Our 2015 Sustainability Goals

10

2010 Footprint Goals• Hold total energy flat with 1990 levels - currently down 6%.• 10% energy from renewable sources at cost competitive with best

available fossil fuels - currently at 5%.

2015 Footprint Goals• Greenhouse Gas Emissions: Reduce additional 15% from base

year 2004.• Water Conservation: Reduce water consumption 30% at global

sites that are located where the renewable freshwater supply is either scarce or stressed, based on United Nations analysis.

• Fleet Fuel Efficiency: Ensure that 100% of our off-site fleet of cars and light trucks employ leading technologies for fuel efficiency and fossil fuel alternatives.

• Air Carcinogens: Reduce 50% from a base year of 2004. • Independent Verification: Ensure that 100% of our sites are ISO

14000 certified.

2015 Market-Facing GoalsEnvironmentally Smart Market Opportunities from R&D Efforts:Double our investment in R&D programs with direct, quantifiable environmental benefits for our customers and consumers along our value chains.

Products that Reduce Greenhouse Gas Emissions: Increase our annual revenues by at least $2 billion from products that create energy efficiency and/or significant greenhouse gas emissions reductions.

Revenues from Non-Depletable Resources: Nearly double revenues from non-depletable resources to at least $8 billion.

Products that Protect People: Introduce at least 1,000 new products or services that help make people safer globally.

Cellulosic Feedstocks for Industrial Chemicals and Biofuels: The Fundamental Problem

Knowledge of the process state is poor.

There is a significant need for improved bioprocess analytical tools.

17

Bioprocess Problems from the Chemical Industry ViewpointFermentation is a difficult process to control

Enzyme optimization during saccharification is difficult

Separations are difficult and expensive

Yields and rates are poor

Consortia formed, or being formed, in Europe to address these

measurement problems.

Doesn’t optical spectroscopy address these measurement

problems?

Examples of Demonstrated, Uncommon, PAT Technologies

2-Dimensional Fluorescence• Gene expression control

Dielectric Spectroscopy• Total viable cell mass

Proton Transfer Reaction Mass Spectroscopy• Gene expression control

Virtually unknown and unused in the U.S.

Establishment of Model Reactors • Reproducible

• Value for development of control strategies

• Safe

• Use for base development of PAT

Fermentation• Gene expression

• Inclusion bodies
