Page size (also called page weight) refers to the overall size of a particular web page. A page size includes all of the files that are used to create the web page. These files include the HTML document, any included images, style sheets, scripts, and other media

Page load time is the time it takes to download and display the entire content of a web page in the browser window (measured in seconds).

HTTP requests happen when a web browser sends a “request” to your website’s server for information on a webpage. When a user visits a page on your website, your server heeds this request and returns the files contained on that page to the user’s browser. The fewer HTTP requests a website has to make, the faster the site can load.

“GHG footprint” is the total amount of greenhouse gases (GHG’s) impacting the environment produced both directly and indirectly due to various human activities, expressed in equivalent tons of carbon dioxide.

Everything we use, wear, buy, sell and eat takes water to make.

The water footprint measures the amount of water used to produce each of the goods and services we use. It can be measured for a single process, such as growing rice, for a product, such as a pair of jeans, for the fuel we put in our car, or for an entire multi-national company. The water footprint can also tell us how much water is being consumed by a particular country – or globally – in a specific river basin or from an aquifer.
