1. Sustainability An Airline Perspective

2. By the Numbers

3. Sustainability
Sustainability is a natural evolution from Delta’s corporate culture, history, and existing policies and programs:
Delta’s Rules of the Road: “minimize our impact on the environment”
Delta Code of Ethics: “be a responsible global citizen”
SkyTeam Corporate Social Responsibility Statement
Delta Environment and Carbon Emissions Policies
In addition, there is increasing pressure from external stakeholders, including investors, customers, partners, and external ratings agencies, for transparency and beyond-compliance performance.
Goals
Be a positive force for local and global change
Improve external reporting
Implement Climate Change Work Plan
Engage employees, customers, and supply chain
Governance
Corporate Leadership Team
Executive Environmental Leadership Council

4. Sustainability Strategy
Stakeholder Expectations
Delta’s stakeholders expect Delta to produce sustainable financial results, invest in healthy communities, maintain a robust workforce, and protect natural environments. Collectively, these expectations drive Delta’s approach to sustainability and social responsibility.
Delta’s Vision: Defining Sustainability
Delta defines Corporate Sustainability as meeting the company’s financial goals of growth and profitability over time through innovative business practices that minimize the environmental impacts of our operations and promote the health, welfare and productivity of the individuals and communities we serve and employ.
Delta’s Key Stakeholders
Delta’s sustainability strategy and action plan are targeted at understanding and exceeding the expectations of six key stakeholder groups:
Investors
Customers
Employees
Government & Industry
Communities
Supply Chain

7. Reducing GHG Emissions a global sectoral solution under ICAO
The industry has coalesced around three industry-wide aircraft emission mitigation goals:
1.5% annual fuel efficiency improvements through 2020
Carbon neutral growth at 2020 (CNG 2020)
50% reduction in CO2 emissions by 2050, relative to 2005 levels
And a four-pillar approach to achieve the goals:
Technology enhancements
Operational efficiency improvements
Infrastructure improvements
Positive economic measures
Climate change policy should unlock the greatest sources of emissions reductions from aviation, at the lowest cost, first
Achieve the most economical emission reductions in the air transportation system first, especially those that pay for themselves through efficiency improvements
Recognize the inherently low margins within the airline business and be designed to allow the industry to continue to invest for the future
Commercial aviation generates 2-3% of global CO2 emissions
Commercial aviation needs to address:
criticism of its contribution to climate change
economic threat of duplicative emissions charges

8. Commercial Aviation’s 4-Pillar Approach technology enhancements
Aircraft retirement and fleet renewal
300 aircraft on order. Newer aircraft are up to 25% more fuel efficient than the older aircraft that they replace
Challenges: expensive and limited by technology available
Investment in existing fleet
Winglets
Removal of unnecessary weight
Maintenance
Engine compressor washes
Increased vigilance of pressure leaks & flight control rigging
Biofuels
Delta adheres to 7 biofuel principles that address sustainability, performance, and economics. Our Trainer, PA refinery allows us to explore biofuel opportunities, although price remains a major hurdle.
To carry an item on a commercial flight requires about 4% of its weight in fuel each hour.

9. Delta’s Fuel Council tracks the impact of these initiatives.
Commercial Aviation’s 4-Pillar Approach operational efficiency improvements
Flight planning
Taxi procedures
Take-off procedures
Slower cruise speeds
High-speed tractors
Reduced APU usage
Continuous descent arrivals (OPDs)
Schedule adjustments
Delta’s Fuel Council tracks the impact of these initiatives.

10. Commercial Aviation’s 4-Pillar Approach infrastructure improvements
Antiquated air traffic management systems increase flight times and fuel burn
NextGen
Single European Sky
Funding for these initiatives has lagged
Budgetary politics
Airlines reluctant to invest without government commitment

11. Commercial Aviation’s 4-Pillar Approach positive economic instruments
Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA): global market-based measure administered by ICAO
Carbon management strategy to:
access carbon markets
address carbon constraints
Reinvest in aviation and the environment
Overlapping carbon taxes, surcharges, and trading schemes can result in multiple payments on the same emissions.

12. Climate Change GHG Emissions
Aircraft Fuel Efficiency
Efficiency per revenue ton mile has improved 5.8% since 2009; projected to improve 12.6% for period
Efficiency per available seat mile has improved 5.6% since 2009; projected to improve 12.1% for period
Factors affecting aircraft fuel efficiency:
Gauge
Stage length
Seat density
Amenities & fuel-savings initiatives
GHG Emissions
98.8% from aircraft; remainder from:
Delta “owned” facilities: 0.7%
Airports: 0.3%
GSE: 0.2%
Emissions have declined over
6 million tonnes (13%) since 2005
Lower capacity
Improved fuel efficiency
Higher load factors
Carbon-neutral growth since 2012 through purchase of voluntary offsets

13. Cross-divisional Involvement in environmental sustainability
Operations
Pilots observe fuel-conservation practices and monitor APU usage
Flight attendants voluntarily recycle in- flight trash
Mechanics maintain aircraft trim & reduce water and chemical use during maintenance
Ground personnel follow procedures to avoid spills and minimize waste
