Hello Bakshara, I've built a website, which partially addresses what is described here... at the moment it's minimal version, so it doesn't calculate carbon footprint for every single item - but I was planning to build such database. If the app gets some positive responses - I will definitely work on it more...
Currently aim is to promote sustainable lifestyle and boost environmental awareness (without shaming anyone :) )
have a look at www.bumi.club
and let me know what do you think about it!
