Low carbon technologies in a green economy - Energy and Climate Change Contents


Memorandum submitted by Sustainable Aviation

1. INTRODUCTION

  1.1 Sustainable Aviation (SA) is a long term strategy which sets out the collective approach of UK aviation to tackling the challenge of ensuring a sustainable future for our industry. A world-first, Sustainable Aviation was launched in 2005 and brings together the UK's leading airlines, airports, aerospace manufacturers and air navigation service providers.

  1.2 Signatories to the SA Strategy are committed to delivering significant reductions in the UK aviation industry's carbon dioxide emissions, nitrogen oxide emissions and aircraft noise over the next 40 years and beyond.

  1.3 SA establishes mechanisms for monitoring and regular reporting of progress towards a range of specific objectives. Our Strategy sets out the industry's vision for a sustainable future through a series of seven goals and 30 commitments, relating to economic, environmental and social aspects of aviation. Specifically in relation to climate change, these include:

    — Limiting climate change impact by improving fuel efficiency and CO2 emissions for new aircraft by 50% per seat kilometre by 2020 compared with 2000 levels.

    — Reducing nitrogen oxide (NOx) emissions by 80% over the same period.

    — Establishing a common system for the reporting of total CO2 emissions and fleet fuel efficiency, and pressing for aviation's inclusion in the EU emissions trading scheme at the earliest possible date.

  1.5 We have established a governance structure to ensure implementation and communication of the Strategy. This comprises a pan-industry, high-level Sustainable Aviation Council and a Working Group, supported by a series of sub-groups.

  1.6 Signatories to Sustainable Aviation include:

    Airlines: British Air Transport Association (BATA); British Airways; bmi; Virgin Atlantic; FlyBe; Monarch; easyJet; Thomas Cook; Thomson Airways

    Airports: Airport Operators Association (AOA); BAA; Manchester Airports Group (MAG), Newcastle, Birmingham International, Peel Group, Belfast City, Leeds Bradford, London City, Infratil Airports, Bristol International

    Manufacturers: Society of British Aerospace Companies (SBAC); Airbus; BAe Systems; Cobham; Doncasters; FAC; GKN; Marshall Aerospace; Messier Dowty; QinetiQ; Rolls-Royce; Bombardier

    Air Navigation Service Provider: NATS

  1.7  We published our first Progress Report in 2006, and a second in 2009 (the Executive Summary is attached at Section 9) and will continue to deliver on the goals and commitments identified in the strategy, as well as promoting our work both within the UK and internationally.

  1.8  Sustainable Aviation supports the initiatives being taken at a global level by the aviation industry, most recently illustrated by the proposals at the UN Climate Change Summit in New York on 22 September.

  1.9  We also include at Section 9 a copy of the letter we have written to the Secretaries of State for Transport, and Energy & Climate Change, in response to the Committee on Climate Change's letter of 9 September 2009. We believe our response forms the basis for a pragmatic manifesto for real progress to be made at the Copenhagen climate summit in December.

2. SUMMARY

  2.1 SA's submission to the Committee responds to the specific questions posed. We then explore more fully the developments to which the UK aviation industry is committed and we are happy to have the opportunity to provide further explanation to the Committee in October. In brief, we would like to highlight the following points:

    — Aviation is a global industry and solutions to the industry's environmental impact must be secured at international/global level.

    — CO2 emissions from international aviation should be included in a post-Kyoto global climate change agreement through a global sectoral approach, or deal, under which they would be treated as an indivisible sector total and not apportioned to individual States.

    — Emerging technologies will achieve significant longterm reductions in the environmental impact of flying.

    — SA's Roadmap illustrates our confidence that CO2 emissions can be curbed to 2000 levels by 2050 notwithstanding growth as forecast in passenger (and therefore flight) numbers.

    — SA manufacturing signatories continue to invest heavily in research and development to improve fuel-efficiency of new aircraft, and to reduce noise and emissions; SA airline signatories continue to upgrade their fleets and streamline their operations; SA airports are working collaboratively with the airline and air traffic communities to develop and deliver ground-based operational improvements to reduce emissions; and NATS, the UK's air navigation service provider, is the first in the world to have set targets to reduce air traffic management-related CO2.

    — Collectively, the industry has committed to meeting challenging targets for CO2, NOx and noise set by ACARE. These targets are shared between improvements in engine (15-20%), airframe (20-25%), operations and air traffic management (5-10%). Putting a price on carbon within a cap and trade system would ensure net emissions will not rise. However, current levels of R&D investment by industry and government are inconsistent with having sufficient, mature technology to deliver against these demanding targets.

