		<summary type="html">&lt;p&gt;Add outline for carbon.txt&lt;/p&gt;
&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;{{FormatInfo&lt;br /&gt;
|formattype=electronic&lt;br /&gt;
|subcat=Web&lt;br /&gt;
|extensions={{ext|txt}}&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
== Overview ==&lt;br /&gt;
&lt;br /&gt;
'''carbon.txt''' is a proposed web standard for making it possible to verify that web-infrastructure uses green power, in lieu of green power, users of the standard will simply be able to see what type of power is being used by a hosting provider. The standard is designed to be chained from web-site to host to electricity provider, creating a graph of dependencies. A graph-like approach enables hosting-providers with other upstream hosting dependencies to link to those, and likewise, until an electricity provider is located.&lt;br /&gt;
&lt;br /&gt;
== File format example ==&lt;br /&gt;
&lt;br /&gt;
Via [https://github.com/thegreenwebfoundation/carbon.txt/blob/13468fed5ad3c6ea0eb372cb8523464e6b1f11f6/carbon.sample.simple.txt carbon.txt simple example].&lt;br /&gt;
&lt;br /&gt;
We assume a filename-based identification: &amp;lt;tt&amp;gt;carbon.txt&amp;lt;/tt&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Content may look as follows:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pre language=&amp;quot;ini&amp;quot;&amp;gt;&lt;br /&gt;
# we assume most sites have one main provider which might provide the servers &lt;br /&gt;
# used to serve content. If you know this, you can look up that provider's &lt;br /&gt;
# carbon.txt file to make it possible to start walking the graph.&lt;br /&gt;
&lt;br /&gt;
[Upstream Providers]&lt;br /&gt;
&lt;br /&gt;
# while a website might rely on a single provider, it's common to rely on other &lt;br /&gt;
# providers: google for analytics, or another CDN, and so on. Let's assume a &lt;br /&gt;
# simple site is hosted just by one org for this example.&lt;br /&gt;
&lt;br /&gt;
providers = [&amp;lt;URL for company&amp;gt;]&lt;br /&gt;
&lt;br /&gt;
# That's all you need&lt;br /&gt;
&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
