Tue 2 May 2017 – Los Angeles International (LAX) and London Gatwick airports have started recycling initiatives to turn waste into either natural gas fuel or onsite energy use. In partnership with the Los Angeles Bureau of Sanitation (LASAN), LAX is beginning a 90-day pilot programme involving the collection of food waste from a targeted sample of airports restaurants and concessionaires, which will then be transported offsite for conversion into natural gas using an anaerobic digestion process. Solid and liquid organic waste that cannot be converted into methane gas will be converted into commercial-grade fertiliser. Gatwick Airport and DHL Supply Chain, meanwhile, have opened a new waste management plant, which they claim makes the airport the first in the world to turn both food and packaging waste into energy onsite.

Virgin Atlantic sees impressive gains in fuel efficiency and an 8% fall in emissions as a result of fleet changes
Tue 27 Jun 2017 – Following a slowdown in the overall fuel efficiency of its fleet in 2015, Virgin Atlantic Airways has rebounded with an impressive 8 per cent annual improvement last year, according to the airline’s latest Sustainability Report 2017. This is largely down to the positive impact of Boeing 787 aircraft entering the fleet in 2016, improved passenger load factors and other operational gains. Total CO2e aircraft emissions fell from 4.43 million tonnes in 2015 to 4.08 million tonnes in 2016, from a high of 5.22 million tonnes in 2007 when Virgin Atlantic set a target to reduce CO2 emissions by 30 per cent per revenue tonne-kilometre (RTK) by 2020. The 22 per cent reduction since 2007 is matched by a 17 per cent fall in CO2 per RTK and a 22 per cent drop in CO2 per passenger km over the past 10 years. This, says the airline, puts it well ahead of the industry’s annual fuel efficiency improvement target for the period up to 2020.
Airline fuel efficiency gains not keeping pace with rapid growth in passenger traffic and emissions, finds studies
Wed 20 Dec 2017 – Fuel efficiency gains and fleet modernisation have failed to keep pace with overall growth in aircraft carbon emissions as a result of the rapid increase in air passenger travel, finds two reports monitoring airline performance. In its annual ranking of the carbon efficiency of 200 of the world’s largest airlines that are responsible for 92 per cent of worldwide air traffic, German organisation atmosfair says global CO2 emissions increased by 4 per cent in the past year, while the kilometres flown rose by almost 7 per cent. It says airlines are only modernising their fleets at a slow pace with just 1 per cent of aircraft worldwide classified as highly fuel efficient. A study by US NGO the International Council on Clean Transportation (ICCT) found a sharp increase in passenger traffic drove up both profits and fuel consumption on US domestic airline operations between 2014 and 2016.
Atmosfair says even the best performing airline fleets emit on average 20% more CO2 per kilometre than the most fuel efficient planes operating at full capacity such as the Airbus A350-900 or Boeing 787-9. A fleet with only a medium level of efficiency in technology and operations releases twice as much carbon than the most fuel efficient aircraft. These new aircraft models, which can achieve consumption values of less than 3.5 litres of kerosene per 100 passengers, have raised the bar considerably in terms of carbon efficiency, it says.
Airlines that have not updated their fleets or have only made small improvements have lost ground in its latest 2017 ranking, notes atmosfair. The Atmosfair Airline Index is based on the CO2 emissions of an airline per passenger-kilometre flown on all routes, and calculated using the aircraft type, engines, use of winglets and seating and freight capacity, as well as occupancy. The efficiency index is intended to be used by travellers to compare airlines when planning their flight.
The highest ranking airlines in the index will therefore be those with the most modern fleets with high seating densities and high passenger and cargo loads. Differences among airlines on the same route can be substantial, says atmosfair, with fuel consumption per passenger-kilometre possibly being twice as high for one airline than for another.
UK charter airline TUI Airways (formerly Thomson Airways) once again topped the index, reaching 80% of the technically achievable optimum. Its German counterpart TUIFly ranked third, with regional carrier China West Air in second place in the overall ranking.
European and Chinese airlines performed well, says atmosfair, with South America’s LATAM ranked as the best international net carriers as a result of its modern fleet and high rate of occupancy. US carriers performed less well overall with only three – Alaska, Delta and United – making it into the top 50 airlines in the world.
For the 2015-2016 period, Alaska Airlines was also ranked by ICCT as the most fuel efficient on US domestic operations for the seventh year in a row, while the gap between it and the least efficient carrier, Virgin America, in 2016 widened slightly to 26%.
Between 2014 and 2016, ICCT calculates overall passenger-kilometres on US domestic operations rose by 10%, outstripping a 3% overall improvement in fuel efficiency, causing fuel use and CO2 emissions to jump by 7%.
“Industry-wide, demand is swamping energy efficiency improvements and emissions are spiking as a result,” said ICCT’s Naya Olmer, lead author of the study. Since 2012, the average profit margin for US domestic carriers has increased nearly six-fold thanks to lower fuel prices and higher ancillary fees, finds ICCT, and those carriers saved around $17 billion in fuel costs last year, about 20% of which was passed on to passengers in lower fares.
Around 30% of global CO2 emissions are attributable to US aircraft and the FAA projects aviation activity to increase 2-3% annually through to 2037.
