    Why did your airport decide to become accredited at Level 1?

    The decision of El Dorado International Airport is based on its commitment to sustainable development, efficiency in the use of resources and prevention of pollution. With this accreditation, El Dorado seeks to strengthen synergies and structure alliances with the internal and external interest groups, in order to offer first level infrastructure, services of the highest quality and operational efficiency. All this, addressed to comply with recognized international standards such as the Equator Principles, also to satisfy the goals established by the UNFCCC - COP21.

    What benefits does accreditation bring to your airport?

    Accreditation at level 1 strengthens the positioning of El Dorado as an airport with an integral and professional management that has as reference the most demanding international standards to measure its results.

    The international recognition of the airport in terms of its infrastructure and the experience offered is complemented by the accreditation that places it at the forefront of sustainable management in Colombia and in the region, improving its image and reputation with its stakeholders, users and the community.

    This accreditation is also the evidence of our commitment to greenhouse gas reduction and to all the obligations acquired with the banks that financed the construction of the project.

    What would you recommend to other airports that are developing their carbon footprint?

    The main recommendation is to promote a straightforward commitment of senior management to sustainability. In this way, this strategic approach can be transmitted to all stakeholders of the organization. Therefore, it is feasible to develop and implement clear policies regarding the efficient use of resources and the management of their social and environmental impact.

    Furthermore, it is advisable to carry out benchmarking studies with other airports that have been accredited and that can be a guide to establish objectives, processes and realistic expectations from the early stages.

    What are your future carbon management plans?
    • Improve ongoing activities in terms of efficiency.
    • Promote voluntary reforestation projects of native species with our strategic partners.
    • Reach a recycle rate of 63% of the solid waste generated by the Airport for 2020.

    Why did your airport decide to become accredited at Level 2 Reduction?

    Accreditation at level 2 Reduction furthers Los Angeles World Airports’ (LAWA) goal for Van Nuys airport to become a greener, cleaner and more efficient general aviation airport. This effort helps LAWA align with the City of Los Angele’s citywide sustainability goals and initiatives. Due to existing constraints at the airport, such as staffing and data availability, level 2 is an ambitious but achievable objective.

    Describe up to 4 key projects you implemented to reduce your emissions?
    • Alternative fuel vehicles: The airport replaced old fleet vehicles with electric vehicles and other clean, alternative fuel vehicles and installed electric vehicle chargers. Currently, 49% of the airport fleet is alternative fuelled, 13% of which is electric. There are also eight publicly accessible EV chargers.
    • Building energy use: The airport participated in the Save Energy LA campaign in Summer 2016 by encouraging employees at the airport to turn off lights and unplug devices when not in use. LAWA produced a monthly environmental newsletter that provides employees with energy conservation tips and reminders.
    • Green Business certifications: Due to LAWA’s conservation efforts in energy use, all LAWA offices at Van Nuys have earned green business certifications from the Los Angeles Green Business Program.
    What benefits does accreditation bring to your airport?

    The accreditation helps understand the airport’s carbon footprint and identify areas where emissions reductions can be made. The verification process assures that the emissions calculations are reliable and emissions reductions are real. The airport saves money by being more efficient in building and vehicle energy use. The airport’s emissions reduction projects also bring air quality improvements, which is a boon to the local community and greater Los Angeles region.

    What are your future carbon management plans?

    Van Nuys airport will continue to replace old fleet vehicles and install electric vehicle chargers. Furthermore, the airport will explore on-site renewable energy options at the airport, such as installing rooftop photovoltaic systems on buildings and look to replace old building HVAC (Heating, Ventilation, and Air Conditioning) equipment with more energy efficient units.

    Why did your airport decide to become accredited at Level 1?

    Melbourne Airport wanted to develop an in-depth understanding of our carbon footprint to inform targeted management actions and identify future emissions reduction targets. The level 1 Mapping process means we have a robust, independently verified base year carbon footprint on which to demonstrate emissions reductions over time.

