Berners-Lee highlighted studies showing that half of the world population will be online by next year - but the rate of take-up was slowing considerably, potentially leaving billions cut off from government services, education and public debate.
Berners-Lee, who hatched the Web in 1989, said a sense of optimism about the internet had been damaged by abuses of personal data, online hate speech, political manipulation and the centralization of power among a small group of major tech firms. It's already amassed a wealth of supporters, including Google, Facebook, Innovation Award victor and Young Global Leader honoree Mariéme Jamme, Virgin Group founder Sir Richard Branson, and many more. In the new contract, Berners-Lee realizes he is asking a lot."Everybody is responsible going forward for making the web a better web in different ways", he said."The ad-based funding model doesn't have to work in the same way - it doesn't have to create click-bait".
Jonathan Zittrain, a law professor at Harvard University and author of The Future of the Internet and How to Stop It said: "To me, the most important function of the contract is to remind people that the web we have isn't the only one possible".
So that anyone, no matter who they are or where they live, can participate actively online.
Keep all of the internet available, all of the time so that no one is denied their right to full internet access.
So everyone can use the internet freely, safely and without fear. "If you are a social networking company you make sure that (.) you allow people to control their data". They thought 'there'll be good and bad, that is humanity, but if you connect humanity with technology, great things will happen.
So the web has rich and relevant content for everyone.
Individuals would pledge to "respect civil discourse and human dignity so that everyone feels safe and welcome online", according to one of the core principles.
Berners-Lee's contract for better internet sets principles for governments, companies and individual internet users.
Sir Tim Berners-Lee is very well known. However, as the Web increases in power, this is having the unintended effect of increasing the digital divide, Berners-Lee argued.
Giving people control over their own data will benefit everyone, Berners-Lee told CNN Business' Senior Tech Correspondent Laurie Segall in Lisbon. He claims it is the government's responsibility to see that all citizens have internet access.
"People in the big companies are concerned about truth and democracy".
"If we spend a certain amount of time using the internet we have to spend a little proportion of that time defending it, worrying about it, looking out for it..."
