Air New Zealand and Boeing announce sustainable jatropha biofuel test flight

Air New Zealand and Boeing today announced Dec. 3 as the date for the airline's sustainable biofuels flight from Auckland using a 747-400 jetliner. Conducted in partnership with Rolls-Royce and UOP, a Honeywell company, one of the airplane's four Rolls-Royce RB211 engines will be powered in part using advanced generation biofuels derived from jatropha. Air New Zealand now becomes the first airline to use a commercially viable biofuel sourced using sustainability best practices.

Boeing, Air New Zealand and UOP have worked diligently with growers and project developer Terasol Energy to identify sustainable jatropha in adequate quantities to conduct thorough preflight testing. Using proprietary UOP fuel processing technology, the jatropha crude oil was successfully converted to biojet fuel, marking the world's first large-scale production run of a commercially viable and sustainable biofuel for aviation use.

"This flight strongly supports our efforts to be the world's most environmentally responsible airline," said Air New Zealand Chief Executive Officer Rob Fyfe. "We recently demonstrated the fuel and environmental gains that can be achieved through advanced operational procedures using Boeing 777s. We're also modernizing our fleet as we await our Trent 1000-powered 787-9 Dreamliners, which will burn 20 percent less fuel than the planes they replace. Introducing a new generation of sustainable fuels is the next logical step in our efforts to further save fuel and reduce aircraft emissions."

As part of the fuel verification process, UK-based engine maker Rolls-Royce's technical team conducted extensive laboratory testing to ensure compatibility with today's jet engine components and to validate the fuel meets stringent performance criteria for aviation fuel.
"In preparation for Air New Zealand's test flight we achieved our near-term goal - identifying and sourcing the first large-scale run of sustainable biofuel for commercial aviation," said Boeing Commercial Airplane's Managing Director of Environmental Strategy Billy Glover. "The processing technology exists today, and based on results we've seen, it's highly encouraging that this fuel not only met but exceeded three key criteria for the next generation of jet fuel: higher than expected jet fuel yields, very low freeze point and good energy density," Glover explained. "That tells us we're on the right path to certification and commercial availability."

Because of the unique environment in which aviation operates, stringent criteria are in place to ensure that any alternative fuel meets or exceeds current jet fuel requirements. Advance testing for the Air New Zealand flight showed that the jatropha-based biofuel met all critical specifications, including a freeze point at -53 degrees Fahrenheit (-47 degrees Celsius) and a flash point at 100 degrees Fahrenheit (38 degrees Celsius).

"Laboratory testing showed the final blend had excellent properties, meeting and in many cases exceeding the stringent technical requirements for fuels used in civil and defense aircraft," said Chris Lewis, Rolls-Royce company specialist for fuels. "The blended fuel therefore meets the essential requirement of being a 'drop-in' fuel, meaning its properties will be virtually indistinguishable from conventional fuel, Jet A1, which is used in commercial aviation today."
To process the jatropha crude, the team relied on UOP's green jet fuel processing technology based on hydroprocessing methodologies that are commonly used to produce transportation fuels. During processing, hydrogen is added to remove oxygen from the biomass, resulting in a bio-derived jet fuel that can be used as a petroleum replacement for commercial aviation. Boeing is working with airlines and engine manufacturers to gather biofuel performance data as part of the industry's efforts to revise the current American Society for Testing and Materials (ASTM) standards to include fuels from sustainable plant sources. Jatropha, which can be grown in a broad range of conditions, produces seeds that contain inedible lipid oil that is extracted and used to produce fuel. Each seed produces 30 to 40 percent of its mass in oil. Plant oil used to create the fuel for the Air New Zealand flight was sourced from nonarable lands in India and Southeastern Africa (Malawi, Mozambique and Tanzania).

Air New Zealand is one of several air carriers working to diversify and secure its energy future through participation in the Sustainable Aviation Fuel Users Group. That effort includes a commitment to sustainability criteria for fuel sourcing and commercializing plant-based fuels that perform as well as, or better than, kerosene-based fuel but with a smaller carbon lifecycle. The goal is to create a portfolio of next-generation biofuels that can be blended with traditional kerosene fuel (Jet A) to improve environmental performance.

Additional flight specifics will be announced closer to the actual flight date.

