Addressing Nestlé's corporate website carbon footprint

Climate change is one of society's greatest challenges. It is also one of the greatest risks to the future of our business and we are working towards net zero in our business and supply chains.

Why we care about improving the efficiency of Nestlé's digital ecosystem

To host our websites, Nestlé uses servers that consume energy to run and provide users with access to images, videos and text. Energy is also required to view and download content.

Using devices to access the internet is such a day-to-day activity, many of us don't think about the fact it generates greenhouse gas emissions. With over 70 corporate websites, changes we make to improve the energy efficiency of our digital assets can help reduce emissions.

What improvements are we making to our Nestlé corporate websites

We want to provide users with a faster and more seamless browsing experience, optimizing energy use along the way. Since 2021, we've worked to ensure any improvements to Nestlé's corporate websites use principles that take into account their footprint. This includes:

Structure & user journey

We are regularly revamping the different sections of our Nestlé corporate websites to create a more intuitive and efficient user journey. We're simplifying the navigation, creating better cross-linking, improving our internal search functionality, and improving filters. All these actions help our audiences to quickly find the information they are seeking, therefore reducing time spent on site, and ultimately, reducing energy usage. 

Optimizing content

We regularly review our website data to identify further ways of improving our content. For example:

• We take care to ensure imagery and videos used are relevant to the messaging on the page and serve a purpose.
• We aim to keep the size of PDFs as low as possible.
• By adding the relevant keywords that our users are searching for, content can be found more easily in a search engine. If our audiences spend less time searching, less energy will be required.

Compressed visuals

We are transitioning to WebP image format wherever possible. WebP is a modern image format that provides superior compression compared to traditional formats like JPEG and PNG. By using WebP we can significantly decrease file sizes, which means faster page load times and lower energy consumption for both our servers and users’ devices.

Efficient infrastructure

We use a Content Delivery Network (CDN) and we implement effective caching strategies. By storing frequently accessed resources closer to the user, we reduce the need to repeatedly fetch data from the server. This approach significantly improves page load times, minimises bandwidth usage, and lowers the energy required for each visit.

Dark mode

Dark mode provides users with the flexibility to choose between light and dark themes. Using a 'dark' mode allows users to reduce power consumption on devices with OLED or AMOLED screens. Dark mode is also more accessible and offers many users an enhanced browsing experience.

Will it affect how our audiences use our websites?

The changes we are making to reduce our digital carbon footprint will have a positive impact on SEO, accessibility and making the user journey more streamlined, so overall it should improve the user experience as well as energy use.
