Rights groups, including the UK's Open Rights Group (ORG) and European Digital Rights (EDRi), have made a last-minute push to encourage citizens to contact their European representatives and demand that they enshrine an open internet through single market regulation.
The ORG and EDRi warned in April that time was running out to "prevent vested interests from controlling the free flow of information", adding that rights were about to be lost under the heel of business.
The groups said at the time that the final stages of discussions would involve a "trialogue" between the European Commission, the European Parliament and the Council on the Telecommunications Single Market Regulation to discuss the internet and its flow.
They warned that new rules would "create paid fast lanes, allow price discrimination in the EU, and authorise the blocking of lawful content".
Now, in a final push the ORG said that the European Parliament should return to the plans adopted in 2013 and preserve net neutrality.
"Net neutrality creates an open marketplace. When big ISPs want to change the rules, you have to be suspicious. They are in a powerful position to abuse their role, which is why the European Parliament needs to stand firm," said ORG executive director Jim Killock.
"The European Council doesn't even say the words 'net neutrality' in its latest proposals, which show how far we have come from the positive declaration of the European Parliament that would have seen net neutrality enshrined in law.
"If companies can buy their way to a faster internet, it will stifle creativity and threaten the openness of the internet."
Citizens are asked to contact their MEP, and an information site called Save the Internet in Europe has been launched to support the campaign.
Already supporting local net neutrality is World Wide Web creator Tim Berners-Lee (pictured), who made his own statements on the subject earlier this year.
"Some companies and governments are arguing that we should depart from the principle of net neutrality," he said.
"Until now, we've largely got along OK without explicit laws to protect net neutrality, but as the internet evolves the situation has changed. If we don't explicitly outlaw this, we hand immense power to telcos and online service operators."
