The digital world, often seen as clean and immaterial, has a carbon footprint as large as industrial giants like the aviation industry, which is infamous for its environmental impact. In fact, the carbon emissions from our global digital activities are comparable to those of Germany, currently one of the world's largest polluters.

This impact stems from data centers, transmission networks, and the devices we use every day, all consuming substantial amounts of electricity. For instance, a single email with a large attachment can emit about 50 grams of CO2, equivalent to driving a car for about 450 meters. Moreover, the lifecycle of digital infrastructure, including frequent equipment updates and replacements, significantly contributes to its carbon output.

Despite these challenges, the digital sector holds a unique advantage: it operates on electricity. This means that unlike industries reliant on fossil fuels, digital operations can transition entirely to renewable energy sources. However, it's important to note that this transition may not be without its challenges, such as the availability and cost of renewable energy in certain regions. 

This guide will explore actionable strategies that can help your business not only minimise its digital emissions but also bolster your brand's commitment to sustainability.

  1. Streamline User Journeys



Here's how you can make a great user experience whilst reducing the environmental impact of digital activities:

  • Reduce Clicks: Make sure users can reach their goals with as few clicks as possible. Fewer page loading means less energy used.

  • Keep Shopping Simple: Some online stores, use a sidebar for the shopping cart. This lets users see and change their cart items without leaving their current page, saving energy and making shopping easier.

  • Clear Navigation: Make it easy for users to find what they need quickly. A well-organised site means users spend less time and energy searching.

  • Streamline Paths: Cut out unnecessary steps in the user's path. In online shops, making it faster to buy something can also lead to more sales.

  • Helpful Visuals: Use clear signs and indicators that show users where they are in their journey, helping them move forward without confusion.

By applying these simple steps, websites can greatly reduce their energy consumption while improving the overall experience for their visitors. This not only helps the environment but also enhances your brand's image as a sustainable and responsible entity, potentially attracting more environmentally conscious customers.

  1. Efficient Images


Using images wisely on your website can significantly reduce its carbon footprint. Here's how to make your images more efficient:

  • Use Fewer Images: Design your pages to rely less on heavy photographic content. Utilise colours, shapes, and textures to convey information aesthetically.

  • Opt for Vector Graphics: Vectors are much lighter than raster images because they don't store as much pixel data. This means faster loading times and less energy used.

  • Compress and Resize Images: Always optimise the size of your images. Smaller file sizes consume less bandwidth and energy. For example, reducing image dimensions can decrease the file size dramatically, sometimes by as much as 70%.

  • Simplify Images: Reducing the complexity of images, like blurring unnecessary details, can further reduce file sizes.

  • Use Black and White: Converting images to black and white can significantly decrease file size because colour data is more intensive to store.

  • Adopt Efficient Formats: Switch to more efficient image formats like WebP or AVIF, which provide high-quality visuals at a fraction of the file size of traditional formats like JPEG.


  1. Less Video


Videos are data-intensive; use them wisely to save energy:

  • Avoid Autoplay: This saves energy and data for users, particularly those on limited data plans.

  • Optimise Video Length and Quality: Shorter, lower-resolution videos can significantly reduce data usage without compromising user experience.

  • Choose Efficient Formats: MPEG4 is typically more efficient than other video formats, using less data for the same quality video.


  1. System Fonts



Using system fonts can also reduce your site's energy use:

  • Utilise Pre-loaded Fonts: System fonts like Arial or Times New Roman are already installed on most devices, which means they don't need to be downloaded again, saving data and energy.

  • Benefits of System Fonts: Using system fonts can make web pages load faster, improving the overall user experience.


  1. Optimise Custom Fonts

If custom fonts are necessary, they can still be optimised:

  • Reduce Font Weights and Variants: Limit the number of font styles and weights to those you actually need.

  • Subset Your Fonts: Include only the characters you use in your font files. This reduces their size dramatically.

  • Use Efficient Font Formats: Consider formats like WOFF2, which offer compression benefits and are designed specifically for web use.

6. Go Easy on the Icing

Minimising the use of complex visual effects can help reduce a website's energy consumption:

  • Limit Animations: While animations can enhance the look of a site, they require more processing power. Use them sparingly.

  • Simplify Transforms: Transformations such as rotating or scaling elements are processing-intensive. Evaluate if they are essential for your design.

  • Reduce Use of Masks: Clipping and masking graphics can add unnecessary load times and energy consumption. Use these features only when they significantly contribute to user experience.

  • Monitor Interaction Effects: Effects triggered by user interactions, like hovers and clicks, should be used judiciously to not only keep the design clean but also save energy.

7. Low Energy Colors


Optimising colour usage can significantly affect the power consumption of devices displaying your website, especially those with OLED screens:

  • Darker Shades Save Power: Using darker colours can save energy as they require less light from the screen to be displayed.

  • White and Blue Are Costly: On OLED screens, white uses the most energy because it lights up all colour components. Blue pixels use about 25% more power than red or green.

  • Opt for Greener Shades: Colors like red and green are generally less energy-intensive and can be used effectively to reduce overall energy consumption.


8. Track Less

Reducing the use of tracking scripts can improve both site performance and user privacy:

  • Slows Down Websites: Heavy tracking scripts can significantly slow down page loading times.

  • Invades Privacy: Excessive tracking can lead to privacy concerns among users, potentially deterring them from using your site.

  • Impacts User Experience: Overloaded tracking can make websites less responsive and harder to navigate.

  • Increases Energy Use: Tracking involves processing and transmitting data, which can increase the energy consumption of your website.

  • Business Impact: While useful for gathering insights, not all tracking is beneficial and can sometimes hurt user trust and satisfaction.

9. Use Green Hosting



Choosing the right hosting provider can have a significant impact on your website's carbon footprint:

  • Location Matters: Hosting your servers closer to your main user base reduces the distance data must travel, decreasing latency and energy use.

  • Seek Efficiency: Look for hosting providers that offer optimised server setups that consume less energy.

  • Choose Renewable Energy: Opt for hosting services that power their data centers with renewable energy, reducing the environmental impact of your hosted sites.

These focused tips will help you enhance the sustainability of your digital projects, making your website not only faster and more user-friendly but also more environmentally friendly. Read More