    Further, the mapping exercise means we now have a clear understanding of where our emissions hotspots are. We know that electricity and natural gas consumption accounted for over 99% of our 2016/17 carbon footprint. Using this information means we can target energy savings projects at areas that will make the biggest difference.

    What benefits does accreditation bring to your airport?

    Airport Carbon Accreditation has allowed Melbourne Airport to demonstrate our commitment to better understanding and then reducing the carbon emissions under our control. Accreditation has helped us to focus our efforts on developing a carbon management plan and emissions reduction targets to prepare for achieving level 2 Reduction. Teams across the airport have started working collaboratively to achieve these goals. This will increase the efficiency in which energy reduction projects, and hence greenhouse gas emissions savings are delivered.

    What would you recommend to other airports that are developing their carbon footprint?

    After going through the process ourselves, our recommendations include:

    • Make sure your team has a strong carbon accounting background.
    • Engage with the independent verifier early on in the carbon footprint exercise so as to gain a clear understanding of the auditing requirements, and what information they will need from your team.
    • Identify key emissions hotspots in your carbon footprint for focusing emissions reductions efforts.
    • Be ambitious! Don’t just stop at the carbon footprint, start thinking about emission reduction opportunities and targets from the start of the accreditation process.
    What are your future carbon management plans?

    Melbourne Airport is developing a Carbon Management Plan to identify opportunities across the estate to reduce our carbon emissions. A few key projects currently in train include:

    1. Energy efficiency program: This program aims to reduce 20% of the airport’s base building energy usage by the end of 2020.
    2. Solar adoption program: We will have >10MW of ground mounted solar PV systems installed by 2021.
    3. Tri-gen: Utilising our tri-gen power plant more (using natural gas and a more efficient power plant rather than brown coal grid electricity).

    Why did your airport group decide to become accredited at Level 1?

    ONDA, as an airport management company and as an air navigation services provider, decided to become accredited at level 1 as a first step to become familiar with the Airport Carbon Accreditation requirements from the development of the carbon footprint to carbon neutrality. Once this goal is achieved, we plan will go through all the different processes until carbon neutrality. We chose to become accredited to also comply with the environmental policies of our country that establish as strategic priority environment protection and the use of renewable sources, such as solar.

    What challenges or special conditions did you face while going through the accreditation process as an airport group?

    During the process of accreditation, it became evident that data collection requires the involvement of all responsible parties. Furthermore, the methods used to calculate emissions may be different depending on the source of emissions, types of fuel, and other parameters.

    What benefits does accreditation bring to your airport group?

    ONDA is committed to voluntarily manage its CO2 emissions as part of the global efforts for greenhouse gas management. Thus, we have set up an environmental management system (EMS) to reduce and control the impact of our activities on the environment. Accreditation is consistent with our strategy and brings several benefits to our airports, such as carbon emissions management, environmental assessment for air traffic management operational changes, promotion of best practices, and awareness and efficiency improvements. Furthermore, as accreditation is consistent with ISO 14064 and ISO 50001, it will improve standardization and specialization.

    What would you recommend to other airports that are developing their carbon footprint?

    In order to facilitate calculating the carbon footprint, we recommend:

    • An effective data recording system (e.g., based on ISO 14001).
    • Recording of emissions calculation methods by specific source.
    • Utilisation of technological means for automatic data calculation.
    What are your future carbon management plans for the airport group?

    ONDA intends to expand accreditation to other airports, such as Rabat, Fez and Agadir, and eventually reach higher accreditation levels.

    Why did your airport decide to become accredited at Level 2-Reduction?

    We have always planned our airport activities while trying to reduce our energy consumption. Our nearly $ 300-million construction work, including the rebuilding of the runways and the construction of a new terminal, was a great opportunity to modernize our energy equipment and make a survey to follow and reduce our energy consumption. Joining Airport Carbon Accreditation provides credible recognition of YQB's day-to-day efforts and encourages our employees to operate responsibly.

