The United Nation’s World Environment Day has been promoting awareness of the environment since 1947. The day is focused on encouraging the global population to do something to help protect the environment. This year, over 143 countries are expected to participate in the day that has the theme ‘connecting people to nature’.
As a major manufacturer, our operations have an impact on the environment – from the energy and resources we use to the waste we generate and we are committed to minimising the impact of our worldwide operations. Each of our businesses sets clear targets to use resources efficiently with a focus on reducing energy and water consumption, and waste generated.
Our technological focus and commitment to innovation allows us to develop solutions to lessen the environmental impact of our operations. We are also helping our customers do the same. From designing submarines with better waste compacting systems to helping customers make vehicles last longer, our engineers work to reduce environmental impacts across the product lifecycle. The Group’s total greenhouse gas emissions decreased by 4% in the 12 months to 31 October 2016.
Below are a number of examples from across our business highlighting the work we are doing to increase the sustainability of our operations and to support our customers in the same goal.

Increasing energy efficiency at Warton

Our Warton site in Lancashire, UK run by Military Air and Information (MAI), is the hub for production and assembly on the Typhoon and Hawk Advanced Jet Trainer. The critical testing and production work carried out relies on computing infrastructure that uses significant amounts of energy, for example, in air conditioning (AC) systems.
Working with our partner Airedale Applied Thermal Innovation, we set out to enhance cooling performance with a much higher level of energy efficiency, while keeping the computer systems fully operational. Joule Consultants helped us to see how we could reduce the energy consumption of the AC units in the computer room by up to 80%.
Airedale’s control division devised a bespoke approach, linked to the existing building management system, involving new fans, chilled water valves and controls on more than 70 AC units. This resulted in an estimated 70–80% reduction in energy consumption, reduced carbon emissions and an approximate saving of £350,000 per year. We expect to recoup the full costs of the project within 15 months.

Deployed Energy Management System (DEMS)

Providing electrical power in off grid locations can be an energy intensive activity, with varying patterns of energy usage meaning that extra demands are placed on generators.
We designed and developed a Deployed Energy Management System (DEMS), an innovative plug-and-go solution that distributes power in a more efficient way in operating bases not connected to electricity grids. It works by controlling generators, maintaining storage and intelligently managing demand to meet operational requirements and energy use patterns.
The generators charge a battery system controlled by the DEMS console which switches the generator off when the batteries are fully charged. Power on demand can be drawn from the batteries, resulting in increased efficiency as well as fuel and maintenance savings.
In conjunction with the generators, the system can also use alternative energy, such as solar power and wind energy, making it a more sustainable option.
The success of using DEMS has been proven during a series of trials at MOD bases in the UK, Cyprus, Kenya and Mali.

HybriDrive® Solutions

HybriDrive Solutions, produced by our Electronic System’s division, are our advanced electric drive systems providing environmentally-friendly propulsion solutions for transit, military, marine and rail vehicles.
Each year our HybriDrive systems transport one billion passengers, saving 15 million gallons of fuel while eliminating 160,000 tons of COfrom entering the atmosphere. In the first half of the year, we delivered more than 1,000 hybrid-electric propulsion systems to transit agencies around the world and in April we achieved the milestone of having approximately 6,000 HybriDrive® systems in service.
Cities around the world continue to pursue zero-emission transportation solutions and to look for practical ways to incorporate electric technology into their bus fleets. Cities including London, Paris, Boston and Seattle are now using BAE Systems’ HybriDrive technology to save fuel, reduce noise and improve local air quality.

Energy efficiency at Portsmouth Naval Base

In 2015,  UK and Maritime Services completed a large scale installation of solar panels at the Portsmouth Naval Base to increase energy efficiency and financial savings.
Installing the new 500 kilowatt system is expected to generate energy savings worth more than £1million over the next two decades.
BAE Systems has already implemented a further range of energy and cost-saving measures such as the installation of LED lighting in offices, LED street lighting, air-source heat pumps and intelligent control systems.
The redevelopments support the Ministry of Defence’s drive to create a more modern and energy-efficient Naval Base fit for the 21st century.
The programme in Portsmouth, managed by Energy Solutions and Services, has helped transform the buildings into clean energy-producing facilities. Their improved efficiency has ultimately reduced costs for the Ministry of Defence.

Solar arrays in Sweden

Our Hagglunds business in Sweden was awarded an ‘Environmental Eagle’ award by the municipal government for the establishment of the solar array at its plant in Ornskoldsvik. This is the largest façade-mounted array in Scandinavia, consisting of 1,465 panels on two building façades. Together, they generate an estimated 312 megawatt hours of electricity per year – enough to power 40 houses.

A green upgrade for Land (UK)

Our Land (UK) manufacturing facilities have recently undergone a £206m investment. This work has resulted in improved energy and resource efficiency with key buildings designed to meet the Building Research Establishment Environmental Assessment Method (BREEAM) ‘very good’ standard.
Specific improvements include a new purpose built resource-efficient facility at Washington, the removal of a coal fired boiler house at Radway Green, the installation of new effluent treatment plants at Washington and Radway Green and rationalisation of the steam supply system at Glascoed.
