Jet2 plc has launched its Sustainability Strategy with the vision to become “one of the leading brands in sustainable air travel and package holidays”. Having signed both the UK aviation Net Zero 2050 pledge in 2020 and European aviation industry equivalent earlier this year, we will be implementing our own more ambitious targets to ensure our customers can enjoy Real Package Holidays from Jet2holidays® or scheduled holiday flights with that are more environmentally sustainable.

Many livelihoods around the world depend on travel and tourism with the sector responsible for 1 in 10 jobs globally prior to the pandemic. Additionally, travel and tourism also create tremendous social value by increasing people’s understanding of diversity and promoting inclusion. Like all other sectors, travel has an environmental footprint, with latest estimates putting aviation CO2 emissions at 2.4% of total global emissions. Information from Our World in Data shows that sectors such as Agriculture (18%), Road transport (12%) and Iron & steel production (7%) amongst others also contribute significantly to global CO2 emissions and aviation is therefore a small piece of the much bigger global decarbonisation jigsaw puzzle. Aviation also produces non-CO2 emissions, through its release of particulates, water vapour and NOx, which have a climate warming effect, though there is still a great deal of uncertainty in estimating the size of this impact. As a result, our primary focus is on reducing CO2 emissions which in many cases will also address these non-CO2 impacts.

Although both travel and tourism contribute to climate change, they are, and will increasingly be, adversely impacted by it. The Intergovernmental Panel on Climate Change (IPCC) special report on the impacts of 1.5 degrees of global warming, specifically noted the increased risk to coastal tourism in subtropical regions with impacts including heat extremes, storms and loss of beaches. Consequently, airlines too will increasingly suffer from delays and diversions due to extreme weather events, which means that tackling climate change is also a top priority for our business. Further details about Jet2’s approach to Environmental, Social and Governance (ESG) issues will be contained in our published Sustainability Strategy.


The Group takes its environmental obligations seriously with CO2 emissions from fuel having the biggest impact. As such, Jet2 endeavours to operate in the most efficient and environmentally responsible way possible, minimising both emissions and carbon intensity (emissions per unit of product delivered). In addition, efficient operation also helps to minimise our environmental impact on noise and air quality pollutants.

Jet2 monitors its energy consumption & greenhouse gas emissions (GHG) and uses grams of CO2 (gCO2) per passenger kilometre as a measure of its environmental intensity in line with Streamline Energy and Carbon Reporting (SECR) requirements. The previously used tonnes of CO2e emissions per £ million of revenue and kWh per £ revenue are reported this year for comparison with last year only and, following the disposal of our Distribution & Logistics business, will not be reported in future years.


In the year ended 31 March 2021, total carbon equivalent emissions (t CO2e) from the business were 315,378 tonnes (2020: 2,276,339 tonnes) with over 99% of these emissions arising from our aircraft operations. The remaining emissions sources were ground handling activities, along with our business travel, offices, aircraft hangars and engineering facilities. This equated to 796.61 t CO2e per £ million revenue and 3.22 kWh/£ (2020: 635.02 t CO2e per £ million revenue and 2.56 kWh/£).

All SECR emissions figures, efficiency and intensity metrics are reported in the “Summary GHG Emissions Results” below along with a direct comparison to the figures from the previous financial year. The reductions in emissions across scope 1 and 2 are attributable to the reduced activity of the business over the last financial year due to Covid-19. The scope 3 increase is due to the inclusion of our business travel activities in the current year. The reason for the difference in the variance of the intensity ratios is due to the differing scope of emissions they cover and changes to emissions conversion factors.

* The Group has now disposed of its Distribution & Logistics segment; as a result, the figures shown for the year ended 31 March 2020 have been restated to include only activities from and Jet2holidays.

** Metric uses EU ETS emissions factors and includes aircraft fuel burn only (please see methodology)

*** Emissions included in this are explained in methodology section.

GHG emissions are categorised into three Scopes as defined below:

  • Scope 1 - Direct emissions resulting from the primary combustion of fuels in organisation-controlled premises, vehicles and plant.
  • Scope 2 - Indirect emissions resulting from the consumption of purchased electricity that has been generated off-site and supplied by the national grid.
  • Scope 3 - Indirect emissions associated with the consequences of the activities of the organisation but controlled by an entity outside of the Group.

Prior to the pandemic,’s CO2 emissions per passenger kilometre of 67.0g put us amongst the most efficient airlines in the world, enabled by our “efficient flying” programme. This was illustrated by’s ranking as 11th in the list of the world’s most fuel-efficient airlines in the most recently published 2018 Atmosfair index.

