The things we eat, the items we buy, how we choose to get around, and the services we use all have a social and environmental impact. Making sustainable choices now will shape a better future for those that follow.
The way we build websites should also be sustainable. Each web page we publish requires a certain amount of energy to serve, and this energy has a carbon footprint associated with it. ‘Heavy’ pages served from fossil fuel-powered data centres produce more CO2, whereas ‘light’ pages served from data centres powered by renewable energy produce much less CO2.

For small websites such as this, the impact of these carbon emissions is negligible. But for large websites that receive millions of hits every day the numbers are significant; a web page with a carbon footprint of just 0.16g per view and 10 million monthly visitors would produce the equivalent of 19,408.59kg of CO2, about as much CO2 as boiling water for 2,629,890 cups of tea.

Therefore in accordance with the Sustainable Web Manifesto I pledge to do the following:
- Ensure the services I provide and use will be powered by renewable energy
- Ensure the products and services I provide will use the least amount of energy and material resources possible
- Ensure the products and services I provide will be accessible, allow for the open exchange of information, and allow users to control their data
- Ensure the products and services I provide will not mislead or exploit users in their design or content
- Ensure the products and services I provide will support an economy that nourishes people and planet
- Ensure the products and services I provide will function in the times and places where people need them most
