Brewing climate change? What your morning joe means for a warming world
Global News
Climate change has impacted global coffee production but research also suggests that your caffeine consumption could be contributing to extreme weather events.
A brewing climate crisis may be coming after your morning joe, with new research suggesting that global coffee production faces an “increasing challenge” from extreme weather events.
A study published in the PLOS Climate journal on March 8 showed that climate change has resulted in sub-optimal growing conditions — heat waves, droughts, frosts and floods — which means coffee production can expect “ongoing systemic shocks.”
That release follows research earlier this year that also suggested the way you prepare your coffee and your consumption habits could be contributing to climate change.
Researchers at the University of Quebec analyzed the amount of carbon emissions from four different coffee preparation methods.
They used life cycle assessment which helps translate production into pollution, with data on machine manufacturing, capsules, packaging and emissions related to the agricultural phase.
A final version of their study is yet to be published but they shared part of that scientific paper in an article on The Conversation in January.
They found that drip filter coffee had the highest carbon emissions because a higher content of ground coffee is used to prepare the drink and it also uses up more electricity.
In their analysis, brewed coffee using a French press, on average, emitted the second-highest amount of carbon dioxide.
