In an exclusive interview, Annareddy speaks about the inspiration behind Cero Hero, the challenges of driving behavioral change, and his vision for the future of sustainability metrics.
Sri Saiteja Annareddy, founder and CEO of Cero Hero, is building a platform designed to make climate action simple, measurable, and rewarding. With a background in blockchain and product-focused startups, Annareddy has long focused on improving transparency and efficiency in real-world systems. His earlier ventures, including Chakravuyha and DLT Labz, laid the groundwork for his current work in sustainability and climate technology.
At Cero Hero, Annareddy is developing a system that transforms everyday behaviors into verifiable climate actions. The platform aggregates thousands of micro-offsets, from daily lifestyle choices, and converts them into authenticated climate credits. These are issued as non-transferable Cero Credits, linked to each user’s unique Cero ID, and can be redeemed with partner brands as verified carbon dioxide (CO2) reductions.
Cero Hero aims to demonstrate that small, consistent actions, when scaled across individuals, can generate meaningful environmental impact.
Before launching Cero Hero, Annareddy served as COO at Enverified, where he worked on carbon-neutralization frameworks for cities and enterprises. He has also collaborated with organizations such as EESL on energy-efficiency programs aimed at expanding sustainability efforts across communities.
With Cero Hero, his focus has shifted toward empowering individuals, bringing climate accountability down to the personal level while leveraging technology to track, verify, and incentivize sustainable behavior.
In an exclusive interview, Annareddy tells The American Bazaar about the inspiration behind Cero Hero, the challenges of driving behavioral change, and his vision for the future of sustainability metrics.
The American Bazaar: For those new to Cero Hero, how would you describe what the platform does?
Sri Saiteja Annareddy: If you ever have an ID for climate or sustainability recording, that is Cero Hero. It is an ID that records your climate-positive actions. And we wanted to create this as a passport for sustainability.
What inspired you to start Cero Hero? What problem were you trying to solve?
I had a lot of passion to do something for climate change, but I couldn’t continue consistently. I would feel motivated one day, take action, and then stop. That was the starting point.
Also, many of us—almost 90 percent—don’t know our individual carbon footprint. If we did, we would probably make different choices. We might reduce consumption or change habits in ways that suit each individual. But so far, no one has really brought that awareness to the individual level.
We wanted to bring that into the limelight and show that it’s not always governments or large corporations that drive impact. When individuals take small actions and those actions are multiplied by millions, it can create a huge impact. That’s what Cero Hero is doing right now. So, the idea is that individuals collectively can create impact at scale.
Right now, we are working with some universities where it is compulsory for students to be on Cero Hero, and their participation is even considered as part of their curriculum.
What challenges do you see in getting people or companies to adopt more sustainable habits?
I always believe that it’s not just GDP or financial assets that matter, we should also think about natural capital. Right now, none of us really has natural capital. In that sense, we are all poor.
So, the question is: how do we motivate people to think in terms of natural capital? If we can do that, it reduces pressure on the planet, lowers consumption, and changes behavior overall.
Every action has an impact. It’s not about eliminating carbon entirely—we need carbon. But the issue is overconsumption. So how do we motivate and educate people to act differently? That is what Cero Hero is trying to address.
What role do you see technology playing in making climate action easier and more accessible?
Technology plays a key role, it’s essential. Without technology, something like Cero Hero wouldn’t be possible.
Our core belief is that innovation needs to be centered around sustainability. In the past, most technological advancements were driven by convenience. People built things because they needed them, without considering environmental impact.
Now that mindset must change. Sustainability needs to come first, and convenience should follow. When that happens, we see innovations like biodiesel, electric transport, and green energy emerging without damaging the environment.
One of the challenges we faced early on was engagement. When we conducted seminars, people were enthusiastic in the moment, but they wouldn’t stay consistent afterward. That’s human nature.
So, we introduced blockchain technology. Every action is recorded on the blockchain, creating a kind of sustainability score—similar to a financial score or even an immigration score. When people see that their actions are being recorded and can lead to long-term benefits, it motivates them to stay consistent.
Technology helps us create that accountability and incentive structure.
Have you seen any interesting use cases or success stories recently?
Recently, we concluded a pilot with RTA Dubai. We worked with RTA Marine, you might be familiar with the one-dirham boats. While they already have climate-positive initiatives, diesel consumption still results in significant emissions.
We focused on something simple: changing the behavior of drivers. By doing that, we saw more than a 40 percent improvement in emissions reduction. That has been one of our biggest successes so far.
We are also working with BITS Pilani Dubai campus to create a roadmap for achieving net zero. We are engaging students and helping them understand how to reach that goal.
What is your vision for where Cero Hero can go next, regionally or globally?
I believe that in the next five to eight years, sustainability will become much more mainstream.
At that point, metrics like sustainability scores could become part of everyday decision-making. For example, when a bank evaluates you for a credit card, they look at your financial score. Similarly, organizations and institutions may start looking at your sustainability score.
We see the Cero ID becoming a standard way to determine whether someone is a sustainable citizen. People might carry their Cero ID as proof of their sustainability efforts.
Is there anything else you would like readers to know?
I wouldn’t say I’m someone who gives big lectures on leadership, but I can share something from my experience.
We all have big goals, but sometimes unexpected challenges may arise, and we feel like giving up. My suggestion to entrepreneurs is to break those big goals into smaller parts. Focus on small, achievable impacts and keep moving forward.
Don’t give up on the entire journey. Difficult times are temporary. You may not be able to control external factors, but you can stay consistent. When the timing aligns, success will follow.
