These data centres consume a large amount of electrical energy to run the Information Communication Technology (ICT) devices and for its cooling, as a result of that emission of $$CO:2$$ and Greenhouse Gas (GHG) has increased largely. This paper proposes a Sustainable Software Development Life Cycle (SDLC) Model. This model would contribute towards making the cloud computing systems more energy efficient and the ICT a green and sustainable development ecosystem. The Green Cloud Computing will be considered as an implementation platform for the proposed Sustainable SDLC. It is proposed that reusable, modular and cloud-shared development approach be used to make the software development and the software more energy efficient. The SDLC will use a cloud repository which will be accessible as per software development organizations cloud deployment model. © Springer Nature Singapore Pte Ltd. 2018Book Chapter
