PURA Sponsor / TED Tech Host Sherrell Dorsey
Welcome to TED Tech, a podcast from ted. I'm your host Sherrell Dorsey. Today we're continuing our special miniseries about climate solutions and the technology that can lead us into a greener, more equitable future. Across four episodes, we're bringing you conversations from ted's Countdown Climate Summit in Nairobi, Kenya, where some of the world's greatest visionaries shared cutting edge solutions to the ongoing climate crisis. It's the defining challenge of our time. So how will we meet it? Before we dive into today's conversation, let's pause to consider a sobering fact. Even if we halted all emissions today, the carbon already in our atmosphere would continue to warm the planet for decades to come. That's why the world's attention is increasingly turning to carbon removal and why leaders like Dr. Xu Hao are so pivotal in shaping the solutions of tomorrow. Dr. Howe serves as Vice President of Sustainable Social Value at Tencent, one of the world's largest technology firms and the company behind WeChat, with over a billion active users. In this role, he leads Tencent's carbon neutrality lab and directs CarbonX, the company's ambitious platform investing in breakthrough carbon removal and decarbonization technologies, particularly in hard to abate sectors like cement, steel and chemicals. Under his leadership, Tencent isn't just focused on reducing its own operational emissions, it's actively funding and accelerating early stage high risk climate solutions through its lab, accelerator and infrastructure tracks, moving ideas from concept to commercialization. Today, we'll explore with Dr. Howe what it takes to push carbon removal technologies from promising prototypes to real world impact. And because it's important to challenge and contextualize these efforts. We'll also ask why should a company like Tencent, known more for social platforms and gaming than heavy industry, be so invested in carbon removal? What role do tech giants truly have to play in the global climate movement? It's an important conversation at a pivotal time, and I'm thrilled to welcome Dr. Xuhao to help us make sense of what's next. Before we dive in, a quick break to hear from our sponsors.

Sherrell Dorsey, TED Tech Host
CarbonX specifically focuses on hard to abate industries and technologies like what's called Carbon Capture Utilization Storage or ccus. What do you see as the single biggest misconception or challenge that needs to be overcome for some of these carbon removal technologies to really achieve widespread adoption and really like significantly impact global emissions?
- [08:45]
Dr. Xu Hao, Tencent VP of Sustainable Social Value
The single challenge they face is actually they cost too much today, right? So we really need to push the technology forward so that they can reduce their cost and they can scale up, then they can play a big role. So at the moment we see a lot of the technology are actually coming out of the laboratory in the research institute and become startups or actually integrated into many of the existing hard to abate sectors and begin to make a material impact. By material impact I mean, okay, in the lab you're probably working on kilograms or a few tons and then go into the industry, you are working with at least 10 or 10,000, 10 or millions of tons, then it is really helping some of the industry decarbonize. That is important because we have to have the option out there so that the industry know, okay, I can choose this pathway. Otherwise let's say if the technology is not there, you probably have some so called technology locked in. Effect, if you choose a relatively higher carbon technological pathway, you build a plant, that plant will be there for 15, 20, 30 years, then the emission is almost locked in.
- [10:00]
Sherrell Dorsey, TED Tech Host
And I love that you speak to the ecosystem at large, because the more investment, the more time put in the advancement, the lower the costs. But that opportunity still has to be there. And there's the CarbonX initiative which funds projects across the labs. Can you share some examples from maybe one of the winning cohorts from this project that embodies this idea of tech for good and this vision around what this kind of innovative approach or potential can be to really scale.
- [10:32]
Dr. Xu Hao, Tencent VP of Sustainable Social Value
So when we launched the first round of CarbonX what we found very interesting if look at all the winning startup cohort, most of them are actually doing carbon utilization in China. And then we think okay, why is the reason? It's probably because number one, we don't have a carbon price that cover most part of the economy. We have our carbon market, but it's only covering part of the economy. It's expanding to cover most of the economic activities pretty soon, but at the moment that didn't cover that part. And secondly, carbon utilization in terms of so called MRV issues, measurement, reporting and verification is complicated because how do you calculate if I use 1t of carbon dioxide from a chimney, how much carbon abatement I have is technical and is complicated. As a result, these guys have to compete head to head with the fossil fuel alternative, whether it's make plastic or make calcium carbonate or make building materials cement. They have to compete head to head with the fossil fuel alternative without the price on carbon. And then the good thing about it, or exciting, they're actually much more than what we expected startups, they can actually compete with the fossil fuel alternative. They can make cement using steel slug and carbon dioxide at a similar cost or sometimes Even less than the fossil fuel alternative. They can make organic material, they can make chemicals using carbon dioxide cheaper than the traditional way. They are actually making sustainable aviation fuel today is still a bit more expensive, but we actually see a viable pathway to really drive down the cost so that they can be competitive one day. So you don't need a carbon price. If we look at electric vehicle, lithium battery, solar and wind, they are now competing head to head with the fossil fuel alternative. And then if we look at what are still happening in the laboratory, these guys are probably the next wave. So if we get waves and waves of waves of these emerging low carbon technologies, then we are really pushing the decarbonization agenda forward. That really excites us.
