Are you thinking about saying I love you with a dozen roses this year?
You’re not alone. Valentine’s Day is the biggest day of the year for most florists and rose growers. American shoppers are expected to spend nearly $2 billion on flowers — most of which will be roses — this Valentine’s Day. But are roses a green gift in 2020?
Apologies to all the rose lovers out there. However the answer is that, unfortunately, roses aren’t green.
So that may be surprising. After all, flowers are natural and compostable. But when we examine climate and flowers, the biggest issue is consequently transportation. Valentine’s Day occurs in the middle of winter for most of the U.S.. So Valentine’s Day bouquets have to travel a long way. Especially to get to your loved one’s arms.
Most of the roses given for Valentine’s Day in the U.S. come from overseas and, particularly, Latin America– especially Colombia and Ecuador, the world’s second- and third-largest exporters of cut flowers after the Netherlands. In fact, Colombia alone shipped more than 4 billion flowers to the U.S. in 2018.
In total, it’s estimated that more than 15,000 tons of flowers are delivered in less than a month to fill Valentine’s bouquets from Ecuador alone. And, because roses are particularly fragile, they have to be flown and trucked in temperature-controlled planes and trucks which has significant consequences for the climate.
The International Council on Clean Transportation estimated that Valentine’s flower delivery flights burn approximately 114 million liters of fuel, emitting nearly 360,000 metric tons of carbon dioxide into the atmosphere.
While we often think of dirty, polluting fossil fuel plants as the main driver of carbon pollution, Transportation is actually the largest source of greenhouse gas emissions in the United States, comprising 29 percent of the country’s total emissions with approximately one quarter of those U.S. transportation emissions come from freight.