    — Aviation is a great success story for the UK and requires no funding from the public purse. The industry is investing significantly in researching solutions to its environmental impact, which should be both recognised and encouraged by Government.

3. RESPONSES TO THE COMMITTEE'S QUESTIONS

3.1 What opportunities exist for the creation of a green new deal whilst pursuing a low carbon economy? Which technologies have the greatest potential? Has the Government done enough in its stimulus package?

  3.1.1 Engine and airframe developments, together with second-generation biofuels, offer the greatest long-term potential for reducing aviation-related CO2. In the shorter term, air traffic management offers environmental efficiencies through new tools enabling improved procedures and more efficient use of airspace. Airports are working with airlines, on-airport businesses, and passengers to influence further carbon reductions; for instance, on-site renewable energy, and fixed electrical ground power (FEGP) to aircraft, which removes the need to run aircraft power units whilst on the ground.

  3.1.2 The Government's stimulus package must recognise the importance of R&D in identifying opportunities for a "green new deal" and provide incentives for long term investment in R&D programmes.

3.2 How realistic are the Committee on Climate Change's projections for the use of different types of new technologies? What is needed to achieve the development and deployment of them?

  3.2.1 The Committee's report on Aviation is due to be published in December 2009. It will consider UK aviation demand and emissions, improving the carbon efficiency of aircraft, use of biofuels and hydrogen, and elements of a global deal.

  3.2.2 We welcome the Committee's recognition of the importance of carbon trading and the need for a global sectoral deal for aviation. That global deal must encompass emissions from all international aviation, to avoid competitive distortion, avoid creating a patchwork of conflicting and potentially overlapping national and regional policies, and avoid "carbon leakage".

  3.2.3 The global deal should cover only the CO2 emissions from aircraft, consistent with ICAO's recommendation, recognising both the uncertainty in scientific knowledge and the difficulties in characterising the non-CO2 climate effects of aircraft at altitude. Policy to address non-CO2 climate effects should be developed and implemented, separately, when there is a clear scientific basis for doing so.

  3.2.4 We also welcome the committees recognition that a significant increase in investment in R&D will be required if the targets are to be met.

3.3 What are the most important drivers, nationally and internationally, for a low carbon economy in the UK? To what extent do the outcomes of the international negotiations at Copenhagen matter?

  3.3.1 Aviation is a global industry with operating standards set and coordinated internationally, through the International Civil Aviation Organisation (ICAO). The UK is part of a global network, contributing a significant percentage of aircraft into the core of Europe, not only through local European traffic, but also because of its unique position as Europe's primary North Atlantic gateway. The efficient transfer of aircraft from one country to another can fundamentally affect the capacity of the system so it is vitally important that we work cross-border if we are to achieve the synergies which will deliver environmental benefit. The sustainable growth of aviation underpins the future growth of the UK economy; maintaining our competitiveness is why a global deal on aviation is so important.

  3.3.2 It is fundamentally important to have a globally agreed deal on aviation emissions; the current patchwork of regionally based emissions schemes will lead to inappropriate outcomes, notably carbon leakage.

  3.3.3 The global deal should be based on global targets, and full and open emissions trading; incentivise airlines to purchase low-carbon aviation fuels that offer net carbon reductions over their full life cycle; and require Governments to establish the right legal and fiscal frameworks to facilitate and increase investment in the research and development of new technology designs for aircraft and aircraft engines, development of low carbon sustainable alternative fuels, and longer term options such as improvements in airspace management.

  3.3.4 Under the global deal Governments should ensure that any revenues from economic measures should be clearly earmarked for environmental purposes. UNFCCC countries meeting in Copenhagen should give ICAO a clear mandate and timetable for developing and implementing the detail of such an approach

3.4 How important is it to the UK economy that it becomes a leading developer and exporter of low carbon technologies? What Government policy needs to be in place to do this?

  3.4.1 The CBI's report Pulling Ahead: Innovating for Low-Carbon Leadership, published in early September, calls for the Government to maintain and improve the research and development tax credit scheme, which encourages investment, to help Britain lead the way in low-carbon innovation. It identifies various sectors where the UK already leads in low-carbon technology, including Rolls-Royce's Environmentally Friendly Engine initiative (see Section 7 below).

