The UK’s greenest businesses – who are they and why are they so sustainable?

With scientists sounding increasing levels of alarm over the state of the global climate, and the public demanding climate action from their leaders, it’s not just governments who need to step up and act. Businesses must also do their part and go green, but how is it best they proceed?

To answer that question, we’ve taken a look at some of the UK’s most innovative and sustainable businesses. Their example is perfect for anyone wanting to know the secrets of green yet profitable business transition.


A mobile app that was created with the mission of reducing waste, Olio lets users see which of their neighbours and local businesses have surplus food they are giving away. Through the app, individuals and companies can connect and share with one another, reducing the issue of food waste and spreading low-cost and free food throughout the community to the people and organisations that need it most.


Communications provider Vodafone has set out to achieve net-zero carbon emissions by just 2027. They’re doing this in a variety of ways; switching to 100% renewable energy, tackling network waste, and offering refurbished phones to wallet-savvy customers.

The company is also controlling air pollution emissions through the use of Internet of Things (IoT) technology, which allowed them and their customers to reduce over 7.1 million tonnes of emissions in 2021 – five times more than the company generates annually, according to their stats.


Brew-tastic Toast produces beer and ale from leftover bread – as opposed to the barley that breweries typically use. This doesn’t just reduce the problem of food waste, it also has a great impact on water use, carbon emissions, and land use, given that they are no longer using the farmland and infrastructure required to grow grain.

What’s more, toast is also entirely non-profit, donating every extra penny to charities aiming to change the world’s food production systems for the better.


One of the UK’s biggest and most well-known insurance companies, Aviva also has a reputation of addressing environmental matters. The company has decided to put sustainability into everything it does, changing its governance, comms, decision-making and much more to achieve net-zero emissions.

This will start with net-zero for internal operations and its supply chain by 2030, with all investments made by the company being net-zero by 2040. Carbon emissions are down by 76% since 2010, driven by investment in on-site green energy and investment into electric and hybrid vehicles.

Making business sustainable is crucial in 2022, and the above examples are just some of the many ways companies are changing. Do you own a business? How do you think companies should tackle the climate emergency? Let us know sharing and spreading the word!
