Earth Hour 2025: Thousands of Young Families Support Net-Zero

Hanoi, March 22, 2025 – This year’s Earth Hour event at Hoan Kiem Lake was more than just a call to turn off the lights – it was a vibrant celebration of community action for sustainability. Families, students, and businesses came together in a festival of energy efficiency, renewable energy and environmental awareness, reinforcing Viet Nam’s commitment to Net-Zero emissions.

One of the most engaging activities was the power-generating cycling challenge, where children and parents pedaled to light up the event’s “I am for Net-Zero” LED board. Eight-year-old boy Hoang Bach excitedly shared, “It’s so cool that my bike can make electricity! I want to save energy at home, too.” His mother, Ai Van, added, “This activity is a great way to show kids that small actions make a difference. It’s inspiring to see so many families here learning about green energy together.”

Another highlight was the creative check-in area, featuring a replica of a traditional Hanoi balcony equipped with solar panels. This installation blended heritage with innovation, sending a strong message about integrating renewable energy into daily life. “We took so many photos here – it’s a perfect symbol of how Hanoi can embrace green energy while preserving its identity,” said Anh Minh, a pedestrian attending the event.

The “Green Move” flash mob performance by students from various universities electrified the crowd, reinforcing the event’s message through dance and music. Additional artistic performances celebrated sustainability, making the event a fun and educational experience for all ages.

The IKI funded project “Clean, Affordable and Secure Energy for Southeast Asia (CASE)” played a supporting role alongside government agencies in organizing the event, contributing to a collaborative effort to advance Viet Nam’s energy transition. This collaboration brought together key stakeholders in Viet Nam’s energy transition, reinforcing the collective effort needed to drive lasting change.

Vu Chi Mai, representative of GIZ Energy Support Programme (ESP) under the Deutsche Gesellschaft für Internationale Zusammenarbeit, emphasized the importance of long-term behavioral change: “This marks our third year supporting Earth Hour in Viet Nam. Through a series of informative and inspiring activities under the theme “Green Transition – Green Future”, we hope to encourage individuals and organizations to take action for a more sustainable future. Our goal is to embed energy efficiency and renewable energy into everyday habits, making them a natural part of daily life. In doing so, we contribute to building a green economy.”

Dr. Nguyen Ngoc Thuy, National Coordinator of Energy Transition Partnership (ETP), remarked: “The strong public engagement in Earth Hour proves the power of collective action. Through initiatives like this, we aim to inspire responsibility and encourage all to contribute to a just energy transition. By raising awareness and fostering participation, we can turn sustainability into a national movement, ensuring that green habits extend beyond just one event and become an integral part of daily life.”

As the community came together in support of Earth Hour, government representatives and industry leaders also shared their insights on Viet Nam’s green transition, recognizing both the challenges and the opportunities ahead.

Le Anh Thu, Vice Chairwoman of the Hoan Kiem District People’s Committee, highlighted the urgency of energy conservation: “This summer is expected to be the hottest on record, surpassing 2024. In response, Hoan Kiem District has successfully saved 15.4 million kWh of electricity in 2024 and aims to reduce consumption by another 2.2% in 2025. Though a small number, it reflects our commitment to raising awareness and promoting a sustainable lifestyle in every neighborhood. Every step counts, and together, we can create a ripple effect that extends far beyond our district.”

Pham The Dung, Deputy Head of the State Agency for Technology Innovation, stressed the broader impact of the event: “Green transition is not just a trend but a key driver of national competitiveness. Earth Hour 2025 serves as a platform to promote clean energy, encourage innovation, and integrate green technologies into daily life. It is through collective efforts that we will see real change, strengthening Viet Nam’s position as a leader in sustainable development in the region.”

Beyond the lively celebrations, Earth Hour 2025 delivered tangible results: Viet Nam saved 448,000 kWh of electricity within one hour, equivalent to approximately 942.2 million VND. More than just a symbolic act, this achievement underscores the collective impact of individual actions. It is a testament to the growing awareness and commitment of Vietnamese citizens towards energy efficiency and environmental protection.

Tran Viet Nguyen, Deputy Head of Business at Vietnam Electricity (EVN), echoed this sentiment: “This year’s Earth Hour underscores the need for action. A green future requires the engagement of individuals, businesses, and policymakers. We urge the public to be mindful of electricity use, especially during peak hours, to alleviate strain on the grid and contribute to a sustainable energy future. Small changes in energy consumption habits today will lead to long-term benefits for future generations.”

With thousands of young families actively participating, the movement for sustainable living continues to gain momentum, paving the way for a greener, brighter future. The energy and enthusiasm witnessed at Earth Hour 2025 serve as a powerful reminder that when communities unite for a cause, meaningful change is not just possible – it is inevitable.
