2. GM’s Sustainability Strategy

3. Environmental Commitment We’re continually assessing our environmental impact and taking steps to reduce it GM has a commitment to the environment and sustainability that applies to every part of our business – from our supply chain, to product manufacturing, to the vehicles we put on the road.

4. Environment: Our Commitment We’re committed to continuous improvement as we reduce the environmental impact of our vehicles and facilities. Our culture of environmental responsibility makes us think creatively, consistently innovate, and be leaner and more efficient. Waste Reduction We strive to be the automotive industry’s waste reduction leader. Energy Efficiency We strive to reduce emissions & petroleum dependence by being more energy efficient. Resource Preservation We help preserve natural resources and enhance habitats surrounding our facilities. Greener Vehicles We’re building fuel-efficient vehicles that fit our customers’ needs and lifestyles. • GM Environmental Principles • We are committed to actions to restore and preserve the environment. • We are committed to reducing waste and pollutants, conserving resources, and recycling materials at every stage of the product lifecycle. • We will continue to participate actively in educating the public regarding environmental conservation. • We will continue to pursue vigorously the development and implementation of technologies for minimizing pollutant emissions. • We will continue to work with all governmental entities for the development of technically sound and financially responsible environmental laws and regulations. • We will continually assess the impact of our plants and products on the environment and the communities in which we live and operate with a goal of continuous improvement.

5. Why Renewable Energy?

6. We believe in harnessing the power of renewable and alternative energy and we’re one of the leading users in the manufacturing sector. RENEWABLEENERGY Landfill Gas Solar Biomass

7. Global Solar Financials – Improving

8. Global Solar Markets - Expanding

9. Cost To Install Solar Has Decreased Rapidly Average Solar Installation Cost for Historic Residential and Commercial Projects (2010$/WDC) • Total solar installation cost decreased 35% in the past five years from $8.00 to $5.20 • One of the key components of solar installation cost was solar module • Module prices decreased 69% in the past five years from $4.14 to ~$1.30

10. Manufacturing Impact • Predictable electric rates • Savings from future cost escalation “solar as hedge” • Roofing program integration • Brings value from solar incentives • Improved 25-year performance warranty • New project / economic development can contribute state and local grants • Employee involvement • Community outreach platform • Global deployment model

11. Renewable Energy Strategy & Results

12. Commitment: 125 MW of renewable energy by 2020

13. GM Solar Goal: 60MW by 2015 • Maximize solar system size at viable locations • Eco-label (Renewable Energy) all Chevrolet projects • Contribute to solar goal of 60 MW • Support 2020 goal of 125 MW renewable energy • Create value through the GM Venture investment • Create community outreach enabler Eco-Label for the 2012 Chevrolet Sonic

14. Global Solar Output • 2 of the 5 largest rooftop solar arrays in the world • Rooftop • Zaragoza, Spain 10.5 Mw • Russelsheim, Germany 9.1 Mw • Kaiserslautern, Germany 1.97 Mw & 797 Kw • Toledo, Ohio 1.8 Mw* • Baltimore, Maryland 1.23 Mw • Rancho Cucamonga, California 1 Mw • Fontana, California 910 Kw • Ground-Mounted • Detroit Hamtramck, Michigan 516 Kw • Lake Orion, Michigan 350 Kw • *When complete

15. 9 facilities with solar charging canopies • Baltimore Operations • Bowling Green Assembly • Detroit-Hamtramck Assembly • Lordstown Assembly • Parma Metal Center • Warren Technical Center • Warren Company Vehicle Operations • GM Shanghai Headquarters • Milford Proving Ground

16. Solar Power – United States • GM is the #1 solar user in the automotive sector and ranks in the top 20 of all commercial users of solar energy in the U.S.

17. US Leadership Position • GM Leads Auto OEM in US, Total Installed Capacity • GM Leads Auto OEM in US, Total Installed Systems

18. Landfill Gas • One of the largest industrial users of landfill gas in U.S. • Three plants use landfill gas • Orion Assembly 25% • Toledo Transmission 17% • Ft. Wayne Assembly 10%

19. Biomass • 15 MW of biomass-generated electricity from sugar cane for our GM de Brazil manufacturing facilities.

20. How to Overcome Barriers

21. Challenges • Varying state incentives and Renewable Portfolio Standards (RPS) • REC pricing • Current market conditions in regards to tax credit appetite • Lack of well defined Federal program • Net metering limited to few states • Full utility support in regards to distributed generation and smart grid capabilities • Initial Approval • Clear understanding of reason, including savings, incentive offsets, and value of PR • Risk assessments and tolerance • Financial Approval • Balance sheet • Plant longevity (Closures) • Technology

22. Recommendations • Line up with reputable experienced developer/supplier • Assure financing is available upfront • Involve top leadership in reason why! • Involve local management in reason why! • Stay involved with implementation • Be prepared for surprises • Plan PR carefully

23. Project Implementation • Development phase • Identify feasibility for project • Roof condition • Interconnection • Incentives • Financing • Risk Assessment • Enter Preliminary Agreement (w/ costs identified) • Enter final contract (due diligence, finalize costs/cash flows) • Design/Construction • Commission

24. Renewable Energy & Your Vehicle

25. DESIGN, BUILD & SELL THE WORLD’S BEST VEHICLES
