How does it work? When you host a website on a server in a data center, it's important to remember that non-renewable energy sources usually power data centers. There is a way out of this situation - green web hosting.

However, it’s also important to remember that websites and applications can harm the environment, regardless of the chosen hosting. Developers can contribute to a more sustainable digital ecosystem by adopting green web development practices. This approach aligns with broader efforts to combat climate change and promote environmental sustainability in the technology industry.

In this article, we'll examine best practices for app development and website operations related to sustainability and the criteria of a green web hosting provider.

What is Green Web Hosting?

Green web hosting is a type of sustainable web hosting that emphasizes sustainable practices and carbon reduction. Green hosting involves using energy-efficient technologies, renewable energy sources, and environmentally friendly data centers with renewable energy certificates.

Using green web hosting minimizes the environmental impact of eco-friendly web hosting by reducing the carbon emissions generated by data centers.

Basic Principles of Green Web Hosting

Basic Principles of Green Web Hosting

  1. Using Renewable Energy. Many green hosting providers either directly use renewable energy sources, such as wind, solar, hydroelectric, or geothermal, for their data centers, or purchase renewable energy credits to offset their energy use.
  2. Energy Efficiency. Implementing energy-efficient technologies and practices is critical to green hosting. This includes using energy-efficient servers, optimizing cooling systems, and using best practices in data center design and management to minimize energy consumption.
  3. Server Virtualization. Virtualization optimizes resource utilization and reduces the number of physical servers needed by allowing multiple virtual servers to run on a single physical server. This results in lower energy consumption and a smaller environmental footprint.
  4. Eco-Friendly Policies. Green web hosting providers often adopt environmentally conscious policies and practices beyond their technical infrastructure. This may include reducing waste, recycling hardware components, using environmentally friendly office supplies, and using green products.
  5. Sustainable Infrastructure. Green hosting providers can build or retrofit their data centers with sustainable materials and technologies. This includes using energy-efficient hardware, green building materials, and implementing environmentally responsible practices.

For example, traditional hosting services may not pay as much attention to environmental sustainability and may use traditional energy sources. Green web hosting offers an alternative to reduce energy consumption, carbon emissions, and e-waste generation.

Often projects are unaware of their environmental impact and whether they use traditional or green web hosting. However, you can start with the most straightforward step - choosing a green web hosting or data center that demonstrates an informed attitude towards environmental conservation.

How to Choose Green Web Hosting

How to Choose Green Web Hosting

Data centers that are committed to sustainability can have a positive impact on the environment through the use of highly efficient strategies. You can follow these steps to find top green hosting providers:

  1. Identify web hosting providers that prioritize sustainability and offer green web hosting services. Compare their environmental commitments, energy efficiency practices, and use of renewable energy on their green hosting.
  2. Choose green web hosting providers that power their data centers with renewable energy sources such as wind, solar, or hydroelectric power.
  3. Consider the location of the data center where your website will be hosted. Choose a data center located in a region with abundant renewable energy sources.
  4. Look for green web hosting companies that use energy-efficient equipment, cooling systems, and power management technologies. Look for renewable energy certificates and sustainability metrics such as PUE (Power Usage Effectiveness).
  5. Consider vendors offering carbon offset programs to offset the carbon emissions their operations generate.

PUE can be used to define a green data center. Power Usage Effectiveness is an energy efficiency metric that measures the ratio of the total power consumed by server equipment to the net power consumed by servers. In simple terms, this indicator should be closer to 1. Thus, it is possible to talk about the energy efficiency of green data centers or green web hosting providers.

Measuring the Environmental Impact of a Website

Assessing your website's environmental impact is an essential step in implementing green practices. You can measure key metrics and then implement some sustainable practices, which will be discussed next.

The Carbon Footprint of a Website

A website's carbon footprint is the total amount of greenhouse gas emissions, specifically carbon dioxide (CO2), produced throughout its lifecycle, both directly and indirectly.

Most websites generate carbon emissions from the energy used by servers, networking equipment, and data centers to host and deliver content to users.

User interactions with a website contribute to its carbon footprint by increasing server workload and data transfer. To evaluate a website's carbon footprint, tools such as Website Carbon Calculator can be used to estimate its energy consumption.

It is worth noting that such tools also consider a site's use of green hosting services and improve the overall score when they are disclosed.

Server Power Consumption

Modern server equipment is designed to be more energy-efficient. It features low-power processors and advanced power management capabilities.

Additionally, efficient resource allocation and workload management techniques, such as server virtualization and load balancing, help minimize idle capacity and reduce power consumption. Data centers require cooling systems to maintain optimal temperature and humidity levels, which can account for a significant portion of overall power consumption.

Working with green web hosting allows you to reduce these emissions.

PageLoad Time

Longer page load times require more server resources and processing power to generate and deliver content to users' devices. This increased server activity can lead to higher energy consumption.

Loading and rendering web pages with complex layouts, large files, or excessive scripting can cause users' devices to consume more energy, impacting, for example, battery life.

Image and Video Optimization

Images and videos are essential to websites, but they can significantly impact the environment if not optimized correctly. Large image and video files require more bandwidth and server resources to transfer and load.

By implementing responsive design techniques, websites can serve appropriately sized images and videos based on the user's device characteristics, such as screen size and resolution.

Techniques of Sustainable Web Design, Development and Management

Here are some fundamental green online project practices to remember when building apps, websites, and services.

Green Practices in Design

Green Practices in Design

Sustainable web design is an approach to web development that puts people and the planet first. It ensures that digital products, services, and data are created in accordance with the principles of the Sustainable Web Design Manifesto: clean, efficient, open, honest, regenerative, and sustainable.

