Sustainability is a key theme this year at the annual CES tech trade show in Las Vegas. Agriculture tech is on full display on the show floor while companies big and small also showcase their green innovations and initiatives. That includes Volvo CEO Martin Lundstedt's vow to reach net-zero emissions by 2040 and Wisconsin-based OshKosh Corporation's electric fire engines and garbage trucks. John Deere also unveiled a fleet of fully autonomous equipment like tractors that are already in use on some farms and orchards. Some experts say AI is key to the industry's future as climate change makes farming more unpredictable.
