If you're curious where all the parts that comprise the device you're reading this on came from, download SourceMap. It's a new mapping website that allows you to trace where products come from and what the carbon footprint therein is, another way to help reduce it.
The website traces products by splitting it into components then tracing each individual component from its origin to your home.
It also sometimes includes descriptions of companies where the components are from. Many of the maps even offer a carbon footprint figure, for the environmentally conscious among you.
Products of all sorts, from laptops to Nutella hazelnut spread, can be traced.
The site's main purpose is to encourage companies to be more transparent about where their products come from, and features such as "item-level traceability," in which you could scan an item in a store and find its entire history instantly, are on their way.
