Making our online presence more eco-friendly

Welcome back to part two of our Sustainably Digital series. Last time, we talked about why  being digitally eco-conscious is so important, and in this article, we’ll explore practical strategies we can take right now to reduce our digital carbon footprint. 

Stop streaming so much video 

Ever considered the carbon cost of your Netflix binges? Shockingly, platforms like Netflix churn out roughly 24.9 billion grams of carbon every year from website visits alone. 

When it comes to hosting video content on your website, ditch the autoplay. Not only does it reduce data usage, but it’s a win for accessibility too.  

Shrink image sizes, not quality 

Images are often a website’s heaviest component, consuming energy with every pixel loaded. The more images you use and the larger the file size, the more data is transferred, resulting in increased energy consumption. 

Optimise image sizes and formats to reduce data transfer, and compress them using a tool or plugin like TinyPNG or Smush to reduce weight without sacrificing quality. Also, WebP format lossless images are roughly 26% smaller in size than PNGs, and 25-34% smaller than comparable JPEG images at equivalent SSIM quality index. With optimised images, your pages will be lighter (and therefore better for the planet) but will also load quicker, leading to happier end users.  

Email with intention   

We’re not saying you need to abandon emails completely, but there are ways to cut down and be more sustainable. Regularly declutter your inbox and delete unnecessary junk. We’re all guilty of sending an email but forgetting to attach the thing we said we’d attach, so ensure you triple-check your drafts before you hit that send button to minimise follow-ups. 

Also, unsubscribe from newsletters you never read – not only is it beneficial for the planet, but your wallet will thank you too!

Delete unused or outdated content 

Bulky websites aren’t great for your user, let alone the environment. Think about your existing content – does that blog from 2010 still serve a purpose? If not, update it, merge it, or retire it entirely. Fewer pages mean fewer server requests, lower data transfer, and a cleaner, greener web presence overall. 


Embrace minimalist design  

Less really is more, especially when it comes to sustainable design. Opt for fewer widgets, simpler layouts, and cleaner elements. Not only does this benefit sustainability, but it’s also usually better visually too.  

Sustainable coding

The code that powers your website can also be written with sustainability in mind. Well-structured, efficient code minimises energy usage, helping your site run smoothly with less environmental impact.  

Sustainable coding practices include: 

  • Efficient algorithms and data structures: Writing code that utilises efficient algorithms and data structures can significantly reduce computational resources. 
  • Energy-efficient coding patterns: Adopting coding patterns that prioritise energy efficiency can reduce the overall energy consumption of software applications. 
  • Minimising network requests: Combining resources, implementing caching strategies, and reducing unnecessary data transfers.  


Boost your SEO 

Ensuring your website is optimised for search will ensure your users can find relevant content quickly, without the need for unnecessary browsing.
