Today is Earth Day, and Apple is celebrating the occasion in five ways.
First, Apple has updated its home page to highlight its ongoing Apple 2030 initiative. Apple is aiming to become carbon neutral across its entire business, manufacturing supply chain, and product life cycle by 2030. Last week, Apple announced that it surpassed a 60% reduction in its global greenhouse gas emissions compared to 2015 levels. More details are available in the company's 2025 Environmental Progress Report.
Second, Apple recently launched an Earth Day promotion that offers customers 10% off eligible Apple accessories when they recycle eligible devices at participating Apple Stores. The offer is available through May 16 in the U.S. and many other countries. For more details about the promotion, read our earlier coverage.
Third, the annual Earth Day Activity Challenge has returned. Apple Watch users who complete any workout for 30 minutes or longer today will receive a 2025 Earth Day award in the Activity app, along with animated iMessage stickers.
Fourth, Apple plans to enable Clean Energy Charging on iPhone and iPad demo units in U.S. stores. With this feature, the devices will charge at times of the day when the electric grid is relatively cleaner, as much as possible.
Finally, Apple is celebrating Earth Day with content across some other apps and services. For example, Apple Fitness+ subscribers can listen to a new Time to Walk episode featuring actress and climate advocate Shailene Woodley.

As for CO₂ being “plant food”, while it's true that CO₂ is a raw material for photosynthesis, the benefits of elevated CO₂ levels on plant growth are complex and not uniformly positive.
Some plants, particularly C₃ species like wheat and rice, may exhibit increased photosynthesis under higher CO₂ concentrations. However, this response can be limited by other factors such as nutrient availability, water supply, and temperature.
Elevated CO₂ can reduce the nutritional content of crops. Studies have shown declines in protein, iron, and zinc levels in staple crops like wheat and rice when grown under higher CO₂ conditions.
Plus, since increased CO₂ contributes to global warming, this leads to more frequent heatwaves, droughts, and extreme weather events, which can negatively affect crop yields and food security.
