The digital world has a physical footprint. From optimizing SQL queries to reduce CPU cycles to choosing data centers powered by renewable energy, sustainability is becoming a key metric for tech teams.

**The Carbon Footprint of Software:**
Software consumes energy at every stage of its lifecycle: development, deployment, and use.

**Writing Energy-Efficient Code:**
- **Optimize Algorithms**: Choose efficient algorithms to reduce CPU usage.
- **Minimize Data Transfer**: Reduce the amount of data transferred over the network.
- **Use Caching**: Cache frequently accessed data to reduce database queries.
- **Optimize Images and Videos**: Compress media files to reduce data usage.

**Green Hosting:**
- **Renewable Energy**: Choose hosting providers that use renewable energy.
- **Data Center Location**: Choose data centers located in regions with low carbon intensity.
- **Server Efficiency**: Choose servers with high energy efficiency.

**Sustainable Development Practices:**
- **Remote Work**: Reduce commuting emissions by working remotely.
- **Digital Documentation**: Use digital documentation instead of printed materials.
- **E-Waste Management**: Recycle old electronics properly.

By implementing these practices, tech teams can reduce their carbon footprint and contribute to a more sustainable future.
