Environment Variables

Adi and Valeria return to discuss the latest news from The Week in Green Software. They explore whether sustainability can be built directly into the software development process, from identifying “energy smells” in code to using tools that make energy efficiency as visible as performance or security. They also tackle the growing debate around AI’s environmental impact, examining whether today’s resource-intensive investments can be justified by future benefits, and why better measurement of energy, carbon, and water use is essential for making informed decisions about technology’s role in a sustainable future.
