Last summer, our organisation, the Hong Kong Committee on Children’s Rights, hosted a forum titled “I Have Something to Say,” providing a platform for those aged 10 to 17 to voice their thoughts. Topics were unrestricted, as long as they were child-related and lawful.

The very first issue raised was: “Hong Kong needs to establish a Children’s Day to raise public awareness of children’s rights.”

The young boys who raised the issue were sixth graders who, at the time, would be heading off to different secondary schools after the summer break.

They made a demand on behalf of all children in Hong Kong. One of them said, “Adults often use holidays like Valentine’s Day and Christmas to organise fun celebrations. Why is there so little promotion for Children’s Day?”

There is no universally agreed date for Children’s Day around the world.

In mainland China, June 1 is designated as Children’s Day, giving students under 14 a day off from school. Celebrations include large-scale group performances, school fairs, gift-giving, and parent-child activities. Taiwan’s Children’s Day falls on April 4, which is a national holiday. It features a host of fun, family-friendly activities and sporting events.

Both Japan and South Korea celebrate Children’s Day on May 5 – a public holiday. In Japan, carp streamers are hung, symbolising courage and growth, while in South Korea, there are large-scale events across the country.

In contrast, Children’s Day is usually just another day in the classroom for students in Hong Kong, though some schools and NGOs choose to celebrate it on either April 4 or June 1.

The kids at our forum were not speaking solely from a self-interested perspective. They argued that establishing a Children’s Day would be a concrete implementation of the United Nations Convention on the Rights of the Child, which came into force in Hong Kong in 1994.

They pointed out that “many countries use Children’s Day to host legal awareness campaigns, promote the prohibition of child labour, improve educational resources, organise visits to parliaments to learn about democratic systems… and so on.”

The young boys weren’t just clamouring for playtime. They had done their homework. I silently marvelled.

Whether it’s April 4, May 5, June 1, or November 20 – the last being World Children’s Day, marking the UN General Assembly’s adoption of the Declaration of the Rights of the Child in 1959 and of the Convention on the Rights of the Child in 1989 – Hong Kong should formally designate Children’s Day as an official holiday, joining its East Asian counterparts.

The boys conducted a survey at their primary school in Tin Shui Wai and found that only half of their schoolmates knew about Children’s Day.

“Today’s children face academic pressure and excessive use of electronic devices, leading to a year-on-year rise in mental health issues such as depression and anxiety,” they said.

“Official Children’s Day celebrations can provide dedicated relaxation opportunities for children, such as schools organising fun activities and families arranging parent-child interactions, helping children reduce stress and cultivate positive emotions,” they suggested.

“Children’s Day should also draw society’s attention to the circumstances of vulnerable children (such as those living in poverty, with disabilities, or experiencing abuse), mobilising donations, providing resources, and fostering empathy for their situations.”

‘Crucial opportunity’

Holidays need not be merely dazzling celebrations. As the boys said, “It’s a crucial opportunity for society to examine children’s rights and invest in the future. Its significance extends far beyond a single holiday – from individual growth to societal progress – requiring joint efforts from governments, families, and educators.”

Shouldn’t we adults feel ashamed of ourselves? Why has Hong Kong never placed Children’s Day on the agenda for discussion as a school holiday, public holiday, or statutory holiday? Or has society grown accustomed to treating “children” as mere decoration, where they appear only as embellishments and photo opportunities at festive occasions?

On many critical issues – even those directly affecting children, such as school lunch programmes, school governance, or the recently enacted Mandatory Reporting of Child Abuse Ordinance – society uses “age and maturity” as an excuse to exclude children’s voices, completely violating the Convention on the Rights of the Child’s principle of child participation.

Children have already voiced their evidence-based and heartfelt appeal. The ball is now in our court to show that they mean more to us than mere decorative value in our marketing campaigns. 

I believe the Hong Kong government and the Commission on Children will welcome this vision and lead the way in seriously considering the establishment of a holiday dedicated to Hong Kong’s 970,000 children under the age of 18.

Ultimately, by listening to children’s voices, we can build a culture that recognises them as individuals and as a distinct group, and learn to engage with their rights, rather than resist them. In doing so, we can set an example and help cultivate a generation of responsible and reflective decision-makers.

The adoption of sustainable technology is accelerating worldwide, whether in homes or businesses. Houses have smart thermostats, solar systems accessible from an app, and electric car chargers as part of their home networks.

Yet some people are choosing to purchase refurbished laptops, phones, and tablets to reduce the negative environmental impact and prolong device life.

However, much of this conversation around sustainability ignores a critical perspective: system security. These eco-friendly gadgets are connected to the internet, retain information, and interact with home energy solutions. When left unprotected, they can be disrupted and rendered useless, thereby shortening their lifespan and contributing to electronic waste.

This means sustainable living now also includes environmental impact and digital safety.

The Rise of Smart Home Technology

IT sustainability has shifted from a niche topic to a necessity. Homes and businesses are integrating products that value efficiency and extend product longevity. Yet, they tend to ignore the new digital risks they bring to users. One of the most obvious examples of the shift is the adoption of refurbished technology in smart homes.

Smart Homes and Renewable Energy Devices

Smart energy devices help households monitor and manage energy use, promoting efficiency and cost savings. Connected thermostats can adjust the temperature based on a household’s real-time needs and energy pricing. Many solar panel systems come with mobile apps that track energy production and storage. EV chargers connect to the home Wi-Fi to charge at off-peak times or when electricity prices are lower.

They help meet climate goals by improving efficiency and reducing emissions. But most tools rely on the internet and cloud services. So, without difficult passwords and high-security networks, smart devices are common targets.

