Why CCC’s Growth Should Still Continue Strategic Initiatives continue to be implemented for growth opportunities Activated Carbon and Reactivation capacity expansion in order to meet growing demand R&D investment for new product development continues Operating Expense as a percentage of revenue should decline, improving leverage of overhead expense Business development activities continue to focus on identifying and evaluating: Industry consolidation opportunities Adjacent technologies

Short-Term Initiatives To Improve Performance Align product distribution to highest profit producers Calgon Carbon Japan support team Global unification through management reorganization Product Rationalization Push Price Reduce Coal Costs

Activated Carbon and Reactivation Capacity Expansion In Order To Meet Growing Demand Optimize production of existing plants Additional 30MM lbs. GAC or 70MM lbs. PAC by end of 2012 Increase virgin GAC availability through customer conversions from virgin GAC to reactivated carbon Capacity improvement projects at existing facilities Recently announced $13MM capacity expansion to be completed in 2012 Completed plans for new production line

FLUEPAC® products in use at 18 plants (>9,000 MW generating capacity)Developed enhanced performance products over two years 22 successful full-scale trials at power plants in 2011 18 additional trials possible in 2012 4 additional trials scheduled for 2012 R&D Investment For New Product Development Continues

R&D Investment For New Product Development Continues (cont’d) New products reduce customer cost Expected carbon injection rates 50 - 70% lower than alternative products Fewer deliveries = lower transportation costs and inventory Lower particulate loading to ESP/baghouse Less PAC in fly ash: Improves ability to sell fly ash Awarded $8MM contract 11/11

2012 Sales Growth Opportunities Opportunity Location Timing New Reactivation Capacity Belgium, China, U.S. Q2 12 – 58MM lbs. on-line Expected New Reactivation Contracts Phoenix, AZ Q2 12 Disinfection By-products U.S. Q1 - Q4 12 for LT2 – Phase 1 and 2 Control of Cryptosporidium U.S. Q1 - Q4 12 for LT2 – Phase 1 and 2 Ballast Water Treatment Global Q1 - Q4 12 – New Builds/Retrofits (early adopters) Drinking Water & Wastewater Treatment Korea and China Q2 12 – 4MM lbs.

Recent Business Development Activities Industry Consolidation Q4 11: Acquired assets of idled reactivation facility Price - $2.7MM Capacity – 13MM lbs. Estimated startup – 2013 Adjacent Technologies Q2 11: Awarded $1.35MM grant to develop and manufacture domestic source of activated carbon for ultracapacitor energy storage market CCC long-term goal: Develop activated carbons for ultracapacitor storage that are technically and economically superior to existing products

Conclusion Performance Improvement should occur Proven track record of growth and improved financial performance Strategic Plan in place and is expected to continue to drive improved performance Numerous short- and long-term growth opportunities Stringent capital return hurdles and expense management
