45,000 March in Brussels for Bold Climate Action

When record heatwaves took lives across Belgium this summer, 45,000 people decided enough was enough and took to the streets of Brussels.

The October 10 march brought together an inspiring coalition of voices. Students walked alongside trade unions, universities marched with human rights groups, and NGOs joined forces with youth movements in a peaceful show of unity.

Their message was clear: climate action cannot wait. The deadly summer heat made sleeping impossible for many, wildfires scorched the High Fens nature reserve, and excess deaths climbed to unprecedented levels across Belgium and Europe.

Aimen Horch, President of the Green Party in Flanders and Brussels, captured the moment perfectly. "People actually died from the heat," he told reporters at the march. "The urgency is not gone. The heatwaves are not gone."

The Climate Coalition organized the demonstration with five concrete demands: phasing out fossil fuel subsidies, creating more green spaces, ensuring a fair climate transition, supporting citizens and businesses moving away from fossil fuels, and strengthening international cooperation.

The timing matters. Next month, world leaders gather in Turkey for COP31, the annual UN climate summit. While expectations remain tempered after disappointing outcomes in recent years, the Brussels marchers sent a powerful message about public pressure for real change.

The Ripple Effect

This march represents something bigger than one day in one city. Despite political headwinds and competing priorities, 45,000 people choosing to spend their Sunday demanding climate action shows democracy in motion.

The diverse crowd proves climate concern spans generations and sectors. When universities and trade unions march together, when youth movements and human rights groups unite behind a common cause, it creates momentum politicians cannot ignore.

The EU remains the world's largest donor of public climate finance. This march reminds leaders that citizens expect them to maintain that leadership position, not water down commitments when challenges arise.

Brussels has now hosted multiple major climate demonstrations, each building on the last. The steady drumbeat of citizen engagement keeps pressure on policymakers even as other crises compete for attention.

The marchers know change takes time, but they're showing up anyway to make sure climate stays at the top of the agenda where it belongs.