    Describe up to 4 key projects you implemented to reduce your emissions?
    • Heat recovery from the screw chiller to supply the hot water loop. This measure considerably reduces the amount of natural gas used for heating since heat released by the condensers of the screw chillers is injected into the hot water system when there is a cooling request together with a heating request (decrease 586 tCO2e).
    • Heat recovery on stale air by heat wheels. This measure makes it possible to capture the heat of the exhaust air and transmit it to the fresh air entering the terminal. Not only do the heat wheels recover the sensible heat, but they also recover latent heat, the humidity in the air, which saves heating and humidification. This measure causes a surplus of electrical energy of 649 GJ, but nevertheless allows a saving of gas 4,589 GJ for a net saving of 3,940 GJ (decrease 228 Teq CO2).
    • Geothermal. It is important to point out that geothermal energy, including the heat recovery of screw coolers, allows to substitute about 85% of the required heating energy and 78% of the cooling energy. Greenhouse gas savings are around 356 Teq CO2e per year.
    What benefits does accreditation bring to your airport?

    Improvement of our energy and environmental performance (and the reduction in associated operational costs), a strong commitment from various stakeholders for better performance, better recognition by the public, and motivation for additional efforts to reduce emissions.

    What are your future carbon management plans?

    Among other things, we will continue to take energy reduction measures, such as the purchase of seven aircraft preconditioned air units in 2019, the electrification of part of the fleet of light vehicles and the training of personnel on good driving practices. The goal is to reach level 3 in 2020 and level 3+ in 2022.

    Why did your airport decide to become carbon neutral?

    As part of the continuous aim for excellence across various aspects of operations, Queen Alia International airport worked on achieving carbon neutrality to get a step closer towards realizing the vision of being one of the top 20 airports worldwide.

    Further building on the momentum that started in 2012, the airport wished to reinstate its commitment towards the environment, taking the extra mile towards becoming a greener airport to reflect and promote an environmental-friendly culture at the national and international levels with the support of stakeholders.

    Describe up to 4 key projects you implemented to achieve carbon neutrality.

    Queen Alia International airport has been accredited since 2012. At the same time it has been planning, financing and implementing several midterm power-saving projects. These projects contributed to the reduction of carbon emissions by 7.4% between 2014 and 2017.

    First off, the runway LED lighting project was implemented over the course of two years by the airport’s maintenance team, which replaced normal halogen lights with LED lights, reducing emissions by an estimated 495 tons of CO2 (tCO2) per year. Similarly landside streetlights were replaced with LEDs, bringing carbon emissions down by approximately 41 tCO2 per year.

    Moreover, an overall power saving strategy was implemented by installing motion detection sensors in buildings and by reducing the baggage handling system run-on time, which helped to reduce CO2 emission by around 60 tCO2 annually. Finally, controlling temperature set points were placed at the terminal in order to reduce energy consumption.

    What would you recommend to other airports that wish to become carbon neutral?

    It is important to obtain top management commitment towards achieving carbon neutrality. This commitment will ensure the availability of resources and alignment of all the internal layers of the organization towards reaching the goal. Secondly, it is important to provide visibility on midterm plans. Thirdly, getting senior management support for developing and implementing the Carbon Reduction Management Plan. Finally, it is beneficial to promote a green operational culture among all stakeholders in order to demonstrate the added value regarding cost savings while recognising their roles and contributions.

    What are your future carbon management plans?

    Future plans include maintaining carbon neutrality by further reducing our carbon footprint. For example, a solar farm is planned to operate in 2019, contributing an estimated 23 million/kW, equivalent to 30% of airport consumption. In addition, we are planning to replace normal lights with LEDs on the aprons for 2020.

    Why did your airport decide to become accredited at Level 1?

    AERIS is committed to the sustainable development of San José airport (SJO), in accordance with the environmental policies of Costa Rica. Given that the country has made a public commitment to seek carbon neutrality by 2021, we decided to support this national strategy, starting with level 1.

