Could The Oil Producers & Refiners make Diesel Safe so we can continue using it ?

Certain methods can make diesel or biofuels cleaner and there is other research in engine design which could also make it better/more efficient as well.
"Diesel and gasoline fuel sources both bring unique assets and liabilities to powering internal combustion engines.
But what if an engine could be programmed to harvest the best properties of both fuel sources at once, on the fly, by blending the fuels within the combustion chamber itself?
The answer, based on tests by the University of Wisconsin–Madison engine research group headed by Rolf Reitz, would be a diesel engine that produces significantly lower pollutant emissions than conventional engines, with an average of 20 percent greater fuel efficiency as well.
These dramatic results came from a novel technique Reitz describes as “fast-response fuel blending,” in which an engine’s fuel injection is programmed to produce the optimal gasoline-diesel mix based on real-time operating conditions."
"Development of the blending strategy was guided by advanced computer simulation models. These computer predictions were then put to the test using a Caterpillar heavy-duty diesel engine at the Engine Research Center. The results were “really exciting,” confirming the predicted benefits of blended fuel combustion.
The best results achieved 53 percent thermal efficiency in the experimental test engine This efficiency exceeds even the most efficient diesel engine currently in the world — a massive turbocharged two-stroke used in the maritime shipping industry, which has 50 percent thermal efficiency.
“For a small engine to even approach these massive engine efficiencies is remarkable,” Reitz says. “Even more striking, the blending strategy could also be applied to automotive gasoline engines, which usually average a much lower 25 percent thermal efficiency. Here, the potential for fuel economy improvement would even be larger than in diesel truck engines.”
"The big-picture implications for reduced oil consumption are even more compelling, Reitz says. The United States consumes about 21 million barrels of oil per day, about 65 percent (13.5 million barrels) of which is used in transportation. If this new blended fuel process could convert both diesel and gasoline engines to 53 percent thermal efficiency from current levels, the nation could reduce oil consumption by 4 million barrels per day, or one-third of all oil destined for transportation.
“That’s roughly the amount that we import from the Persian Gulf,” says Reitz."
"Bosch, the private German technology group with €78bn in revenue last year, said it had achieved a breakthrough that “drastically” cut nitrogen oxide emissions for diesel engines.
The world’s largest car parts supplier, at its annual meeting on Wednesday in Renningen, promised to end the death-of-diesel debate with new technology to cut NOx by “10 times lower than limits set for 2020”.
“There’s a future for diesel,” said Volkmar Denner, chief executive. “Soon, emissions will no longer be an issue.”
With improvements in fuel-injection technology, better air management systems and intelligent temperature management, Bosch said engines using its new solutions could achieve average NOx readings of just 13 milligrams per kilometre in real world conditions, versus a 120mg limit for regulations coming into force in 2020."
"Plasma assisted engines fuel efficient, cleaner
Gasoline, diesel, and turbine engines could soon burn cleaner or be more fuel efficient through the application of Plasma Assisted Combustion, a technology originated and developed at Los Alamos National Laboratory, and now poised to enter the marketplace."

It is safer than gasoline now, with less CO2 give off than gas, could it be made safer may be?

Diesel is safe , its the unleaded fuels that are the killers

Safe in what respect?
If you're talking about emissions, a lot of work has already been done on this, google "tier 4 diesel"
They are still "dirtier" than gas engines in terms of particulates, but they are roughly 30% more efficient than gas in terms of fuel used.

Not any more then it is now- engine designers would have to do that.
