The 12th edition of Earth Hour was observed across the world by turning off non-essential electric lights for one hour from 8:30 pm to 9:30 pm on March 24,2018. It is the world's largest grassroots movement for the environment where people around the globe unite to take a stand against climate change by turning off non-essential lights for one hour. It is a global initiative of the World Wide Fund for Nature India or WWF-India. In 2018, WWF-India has launched the Give Up to Give Back initiative to inspire organisations, institutions and individuals to make the choice to curb some habits, practices and lifestyles that burden lives and environment. The campaign includes taking steps like giving up single-use plastics, fossil fuels and e-waste among others.