The Growth of Refurbished and Second-Life Electronics

Refurbished electronics help devices last longer, keeping valuable materials in circulation and reducing electronic waste. Buying a refurbished smartphone or laptop is better for the environment than buying a new one, and many companies are now promoting repair, reuse, and resale to support a circular economy.

But second-life devices can also have hidden cybersecurity risks if users don’t take basic precautions. Basically, old accounts, forgotten software, or leftover data can still be on the device. Before using a refurbished electronic device, wipe the storage completely, reset the operating system, and install the latest security updates.

Digital Threats Can Undermine Sustainable Choices

Smart home technology relies on connected systems and integrated digital services. However, these connections to the web also attract cybercriminals and scammers, who prey on unsuspecting users by tricking them into providing sensitive information or visiting malicious websites.

Cybersecurity threats can compromise energy supply, steal personal data, and force users to reset or replace devices. Each incident chips away at the long-term value of sustainable technology, so staying aware and following some steps helps achieve the goal of sustainability.

The Hidden E-Waste Cost of Cyber Security

When connected devices are compromised, the downfall goes beyond loss or inconvenience. Essentially, a hacked or lagging device often gets abandoned or replaced, even when that isn’t necessary. This act directly adds to waste.

This becomes a major issue as it reduces the lifespan of the device you’re using, the one designed to support sustainability goals when manufactured. Hence, cybersecurity becomes the central theme in the circular economy, where protecting devices is the key to making them functional, usable, and out of landfills for a longer time.

This way, technology stops being only a digital concern, as its impact also spills over into environmental ones.

Fake Alerts, Phishing, and Social Engineering

Although many cyberattacks rely on technical complexity, others succeed by using simple manipulation. Fake security notifications and unusual pop-ups are designed to panic you.

These notifications usually look exactly like typical system warnings or software notifications, which is what makes it difficult to differentiate them from the real ones. My company authored an article on the methods that work can help users pause and avoid leaking any of their important information. Such analysis of fake alerts allows you not only to protect information and detect the tell-tale signs of manipulation attempts.

By leveraging the psychology of urgency, hackers can override your sense of reason. So, pausing before you react to clicking any warning or link will heavily serve you in these situations.

Steps to Keep Sustainable Tech Secure

Sustainable technology makes the most impact when it is long-lasting and safe. A bad enough attack can affect the life of the device, exposing information or bringing down energy systems.

Thankfully, adopting simple cybersecurity practices protects these devices and helps people continue to use this eco-friendly tech for years.

Secure Smart Energy Devices and Home Networks

Each smart device creates another doorway for criminals. According to the IBM X-Force Threat Intelligence Index 2025, almost one in every three cyberattacks abuses stolen credentials, usually obtained from phishing attacks.

Protect your smart energy technology with these security steps:

1. Change default passwords now. Most manufacturers ship devices with easy access login credentials.
2. Keep everything updated. Security updates generally fix existing bugs and common weaknesses.
3. Use a separate network for smart devices. Create a guest or IoT network on your router (if available).
4. Disable unused features and remote access. The more features your devices have, the more they may be exposed, so review features that you do not use and disable them.
5. Check device activity. Regularly examining logs and dashboards for weird connections and activity.

How to Choose Your Refurbished Device

Using a second-hand device does support the environment, but they aren’t all the same, as the source matters for both security and sustainability. Picking a refurbished product from a certified refurbished source, such as one accredited under R2 (Responsible Recycling) or e-Stewards standards, gives you an additional layer of assurance.

Since these certifications require adhering to strict standards for data wiping and responsible handling of components, their devices tend to be more secure, as you’d be sure that previous user data was cleared adequately.

Protect Refurbished and Second-Hand Devices

Responsible re-use promotes a circular economy and reduces environmental harm caused by electronic waste.

Use these steps when buying secondhand electronics:

1. Do a thorough factory reset. Reset the device to factory settings before adding accounts. This eliminates leftover files or settings from prior users.
2. Install existing security and operating system updates. Older operating systems often come with exploitable vulnerabilities that the manufacturer has since addressed.
3. Scan the device. Once the device is set up, run a trusted scan. This helps find hidden software or unusual extensions.
4. Remove unused accounts and apps. Check lists of accounts, extensions, and installed programs for unrecognized items. Delete anything you are not using.
5. Encrypt and back up your data. Encrypting your files ensures they’re secure if your device is lost or stolen, and regular backups prevent data loss and extend your device’s useful life.

Protecting Data and Reducing E-Waste with Secure Disposal

Unfortunately, even if you take good care of your device, there will come a point where you have to dispose of it properly. When you find yourself in need of getting rid of it, you need to know how to do so securely. Before recycling or throwing out electronic parts, make sure your personal data is completely removed by completing a full factory reset. Sometimes, you might have to resort to destruction to secure your data.

Once everything has been wiped, take the device to a certified e-waste recycling program or a collection site that adheres to the processing standards. This being the final step in your product’s lifetime, it is critical to do it properly to prevent sensitive data from being recovered, and it keeps the valuable materials within the circular economy.

Smart Home, Smart Choices

Sustainable technology, which is designed to reduce waste and save energy, is an integral part of our lives that we are increasingly relying on. But these benefits only hold if we ensure these technologies remain secure. Smart energy systems, connected devices, and refurbished gadgets hinge on safe digital practices to survive for a long period of time.

When a device is compromised, the consequences are beyond data loss, as this can lead to users being forced to replace them much earlier than intended, adding to electronic waste. Protecting systems, therefore, is not merely an issue of cybersecurity but a critical part of maintaining environmental value.

Security habits and sustainability go hand in hand, meaning when efficiently integrated, users can extend devices’ lifespans and reduce waste. This makes eco-friendly technology more efficient and more resilient over time.
