A sustainable Museum

As advocates for the planet, we try to think sustainably when making decisions and to operate in a way that’s kind to the environment.

We aren’t perfect, but we’re looking at ways we can reduce our carbon emissions and energy consumption, reuse and repurpose technology and encourage everyone to refill and recycle.

Read our environmental policy and take a look at our Sustainable by Nature Plan animation.

Carbon Emissions

Greenhouse gases are doing serious damage, so we want to limit and reduce the amount released into the atmosphere through our operations. The UK Government has asked everyone to reach net zero by 2050, but we’re aiming to get there by 2035.

It’s going to be complicated because we care for one of the most important natural history collections in the world, which needs specific conditions to maintain it and keep it safe. Nevertheless, we’ve set ourselves targets to help drive down our emissions as much as possible.

Our plan is to switch to greener technologies and prioritise energy efficiency and sustainable design.

Some parts of our work will always generate a small amount of carbon dioxide, no matter how energy efficient we become. Once we’ve done everything we can to tackle our emissions, we’ll explore carbon-offsetting schemes to achieve true net zero, but these will be a last resort.  

Energy

We’ll always need energy, so we want to reduce how much we use and source it sustainably.

Solar panels were installed in 2020 at our Tring site, suppling enough energy to power the Ornithology Building. In 2022 we also installed a small solar array at our South Kensington site on the roof of our Palaeontology Building.

At South Kensington, most of our electricity comes from an onsite trigeneration energy centre. Although it burns natural gas, it combines cooling, heating and power to reduce waste and is the most efficient way for us to manage our energy needs at the moment. However, we’re looking into how we can decarbonise this energy centre by 2035. Works so far have included equipment upgrades and the introduction of heat pumps, as well as a range of Energy Conservation Measures that’ll help us gain tighter control and management of the energy consumption across our South Kensington site.

Of the electricity we import from the grid, 20% of it is under a Power Purchase Agreement (PPA) supplied by wind farms. As well as this, the supply at both our Tring and Wandsworth sites are backed by Renewable Energy Guarantees of Origin (REGOs), which certify that the equivalent volume of electricity is generated from renewable sources.

To help achieve our energy saving targets, we’ve recruited an Energy Manager and have committed to reducing energy intensity by 40% by 2030. We’ll do this by making existing systems more efficient and building energy efficiency into all new projects.

Travel

Our staff only travel when it’s necessary because we know that planes and cars produce greenhouse gases.

Sometimes our staff have to travel on planes to transport specimens safely, collaborate with partners effectively or study fragile ecosystems in detail. However, we’re working to reduce our reliance on flights and have introduced a new travel policy that prevents our staff from taking internal flights within the UK (except for reasonable adjustments and exceptions) and business-class flights.

Our vehicle fleet is small but we plan on moving to all electric vehicles by 2027 in line with the Green Government Commitments.

Waste

Carbon emissions aren’t everything. Pollution and overconsumption are two big threats to nature.

Our scientists are at the forefront of research into the harmful effects of plastic and chemical pollution. Even on our doorstep, we know that more than a quarter of fish in the Thames Estuary are eating plastic.

That’s why we’re trying to generate as little waste as possible and working to maximise reuse and recycling.

• Visitors can recycle waste in our cafes and at our exits.
• We have an internal reuse page to extend the life of our furniture and other items.
  
• We provide facilities for mixed recycling as well as cardboard, electrical equipment, scrap metal, glass and food waste.
  
• We work with suppliers to make use of take-back schemes for specialist equipment and packaging.
  
• Set works, seating and walls from our temporary exhibitions are reused or recycled wherever possible.
  
• We transfer mounts and panels to collections spaces following the closure of an exhibition to enhance those areas for research visitors.
  
• We’ve installed more water stations on our sites to encourage our visitors to refill bottles.

Where does our waste go now?

• None of our operational waste goes to landfill.
  
• General waste is incinerated and produces energy.
  
• Mixed recycling is sent to a UK processing facility, sorted into its component parts and then sent on to various reprocessing plants.
  
• Food waste is sent for anaerobic digestion and made into fertiliser. The gas emitted from this process is captured and used for energy.
  
• Cardboard is taken to a card pulping plant and turned into new products.
  
• Glass is taken for recycling.

We’d aimed to increase our average operational recycling rate to at least 60% but despite an overall reduction in the amount of waste we produce, we’ve fallen short of our target, remaining in line with the national average.

We have been producing less waste, with volumes remaining below pre-pandemic levels.

Our next steps

We want to push ourselves to do better. To help us plan how to get there, we’re going to:

• monitor our waste more closely and undertake a series of waste audits
• find new opportunities to facilitate reuse
• raise awareness of recycling best practice

Water

Water is one of Earth’s most precious resources.

