technology is killing our planet

A bit intense? Sorry about that but we think it’s time we had an honest conversation about our relationship with technology and the impact it’s having on our planet.

the honest reality

the technology industry is responsible for around 3.7% of greenhouse gases – that’s around the same amount as global aviation.

Because we rarely think about the infrastructure powering a device it can be easy to underestimate its impact.

As more money is invested into tech its carbon footprint is only set to grow. This means more energy and more raw materials. By 2040 communication technology will account for 14% of the global environmental footprint (Journal of Cleaner Production, 2018).

But no-one’s talking about it.

We don’t think that’s very honest.

We’re Carbon Negative – it’s a positive thing, we promise

We’re the UK’s only carbon negative mobile network. That means that we remove double the CO2 emissions created by our members’ phones. We capture twice the emissions for every email sent, phone call made and selfie taken- and all the emissions associated with their manufacture and charging. We also do this for everything we do at Honest HQ. So we’re carbon negative across our whole business.

We calculate all those emissions then look to reduce and remove that carbon from the air. If you want to read more about what it means to be a carbon negative company read our blog here.

How do we capture carbon?

We do this primarily by planting trees – working with On A Mission to plant trees all over the world, including Madagascar, Brazil and Colombia. Trees are a great way to capture carbon because they’re not as expensive as some other methods. They also provide lots of social benefits like employment, encourage biodiversity and help prevent soil erosion – but they take a pretty long time to grow and don’t capture carbon permanently.

As a tech company we want to lead the way in how businesses remove carbon from the air. The most common way of doing this is through planting trees, but there’s more to do beyond that. Don’t get us wrong – we love trees! They’re great. But there’s only so much land to plant them – so we need to look at other ways to capture carbon. That’s why we work with Klimate to capture all our Honest HQ and members’ emissions – 95% through trees and the other 5% through Direct Air Capture (DAC) and Biochar.

We’re investing in carbon capture technologies beyond just afforestation. It’s important that we invest in carbon capture technologies with greater permanence, such as Biochar and Direct Air Capture.

going beyond carbon

What is Biochar?

4% of Honest’s emissions are captured using a process called ‘pyrolysis’ to create Biochar. Sorry, we know that’s quite a complicated sentence so let us explain…

Pyrolysis is basically breaking down organic materials using lots of heat. It’s a very technical process in which biomass or green waste (waste products from plants) is exposed to high temperatures in an oxygen-free environment. Biochar – a charcoal-like substance – is produced by this process (which releases only a negligible amount of CO₂ into the air). Besides being a waste product, biomass contains large quantities of carbon so where it would normally decompose and release carbon instead we’re left with a kind of porous charcoal, which is durable and made up of 65-80% carbon – it’s awesome because it locks up carbon permanently.

We work with Carbonfuture to do this – who have a bunch of projects creating Biochar and using it in farming processes across Europe and the US. This can be as direct application to soil, adding it to compost, animal feed, stable bedding or slurry. This technique also produces byproducts – pyrolysis oils or process gases – that can be used to generate energy and heating. But people have also started using it to create paints, building materials, insulation materials, textiles and other high-tech materials. Which is great news because this could replace scarce resources like sand.

Biochar is still pretty costly and the Biochar industry isn’t the only one with an eye on plant waste (biomass) from agriculture or forests. The dawn of new technologies, such as Bio-energy or BECCS, could increase the competition for biomass.

Direct Air Capture Fans from Climeworks
What is Direct Air Capture?

Direct Air Capture (DAC) is the most expensive technology we use to capture carbon from the air. Even though it’s pretty early in its development, companies like Honest Mobile are leading the way in its early adoption. As a tech company we think it’s important to invest in new tech that will help stop the climate emergency. Combined with a safe and permanent storage solution, DAC is an incredible form of CO2 removal.

We work with the Swiss company Climeworks whose DAC technology captures CO2 from the air. The CO2 is then mixed with water and pumped deep underground. Through a process of rapid underground mineralization provided by Climeworks’ partner Carbfix, the captured CO2 is turned into stone and removed from the air safely and permanently for thousands of years. We use Climeworks’ service to remove 1% of our emissions. DAC is well worth the cost because it’s very permanent and it’s easy to trace – and as more people invest in it the cost will go down.

we declare a climate emergency

Honest Mobile is proud to have joined the Business Declares network. A collection of businesses that acknowledge the climate emergency and the need for urgent action to mitigate its effects.

Building a mobile network that puts people and our planet first has been part of Honest’s mission since Andy and Josh started the company.

As a B Corp, we’re legally committed to consider people and the planet in all decisions we make, (we’d do it anyway, but it’s nice for you to know!). We’re carbon negative, removing double the carbon created across our business and by our members’ phones. As a tech for good start up we invest in innovative carbon capture technologies Direct Air Capture and Biochar to do this. We’re also a member of 1% for the Planet, donating 1% of our members bills’ to our tree planting projects with TreeSisters. We’re the most ethical mobile network voted for by The Good Shopping Guide and top rated by Ethical Consumer.

We never claim to be perfect, but as a business we’re always looking for ways to become more sustainable and take action to stop the climate crisis. We’re always glad to find other likeminded businesses to share ideas and take action with.
