After the Fukushima disaster shut down Japan's nuclear reactors, the coal industry rushed in to fill the energy gap. As climate advocate Kimiko Hirata watched dozens of new coal plant proposals quietly surface across the country — each one locking in decades of future emissions — she resolved to make them impossible to ignore. She shares how a small, scrappy civil society movement took on a fossil-fuel-dependent economy and got people to say "yes" to a renewable future.

A cheat sheet for accelerating clean energy

When Japan’s nuclear reactors shut down after Fukushima, coal plants surged as a stopgap, risking decades of future emissions. A grassroots network mapped every project and rallied communities, achieving the cancellation of 17 new coal plants—preventing 50 million tons of CO2 each year. By shifting from saying no to building a strong yes for renewables, advocates are proving that even small groups can spark national change. Now, the focus moves from stopping coal to transforming the entire economy toward clean energy, city by city.

From Coal’s Comeback to a Renewable Revolution in Japan

After the Fukushima disaster, Japan faced a surge in coal plant proposals, risking decades of increased carbon emissions. A determined grassroots push led to the cancellation of 17 coal projects—avoiding 50 million tons of CO2 yearly, equal to removing eight million cars from the roads. By building networks, engaging communities, and focusing on real-world concerns like jobs and health, activists shifted the conversation from saying no to fossil fuels toward a collective yes for renewables. The ongoing challenge is to inspire systemic change, overcoming skepticism about renewable energy’s reliability and cost.
