AI has a climate problem — but so does all of tech
We’ve been talking about AI a lot on Decoder lately; it’s unavoidable. But there’s one piece of feedback we’ve gotten that I really wanted to spend some time on: how the lightning-fast explosion of AI tools affects the climate.
After all, to run AI at scale, we need to build a lot of data centers and pack them full of power-hungry GPUs. That takes a lot of energy, and whether using all that juice is worth it comes up frequently when we talk about AI. It’s both a matter of practical concern — “can our aging grid support all of this?” — and a moral objection — “we shouldn’t build these systems because they’ll wreck the planet.”
What’s particularly complicated is that big tech companies like Amazon, Google, and Microsoft have spent the last few years working with governments around the world to set ambitious goals around sustainable energy usage so that we might slow the rate of climate change to simply “bad” instead of “catastrophic.” But now, with AI, all of those companies are blowing past their emissions targets and are actually getting worse over time. That’s not great.
But putting a bunch of computers in a data center and running them at full tilt is how basically everything works now. If you have a moral objection to AI based on climate concerns, you might have a moral objection to TikTok and YouTube as well, which are constantly ingesting and encoding millions of hours of video. You might have a moral objection to video games, which run both on power-hungry GPUs in people’s homes and often require intense data center workloads for online multiplayer. And I’ll take a guess, but I feel pretty certain anyone with climate concerns about AI has a pretty harsh assessment of crypto, too.
I mean, think about it this way: the Nvidia H100, which is the gold standard for AI GPUs, is pretty similar to the gaming-focused Nvidia RTX 4090 in terms of power draw. What framework should we use to evaluate the climate impact of those cards and how we feel about how they’re used?
It’s messy and complicated, and there are a bunch of apparent contradictions along the way. So it’s perfect for Decoder. To help sort it out, I’ve invited Verge senior science reporter Justine Calma on the show to see if we can untangle this knot. Let us know how we did.

The concerns you've raised highlight a significant challenge in balancing technological advancement with environmental sustainability. Here are a few potential solutions and considerations to address the climate impact of AI and tech in general:
### 1. **Increase Energy Efficiency**
- **Develop Energy-Efficient Hardware**: Encourage manufacturers to design and produce more energy-efficient GPUs and CPUs. This includes optimizing architectures for lower power consumption without sacrificing performance.
- **Optimize Data Center Operations**: Implement advanced cooling systems, better airflow management, and energy-efficient server hardware. Google, for example, uses AI to optimize cooling in its data centers, reducing energy consumption.
### 2. **Transition to Renewable Energy**
- **Power Data Centers with Renewables**: Major tech companies can commit to sourcing 100% of their energy from renewable sources like wind, solar, and hydroelectric power. Some companies are already moving in this direction, but it needs to be scaled up.
- **Energy Storage Solutions**: Invest in and develop better energy storage solutions to store renewable energy, ensuring a steady supply even when the sun isn't shining or the wind isn't blowing.
### 3. **Improve Software Efficiency**
- **Algorithm Optimization**: Optimize AI algorithms to be more energy-efficient. This could involve developing techniques that require fewer computations or use less power-intensive methods.
- **Efficient Coding Practices**: Encourage developers to follow best practices for writing efficient code, which can reduce the computational resources needed.
### 4. **Carbon Offsetting and Negative Emissions Technologies**
- **Invest in Carbon Offsetting**: Companies can invest in projects that offset their carbon emissions, such as reforestation, carbon capture, and storage technologies.
- **Develop Negative Emissions Technologies**: Support the development and deployment of technologies that actively remove CO2 from the atmosphere.
### 5. **Regulation and Policy**
- **Government Policies**: Governments can implement regulations that mandate energy efficiency standards and renewable energy usage for tech companies. They can also offer incentives for companies that achieve significant reductions in their carbon footprints.
- **Carbon Pricing**: Introduce carbon pricing mechanisms to make emitting CO2 more expensive, incentivizing companies to reduce their emissions.
### 6. **Corporate Responsibility and Transparency**
- **Set Ambitious Sustainability Goals**: Companies should set and publicly commit to ambitious sustainability goals, with clear timelines and regular reporting on progress.
- **Transparent Reporting**: Increase transparency around energy usage and carbon emissions, allowing stakeholders to hold companies accountable.
### 7. **Public Awareness and Advocacy**
- **Consumer Choices**: Educate consumers about the environmental impact of their technology usage, encouraging more sustainable behavior and choices.
- **Advocacy for Sustainable Tech**: Support advocacy groups pushing for sustainable technology practices and policies.
### Conclusion
Addressing the climate impact of AI and tech requires a multifaceted approach involving technological innovation, policy changes, corporate responsibility, and consumer awareness. By working together, governments, companies, and individuals can mitigate the environmental impact of technology while still benefiting from its advancements. |
