Designing and building low-carbon websites independently
Speakers: Nick Lewis

Summary

What are low-carbon websites and what do they look like in practice? In this conversation, we will talk about creativity within the constraints, how to navigate client conversations when they want resource-heavy designs and how to think about your project’s carbon budget. As a bonus, we’ll get sneak peeks on what happens behind the scenes of a curation site of over 270 low carbon sites and why some of them get removed over time.

Key Insights

  • Nick Lewis entered digital sustainability motivated by personal outdoor experiences highlighting climate impact.

  • Around 2017, digital sustainability resources were limited, sparking Nick’s self-driven research and experimentation.

  • Working in traditional creative agencies, Nick found tension between flashy, heavy designs and sustainable/performance goals.

  • Transitioning to agencies with sustainability core values and then freelancing allowed Nick to work with more aligned clients.

  • Low carbon web design involves optimizing everything from typography and color choices to reducing unnecessary animations and videos.

  • Creative constraints in sustainable design often inspire innovative solutions rather than limiting creativity.

  • The Low Carbon Showcase website enforces a strict review process but has removed about 70 previously included sites as their sustainability regressed.

  • Most performance and sustainability issues on websites come from heavy videos, large images, excessive JavaScript, and multiple font files.

  • Nick is critical of generative AI in creative fields, viewing it as uncreative and energy-wasteful, but sees other AI applications as valuable.

  • Nick developed a Figma plugin prototype to help designers identify sustainability issues early in the design process without disrupting workflow.