  1. Create a user-friendly and easy-to-use interface. By default, selecting the lightest and least functional version reduces emissions from passive browsing. Non-essential information disappears from the screen and reappears when needed, reducing the time visitors spend on their devices trying to complete tasks or find information.
  2. Avoid overabundance of media assets. Decorative design should only be used to enhance user interaction, and unnecessary assets should be removed. A page with fewer heavy elements will likely load within three seconds.
  3. Ensure that the navigation is well structured. A well-organized site structure improves search engine indexing and helps visitors find content quickly. Navigation errors waste visitors' time and may cause them to leave the site. Check for broken or outdated links and correct them using redirects.
  4. Optimize browser caching. Browser caching reduces the need to constantly reload files from the server and can even allow offline browsing, providing both resilience and performance benefits.
  5. Use recognizable patterns. Recognizable design components can help visitors find information quickly, reducing the time spent on your website and lowering emissions.
  6. Use a more sustainable approach to images. Optimize and compress images. Provide lazy loading so that image assets are loaded only when needed. The same applies to sound, video, and animation files. This will speed up page load times and benefit users and the environment.
  7. Use system fonts. Reducing the number of downloaded fonts can decrease renderings and reduce the carbon footprint. Displaying non-system fonts per element requires energy, so using fewer fonts can help reduce energy consumption.

Sustainable Code Tips

Sustainable Code Tips

Green web development involves building web services and applications to minimize their environmental impact. Following sustainability best practices, programming teams can increase productivity, reduce data, and reduce pollution. In addition to the practices listed below, we recommend ensuring your project is hosted and developed on a green web hosting service.

  1. Minimize HTML, CSS, and JavaScript. The whitespace in code has no value when presented to a visitor. Using minification saves valuable data, which reduces loading time. When a page loads quickly, visitors are less likely to interrupt their use of your resource or look for information elsewhere.
  2. Use code separation in projects. Small, modular components allow for optimized caching and loading only necessary code functions, reducing the payload. This ensures that unused parts of the resource remain unloaded, potentially resulting in significant savings.
  3. Apply Tree Shaking to the code. Tree Shaking techniques automatically remove obsolete workflows and files simultaneously, reducing file size and lowering download costs and potential processing time.
  4. Avoid code duplication. Do not hesitate to simplify or remove code to focus on core functions and produce a cleaner, less redundant product. It is better to improve existing code rather than building from scratch. Avoiding repetitive code reduces markup loss and server power consumption.
  5. Implement asynchronous code and prioritized loading. To avoid FOUC (Flash Of Unstyled Content), it is recommended to defer or set all external assets to async mode unless they are required at boot time. If they are required, ensure they are prioritized correctly. This can help older devices and devices with lower battery capacity access your applications more efficiently. It is vital to prioritize processing power.
  6. Utilize useful JavaScript and its API. Removing distracting elements that cannot be viewed, such as those identified by the Page Visibility API, can reduce unnecessary visual effects processing, such as animations, in the background. Utilizing modern APIs or low-code solutions can often decrease the reliance on a bulky code base.
  7. Make sure your scripts are secure. Check the code for vulnerabilities, exploits, header issues, and code injection to ensure a secure infrastructure. A secure infrastructure is less likely to be compromised, which can lead to massive amounts of data being stolen and destroyed. You can also perform regular security audits on your server.
  8. Use the latest stable language version. Upgrading to newer language versions can improve efficiency, reduce data center power consumption, and increase download speeds. Additionally, older versions may have security issues that can harm your application.

Eco-Friendly Project Management

Eco-Friendly Project Management

Green project management refers to the practice of integrating environmentally sustainable principles and practices into a project, including several of these:

  1. Consider using CDNs and Edge Cache. Edge caching and Content Delivery Networks can optimize the delivery of your site's traffic by keeping servers closer to the end user, reducing page load times.
  2. Choose green web hosting. Choose a company that mitigates the environmental impact of the website. Green hosting will help identify resource overruns, reduce the environmental impact of equipment, and mitigate the impact associated with the production of consumed electricity. You can also tell your website visitors that you use green web hosting and add widgets displaying your carbon footprint.
  3. Document and share project results. Easy-to-understand formats should be used to present results generated during the project. This will allow for the reuse of these results, reducing the computer time and energy needed for future iterations and resulting in lower emissions.
  4. Utilize automated systems. Design planning systems that include environmental criteria can help scale digital sustainability across the enterprise. This can reduce code redundancy and other benefits, leading to a decrease in energy consumption and negative impact.
  5. Evaluate the third-party services you use. Evaluate plugins, widgets, feeds, maps, and other third-party services for environmental impact, and use them as little as possible to reduce the product's overall environmental impact. For example, large CSS libraries and JavaScript frameworks should only be used if no alternative exists.
  6. Create a mobile version of the product. Mobile interfaces and adaptive design can reduce energy consumption by increasing productivity and simplifying the visitor experience. Additionally, smaller devices often have lower power consumption.
  7. Test compatibility each release cycle. Prioritize compatibility across devices to adhere to sustainability principles. This reduces e-waste, especially for users who prefer not to upgrade frequently or use older devices.


Companies that choose green web hosting can enhance their image and demonstrate their commitment to sustainability. In addition, some regions and industries have regulations related to energy efficiency and carbon emissions, and green hosting can help companies meet these requirements.

A clear sustainability statement on your website and internally can make aligning policies and adopting sustainable practices easier. And by incorporating it early into your digital product strategy, you can reap the benefits of increased efficiency and reduced environmental impact.

By choosing green web hosting, such as eco-friendly VPS and dedicated servers for business, you can reduce your energy consumption, lower your carbon footprint, and promote responsible IT resource management.

We recommend that you be responsible for your server hardware and keep it and your project running on it as long as possible. This will reduce your own costs for changing hardware and green hosting providers and follow the principles of sustainable development.
