Confirms Outstanding Performance and Environmental Benefits of Amyris's Renewable Diesel Under Real-World Driving Conditions

EMERYVILLE, Calif., June 29, 2015 -- Amyris, Inc.

(Nasdaq:AMRS), the industrial bioscience company, today announced the
successful completion of a diesel demonstration program with Volkswagen of
America, Inc. that was designed to test the commercial readiness of Amyris
renewable diesel and its ability to enhance VW's innovative and advanced
diesel technology. The collaboration included evaluating emissions
reductions and demonstrating performance of Volkswagen's existing TDI(R)
Clean Diesel technology using advanced renewable diesel fuel.

Utilizing vehicles provided by VW in real-world driving conditions, the
two-year-long program to assess the results reinforced the company's data
that greenhouse gas (GHG) emissions were reduced by more than 60 percent on
a well-to-wheel basis when using Amyris's No Compromise(R) renewable diesel.
In addition, the program demonstrated fuel economy that was similar to or
improved over petroleum-based fuels, together while maintaining outstanding
engine performance under a variety of conditions.

"The results of this program provide additional validation for renewable
fuels and showcase the tremendous market potential for Amyris's advanced
renewable diesel," said John Melo, President & CEO of Amyris. "Growing
awareness of these benefits contributes to increased consumer awareness,
end-user demand pull and future adoption of renewable fuels at a larger
scale."
