Aerospace is an essential part of modern life. It helps drive economic growth and prosperity; it brings the people of the world closer together. Because of the tremendous benefits aerospace provides, our industry—and our company with it—is growing.
At the same time, Boeing recognizes that climate change is a serious concern. Air transport accounts for about 2 percent of total manmade CO2 emissions. But, as our industry grows, we recognize the need to reduce its environmental impact and even to aim to move it towards zero.
Boeing’s environmental strategy is:
As a technology and innovation leader, we are improving the fuel-efficiency and environmental performance of our products for customers.
As an aerospace leader, we bring industry together to align on opportunities to improve the environment
To support the sustainable growth of commercial aviation, we are working furiously to advance commercialization of sustainable aviation biofuel.
As a responsible corporate citizen and neighbor, we are reducing energy use, greenhouse-gas emissions, pollution and waste at our facilities.
This approach supports our customers, our business, our communities and the environment
Boeing and the commercial aviation industry:
In 2008, Boeing and other stakeholders (including airlines, Airbus, Bombardier, Embraer) signed the “Aviation Industry Commitment to Sustainable Growth” with industry-wide goals including:
Improve industry-wide fuel efficiency by 1.5% annually to 2020
Achieve industry-wide net carbon-neutral growth from 2020
Reduce the industry’s net carbon emissions by 50% by 2050, compared to 2005 levels

“Sustainable Biofuel”
A comprehensive approach

5. Boeing supports “drop-in” biofuels
Meets fuel performance requirements
Requires NO change to airplanes or engines
Requires NO change to infrastructure
Can be mixed or alternated with today’s Jet-A fuel
Sustainable aviation biofuel refined through certain (hydro-treating) processes has been approved as a drop-in fuel to up to 50 percent of the jet fuel supply
Biofuel performs as well or better than Jet A made from fossil fuel (higher energy content, lower freeze point, does not absorb heat or water.)
Other options (e.g. solar, fuel cell, liquefied natural gas) won't work for aviation

6. Sustainability is Critical to Success
Key Sustainability Requirements1
Benefits
Assurance of environmental benefit
Doesn’t contribute to indirect impacts
Socio-economic
Positive GHG impact
Moral license
Biofuel production should be sustainable and socially responsible (e.g. providing socio-economic value to communities; not competing against food/water resources; not causing adverse changes in land use.
3rd party standards and audits2
Credit opportunity3
1. Other requirements include land use changes, water use, land rights, labor rights 2. Examples include RSB, ISCC, FSC, etc. 3. Examples include EU ETS avoidance and US RINs 8
