A good start would be only actual professional engineers calling themselves engineers.
There is also higher need for programmers ("developers") than for actual engineers.
Accreditation isn't just for enforcing a minimum standard of education - it's primarily so that people can actually be held responsible for bad decisions, and so that they have leverage over their bosses (it's harder to find an actual engineer or a doctor willing to do unethical things for you, when they could lose their license over it).
