Greenpeace activists label as "stupid" the illegal erection of a steel structure and back-filling on a proposed site for a coal-fired power plant in Iloilo.

Coal plants are the largest contributor to greenhouse gas emissions responsible for climate change that manifest in extreme weather events like typhoons Frank, Ondoy (Ketsana) and Pepeng (Melor).
