Kolkata, March 23 (IANS) Some citizens of Kolkata Saturday resolved to limit the use of paper and increase the use of recycled paper as a prelude to the observance of Earth Hour, the global initiative to save energy and reduce global warming.

Earth Hour is a global campaign that India first joined on March 23 2009. The movement involves millions of people in 7,001 cities and towns across 152 countries (including India). Electricity is switched off for one hour as a show of solidarity towards the cause of the environment.
This year, Earth Hour is being observed Saturday from 8.30 p.m. to 9.30 p.m..
In Kolkata, many hotels like the Park hotel, adopted the ‘no-printouts’ norm throughout the day. Employees as well as guests were requested to refrain from charging their mobile phone batteries during the day.
Similarly the Sonnet Hotel, touted as an eco-friendly establishment, in association with Media Connect, urged employees and guests to use recycled paper.
Guests also participated in a poster-designing contest and bought Earth Hour themed T-shirts.
Expressing solidarity with the campaign, cadets of the National Cadet Corps took out a rally from NCC Club House premises to Park Street.
Evolving beyond the one-hour clause, ‘Earth Hour’ now includes continuous actions towards saving the environment.
India joined the Earth Hour movement in 2009, when five million Indians across 56 cities showed their support by switching off non-essential lights and saving approximately 1,000 MW of power in that one hour.
More than 150 Indian cities participated in the campaign in 2012.
