Sustainable IT Playbook for Technology Leaders

By: Niklas Sundberg

Overview of this book

We are at a critical point in human history. Humanity is under threat, but all is not lost. We can take action! But how? Sustainable IT Playbook for Technology Leaders will show you how. It will walk you through the construction and implementation of a sustainable IT strategy and enable you to do your bit for the future of mankind. The book is split into three parts. Part I details the “why” and the clear and present danger that humanity faces today: the climate crisis. How did we get here, what are the immediate threats, what are the planetary boundaries that we need to peel back to safe levels, and what impact does IT have on society at large? Part II will focus on the "what.” It examines the nitty-gritty details of what we can do to unlock significant returns on sustainable investments toward a more sustainable future. Part III, the final part of the book, focuses on the “how.” How do you turn your ideas into action? What do you need to do to establish your baseline and your direction of travel towards your objective? This part provides tangible case studies and explains how you can start your journey today to begin delivering global and impactful objectives. By the end of this book, you’ll be able to plan, implement, and communicate a sustainable IT strategy and set yourself apart as a progressive technology leader.

Sustainable software development

In the early days of software development, memory resources and processing power was scarce, and each line of code had to be carefully considered. This changed rapidly, though. As we saw in Chapter 1, Our Most Significant Challenge Ahead, based on Moore’s law principle, the number of transistors in a dense integrated circuit (IC) has doubled roughly every 2 years since the 1970s. Due to this development, the need to write memory and process efficient code shifted to increase software engineering productivity and produce faster programs. As the sentiment is now changing toward becoming more sustainable, carbon-efficient, and energy-efficient, software development has a vital role in this journey.

To conserve battery time, especially mobile phone end users tend to turn off resource-intense applications, and there is a constant demand for manufacturers to produce more battery-efficient products. The demand is not from the software community...
