That's the intent of AB 370, a bill introduced earlier this year by Al Muratsuchi, a former state prosecutor who was elected to the California Assembly in November 2012.
"This bill would require an operator to disclose whether or not it honors a request from a consumer to disable online tracking," reads the draft legislation. "The bill would also require an operator to disclose if it does not allow third parties to conduct online tracking on the commercial Web site or online service."

The proposed legislation sounds a rare note of clarity in the contentious debate surrounding do-not-track proposals, asking website operators simply: Do you honor consumers' do-not-track requests?
Working with the World Wide Web (W3C) Consortium, the advertising industry, browser developers and privacy advocates were already supposed to have developed a global Do Not Track standard, as was proposed last year in President Obama's Consumer Privacy Bill of Rights.
But the DNT standards work stalled in November 2012, prompting advertisers and marketers to focus again on self-regulation, after Microsoft enabled DNT by default in Internet Explorer 10. The Association of National Advertisers (ANA) reacted with outrage, as did some technology backers of the developing DNT standard, with the ANA's president and CEO playing the emotional card and expressing his "profound disappointment" at Microsoft's move.
Advertisers' subsequent inability to seal a DNT deal, however, didn't endear them to some members of the Senate Commerce Committee, which Wednesday held "a status update on the development of voluntary do-not-track standards."
Luigi Mastria, managing director of the Digital Advertising Alliance (DAA), told the committee that his group, in conjunction with numerous other advertising and marketing industry groups, had already created "a one-button choice mechanism to stop the collection and use of Web viewing data" for consumers. The advertising industry has long argued against DNT, saying that it would compromise the ability of sites to offer content to consumers without making them pay for it.
But Sen. Jay Rockefeller (D-WV), the committee chairman, said the one-button choice mechanism wasn't enough, and called on all players to honor the DNT standards work to which they'd committed. "It's now April 2013 and consumers are still waiting for these do-not-track standards," Rockefeller said, reported USA Today. "I believe these companies are dragging their feet."
Rockefeller, who's due to retire from Congress at the end of 2014, in February introduced the Do-Not-Track Online Act of 2013. He introduced an earlier version of the bill two years ago but didn't push the bill through the Senate after the advertising industry said it would develop a DNT standard.
Rockefeller's bill calls for the development of a DNT standard and penalties for any businesses that don't abide by it. "I do not believe that companies with business models based on the collection and monetization of personal information will voluntarily stop those practices if it negatively impacts their profit margins," he said at the committee hearing, reported Associated Press.
But not everyone thinks that a legal solution would work. "Generally speaking, when it comes to privacy protection, we should avoid placing excessive faith in schemes like Do Not Track because they could fail, just as previous techno-fixes failed to keep pace with fast-moving developments in this space," Adam Thierer, senior research fellow at the Mercatus Center at George Mason University, told the committee. Instead, he noted that concerned consumers can already safeguard their privacy using a number of free tools, including HTTPS Everywhere and VPN services.
"If our fear is that consumers lack enough information to make smart privacy choices, then let's work harder to educate them while pushing for greater transparency about online data collection practices," said Thierer. "Finally, we should remember that not everyone shares the same privacy sensitivities and that citizens also care about other values, such as cost, convenience, and choice."