    It is also a beneficial strategy to set the example for other airport operators so they can go forward with this or similar certifications, starting with their carbon footprint inventory. We also wanted to be in the first 10 airports to be accredited in the region.

    What benefits does accreditation bring to your airport?

    Accreditation allows us to be recognized in the region, by reiterating our commitment to the construction and operation of airports in a sustainable manner and in accordance with the country's environmental objective for carbon neutrality. Furthermore, accreditation is consistent with the vision of our company, as it seeks to be established as a leading airport in Latin America, based on the administration of a secure and financially strong airport, which creates value and is environmentally responsible.

    What would you recommend to other airports that are developing their carbon footprint?

    Developing the carbon footprint is important to contribute to the efforts to reduce greenhouse gas emissions and improve the capacity of companies to face the effects of climate change in key sectors. A key recommendation is to establish a system that organizes all the data. In addition, it is important to involve all the stakeholders in the relevant processes, which is achievable only if the whole organization practices this principle on a daily basis. For example, the accreditation of the airport led to a change of the environmental policy of AERIS to reflect this commitment.

    What are your future carbon management plans?

    In terms of carbon management plans we have already started to implement energy saving measures, such as improved lighting systems and air conditioning. These efforts are now also evident in the new domestic terminal, which is already LEED certified.

    Why did your airport decide to become accredited at Level 1?

    SSR International Airport is the only gateway for air access to Mauritius, a small island state in the Indian Ocean. As many countries in its category, Mauritius is highly vulnerable to the effects of climate change. The rising sea level and climate distortions are only a few of the impacts we are already experiencing. The airport as a key socioeconomic player has the responsibility of ensuring that it contributes to the national development in a sustainable manner. Airports of Mauritius Co. Ltd (AML), together with Airport Terminal Operations Ltd (ATOL), embarked on this programme in 2017 in view of implementing the best practices in terms of carbon and energy management.

    What benefits does accreditation bring to your airport?

    Primarily, Airport Carbon Accreditation is a useful tool, which allows for the measurement and benchmarking of our present carbon emissions and consequently the development of more energy efficient projects. We are confident that investments related to the programme will be beneficial to SSR International Airport in the long term, as the carbon reduction in the airport’s carbon footprint will allow AML and ATOL to make substantial savings in energy and fuel consumption, while contributing to the global effort for environment preservation.

    Also, accreditation has enhanced our airport profile. Since July 2017, SSR International Airport is the 10th International Airport in Africa to become accredited. Through public recognition, we are looking towards securing the firm commitment and engagement of our stakeholders in this important process. We believe that collective awareness and decision are the best means of making a difference and achieving meaningful results.

    What would you recommend to other airports that are developing their carbon footprint?

    Although the tasks involved in collecting the required data may seem tedious, the end result is surely worth the efforts. In this respect airports willing to embark on the programme should consider the following:

    • Obtain high level commitment and engage the staff.
    • Start early and be determined to achieve the set targets.
    • Keep detailed records of fuel and energy consumption through bills, invoices and receipts.
    • Clearly define boundaries and scopes of the carbon footprint.
    • Follow the programme guidance document and use the ACERT tool, which is accessible on the ACI website, to quantify the carbon footprint.
    What are your future carbon management plans?

    We aim at conducting an energy audit of our airport facilities to identify the scope of energy efficiency improvement required and then reduce our carbon footprint mostly through implementation of low carbon technologies. Apart from having already initiated the process for attaining level 2 Reduction shortly, we are keeping in sight our long term objective of achieving carbon neutrality within the next 10 years.

    Why did your airport decide to become accredited at Level 3 Optimisation?

    We believe that climate protection in aviation is a task that the whole industry needs to work on together. As climate protection has been on our agenda for many years, we were able to directly reach level 3 (Optimisation) last year.

    Describe up to 4 key projects you implemented to reduce your emissions?

    As part of our target for carbon-neutral operations, we are improving the energy efficiency of our facilities, pursuing systematic energy management and investing in zero-emission mobility.

