric for governments and companies to inform new decisions, investments, and policies.

To ensure adoption by companies and government, the new GDW Index was introduced to policy-makers and the largest traded  companies in Japan through a series of symposiums. Leveraging its position as one of the biggest media organizations in Japan, thelaunch was supported with newspaper ads and articles, while a dedicated team worked with government officials to establish the GDW as an official metric alongside the GDP. The GDW index was then regularly published next to the GDP in the biggest financial newspaper on the planet, the Nikkei.
