TSXV: CST 
Outstanding shares: 79,687,836

QUÉBEC CITY, May 21, 2013 /PRNewswire/  - CO[2] Solutions Inc. (TSXV: CST)  is 
pleased to  announce  that it  has  renewed until  March  31, 2015  its  Joint 
Development Agreement (JDA)  with Codexis,  Inc. ("Codexis")  to continue  the 
development and  deployment  of  CO[2]  Solutions'  enzymatic  carbon  capture 
technology.

Under the amended  and restated  JDA, CO[2]  Solutions' proprietary  enzymatic 
method for the  efficient capture  of carbon  dioxide from  power plants,  oil 
production operations and other  large sources of  emissions will continue  to 
benefit  from  Codexis'  directed  enzyme  evolution  technology  and   enzyme 
production capabilities. CO[2] Solutions' technology uses the natural  enzyme, 
carbonic anhydrase, to enhance the efficiency of CO[2] capture from industrial
emission sources, at lower cost  than conventional carbon capture  technology. 
Codexis'  technology  has  dramatically  improved  this  enzyme's  ability  to 
function in  harsh  industrial  conditions.  Carbonic  anhydrase  provided  by 
Codexis  is  now  suitable  for  pilot  and  demonstration  testing  in   CO[2 
]Solutions' carbon capture  projects. Carbonic anhydrase  is found in  humans 
and other living  organisms and  is critical  in the  efficient management  of 
CO[2] during respiration.

Commenting on the agreement, Evan Price, President and CEO of CO[2]  Solutions 
remarked, "We are  pleased to extend  our agreement with  Codexis. With  this 
continued collaboration, CO[2] Solutions intends to continue to capitalize  on 
the opportunities that it affords to  help bring this technology to the  North 
American and  global  markets  and  provide  a  solution  for  the  efficient, 
large‐scale mitigation of greenhouse gas emissions, including CO[2] Solutions'
recently announced project in the Alberta oil sands."