    In 2018 we will run the passenger and baggage transport on the ramp at the airport entirely with nearly silent and emission-free ground support equipment. This is part of our scale-up! project in which we significantly expand our electric fleet. Besides electric passenger buses and baggage tugs, our charging stations are also used by battery-powered vans, cargo tugs, conveyor belts and a highloader.

    All other vehicles are refueled with synthetic diesel. Compared to fossil diesel, the synthetic fuel emits significantly less air pollutants. In addition, we offset the CO2 emissions it produces. Furthermore, we have established charging infrastructure of 48 parking spaces, including seven innovative fast-chargers, for passengers and taxi drivers with electric cars. We offer 100% green electricity for their car batteries.

    How did you engage your external and internal stakeholders (e.g., management, employees, passengers, companies operating at the airport)?

    At Stuttgart Airport we are committed to cut emissions wherever we can. This is anchored in our fairport code, which defines values and norms for all employees, and serves as a basis for our corporate fairport Stuttgart Airport strategy.

    Our efforts for climate protection also involve third parties. We cooperate with close partners like airlines, the German Air Traffic Control Authority (DFS) and ground handling companies in order to optimize taxi times of airplanes or to increase the number of electric powered equipment on the ramp. Stuttgart Airport also supports and funds new technologies that will reduce the emissions produced by planes in the future. HY4, a zero-emission and nearly silent four-seater airplane powered by a fuel cell and batteries, had its worldwide first flight in Stuttgart. It proved that the vision of emission-free flying can become true. Until that becomes a reality, passengers receive information on CO2 offsetting programs in our terminals. Emissions of their flight can be calculated and offset at a special computer.

    What are your future carbon management plans?

    Stuttgart Airport is accelerating towards climate protection with two reduction targets:

    1. Reduce by 50% our greenhouse gas emissions by 2030 as compared to 1990.
    2. Run the operations at Stuttgart Airport entirely carbon-neutral by 2050.

    Why did your airport decide to become carbon neutral?

    Since commencing operations in 2001, TAG Farnborough Airport (TFA) has aspired to become a world-class facility. As a business aviation center, TFA acknowledges that comprehensive management of noise, waste and carbon footprint is essential to developing sustainably. Independent certification is paramount for demonstrating a robust and credible approach to carbon neutrality and our work on Airport Carbon Accreditation, which commenced in 2008, provided a structured way of benchmarking against other airports.

    Describe up to 4 key projects you implemented to achieve carbon neutrality?

    Upgrade to LED has been an essential part of our work, to date this has encompassed the terminal, apron high-masts, fuel-farm, administrative center, maintenance sheds and control tower. At the tower alone, upgrading saved 15% (13,902 kwh) of total electricity consumption in the first two months

    With over a thousand people on site daily, our training and procedural approach is important for driving site efficiency. Establishing policy, staff accountability and targeted awareness training, driven by our ISO 14001 certification, has fostered an energy efficiency ethos across site.

    This year TFA committed to REGO energy supply (Renewable Energy Guarantees of Origin), which will see our annual footprint reduced by a further 2,000 tons.

    Sustainable travel has helped minimise liquid fuel use and our network of 20 electric vehicle (EV) chargers enables use of EV’s from small ground handling trucks to a Tesla Model S. We even have a bicycle fleet for footprint free travel between buildings.

    What would you recommend to other airports that wish to become carbon neutral?

    At TFA, our initial move towards Airport Carbon Accreditation was to secure accurate fuel and energy consumption accounting. Smart metering of utilities and robust monitoring were essential in creating the baseline. The combination of carbon neutrality work with an Environmental Management System (EMS) is strongly recommended. This helps engrain sustainable development throughout the organisation and can support carbon reduction by securing buy-in from top management that will percolate to line management and operational teams.

    What are your future carbon management plans?

    Carbon Neutrality is an important milestone in our carbon reduction work but is by no means the end. We are currently working on a total re-fit of our airfield ground lighting system, replacing old tungsten fittings with LEDs. This will see our need to offset substantially reduced over the coming years.