However, this year has proven to be a year of unprecedented operational and financial challenges for the Group, with the flying programme substantially reduced resulting in the airline having its fleet grounded for prolonged periods and also having to refocus the flying programme at short notice to address changes in travel restrictions. Consequently, these factors have had a negative impact on efficiency and our gCO2 per passenger kilometre increased to 89.8g. Additionally, Jet2’s total GHG emissions reduced over 86% compared to the last financial year.

In the period from 2011 to 2020 improved efficiency by more than 19%, averaging 2.4% a year; substantially ahead of ICAO’s global annual average fuel efficiency goal of 2% until 2020. The chart below shows our historical progression, increasing our efficiency year on year followed by the impact of Covid-19 in the current year compared to our expected efficiency.


The impact of Covid-19, which is outside of our control, goes against both our long-term trends and also’s efficiency aspirations. However, our efforts, to increase efficiency across our operation since 2010/11 up until the start of the pandemic have saved in excess of 1.8 million tonnes of CO2.’s “efficient flying” programme has contributed significantly to these improvements. This programme focuses on all aspects of the airline’s operation which can influence or directly impact the efficiency of its flying activities including: single engine taxi operations; pre-conditioned air; careful fuel requirement planning; performance-based navigation approaches; reduced thrust take offs and continuous descents; and using electric ramp vehicles and fixed electrical ground power where available. These actions, combined with ongoing weight saving initiatives from lightweight seats, lighter catering carts, the removal of paper manuals and the introduction of carbon brakes have saved over 2,600 t CO2 this financial year, the equivalent of planting 130,000 trees.

In addition,’s investment in 34 new more fuel-efficient Boeing 737-800NG aircraft which were delivered between 2016 and 2019 saved over 12,500 t CO2 this financial year in a like-for-like comparison against our existing fleet. Furthermore, 95% of the total fleet is fitted with fuel-saving winglets, which saved an additional 11,800 t CO2. Combined, these measures have saved over 24,000 t CO2, equivalent to taking approximately 13,200 cars off the road in the UK.

However, it is not only the environmental impact of our aircraft fleet that we seek to reduce. are also committed to working collaboratively with our partner airports and air navigation service providers to minimise environmental impacts on local communities. As a result,’s ground handling operations, which deliver services to nearly 50% of our flights, have had significant investment in new equipment over recent years, with 42% of our ground service equipment (GSE) now electric or hybrid. Additionally, within our non-electric fleet, over 70% of our aircraft tractors meet the Euro 5 / 6 standard and all ramp cars and minibuses meet the Euro 6 standard, meaning our ground vehicles produce fewer NOx and particulate emissions. We are also installing telemetry (C-Track) on board our ground service equipment to monitor fuel use, ensuring not only that the equipment is efficient, but our processes and training are optimised for efficiency. These actions minimise not only CO2 emissions from ground sources, but also noise and pollutants that give rise to air quality issues, thereby minimising the environmental impact on the local communities which we serve.

In addition to carbon emissions, we have focused on other environmental impacts within our operations, with’s Inflight Retail team making good progress in reducing single use plastics, replacing with sustainable alternatives such as wooden cutlery and cardboard meal boxes. Where non-plastic alternatives are unavailable at present, we are turning to products made from a higher proportion of recycled plastics such as rPET water bottles. As part of our commitment to the circular economy, we began our in-flight recycling programme in November 2019. In-flight recycling means material which previously would have gone to landfill, such as rPET plastic products, comes back into the material supply chain, closing the loop by ensuring these materials are able to be used again. We estimate this programme will help to recycle up to 50% of on-board waste which would mean recycling up to 1.2 million knives, forks and spoons, 2.9 million wooden stirrers and 4.7 million plastic products, based on usage in the year ended 31 March 2020.

Additionally, at our new operating base in Bristol, we have ensured that only efficient LED lighting is installed which has been optimised with localised light sensitive adjustment and occupancy sensors to automatically turn off or reduce lighting levels as necessary. Finally, we have moved to a proportion of our head office electricity (20%) being from renewable sources and plan to increase this further in the coming year.


This assessment has been verified by a third-party (Delta-Simons Environmental Consultants Limited) carried out in general accordance to ISO14064-1:2006 Greenhouse Gases – Part 1: Specification with guidance at the organization level for quantification and reporting of greenhouse gas emissions and removals and is produced in line with UK Government Environmental Reporting Guidelines: Including Streamlined Energy and Carbon Reporting Guidance (March 2019) in conjunction with UK Government GHG Conversion Factors for Company Reporting.