  3.4.2 The UK model for reducing CO2 emissions related to air traffic management is the first of its kind in the world and NATS is looking to export its methodologies in order to spread the benefit.

  3.4.3 The UK already derives significant export income from aerospace products and components. If the UK technology base does not keep these products competitive against increased pressure for carbon reduction, the major airframers will be forced to procure such products elsewhere, or else UK industry will locate elsewhere to maintain competitive advantage.

3.5 Are we seeing impacts of a downturn in demand on investment in low carbon technologies? If so, how can this be addressed given the need to meet long term targets? What obstacles to investment are there?

  3.5.1 Reducing fuel burn also reduces costs significantly so the long-term incentive to find solutions remains high and commitment to long term solutions remains embedded. However, there is no doubt that the current recession is straining business models and investment will increasingly be under scrutiny regarding its ability to deliver.

  3.5.2 Even with the recession, airlines are still investing in new technology and SA member airlines have between them placed orders for more than 80 A380 and Boeing 787 aircraft. These aircraft represent the next generation in their category of aircraft. Recession will drive a reduction in capacity, but many airlines are choosing to achieve this by retiring older aircraft, rather than cancelling orders for new aircraft.

4.  THE SA ROADMAP

  4.1  In 2008 SA undertook an exercise to develop a projection to 2050 for emissions of CO2 from UK aviation, taking into account improvements in operational efficiency, new technology, and a partial fuel substitution from sustainable sources.

  4.2  SA has projected that emissions of CO2 from UK aviation will rise until 2020 but will then level off and fall to current levels or below by 2050. Importantly the projection does not take into account the wider CO2 reductions in other sectors that will be achieved through airlines' participation in Emissions Trading. The projection relies critically on the current and forward investments by both industry and government, on the success of the various technology programmes and their incorporation into aircraft fleets.

Note: This emissions forecast is based on DfT forecast of demand published in November 2007 and actuals up to 2005. UK aviation CO2 emissions actually fell in 2007 and 2008 and are expected to decline further in 2009.

5. BIOFUEL TECHNOLOGY

  5.1 SA's Strategy contains a commitment to "review periodically the potential and practicalities of alternative fuels to aviation kerosene". Since that was published in 2005 considerable progress has been made in evaluating and testing alternatives to traditional crude-oil derived kerosene, to the extent that this commitment is currently being reviewed and will be made more challenging going forward.

  5.2 Sustainably produced, lower carbon fuels must offer aviation a "drop in" alternative to conventional fossil-fuel based kerosene. They are not without their challenges—new fuels must meet stringent international standards for commercial jet fuel, production of feedstocks and refining capacity must be scaled up, and globally-recognised sustainability standards must be adhered to—but the potential environmental and energy security benefits are considerable.

  5.3 SA members including Virgin Atlantic, British Airways, Airbus and Rolls-Royce have already participated in several programmes to test the potential of lower carbon alternative fuels including the first "proof of concept" flight in 2008 which was the culmination of months of detailed laboratory and engine rig testing.

  5.4 It is generally recognised that viable mass alternatives to a liquid hydrocarbon fuel for commercial aviation are still some years away. However, their technical certification is proceeding rapidly, and it is expected that "drop in" biofuel/kerosene blends will enter the normal jet fuel supply chain within the next few years. The SA Roadmap offers a conservative assessment that 20% of fuel for UK departing flights would come from sustainable alternative sources by 2030, contributing to a 10% cut in absolute CO2 emissions.

  5.5 Through internationally recognised bodies such as the Roundtable on Sustainable Biofuels (RSB), which includes expert NGOs, academics, fuel suppliers and customers, common sustainability standards can be developed at a global level. SA members are also committed to supporting only the development of fuels which meet a set of strict sustainability criteria.

  5.6 International mechanisms will need to be developed to account for their usage and to allow for flexibility within the aviation biofuel supply chain. Revenues from EU ETS and other environmental economic instruments could go into sustainable biofuel feedstock cultivation and developing processing or refining capacity, to provide a lower carbon alternative for aviation and other transportation sectors. As there are limited, if any, technology alternatives to fuel-powered jet engines in the 2050 timeframe, priority should be given to providing the appropriate regulatory and economic frameworks and incentives to allow rapid implementation of sustainable biofuels in the aviation sector. We would be concerned, however, about negative unintended consequences associated with mandatory targets on UK or EU-departing airlines.