“With airline profits surging, we need to explore environmental and consumer protection if the US is going to cap aviation carbon emissions from 2020, as it has committed to do,” commented Dan Rutherford, ICCT’s aviation Program Director and co-author of the study.
Said Dietrich Brockhagen, CEO of atmosfair: “Our findings show that aviation worldwide is not on track to meet the 1.5 degree or the 2 degree target for global warming. While some airlines have significantly improved their carbon efficiency by purchasing new aircraft, the pace of modernisation is not fast enough from a global standpoint.”

UK airspace improvements help NATS reduce carbon emissions but more modernisation required, it warns
Fri 23 Jun 2017 – Air navigation service provider (ANSP) NATS reports that improvements to the design of UK airspace helped save 55,900 tonnes of CO2 in 2016, worth £6.2 million ($8m) in fuel savings for airlines. In 2008, NATS became the first ANSP in the world to set an airspace environmental target and says it is currently tracking at a 5 per cent improvement on a goal to reduce air traffic management (ATM) related CO2 emissions by 10 per cent by 2020. However, warns NATS, it will become more difficult to achieve this unless further efficiencies can be delivered by modernising UK airspace. CO2 savings in the previous year were 157,000 tonnes. In its annual Responsible Business report, NATS says its campaign to increase the use of continuous descent approach (CDA) procedures by aircraft landing at UK airports resulted in an additional 32,070 quieter arrivals in 2016 over 2015.
UK aviation has managed to decouple passenger increase from carbon and noise growth, says industry report
Tue 19 Dec 2017 – UK cross-industry coalition group Sustainable Aviation (SA) says the sector has succeeded in disconnecting the growth in passenger numbers from the rate of growth in carbon and noise emissions. In its latest progress report, carbon emissions from the six airline members of the group – British Airways, easyJet, Monarch, Thomas Cook, Thomson Airways and Virgin Atlantic – increased by less than half a per cent between 2014 and 2016 despite a 9% increase in the number of passengers flown. During the same period, it reports a reduction of 12,000 people in the noise contour areas of five SA member airports. Commending the report, the UK Aviation Minister, Baroness Sugg, said sustainable growth was one of the key objectives of the government’s long-term strategy for UK aviation.
Total CO2 emissions from the five airlines in 2016 amounted to 33.6 million tonnes, a 0.2% increase since 2014 compared with a 2% in passenger revenue tonne-kilometres (RTKs). Fuel efficiency reached 0.347 litres/RTK in 2016, a 2% improvement over the two years and 13% better than 2005.
“Aviation is a UK success story. However, delivering environmentally sustainable aviation growth in the UK, with the significant economic benefits that it brings, is a challenge that our industry is ready to meet,” said SA Chair, Ian Jopson, acknowledging “there is more to do.”
Jopson, who is Head of Environment and Community Affairs at air navigation services provider NATS, stands down after a two-year tenure. Achievements made by the group and its members during that period, he said in the introduction to SA’s Sixth Progress Report, included an updated roadmap on delivering long-term carbon emission reductions from the sector, a leading contribution by UK airlines in securing global progress on the CORSIA emissions scheme and significant progress in creating a UK sustainable aviation fuels sector.
The latter had been achieved by securing the inclusion of such fuels in the government’s Renewable Transport Fuels Obligation and working with the government agency Innovate UK to form a group to bring together interested stakeholders. Jopson also noted progress on airspace modernisation following the government’s publication earlier this year of a revised UK Airspace Policy.
“The industry is committed to playing its role,” said Jopson. “However, we can’t achieve sustainable growth without the support and action of government.”
Sustainable Aviation published a report earlier this year on local air quality around airports, which found that aircraft emissions contributed just 1% of UK NOx emissions, compared to 32% from road transport, and 0.1% of PM10 emissions.
“However, we recognise the need to tackle this issue head on and we set out in that report a number of activities to further reduce the air quality impact of aviation,” said Jopson.
Noise, though, had been a priority for SA’s activities in 2016, he said. “We have made good progress against our 2013 Road-Map. However, I think it is fair to say that these benefits have not always been reflected by community perceptions. It is essential that we better understand the concerns of local communities.”
The group has commissioned independent research involving focus groups and one of the first tasks of incoming Chair, Neil Robinson, is to oversee the publication in early 2018 of a discussion paper on ways to further reduce aircraft noise.
Also in 2018, SA is to publish its vision for aviation in 2050 and the following year to update again its CO2 roadmap.
“I am delighted to be taking over as Chair at such an interesting time,” said Robinson, who is Group CSR Director at Manchester Airports Group, in the progress report. “As we prepare to enter the CORSIA scheme from 2020; the UK government develops a new Aviation Strategy, which places safe and sustainable growth at its heart; and we seek to limit global temperature rises to less than 1.5C, it has never been a more important time for Sustainable Aviation and our members.”
Speaking at the launch of the report, Baroness Sugg, the new Aviation Minister, said: “The aviation sector is one of our key industries, essential to our future prosperity and the very symbol of global Britain. But as we continue to push the boundaries of success, sustainability must remain at the heart of everything we do. I am encouraged by the actions of the aviation industry to embrace that commitment.”