- [13:01]
Sherrell Dorsey, TED Tech Host
It excites me that you're excited about this, because I think I probably speak for everyone who's listening in now that we can hear just the enthusiasm and the possibility and the opportunity. And I think so far in this space it's felt so out of reach to really solve these major challenges. So how do you envision Tencent leveraging some of your strengths in AI and data and cloud computing, particularly for this space of advancing carbon removal and emissions reductions and really speaking to some of those solutions that you're excited about?
- [13:38]
Dr. Xu Hao, Tencent VP of Sustainable Social Value
Yeah, so we just talked a lot about kind of physical low carbon technology. Right. As a technology company, the other half is sort of digital technology. So our approach is see how we can leverage the digital technology to actually either help the hardware made sectors be more effective, efficient, most likely, in many of the cases, being more efficient is actually being lower carbon for them, simply because energy actually is a big part, big share of their operating cost, or using digital technology, doing something you can't actually do without it. So conceptually, digital technology actually improves the ability to doing everything much more granular. If I'm an operator in a plant with digital capability, you can do almost everything in the split of a second. Nowadays with the development of AI machine learning, you can almost envision that all the plants will be running much more granular, which means the management of the plant will be much more efficient. As a result, they will produce same amount of output using much less resources. So we call it resource productive operations. And then with a lot of the innovation in the digital space, then you can achieve additional things. For example, there is the concept called virtual power plant. So with more renewable on the grid, flexibility becomes a scarce resource. So we get flexibility, for example from batteries or energy storage facilities. But that causes a lot of capex. You need to buy a lot of Batteries to put it on the grid so that you are flexible. But then you can try to match the generation and the production of the electricity and the use of the electricity more precisely so that you actually need less battery. So that is so called virtual power plant. Virtual means if I want you to so called generate, the user actually use less. If I want you to consume, then the user use more. That can almost only be done by digital technology because we really need a lot of data, a lot of optimization and also split of second reactions. So that cannot be done manually, can only be done digitally. That's only one example. We have so many examples on similar approach. So that is also a big part of the innovation space. And then finally, of course we have to solve the additional energy consumption as a result of all the development of digital technology. More data centers, more electricity consumption. But the solution is already out there. We just use more renewables. Right. So like at Tencent we have this policy saying okay, any additional energy we use we will use on renewables and any renewable we actually get what we use renewables on additional renewable projects. So we're not only pushing our own decarbonization agenda, we also want to help the renewable industries to get more capacity in the grid.
- [16:55]
Sherrell Dorsey, TED Tech Host
Yeah, and I think that's important to highlight because there is a growing concern about the emissions and the energy utility of the data centers and also where they are being established, how that's disruptive to the environment. I think from a physical social aspect. But then of course because of all of the growing needs of energy consumption, so pointing to renewables and usage is very prescient. What do you believe is the role of corporations like Tencent in the climate movement today, regardless of their business model or their product?
- [17:30]
Dr. Xu Hao, Tencent VP of Sustainable Social Value
There is a fairly straightforward or simple logic to this. If we look at almost anything, right? So any solution that solve big social or sustainability issues in the very long run will generate business value sooner or quicker. Tencent, we started with social network. So at that time it's actually a social issue. Because if we actually connect people more efficiently, you create a lot of social value. Right. I guess the a bit different with the normal business is that at the moment you're probably focusing on how do we create sustainability value first and then try to capture the business value at a later time. And then the timescale may not be three to five years where technology company used to, maybe five to 10 years. But if you have that vision or you have that patient, and I think we'll get there. So that's why tencent or like many of our peers are all doing very similar things. So I think it's based on that belief.
- [18:39]
Sherrell Dorsey, TED Tech Host
Tencent has a massive customer base and you mentioned that your video games can have an impact on climate education and advocacy. So can you speak more to this in the realm of learning?