The United Nations (UN) estimates that water scarcity affects more than 40% of the global population, a figure that’s projected to rise even further. By 2030 the UN wants every country to begin using water more efficiently, to make sure there’s enough clean water to go round.

We’ve gradually been undertaking measures to reduce our water consumption, such as fitting dual-flush cisterns that reduce the volume of water used to flush toilets and installing sensor-controlled or push-button taps, which can reduce water consumption.

By 2026 we’re aiming to reduce our water consumption by 20% against a 2017/2018 baseline, by:

• monitoring our water consumption more closely
• identifying opportunities to reduce consumption and wastage
• educating staff

Investments and income

Money is powerful, so we want to make our money work for good.

We investigated opportunities to move our investments into a sustainable fund in 2020/2021 and in May 2022 we transferred to a Charities Ethical Investment Fund that’s managed in accordance with the UK Stewardship Code.

All new starters have their pension contributions automatically invested in a new default investment strategy, which invests responsibly and aims to help to contribute to a better future.

Supply chains

Many of our goals rely on cleaning up our supply chains. We want all our suppliers to join us in working in a way that’s kind to nature. We have several procurement policies and supporting documents that embed sustainability into our procurement process.

Carbon emissions come from all sorts of places, including our own buildings and the manufacture of the goods we buy. 

Emissions are split into three scopes. Scopes 1 and 2 cover the emissions resulting from energy use in our buildings. We’re tackling these right away. Scope 3 covers everything else, including the procurement of goods and services, and is estimated to be twice as much as our Scope 1 and 2 carbon emissions.

We have limited control over Scope 3 emissions and their calculation can be complex, making them more difficult to tackle. For that reason, they’re not currently included in our net zero target, although we’re committed to encouraging advocacy for the planet within our supply chain, monitoring the emissions of our purchased goods and services and reducing the impact of our purchases.

Find out about what our retail teams and catering providers are doing too.

Our future plans include:

• obtaining the Scope 1 and 2 emissions of our top suppliers
• introducing sustainable procurement guidance
• building sustainability decisions into our procurement process

New buildings and exhibitions

All our new projects will have sustainability at their heart. 

• All new buildings will be designed and built to be low carbon, energy efficient and fossil fuel free, including everything being built for our Urban Nature Project.
• We’ll think more carefully about how to make new projects sustainable from the beginning. 
• Exhibitions will be designed to support circularity and minimise waste. Focusing on the reuse of materials and showcases, and recyclability at end of life.

Retail

Our ambition is to become a leader in sustainable retail. This means looking at sustainability in the round, so we’re working with our suppliers to look for solutions to challenges such as eliminating excess packaging and single-use plastics, sourcing more sustainable materials and using more sustainable manufacturing processes.  

Here are some of the things we’ve changed in our shops so far: 

• All clothing sold through our retail and licensing programmes is made of 100% recycled, BCI or organic fabrics. We’re also working to replace virgin polyester used in our accessories with more sustainable alternatives.
  
• All soft toys sold in our shops or through licensees are filled with recycled PET. We’re also investigating further ways to make our plush toys even more sustainable, such as using rPET for the outer fabrics and components where available.
• We’ve stopped using bubble wrap and now use a recycled paper alternative onsite and in our online deliveries.
• Our single-use bags are made from 100% recycled paper.

Our retail and warehouse teams are also: 

• Sorting delivery packaging to separate paper, carboard, PET and HDPE plastics for recycling. We work with our suppliers to remove delivery packaging where possible and to minimise any packaging used, for example by packing t-shirts and accessories in a larger outer bag, rather than individually.
  
• Reusing cardboard from deliveries in our ecommerce packaging.
  
• Focusing our ranges on products that are more sustainably sourced, using carefully chosen materials, water/plant-based inks and finishes and ensuring products are good quality and made to last. We’ve also selected products that help our customers to live a more sustainable lifestyle by reducing their reliance on single-use plastics and throwaway items.
  
• Working with retail suppliers to reduce packaging and single-use plastics.
• Making our product packaging as easy as possible for our customers to recycle by choosing widely recyclable materials where possible and providing clear disposal information on new products.

With such a large and varied product range, we recognise that we have a long way to go and we’re working hard to find the most sustainable solutions.

Purchases help us to care for our collection of more than 80 million specimens as well as support our 300 scientists, who are studying the natural world. 

Our progress

We won’t reach our goals unless we keep an eye on how we’re getting on. 

We want to keep setting ourselves new targets and hope our Sustainable by Nature Plan will help us operate in a greener manner than ever before.
