What is Warm Sweater Day?

Warm Sweater Day, or Warmetruiendag, is an annual event in the Netherlands focused on promoting energy conservation and raising awareness about climate change. Celebrated in February, the day encourages participants to lower their heating by at least one degree Celsius and wear warm sweaters to stay comfortable. This simple gesture aims to reduce energy consumption and CO₂ emissions, demonstrating the power of collective, small-scale actions in tackling global environmental challenges.

History and Origin

Warm Sweater Day was first organized in 2007 by Klimaatverbond Nederland, a coalition of public organizations dedicated to sustainability. The event is tied to the anniversary of the Kyoto Protocol, signed on February 16, 1997, which was the first global agreement on reducing greenhouse gas emissions. By commemorating this milestone, Warm Sweater Day highlights the importance of individual and communal responsibility in combating climate change.

The initiative quickly gained popularity across the Netherlands, with schools, businesses, and households participating in thermostat-lowering efforts. The day has become a symbol of the Dutch commitment to energy conservation and sustainability.