- [18:52]
Dr. Xu Hao, Tencent VP of Sustainable Social Value
When we start this right, number one, we have our own decarbonization agenda. As a result, we need to not only make our data center more efficient by renewables, we still have scope 3 emissions so that we have to leverage carbon credit. So when we tap into the carbon credit world, we see, okay, a lot of the work is actually protecting some of the ecosystem. And then we realize that in many of our games, the theme of the game actually fits this topic very well. Because one of the heroes, one hero, his background may be he's the son of the forest. The other hero may be guardian of the frozen world. Or maybe some game is about apocalypse, climate change world. So that make us naturally think, okay, can we leverage some of these themes with the young players in the gaming world, with the work we actually supporting in the physical world? So that brings us to this idea, okay, can we integrate some of the real knowledge and real climate change elements into our games? So that's why we actually tried earlier this year in Southeast Asia. Is that one of our games? We're just about to launch a new hero. This hero is actually the son of the forest. So he grow up in the forest. He is friends with all the animals in the forest and then they face challenges. So we say, okay, in that region we face a lot of actual challenge. The mangroves, the peatland, the biodiversity in the sea. And then that's why we integrated a lot of these topics into the gaming world. And we also promised to the players, if you do this and that, finish all the tasks in the game, we will actually on your behalf, protect all of those ecosystem and forest. And then we just want to give it a try. And it turns out that over two, three weeks we got like 20 million plus players actually participated that make us really exciting because that's a pathway to the young generation deliver the message the way they like. And it's not boring, right? I guess another good thing we found out everybody cares. It's not just China or Asia or Europe or America. Everybody cares. So we plan to do things similar things like in older games in parts of the world, because everybody really cares. It's a topic that resonates to our everyday life.

Sherrell Dorsey, TED Tech Host
As we look ahead, let's say to 2030, is there one specific technology that you think is really going to move the needle on climate change?
- [24:15]
Dr. Xu Hao, Tencent VP of Sustainable Social Value
For our decarbonization journey. We're going to ratify our commitment by 2030 to be carbon neutral. But we won't stop there because we also committed to be net zero, which is more strict version of carbon neutral because we're going to try to reduce all the emissions we possibly can using whatever technology that can be applied. So our own decarbonization journey won't stop at 2030. We're going to continue to push through. So we will also try to push the major low carbon technology forward. So at the moment I think what really is already have a real pathway is everything around electricity. So we have renewables, which is cheaper than fossil fuel. We have storage that can electrify our transportation. And then we have new technology in the energy storage space that we can make our grid flexible so more renewable can be accommodated. And then we have heat pumps that can also decarbonize a lot of our buildings in terms of cooling or district heating. So the whole electrification, renewable energy transition is already there. I think we are pretty sure that it's going to scale up. And then I guess the question is what is the second wave? So I believe the second wave is in the so called hardware based sectors, right? It's iron, steel, cement, chemicals, paper and pulp and many other aluminum, many of. Because these guys are begin to have more and more options to actually decarbonize their production. Five years ago I think there are limited options like for iron steel, you probably can produce steel from scrap, but you only have this much scrap available. But today you can use hydrogen or you can use bell char. There are more and more technology available. So what I'm really excited is this next round of decarbonization technology. They are designed to be carbon neutral or net zero from the very beginning. I think by 2030 many of them will be much cheaper and much more scalable. So that we will see maybe the first generation or the second generation of low carbon technology unicorns grow out of China or anywhere in the world. That will really give us confidence that decarbonization can be achievable. I don't want to bet on any single technology, but I think that group of technology will eventually be there.
- [27:04]
Sherrell Dorsey, TED Tech Host
I'm also curious about it as our kind of last question as we close out here, what are you worried about? You know, there's this great vision for 2030, all of these hopeful opportunities, but obviously there are potential roadblocks, potential challenges. How you're thinking or considering some of those challenges and those hurdles that are gonna need to be overcome in order to realize this vision.
- [27:30]
Dr. Xu Hao, Tencent VP of Sustainable Social Value
So the challenges we face is, number one, I think we don't really know the right answer, right? So that's why. Also why I don't want to bet on any single technology because I don't know who will be the final winner. Someone will say, okay, we will get nuclear fusion in 20 years. And then we don't need all of these solutions because we get unlimited energy for everyone and without any emission, we just use hydrogen. We just use nuclear fusion, right? We have almost unlimited nuclear fusion, raw material to actually deliver the energy. But what if it doesn't? Or we might bet on CCOs or might bet on hydrogen, but what if it doesn't materialize? So I think that's the challenging part, is we don't know the right answer, but we don't have time to find out the right answer and then scale up that single right answer. So that's why we need to push all the possibility forward, which makes, I guess, everybody nervous. It makes. Makes me really nervous.
- [28:38]
Sherrell Dorsey, TED Tech Host
I appreciate the candor, Dr. Howell, and thank you so much for joining me here today. I'm excited for the goals that you all have set, but I think also the. The vision in the world that you've painted that allows us to understand that it's. It's going to be a challenge, right? And that's what hard things are about. And figuring this out, we're doing something very new. And yet there's a world full of possibility, which also means that all hands are on deck and everyone's talents can be put to use here.
