As we celebrate Earth Day 2026 under the theme “Our Power, Our Planet,” we must confront the paradox of ICT. Although technology helps us lead more efficient and productive lives, it is also accelerating the decline of the planet. We discuss key current challenges and offer some practices that individuals and organisations can adopt.

 

As we commemorate Earth Day 2026, which occurred on 22 April, we must acknowledge that the global conversation on the environment, and the Inconvenient Truth, has shifted. No longer is “going green” a peripheral national policy or corporate social responsibility goal; it is now a fundamental requirement for survival in a digital-first world.

Although ICT is often hailed as the saviour of the planet—thanks to enabling remote work and optimising energy grids—it also carries a growing environmental debt that we can no longer ignore. In this article, we highlight some of the pressing tech issues and their impact on the environment, as well as provide some strategies we can employ to achieve a greener planet.

 

The pressing challenges in the ICT landscape

To a considerable degree and over the past 50 years, in particular, there has been a rapid acceleration in technology, which shows no signs of slowing down, and may even be experiencing even more rapid development as we try to harness new and emerging technologies. To that end, numerous ICT-related issues ought to be addressed to return us all to having a greener planet. We highlight the most pressing ones.

1. The energy demand of AI

The defining ICT challenge of 2026 is the energy intensity of generative AI. Training a single large-scale model can consume as much energy as a hundred homes use in a year. There is also a paradox that is worth noting. While AI is used to optimise energy grids and climate modelling, the energy required to train and run these models is skyrocketing

As countries and businesses integrate AI into every facet of operations, the demand for 24/7 power has led to a resurgence in the use of fossil fuels to stabilise energy grids, threatening global net-zero commitments. For example, tech giants, such as Google and Microsoft, have reported significant increases in emissions (up to 50% in some periods) due to AI infrastructure investments, threatening their 2030 net-zero goals (Source: NPR)

2. The e-waste tsunami and rare earth scarcity

Our culture of throwing out the old and replacing it with the shinier new, on increasingly shorter replacement or upgrade cycles, be they clothes or digital devices, has created a massive waste problem. In the tech space, ICT replacement cycles are often driven by marketing timelines rather than device failure, and many countries, especially those of the Caribbean, have limited landfill spaces and/or are struggling with implementing and maintaining appropriate waste management systems.

Further, electronics tend to contain rare earth minerals whose extraction is environmentally devastating. When these devices are discarded, they often end up in landfills, leaching toxic chemicals into the soil and water. The challenge thus lies in moving away from a linear take-make-waste model to a circular one.

3. Data centre water consumption

Beyond electricity, data centres require vast amounts of water for cooling. In a world where water security is becoming a geopolitical flashpoint, the massive water (as opposed to carbon) footprint of the cloud is a growing concern. For example, a medium-sized data centre, which would range in size from 10,000 to 50,000 square feet (or around 950 to 4,500 square metres), is estimated to use up to 5 million gallons (or 18,927,059 litres) of drinking water per day. Globally, the annual water consumption by data centres has been estimated at 148 billion gallons (560 billion litres).

It is thus not surprising that in drought-prone regions, the competition between ‘tech water’ and drinking water is becoming a major regulatory and ethical flashpoint, which emphasises the urgency in balancing the need for digital infrastructure with the basic human right to water.

 

Twin transition, and why it matters

Evidenced by the previously outlined ICT-related issues, climate change is no longer a distant threat but a lived reality, manifesting in more frequent natural disasters and resource scarcity. At the same time, ICT has now become vital to global civilisation, to the point where its resilience and sustainability are directly tied to our own. However, if the tools we use to solve climate change are themselves contributing to the problem, we are merely running in place.

The concept of the “twin transition” refers to the simultaneous evolution of our digital and green economies. In other words, we need greener practices because the Earth is being pushed to its limits. Through a twin transition, a synergistic approach combining digital transformation and green sustainability can be employed that leverages digital technologies, such as AI, the Internet of Things, and cloud computing, to accelerate climate action while using environmental goals to drastically reduce its own heavy footprint.

 

An action roadmap that contributes to a greener planet

To a considerable degree, the ICT-related challenges are systemic, and so are intrinsic to how these technologies work. Nevertheless, both individuals and organisations have the power to steer the digital trajectory toward greater sustainability by adopting simple strategies.

First, we as individuals can engage in digital sobriety, which is the practice of using digital tools in a responsible, moderate, and sustainable manner to reduce the environmental impact of technology. For example,

  • Aim to keep smartphones and laptops for at least five to seven years. Also, supporting the right to repair movement and choosing modular devices can significantly reduce your personal e-waste.
  • Practice digital hygiene by, among other things, unsubscribing from unnecessary newsletters and deleting unused cloud photos and documents. Every gigabyte stored in the cloud has a carbon cost, so being individually prudent with how digital space we occupy adds up.
  • Reduce video quality from 4K (or Ultra High Definition) to High Definition (HD) resolution on small screens, which in turn can reduce data-related energy consumption by up to 30%.

On the other hand, among organisations, the objective is sustainable governance, which generally speaks to the integration of environmental, social, and economic considerations into an organisation’s core decision-making, policies, and structures to ensure long-term viability and ethical accountability. Some of the ways in which sustainable governance  can be implemented include:

  • Adopting ‘green coding’ by ensuring that software architects prioritise energy-efficient programming languages and optimise algorithms to require less processing power.
  • Only partnering with cloud and other digital services providers, or procuring digital goods and services from providers that offer transparent, location-based carbon reporting and use waste-heat recovery systems to warm local communities.
  • Prioritising resilience, especially in regions vulnerable to climate-related disasters, by investing in Hurricane-ready (or other disaster-ready) ICT infrastructure and practices, such as using solar-powered backup systems and decentralised networks that can withstand extreme weather, or facilitate speedier recovery in the aftermath of a disaster.

 

Parting thoughts

Earth Day 2026 serves as a reminder that the Earth, our Earth and home, is under considerable threat. Moreover, there is an environmental cost to our digital lives. However, outside of global, regional or national policies or strategies, we all can play our part by making more prudent choices and reducing our environmental footprint. In doing so, we can ensure that technology remains a tool for restoration rather than depletion.