  5.7 SA recognises that biofuels do not represent a "silver bullet" for aviation's contribution to climate change. We do believe they can offer an opportunity for significant reduction in the carbon intensity of air travel for our passengers.

6. AIRFRAME DEVELOPMENTS

  6.1 The Airbus A380 entered service in 2007 and is redefining the environmental performance of large civil aircraft. The UK industry has an important role in the design and manufacture of this aircraft, including production of the wings and landing gear.

  6.2 The A380 produces 10% less NOx per seat and burns 12% less fuel per seat than other large aircraft currently in operation, requiring less than 3 litres of fuel per seat per 100km in a standard cabin configuration. The A380 has an efficient structure that incorporates more new material than any other jetliner currently in service, with composite and other lightweight materials accounting for more than 25% of its structure. The A380 also benefits from the latest innovations in aerodynamics, reducing drag to the minimum and improving fuel efficiency further.

  6.3 The A350 XWB (Xtra Wide-Body) is Airbus' response to market demand for a medium capacity long range wide-body family and is planned to enter service within the next five years. The A350 XWB confronts the challenges of fuel economy, rising passenger expectations and increasing environmental concerns.

  6.4 The A350 XWB has the most efficient structure in terms of design concept, with an airframe made of more than 60% new materials, chosen for their superior weight and strength properties. This design also allows weight savings via optimum fibre lay-up and skin thickness tailored to the requirements of the location. Excellent aerodynamics, together with advanced high lift devices and advanced systems contribute to greater fuel economy.

7. ENGINE TECHNOLOGY

  7.1 Rolls-Royce has made significant progress towards meeting the challenging fuel-efficiency and NOx reduction targets set by ACARE and endorsed by SA. This progress, coupled with a commitment to current and planned research and technology programmes (such as the Environmentally Friendly Engine programme, EFE), provides visibility of the industry's commitment to meeting the reduction levels specified in the ACARE targets. Options being considered for future narrow bodied aircraft carry different noise and fuel efficiency benefits

  7.2 EFE is a five year, £95 million UK-funded programme, started in 2006, aimed at delivering significant reductions in CO2 and NOx emissions. Rolls-Royce is leading the consortium of five UK aerospace companies and six universities.

  7.3 EFE will produce and run a gas turbine core that will be tested in a new, specially modified test-bed at Bristol. The test programme, consisting of four different engine builds, will allow the technology to be progressively developed, tested and validated. This approach enables advanced technologies to be incorporated into new commercial products in a short time frame with reduced risk.

  7.4 More recently, Rolls-Royce has been awarded the 4-year, low-carbon research package SILOET (Strategic Investment in LOw-carbon Engine Technologies), with £45 million of Government funding, which will develop, low weight, low carbon and low emissions technologies for future engines.

8. AIR TRAFFIC MANAGEMENT

  8.1 Air traffic control relies heavily on advanced communication, surveillance and navigation technology to ensure the safe and efficient movement of aircraft. It requires significant ongoing investment in research and development of tools, systems and procedures to improve service, and to improve environmental efficiency by enabling aircraft to fly closer to their optimum profile, minimise interaction with other traffic flows and regulate speeds and level changes.

  8.2 Innovations recently introduced or due on stream in the short-term include Precision Area Navigation (P-RNAV); arrivals and departure management tools; iFACTS (including 4D trajectory management); Oceanic airspace management tools; airport ground operations information tools (A-CDM);

  8.3 Overall, NATS believes that 2% of its 10% target to reduce ATM-related CO2 by 2020 will be delivered by new tools and technologies. On conservative estimates, this could equate to some 520,000 tonnes of ATM CO2.

  8.4 Based on today's fleet composition and today's fuel prices this would equate to an approximate £50 million saving in fuel so there is a long-term cost incentive, as well as environmental incentive, to continue investment and this is supported by the airlines. The Arrivals Manager tool alone has the potential to save as much as 300,000 tonnes of CO2 per annum—equivalent to 2,000 B747 transatlantic flights.

  8.5 NATS has already achieved significant fuel savings by enabling shorter routes through military airspace when this is not in use. The close cooperation to achieve this "flexible use of airspace" is now established and will increase in the future. Wider airspace design and re-design is also critical to maximum efficiency and therefore environmental improvement; NATS has an ongoing programme to achieve route systems which accommodate the optimum flight profile of different aircraft and to reduce noise over the ground.
