The World Earth hour was observed at our center by switching off all lights, except that for emergency, from 8.30 PM to 9.30 PM. This 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. WTC could save around 25% of energy from this activity. The theme of 2022 'Shape our future' signifies an important year for people and the planet. Building complexes and establishments globally observe the day thereby highlighting our collective responsibility towards the environment.
