In 2016 we published our first Carbon Management Plan, which aimed to build on efforts to reduce our carbon emissions which have seen us achieve a 40% reduction since 2013.
In early 2020, we began work on an updated high-level plan to reduce carbon emissions, but during the pandemic our priorities shifted to focus on immediate and direct carbon and energy reduction measures. Taking advantage of the unprecedented fall in traffic and passenger volumes, we examined our operations and infrastructure in detail, with the aim of eliminating as much carbon from our operations as possible.
And we have been successful, reducing our emissions by approximately 1700 tonnes, or by 18%, in 2020/21, compared to the previous financial year. While we expect emissions to increase in line with passenger volumes as the recovery gets underway, we are determined that many of the measures we introduced in the pandemic will be extended in the long term, creating a more sustainable operation for the future.
We're also fully engaged with the industry's efforts to decarbonise, supporting our partners in IATA, Sustainable Aviation and the Jet Zero Council to decouple the growth in aviation from the growth in emissions. This is being achieved through the development of carbon-efficient airport infrastructure, the introduction of fuel efficient operations, the drive for sustainable aviation fuels and the ultimate delivery of zero-emissions aircraft.
We will publish an updated Carbon Management Plan during 2021. This will focus on the next five years and will set out a high-level roadmap for our journey to become a net-zero carbon airport by 2033, prioritising zero carbon airport operations and minimising carbon offsets.
