How much CO2 is in a can of soda?

Answered by James Kissner

A can of soda typically contains around 2-3 grams of carbon dioxide (CO2). This may sound like a significant amount, but when we put it into perspective, it is actually quite small compared to the overall human CO2 emissions.

To understand the significance of the CO2 in a can of soda, let’s look at the bigger picture. On average, a person in the UK is responsible for emitting around six tonnes of CO2 per year, which is equivalent to 17 kilograms per day. These emissions come from various sources such as transportation, energy production, and industrial activities.

When we consider that a can of soda contains only 2-3 grams of CO2, it becomes clear that the contribution of fizzy drinks to overall CO2 emissions is minimal. In fact, the CO2 released from consuming a can of soda is negligible compared to the CO2 emitted from other daily activities and lifestyle choices.

It is important to note that the CO2 emissions from fizzy drinks primarily come from the carbonation process. When carbonated drinks are manufactured, carbon dioxide gas is dissolved into the liquid under pressure. When the can is opened, the pressure is released, causing some of the CO2 to escape into the atmosphere. However, this is a small fraction of the total CO2 emissions associated with soda consumption.

While it is essential to be mindful of the environmental impact of our choices, focusing solely on the CO2 emissions from fizzy drinks would be overlooking more significant sources of emissions. Instead, it is crucial to address larger contributors to CO2 emissions, such as reducing reliance on fossil fuels, promoting renewable energy sources, and adopting sustainable transportation methods.

A can of soda contains a small amount of CO2, typically around 2-3 grams. However, when considering the overall human CO2 emissions, this contribution is insignificant. To tackle climate change and reduce CO2 emissions, it is crucial to address larger sources of emissions rather than focusing solely on fizzy drinks.
