Earth Hour is an energy-saving movement initiated by the WWF against global climate change. It calls for individuals, communities, businesses, and governments to turn off non-essential electric lights and home appliances for an hour, at 20:30 local time on the last Saturday of every March (Mar. 25 for 2023), to show support for the planet and to raise awareness of environmental issues.

The world’s first Earth Hour began on Saturday, 31 March 2007 in Sydney, Australia, and has now grown into the largest global environmental movement that enjoys enthusiastic participation. This year, Earth Hour is given a greater purpose, uniting the power of participants from all walks of life for “The Biggest Hour for Earth” and pushing for changes to secure a brighter future for mankind and the planet.

Green Week of Calterah-ers

In response to the 2023 theme “Give an Hour for Earth”, Calterah launched the Green Week event from Mar. 20 to 26. The four sites of Calterah, Shanghai, Shenzhen, Hangzhou, and Suzhou offices designed a series of activities, online and offline, to engage indoor and outdoor participation of Calterah-ers, in an effort to raise awareness and encourage green behaviors for environmental protection.  

Calterah Green Week started with educational materials, including lock screen wallpapers, tips shared through an all-staff email, and the official promotional video, which aimed at appealing to everyone’s eco-awareness.

Online activity of posting daily green behaviors lasted for the whole week. Calterah-ers recorded their public transport commute and use of non-disposable shopping bags, coffee mugs, and chopsticks. These environmental behaviors are vivid embodiments of carbon footprint reduction.    

Reducing Carbon Emission

On Friday, various outdoor activities were organized:

• Shenzhen Office: Hiking along an ecological corridor to leave behind pressure and take away litter
• Hangzhou Office: Paying a tribute to those who keep the city clean

These activities were meant for raising environmental awareness and encouraging green behaviors, by combining healthy lifestyles and green outdoor activities.       

Lights-Off Moment

The event came to a climax at the office lights-off moment on Friday.

When the lights were off, the planet got to breathe. Amid darkness, we lighted up our concerns for the earth.

• Mediation—The hour we gave for the earth was not only for healing the planet, but also for enjoying a purifying journey in our mind.
• Plogging—A perfect match of health and environmental protection.

Snapshots of Green Happiness 

In particular, under the mission of “Make Millimeter-Wave Serve Everyone”, Calterah SoC products are enabling more and more green applications: home appliances with auto on/off, AC with auto airflow towards people, etc.

We, both Calterah-ers and Calterah, are doing our bits to help protect the planet. And we would like to also invite you to join us and turn Earth Hour into every minute of our lives.
