For UK/European rose lovers, a 2007 study by Cranfield University in England found that 12,000 Kenyan roses resulted in 13,200 pounds (6,000 kilograms) of CO2, while the equivalent number grown in a Dutch hothouse emitted 77,150 pounds (35,000 kilograms) of CO2.

However, that’s just the cost of growing and transporting them – roses also need watering and the use of pesticides in order to make them look as beautiful as possible. Also of concern is where the flowers are grown. Native forests and wetlands from all over the world have been displaced to make way for floral plantations, and the pesticides runoff has had a massive impact on local wildlife.

The report als mentioned the fuel needed to power the refrigerated trucks, not to mention the fact that refrigerant gases also exacerbate climate change.
