The Carbon Footprint Of Generative AI: How It Impacts The Environment

Imagine you’re assigned a task that needs intense research and data compilation for a project with an engaging presentation. Manually, this task could take days, but with advanced generative AI tools, what once seemed overwhelming can be done in minutes.

But with such advanced technology and ease comes a hidden cost – the massive energy consumption required to run such AI models. As the popularity of such tech skyrockets, so does the carbon footprint of generative AI. It raises critical questions like what is AI’s environmental impact, and how can we make it more sustainable?

In this post, I will discuss what generative AI is and its carbon footprint. We will also focus on the AI carbon footprint calculator and potential measures to reduce the environmental impact. We will also look at some of the data on generative AI energy consumption.

First of all – What is Generative AI

Most of us have used generative AI at some point, and its impact on productivity and creativity is hard to ignore. But what exactly is it? 

Generative AI or Gen AI is widely used for generating compelling content and unique images, preparing presentation designs, videos, code, or any other AI powered assistance – generative AI tools can do them all. It is powered by deep learning models that imitate human learning by identifying patterns in datasets. This enables the AI tools to respond intelligently to user prompts. 

Some of the popular generative AI tools are – ChatGPT, Dall-E, GPT-4, Gemini (previously Bard), and GitHub Copilot, among others. 

Apart from generating content, what is GenAI used for? Check out these innovative use cases for specifically tailored content it can generate. 

Since OpenAI’s ChatGPT launch in 2022, generative AI tools have gained global attention, especially on the technology, marketing, and business fronts. The future possibilities are profound – from enhancing business ideas to transforming the healthcare sector -Gen AI is here for the long haul.

But this rapid AI tech adoption comes at an adverse environmental cost. Large language models (LLM) have become very prevalent today (ChatGPT) and require enormous computational power, resulting in a high carbon footprint of generative AI. 

What is the Carbon Footprint of Generative AI?

As we probably know, the carbon footprint is the total amount of greenhouse gases, primarily carbon dioxide, along with methane, nitrous oxide, and others, emitted by manufacturing industries, power plants, etc. It is measured in tons of CO₂ equivalent (CO₂e). Moreover, these greenhouse gasses are the major contributors to global warming and climate change that we see today. 

For AI, the carbon footprint reflects the energy consumed to run and train models and the process of building, deploying, and maintaining the entire hardware set-up. 

According to stats compiled by Akepa, training advanced generative AI tools, like GPT-3, produced 6,26,000 pounds of CO₂. If we compare the electricity usage, a single search or prompt on ChatGPT takes around 2.9 watt-hours of electricity – ten times more than a Google search. 

The Environmental Impact of Generative AI Tools

Let’s take a closer look at the adverse environmental impact caused by Gen AI:

Carbon footprint

• LLMs have high energy demands due to their complex, data heavy processes and advanced hardware, like GPUs. For perspective, streaming one hour of Netflix consumes about 0.8 kWh (kilowatt-hour) of electricity. While training GPT-3 consumes the energy equivalent of watching 1.6 million hours of Netflix – imagine the amount of power required to run such a model. 

• A recently published report by HPCwire predicts that by 2029, AI tools will account for roughly 1.5% of the world’s total electricity consumption, which is equivalent to powering millions of households.  

• AI models rely on data centers, which are energy-intensive facilities. According to the July 2024 report compiled by the Center on Global Energy Policy, these data centers will consume 14 GW (gigawatts) of power annually by 2030. 

Global warming and climate change

• The electricity powering these AI tools and data centers majorly comes from burning fossil fuels, which leads to environmental degradation, toxic gas emissions, and a high carbon footprint of generative AI.

• In one of the reports published by Morgan Stanley in September 2024, it is predicted that by 2030, the data centers will produce around 2.5 billion tons of greenhouse gasses globally. This is nearly triple the amount of carbon emissions that would have been without the rise of generative AI. 

• At this scale, global temperatures are bound to rise even more in the coming years. 

Resource depletion and e-waste generation

Apart from electricity, the data centers also rely on water and minerals. 

• Data centers require a lot of water to maintain the cooling systems and prevent hardware overheating. GPT-3 training models can consume nearly 700K liters of fresh water, which is enough to build 370 BMW cars or 320 Tesla vehicles. 

• The raw materials required to build and power AI are often mined from the earth in destructive ways, affecting the biodiversity of the region.

• As AI tech adoption continues, data centers may face pressure to scale up, potentially increasing the carbon footprint of generative AI. This further results in hazardous electronic waste in the environment. In October 2024, a study was published in the Nature Computation Science Journal. It stated that if the current trend continues, LLMs will likely generate 2.5 million tonnes of e-waste every year by 2030.

Impact of global tech giants

Major tech giants are contributing to the carbon footprint of generative AI while trying to keep their operations running smoothly: 

• Google: With the rise of AI, Google’s emissions increased nearly 50% from 2019 to 2023, posing a challenge for reduced carbon footprint. The U.S. data centers used around 12.7 billion liters of water in 2021 for cooling.

• Microsoft: Due to their investments in OpenAI and CoPilot, Microsoft’s emissions rose to 40% from 2020 to 2023. The CO₂e increased from 12.2 million tonnes to 17.1 million tonnes during this period.

• Meta: Scope 3 emissions increased by over 65% between 2020 and 2022 and contributed to nearly 8.4 million tonnes of CO₂e due to AI infrastructure. 

Potential risks for living organisms

• The burning of fossil fuels for electricity and other AI infrastructure results in massive air and soil pollution, which directly affects soil microbes, aquatic life, plants, and public health. 

• The generation of e-waste can also release toxic compounds into the environment, contaminating nearby water bodies and soil quality. 

• As the demand for generative AI grows, so does environmental degradation, putting all living organisms, including humans, at major risk from all the pollutants. 

It’s about time to explore and switch to renewable energy sources and curb environmental depletion before it’s too late. While AI has its own downside, it also plays a crucial role in providing various climate change solutions for a sustainable future. 

How to Reduce the Carbon Footprint of Generative AI 

Here are some potential strategies to reduce the carbon footprint of generative AI:

• Use efficient algorithms and hardware: The carbon footprint of generative AI, especially in LLMs, can be reduced with energy-efficient algorithms and hardware. Researchers from Google and the University of California have shown that LLMs can cut emissions by 100 to 1000 times without compromising on quality. 

• Use pre-trained models: Instead of training new generative AI models from scratch, companies can fine-tune the existing ones for specific tasks. It saves a lot of resources, time, and expenses and reduces energy consumption. 

• Opt for efficient model deployment: Techniques such as quantization, distillation, and client-side caching streamline the AI models’ deployment on devices with limited resources. 

• Shift to greener data centers: Companies can choose to shift their computational load to data centers that have implemented sustainable practices to mitigate the overall carbon footprint of generative AI. 

• Evaluating generative AI transparency: A multi-disciplinary team from MIT, Princeton, and Stanford developed the Foundation Model Transparency Index. It scores AI models on criteria such as carbon emissions during training and usage, resources used in data centers, and overall energy consumption right from its creation to usage. By encouraging transparency, these metrics push for greener AI and energy-efficient practices.

• Have stringent ethical guidelines: By implementing strong guidelines for AI and sustainability, ethics can help reduce the carbon footprint of generative AI. 

Implementing these strategies can be very beneficial to companies and businesses; here’s how:
