Developing a greener software relies on several focuses. There is no perfect methodology at the moment, but still, you can start following these steps:

- Sustainability - This means the software has to be created reliable, lifelong and efficient to fulfill the users' needs it is made for and, if possible, trying to aim at sustainable goals.

- Frugality - Do not develop complex architectures for simple projects. Also build reliable structures if the solution is made to last and grow. It takes more time to build things twice rather than building one structure in the first place. Simplify your code as much as possible. Always design your solution the best way to reduce your carbon footprint.

- Methodology revamp - Waterfall and Agile methodologies are the most popular at the moment. Waterfall model is definitely very energy consuming (much work can be deployed for nothing, for instance), and Agile methodologies are flexible but can create extra work or additional tasks that could be merged. The solution is simple: to save time and energy, work and design your projects before going through. It will save steps and help all stakeholders see your vision.

- Testing optimization - Testing is practically one of the longest steps in software development. To save time and energy, prefer automated tests solution for large scales phases and use human brains for simple testing before using an entire infrastructure!

- Smart monitoring - Deploy easy monitoring solutions or track your energy consumption yourself to make sure the software you maintain is on track.

By applying all these tips, you will also save money!

If you do not have time or resources to do this yourself (we know, it takes a lot of time!), go for software development agencies. You have the choice between:

• Eco-design oriented software agencies
• Agencies with teams locally-based (always better because supposedly, local agencies ensure better project management and resource saving by coordination)