Richest 10% create bigger ecological footprint

The richest 10 percent of Canadians create a bigger ecological footprint – a whopping 66 percent higher – than the average Canadian household, says a new study by the Canadian Centre for Policy Alternatives (CCPA).

The study, Size Matters: Canada’s Ecological Footprint, By Income, is the first Canadian study to link national income and consumption patterns with global warming.

“When we look at where the environmental impact of human activity comes from, we see that size really does matter,” says Hugh Mackenzie, CCPA research associate. “Higher-income Canadians create a much bigger footprint than poorer Canadians.”

Among the study’s findings:

The richest 10% of Canadian households create an ecological footprint of 12.4 hectares per capita – nearly two-and-a-half times that of the poorest 10%.
While the size of an individual’s ecological footprint increases as household income increases, the real jump is at that top 10% level. When it comes to environmental impact, it really is a case of the rich and the rest of us.

The bottom 60% of Canadian households’ ecological footprint is below the national average but even the lowest-income Canadians create an ecological footprint that is several times the average for those in poorer nations.

“All Canadians share responsibility for global warming,” says co-author Rick Smith, executive director of Environmental Defence. “But wealthier Canadians are leaving behind a disproportionately larger footprint – and should be expected to make a disproportionate contribution to its reduction.”

Mackenzie says the study contains lessons for policy makers: “Clearly ecological impact is stongly related to income. Greenhouse gas emissions policies should reflect that reality or risk being less effective and unfair to low- and middle-class Canadians.”

Swedish SEKAB will introduce the world's first verified sustainable ethanol

Swedish SEKAB announced this week that it is the first company in the world to supply verified sustainable ethanol. The ethanol comes specifically from Brazilian sugar cane and is verified for its environmental, social, and climate perspectives.

The criteria are in line with demands highlighted in the ongoing processes being led by organisations like the UN, EU, ILO and a number of NGOs. The requirements assure that the ethanol isn’t produced using child labor, slave labor or destruction of the rain forests. Other requirements are directed at wages, working conditions, and labor laws.

In terms of the climate, the demands will result in a reduction of carbon dioxide emissions from farming, production and transport by at least 85 per cent compared with gasoline.
An independent international verification company will audit all production units twice a year to ensure the established criteria are met.

"The first harvest of sugarcane for verified sustainable ethanol has just begun," explains Anders Fredriksson. "Over 100 000 Swedish owners of E85 cars can begin filling up with verified sustainable ethanol in August."

Greendex, a sustainable consumption index

You've read the news—everyone wants to be green now. But do you really know how your personal choices are adding up? What about the choices of your fellow citizens? How well are people around the globe adopting behaviors that can make the world a more environmentally sustainable place?

National Geographic and the international polling firm GlobeScan have just conducted a study measuring and monitoring consumer progress toward environmentally sustainable consumption in 14 countries around the world.

Why? We wanted to give people a better idea of how consumers in different countries are doing in taking action to preserve our planet by tracking, reporting, and promoting environmentally sustainable consumption and citizen behavior.

This quantitative consumer study of 14,000 consumers in a total of 14 countries asked about such behavior as energy use and conservation, transportation choices, food sources, the relative use of green products versus traditional products, attitudes towards the environment and sustainability, and knowledge of environmental issues. A group of international experts helped us determine the behaviors that were most critical to investigate.

The result: the National Geographic/GlobeScan "Consumer Greendex," a scientifically derived sustainable consumption index of actual consumer behavior and material lifestyles across 14 countries. The Greendex will be tracked over time and will be comparable across the selection of countries representing both the developed and developing world.

To provide context for the Greendex results, we developed a "Market Basket," an index of actual consumption in four areas important to environmentally sustainable behavior—energy, transportation, travel, and consumer goods. A Market Basket for each country was assembled using a set of independently collected macroeconomic indicators, gathered by the Economist Intelligence Unit, which mirror, in part, the consumer behavior measured by the Greendex survey. The purpose of the Market Basket is to provide an external estimate of the results of changes in consumer behavior over time. The Greendex, for example, measures things consumers are doing to save energy in a country; the Market Basket measures whether total energy consumption in the country is actually going up or down. The Market Basket will also establish a framework for comparing the relative environmental impact of each country's size and rate of growth, over time.
