1. Choose Energy-Efficient Devices

One of the simplest ways to lower your tech carbon footprint is by selecting devices that consume less energy. Many manufacturers now prioritize energy efficiency, helping consumers reduce both electricity usage and overall emissions.

Look for Energy-Efficient Certifications

When purchasing new devices, check for environmental certifications that indicate lower energy consumption:

Energy Star: A U.S. government-backed certification for energy-efficient electronics and appliances.
EPEAT (Electronic Product Environmental Assessment Tool): Rates electronics based on energy efficiency, recyclability, and use of environmentally friendly materials.

Opt for Low-Power Components

Certain hardware components consume less energy while still delivering excellent performance:

ARM-based processors: Found in Apple’s M-series chips and many mobile devices, these processors use less power compared to traditional x86 chips.

Solid-state drives (SSDs): More energy-efficient and faster than traditional hard disk drives (HDDs).

OLED and e-ink displays: OLED screens use less power than LCDs, while e-ink displays (used in e-readers like the Kindle) consume almost no energy when displaying static content.

Optimise Device Settings for Efficiency

Small adjustments to your device settings can significantly reduce power consumption:

Lower screen brightness and enable dark mode when available.
Activate battery saver mode to limit background processes.
Set devices to enter sleep mode after a short period of inactivity.

By choosing energy-efficient devices and making simple optimisations, you can cut down on unnecessary power usage, lowering both your electricity bill and environmental impact.

2. Extend the Lifespan of Your Tech

One of the most effective ways to reduce e-waste and your tech carbon footprint is to keep your devices for as long as possible. The longer you use a gadget, the less frequently new ones need to be manufactured—reducing resource extraction, emissions, and waste.

Premium vs. Budget Products: The Longevity Factor

When buying new tech, consider long-term durability rather than just upfront cost. Premium and high-quality devices (e.g., MacBooks, ThinkPads, flagship smartphones) often last longer due to better build materials, repairability, and longer software support. While they come at a higher price, their extended lifespan makes them a more sustainable choice.

Budget and low-end gadgets may seem cost-effective initially, but they often have weaker components, shorter support cycles, and are more likely to break or become obsolete quickly. Many cheap devices lack replaceable parts, making repairs difficult or impossible.

Choosing a longer-lasting device means fewer replacements over time, reducing both e-waste and the carbon footprint associated with manufacturing and shipping.

Maintain and Upgrade Instead of Replacing

Proper care and timely upgrades can extend the usability of your tech:

Regular cleaning: Keep devices free of dust and dirt, especially cooling fans and vents.
Battery management: Avoid deep discharges and extreme temperatures to preserve battery health. We have written a guide on how to extend the life of your smartphone battery, do check it out.
Upgrade instead of replacing: Add more RAM or swap out an old hard drive for an SSD to improve performance rather than buying a new device.

Protect Your Devices

Preventing physical damage can significantly extend your device’s lifespan. Use protective cases and screen protectors for smartphones and tablets. Invest in a surge protector to guard against power fluctuations. Last but not least, handle laptops and electronics with care to prevent accidental drops or spills.

By investing in durable, repairable devices and taking good care of them, you not only save money but also contribute to a more sustainable tech ecosystem.

3. Reduce E-Waste Responsibly

E-waste is one of the fastest-growing waste streams globally, with millions of devices being discarded every year. Many of these contain valuable materials like rare earth metals, which require energy-intensive mining. Instead of throwing away old tech, consider more responsible disposal methods.

Sell, Donate, or Repurpose Old Devices

Before disposing of a device, explore ways to extend its use with these three tips. Sell or trade-in old gadgets through manufacturer programs (e.g., Apple, Samsung, Dell) or marketplaces like eBay, Back Market, and Swappa. Second, donate working electronics to charities, schools, or community centers where they can still be useful. Third, repurpose old devices for new uses, such as turning an old smartphone into a dedicated music player, security camera, or digital photo frame. We have a huge resource on how to repurpose and upcycle old tech products. See articles below:

Recycle E-Waste Properly

If a device is truly unusable, ensure it is disposed of responsibly. Use certified e-waste recycling programs like those provided by local governments or companies such as Best Buy and Staples. Some manufacturers offer take-back and recycling initiatives to safely recover materials from old devices. Never throw electronics in regular trash bins—many contain hazardous substances that can leach into the environment.

By extending the life of electronics and ensuring proper disposal, you can reduce the environmental harm caused by e-waste.
