4 Eco-Friendly Tech Tips to Shrink
Your Carbon Footprint

From repurposing old devices to charging less often, here are a few easy ways to make a difference.

Tackling climate change is going to take big, bold action. But the little choices you make every day can also help. By lowering your carbon footprint—the measure of how much carbon dioxide and greenhouse gas you generate—you’re making a small, consistent impact, and shifting your sustainable technology habits is a great place to start. Here’s how.

Find a new use for old devices

When it comes to setting up an energy-friendly home, you don’t have to start from scratch. If you have old phones gathering dust in a drawer, it’s easy to give them new life with the Galaxy Upcycling at Home¹ program.


Automate your home to save energy

Half the challenge of reducing energy consumption is just remembering to do it, whether it’s turning off the lights in empty rooms or lowering the air-conditioning when it’s not needed. Luckily, home automation makes it so you don’t have to remember. By connecting your Galaxy S21 to SmartThings devices, you can create a simple Bixby Routine that automatically turns smart lights⁴ on or off and manages their power use. Good for the planet. Good for your energy bill.


Make your charges last longer

The less often you charge, the more energy you save—and there are plenty of features designed to help your battery go further. On the Galaxy S21, you can turn on settings like Battery Optimisation or Dark Mode, and turn off features that use a lot of power and don’t need to be on 24/7 (Always On Display and Location, for example). The phone can even adapt its power usage to your personal habits with Adaptive Power Saving mode.

Global Goals

Scroll for a good cause

Supporting the fight against climate change can be as easy as casually tapping a few ads. On your Galaxy S21, there’s an app called Global Goals that was made by Samsung and the United Nations. In the app, any ad you interact with donates revenue to one of the Global Goals, which include Climate Action and Responsible Energy Consumption and Production. You barely have to lift a finger. OK, just the one to tap the ad.
