Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair: 
Instruction: Write a brief summary of the main points in this text about Axiom Space's second private mission to the International Space Station.

Here's the source text:
Axiom Space is ready to launch its second-ever private mission to the International Space Station today (May 21), a flight that will mark a series of spaceflight firsts.

The 10-day Ax-2 mission to the International Space Station has been cleared for launch, representatives from Axiom Space, NASA and SpaceX said Saturday (May 20) after completing one final launch readiness review. Liftoff is set for 5:37 p.m. (2137 GMT) on a SpaceX Falcon 9 rocket and Dragon capsule, which will launch from Pad 39A of NASA's Kennedy Space Center in Cape Canaveral, Florida.

"It's obviously a very, very exciting day," Derek Hassmann, Axiom Space chief of mission integration and operations, told reporters in a teleconference this evening. "We worked a long, long time in collaboration with our partners at SpaceX and NASA to get to this point. The crew has been working very hard to get trained and they're certainly ready to go."
Response: On May 21, Axiom Space is scheduled to launch Ax-2, its second private mission to the International Space Station. Representatives from Axiom Space, NASA, and SpaceX conducted a final launch readiness review and approved the launch. The SpaceX Falcon 9 rocket and Dragon capsule are planned to launch from NASA's Kennedy Space Center in Florida. The space mission is scheduled for 10 days and involves several unprecedented events in space exploration. The mission has been planned and executed after thorough preparation and cooperation among all the parties involved.

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.

Briefly summarize the key points made in the following text about different strategies used by tech companies to reduce their carbon footprint and promote environmental sustainability:  

As the urgency of tackling climate change intensifies, major tech giants are taking diverse approaches to reduce their environmental impact and support sustainability initiatives. Google has committed to operating entirely on carbon-free energy by 2030 and is investing heavily in renewable energy projects globally. Microsoft aims to be carbon negative by 2030, removing more carbon from the environment than it emits through advanced carbon capture technologies.

Apple has doubled down on energy efficiency, aiming to make every Apple device carbon neutral by 2030. It is transitioning its entire supply chain and manufacturing to renewable sources. Amazon is pledging to power all operations with 100% renewable energy by 2025 and has ordered 100,000 electric delivery vehicles. 

Beyond their own operations, these companies are funding reforestation projects, developing AI solutions for environmental challenges, and providing green cloud computing services. Partnerships with NGOs and stakeholder activism are driving greater accountability. However, critics argue that tech's environmental actions are still insufficient compared to their massive carbon footprints and rapid growth trajectories.

The passage highlights various strategies adopted by major tech companies to reduce their environmental impact. Google plans to run entirely on carbon-free energy by 2030 through renewable investments. Microsoft aims to go carbon negative by 2030 using carbon capture tech. Apple targets carbon neutrality for devices and supply chain by transitioning to renewables. Amazon committed to 100% renewable operations by 2025 and ordered electric vehicles. Beyond operations, companies fund reforestation, develop green AI/cloud solutions, and face stakeholder pressure for accountability, though critics argue efforts are inadequate relative to their massive carbon footprints.
