- Much of web performance optimization overlaps with sustainable web development practices – especially when it comes to reducing the amount of data transferred on a site and implementing performance budgets to prevent regressions.
- The biggest impact web perf experts can make with regards to sustainability involves non-technical actions:
- learning about sustainable software practices
- raising awareness for the topic
- helping to determine what not to build and what to delete
- taking the entire lifespan of data products into consideration
- While currently measuring the carbon impact of websites relies on proxy metrics and rough estimations, we still should still observe them and investigate problems.
- We need better metrics and APIs to better estimate emissions due to device use and embodied carbon.
