It also tells you the amount of trees you should plant to offset the web page's carbon footprint.

# or
yarn dev

Open http://localhost:3000 with your browser to see the result.

You can start editing the page by modifying pages/index.js. The page auto-updates as you edit the file.

• parsers/data/carbon-intensity.csv is supplied from ourworldindata.org, which is based on bp statistical review of world energy 2022, 71st edition
• data/variables.json contains static calculation variables used in the calculator tool

Variable metrics;

CARBON_PER_KB // g
