00:00I think Europe is at the forefront, but are we actually meeting planetary needs of our future generations?

00:07No, we need to speed up.

00:14Hello, you're watching The Big Question, a series from Euronews where we speak to leaders in business

00:21about some of the most pressing issues on today's agenda.

00:24I'm Angela Barnes, and today I'm joined by Marta Sjogren, the co-founder and co-CEO of Pebble,

00:32a Nordic-Dutch company storing CO2 in construction materials.

00:37First of all, can you just give us a little bit more context about what Pebble does?

00:41We take CO2, the gas, the carbon dioxide, and quite simply turn it into CO3.

00:48So it's a solid state carbonate, and thereby we lock away CO2 permanently.

00:54So we mimic a natural process whereby in nature, every day since the beginning of times and forever,

01:03CO2 that's in the air doesn't actually want to be in the air, and it will get pulled down by rain, by water,

01:09and it will merge with magnesium silicates or calcium silicates, and it will form a carbonate rock.

01:18All we do is that we industrially speed that up about 10 million times,

01:23and therefore in an industrial reactor you can just generate the same reaction in minutes.

01:29What other materials can be made with Pebble's technology?

01:32What we have experimented with are bioplastics, regular plastics, paper, and then, of course, concrete.

01:43And as a company, because we want to restore the planetary carbon balance by quite a large amount by the year 2050,

01:49we focus on the most high-priority sector, which is concrete.

01:55And concrete is the most widely used material after water.

02:05Concrete, as well, is often seen as one of the hardest sectors to decarbonise.

02:11Concrete is difficult to decarbonise because cement is difficult to decarbonise.

02:19Cement also, for various reasons, hasn't been really innovated on for quite a long time.

02:26There's really been no incentives.

02:28Now there are incentives.

02:29There is the climate urgency, that's one thing.

02:33There's also the increasing costs of production of everything

02:37because of the supply chains that are getting more complicated.

02:41And finally, and not the least, we need to build more.

02:45So it's becoming more of an agenda item.

02:48Industrial resilience is as a whole.

02:50I read on your website, Pebble's solution reduces the carbon footprint of concrete by 70%.

02:56What does that mean for the construction industry, for example,

03:00which accounts for 8% of global emissions?

03:04Well, firstly, technically, we can reduce it up to that amount.

03:07Now it's up to the value chain to figure out how much of a material it allows to input into the concrete mix.

03:16So what's happening in Europe right now is that the European trading system of CO2 emissions,

03:23so the ETS, is opening up to cement being charged for the emissions that it produces.

03:30Because we replace some portion of cement, therefore those using our material can decrease the cost of material procurement

03:39because we simply do not have a carbon tax because we are a negative emissions technology.

03:45Whilst we're very, very small, like we are right now, of course our cost of production is higher than regular concrete ingredients.

03:53However, within the coming five years or less, we foresee that we will be quite price competitive.

03:58And that's because we're using CO2, which is usually a waste stream, and as an input in the mix.

04:05What could this mean for the future of housing in Europe?

04:08In Europe, if we are good at adopting technologies like ours, we will not only be environmentally more friendly,

04:15but because we're more economical in terms of the overall energy footprint, it should also get cheaper.

04:22And Martha, the EU is often seen as a leader in sustainability.

04:25Do you think the pace of change here is fast enough in Europe, or are we still lagging, would you say,

04:30when it comes to large-scale industrial decarbonisation?

04:34I think that lagging is a question of lagging behind whom?

04:38I think US, China?

04:41No, I think Europe is at the forefront, but are we actually meeting planetary needs of our future generations?

04:50No, we need to speed up.

04:51I can't comment about other parts of the world, other than I think China is doing some interesting things.

04:59I think Europe is ahead, and US is very quickly falling behind.

05:04It's very unfortunate to see.

05:05You touched on the US seems to be rolling back on its carbon capture programmes.

05:10How do you see this divergence shaping the future of global decarbonisation efforts?

05:16It's very difficult to tell what is going to happen.

05:20I mean, every day we wake up to some kind of news that we don't know what to do with.

05:25What we do know is that, you know, talent is central to any economy.

05:30And more than ever before, we have talent from amazing backgrounds in the US reaching out to us

05:37because they're worried about, whether it's about scientific integrity or economically rational decisions,

05:46they're worried about rational decision-making in the US.

05:50And here in Europe, we seem to be quite stable.

05:53And so I think there's going to be a huge influx of talent that just wants to deliver on their career targets

06:00and their planetary ambitions, frankly.

06:02So, Marta, with the EU Clean Industrial Deal targeting a 90% emissions reduction by 2040,

06:09how do you see the role of private companies, like Pebble, of course, in helping meet these very ambitious targets?

06:15I believe that private companies will be at the very centre of this,

06:19leading the way in terms of creating a blueprint for how you can use the built environment

06:25as a sustainability solution and also save money.

06:28But let's not forget, most concrete today is used by public spaces.

06:35So hopefully the public projects that are going to be built in the coming decade,

06:40or slightly more than a decade, will learn quickly from the private sector

06:45and also therefore enable the larger scale-up of these technologies.

06:49How does Pebble's technology contribute to the overall European vision of transforming

06:54the built environment into a massive carbon sink?

06:57So that's a great question.

06:59So in Europe, we are very committed to resource efficiency.

07:04And the built environment, because it is such a huge source of emissions today,

07:09if you can flip that equation and if every single building can be storing a little bit of carbon

07:15as a carbon custodian, I think that goes a long way, both economically and environmentally.

07:20And if you think about the bigger picture, here in Europe, we're quite built out.

07:26But the Global South is just in that process of building out infrastructure and building out cities.

07:32And so from Europe, we can be leading the way with adopting the technologies quickly

07:36and then also partnering with the Global South to actually scale these technologies beyond Europe.

07:42Brilliant. Well, Marta, I wish you the very best of luck with scaling up.

07:45And thank you very much for joining us on The Big Question.

07:48Thank you for having me.

07:51Thank you.

07:52Thank you.
