Definition

What is it?

Carbon sequestration is the process of capturing and storing carbon dioxide (CO2) from the atmosphere. It helps to reduce the amount of greenhouse gases, which are a major cause of climate change and global warming.

Simple Example

Quick Example

Imagine your family has a small garden. When you plant trees and plants, they absorb CO2 from the air to grow. This is like a natural way of carbon sequestration, storing carbon in the plants and soil, similar to how your piggy bank stores your pocket money.

Worked Example

Step-by-Step

Let's say a power plant releases 1000 tonnes of CO2 every day. A new carbon capture technology is installed that can capture 70% of this CO2. How much CO2 is captured daily?

Step 1: Identify the total CO2 released = 1000 tonnes.
---Step 2: Identify the capture percentage = 70%.
---Step 3: Convert the percentage to a decimal = 70 / 100 = 0.70.
---Step 4: Multiply the total CO2 by the capture percentage (in decimal) to find the captured amount = 1000 tonnes * 0.70.
---Step 5: Calculate the result = 700 tonnes.

Answer: 700 tonnes of CO2 are captured daily.

Why It Matters

Understanding carbon sequestration is crucial for fighting climate change, which impacts everything from our weather to our food supply. It's key for careers in Climate Science, Engineering sustainable solutions, and even developing new FinTech models for carbon credits.

Common Mistakes

MISTAKE: Thinking carbon sequestration is only about planting trees. | CORRECTION: While planting trees is a natural method, carbon sequestration also includes many technological methods like capturing CO2 directly from industrial emissions and storing it underground.

MISTAKE: Believing carbon sequestration permanently removes all carbon from the environment. | CORRECTION: It's about capturing and storing CO2 to reduce its concentration in the atmosphere, but the storage needs to be long-term and secure, and it doesn't remove ALL carbon forever.

MISTAKE: Confusing carbon sequestration with carbon emissions. | CORRECTION: Carbon emissions are the release of CO2 into the atmosphere, while carbon sequestration is the process of REMOVING and STORING that CO2.

Practice Questions

Try It Yourself

QUESTION: A forest absorbs 50 tonnes of CO2 per year. If a new plantation doubles the forest area, how much CO2 will be absorbed in total per year? | ANSWER: 100 tonnes (50 tonnes * 2)

QUESTION: A factory currently emits 1200 kg of CO2 per hour. If a carbon capture system is installed that reduces emissions by 25%, how much CO2 will still be emitted per hour? | ANSWER: 900 kg (1200 kg * 0.75 or 1200 kg - (1200 kg * 0.25))

QUESTION: An agricultural field can sequester 15 tonnes of carbon per hectare per year. If a farmer has 10 hectares and implements practices to increase sequestration by 20%, how much total carbon will be sequestered in a year? | ANSWER: 180 tonnes (15 tonnes/hectare * 10 hectares = 150 tonnes. 150 tonnes * 1.20 = 180 tonnes)

MCQ

Quick Quiz

Which of the following is an example of natural carbon sequestration?

Capturing CO2 from factory chimneys

Planting more trees in a forest

Storing CO2 in underground rock formations

Using special filters to clean vehicle exhaust

The Correct Answer Is:

Planting trees is a natural process where plants absorb CO2 from the atmosphere. The other options describe technological or engineered methods of carbon sequestration.

Real World Connection

In the Real World

In India, projects like the 'Green India Mission' are working to increase forest cover, which is a massive natural carbon sequestration effort. Scientists and engineers are also exploring ways to use advanced technologies, similar to how ISRO develops new rockets, to capture CO2 from industries and store it safely, helping our cities breathe cleaner air.
