A new study has revealed that using digital devices contributes to the production of carbon dioxide through internet data consumption—a factor many users are unaware of. Carbon dioxide is a greenhouse gas that plays a major role in rising global temperatures and climate change.

While traditional sources of carbon emissions like vehicle smoke, factory pollution, and deforestation are widely recognized, researchers are now highlighting the invisible impact of digital activity. The study shows that using phones, smart devices, Bluetooth speakers, tablets, and even wearable tech generates emissions through the energy consumed by data centers, cloud servers, and connected infrastructure.

Climate advocate and internet specialist Ian Chew from Greenie Web explained that carbon emissions are generated at every stage of the digital process—from personal gadgets to international data cables. “We can see how data flows from computers, hand phones, smart Bluetooth speakers, wearables, and even pet collars. All of this ends up in data centers where most of the processing and storage is done,” he said.

According to Mozilla Foundation, emissions from communication devices powered by non-renewable energy make up the fourth largest contributor to global greenhouse gases. The study found that one hour of video conferencing on Zoom produces about 1,000 grams of carbon dioxide, while one hour of Netflix streaming generates about 100 grams. Astonishingly, ChatGPT alone is estimated to produce 7.6 metric tons of carbon dioxide annually.

Chew warned that digital carbon output will likely increase in the future as demand for internet access, apps, and software continues to grow. He added that the environmental impact of data centers, servers, and international fiber-optic cables—including those connecting Vanuatu—must be considered.

To address the issue, Greenie Web is working on “digital decarbonization” by redesigning websites, mobile applications, and even blockchain systems to make them low-carbon. Their software helps businesses and developers convert digital platforms into greener versions that consume less energy.

Chew emphasized the need for awareness, especially in schools and high-level offices. He urged businesses to review their digital strategies and take steps to reduce their digital footprint, promoting the use of the internet in more climate-friendly ways.
