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.

US domestic aviation emissions could increase 33-50% by 2030 as a result of Trump climate withdrawal
Tue 27 Jun 2017 – Although there has been recent speculation over the possibility of the United States not joining the voluntary phase of ICAO’s CORSIA carbon offsetting scheme as a result of President Trump’s decision to withdraw from the Paris climate agreement, there are other implications for global aviation emissions. Pledges made by countries under the agreement must take into account reductions in domestic aviation emissions, which are not covered by CORSIA. Globally, domestic aviation emissions make up around 38 per cent of all aviation emissions, with the US responsible for nearly a half. According to research by Manchester Metropolitan University’s Centre for Aviation, Transport and the Environment (CATE), US domestic aviation emissions could rise by 33 to 50 per cent over 2005 levels if the US does not carry out its CO2 reduction plans and so heavily impact the sector’s overall emissions.
Fri 1 June 2018 – The business aviation sector has come together to raise awareness and encourage adoption by business aircraft owners, operators and fuel suppliers of sustainable alternative jet fuels (SJAF).
Heathrow announces investment in its first peatland restoration project as part of carbon neutrality target
Mon 24 Sept 2018 – As part of plans to be carbon neutral by 2020, Heathrow Airport is to invest £94,000 ($124,000) in a peatland restoration pilot project in the north-west of England.
Fri 30 Nov 2018 – With just a month to go before airlines and business aircraft operators with international flights must start monitoring and reporting their CO2 emissions under the CORSIA carbon offsetting scheme, the sector says it is firmly on track to meet its commitments.
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.”

LanzaTech’s low-carbon jet fuel ready for take-off as Virgin Atlantic plans for first commercial flight in October
Fri 14 Sept 2018 – Virgin Atlantic will undertake a passenger flight in October using for the first time low-carbon fuel produced through its partnership with LanzaTech. This follows a decision by members of the fuel standards body ASTM in April to include alcohol-to-jet synthetic paraffinic kerosene (ATJ-SPK) produced from ethanol as an approved blending component of conventional jet fuel for commercial flights.