Carbon conversion factors have been taken from ‘DBEIS/DEFRA – UK Government Conversion Factors for Company Reporting 2020’ as most of the reporting period falls within the 2020 calendar year. This is in line with environmental reporting guidance.

GHG emissions have been assessed using the ‘financial control’ approach, meaning that the Group reports on emissions resulting from its operations, within its direct or indirect financial control. The assessment includes the following aspects:

  • Scope 1: Aviation Fuel, Building Fuel and Ground Fleet.
  • Scope 2: Electricity purchased (location-based).
  • Scope 3: Employee Mileage, Employee Fuel (including Avgas) and Transmission and Distribution.

Actual data was unavailable for business rail and flights and reliable estimates could not be produced. The reporting and assurance process have concluded that these areas are not of significance to our overall carbon footprint data. ‘Well to tank’ emissions from jet fuel will be included in future reports.

Grams of CO2 per passenger kilometre is a standard aviation industry fuel efficiency metric and is calculated by dividing total CO2 production by total passenger kilometre. This metric includes all the fuel the airline uses including engine testing and training flights. The passenger kilometres and CO2 emissions are calculated using EU ETS methodologies and emissions factors. also reports grams of CO2e per passenger kilometre which includes all scope 1 & 2 emissions and also scope 3 emissions from business travel in rental cars and employee-owned vehicles where the company is responsible for purchasing the fuel, as required by SECR. This metric uses carbon emission conversion factors from ‘DBEIS/DEFRA – UK Government Conversion Factors for Company Reporting 2020’.


We are committed to net zero carbon emissions by 2050 but aspire to bring this date forward. Our decarbonisation flight path covers all of our business operations, on the ground, in the air and in resort so we can address sustainability at every stage of the journey. Across each we have measurable KPIs and commitments.

The key objectives of the flight path are to:

  • Make sure our business strategy has the environment and sustainability at its heart.
  • Work collaboratively with the wider industry and suppliers to develop aviation that is sustainable.
  • Communicate our sustainability publicly and hold ourselves to account.

We are committing to reporting annually on the progress we are making against the targets in the strategy to ensure that we are transparent in the actions we are taking to champion sustainability within our business and throughout our supply chain.


Our operations on the ground will be carbon neutral from 2022 and over 50% of our ground service equipment (GSE), will be powered by electricity, either fully electric or hybrid, or by biodiesel by 2023. We will continue to expand our Jet2 electrification programme so that as much equipment as possible contributes to reducing our ground-based emissions.


At Jet2, we’ve got your carbon covered. On 1st January 2022, we will launch one of the world’s largest airline carbon offset schemes, offsetting all emissions not already covered by our contribution to existing schemes (CORSIA and UK and EU Emissions Trading Schemes). This programme has been developed with independent experts, and certified to the highest standards, with real-world carbon reduction impacts in mind. Our offset programme contributes to growth of renewable energy around the world, by providing funding to accelerate the transition away from fossil fuel generation in circumstances where this would not otherwise happen. However, we know that offsetting is not enough.Whilst we are already one of the world’s most efficient airlines, we will continue to invest in the latest technology and innovation, as demonstrated by our new order for up to 75 Airbus A321 NEO aircraft. The Airbus A321 NEO which has more seats, delivers a 20 per cent reduction in fuel consumption and CO2 emissions per seat against previous generation single aisle aircraft models. It is therefore, in our view, the most fuel-efficient and most sustainable aircraft in its class. This will make flying with even more efficient and further reduce emissions per passenger. We are committed to using all currently available options to reduce carbon. In the short to medium term, developing and utilising fuel with lower carbon output is one of the best ways to deliver on this. That is why is working with a leading supplier of Sustainable Aviation Fuel (SAF) – which reduces carbon emissions by around 80% compared to fossil jet fuel. We believe SAF is the medium-term solution for the sector and our SAF partners will use a number of techniques, including converting waste into fuel for our planes, which will decrease the waste going to landfill and create local jobs. Our commitment to sustainability goes beyond carbon. We are committed to the circular economy and will cut 80% of single use plastics by 2023 compared to 2019 levels – equivalent to removing 11m items. This relates to items purchases directly - cups, cutlery, stirrers, drink lids and plastic bags. We are also taking steps to increase and report on recycling levels.


Hotels play an important part in protecting the local environment. Ensuring sustainability and working with our partner hotels to promote sustainable operations will help tackle climate change and other localised issues such as waste and water stress. We plan to put in place a hotel sustainability labelling scheme and empower our customers to filter their hotel selection by sustainability. By 2023 Jet2holidays will develop its own Hotel Sustainability Charter covering hotel management as well as environmental, social and economic business impacts.
