Reading Passage: Blockchain Technology and Global Emissions

Level: Medium Text

Blockchain technology, originally devised for the digital currency Bitcoin, has evolved into a robust tool for various applications, including tracking global emissions. This decentralized ledger system offers transparency, immutability, and traceability, which are critical for monitoring and reducing global carbon footprints.

Countries and organizations worldwide recognize the urgency to address climate change. Traditional methods of tracking emissions often suffer from inaccuracies and fraud. Blockchain technology introduces a transformative approach by enabling real-time, tamper-proof recording of emissions data.

Blockchain Emissions Tracking

For instance, IBM and Energy Blockchain Lab in China collaborated to create a blockchain-based platform that monitors carbon footprints. The system records the carbon emissions data of companies, making it publicly accessible and transparent. Such advancements ensure accountability and foster an environment where organizations are encouraged to adhere to environmentally friendly practices.

Moreover, blockchain’s interoperability allows it to integrate with other technological systems, such as the Internet of Things (IoT). IoT devices can collect emissions data from various sources, and blockchain can securely store and analyze this data. This integration can lead to more accurate and comprehensive monitoring.

In summary, blockchain technology holds significant promise in the fight against climate change by offering a secure, transparent, and efficient means to track and reduce global emissions.

Answer Keys

1. b. It provides transparency and immutability.
   Explanation: Blockchain technology’s transparency and immutability are primary benefits for tracking emissions, as these features ensure data integrity and public accessibility.

2. b. It makes carbon emissions data publicly accessible.
   Explanation: The system developed by IBM and Energy Blockchain Lab provides a transparent platform where carbon emissions data can be accessed by the public, fostering accountability.

3. False
   Explanation: Blockchain technology was initially developed for digital currencies like Bitcoin, not for environmental data monitoring.

4. False
   Explanation: IoT devices can indeed be integrated with blockchain systems for more accurate emissions tracking.

5. • A – iii. All data is openly available (Transparency)
   • B – ii. Data cannot be altered once recorded (Immutability)
   • C – i. The ability to work seamlessly with other systems (Interoperability)

Common Mistakes

1. Misinterpreting Key Features: Ensure you understand the unique characteristics of blockchain like immutability and transparency.
2. Overlooking Integration Capabilities: Remember that interoperability is a significant feature that allows blockchain to work with IoT devices.
3. Confusion Between True and Not Given: Only mark True if the passage explicitly states the information; if uncertain, Not Given is more appropriate.

Vocabulary

1. Decentralized (adj): /ˌdiːsɛntrəˈlaɪzd/ – Not controlled by a single central authority.
2. Immutability (n): /ɪˌmjuːtəˈbɪlɪti/ – The quality of being unchangeable.
3. Interoperability (n): /ˌɪntəˌɒpərəˈbɪlɪti/ – The ability of computer systems or software to exchange and make use of information.

Grammar Points

1. Passive Voice: Often used to focus on an action rather than the subject performing the action. Example: “The carbon emissions data is recorded.”
2. Complex Sentences: Utilizing subordinating conjunctions to join clauses for more detailed communication. Example: “Although blockchain was initially developed for Bitcoin, it has expanded to other applications.”

Recommendations

• Practice Regularly: Consistency is key. Divide your reading practice into manageable chunks and practice daily.
• Use Authentic Materials: Rely on sources like academic journals, news articles, and previous IELTS materials for practice.
• Focus on Weak Areas: Identify and improve your weak points, whether it’s vocabulary, grammar, or certain types of questions.
• Vocabulary Building: Learn and use new words in your writing and speaking to enhance fluency and comprehension.

Embark on your IELTS journey with confidence by integrating these reading practices into your study routine. Good luck!
