In a bold demonstration of environmental commitment, hundreds of climate activists are cycling thousands of kilometers to attend the United Nations COP30 climate summit in Belém, Brazil, this November. The journey, which began in Azerbaijan—the host of last year’s COP29 summit—has already spanned nearly 8,000 kilometers across Eurasia over 20 weeks. A second group of 200 cyclists covered an additional 1,800 kilometers across northern Europe, while others traversed parts of eastern and southern Africa. The riders, united under the banner of the COP30 Bike Ride, are now sailing from Portugal to Brazil aboard the schooner Avontuur, avoiding air travel to minimize their carbon footprint. The initiative, organized by Dutch activist Jolein Schorel, aims to highlight cycling as a sustainable, healthy, and cost-effective alternative to fossil-fuel-dependent transportation. Schorel emphasized that the journey is not just symbolic but also a practical call for cities to invest in cycling infrastructure. Along the way, the cyclists have engaged with local communities, sharing their mission and inspiring grassroots support. In Zambia, for instance, a young boy offered his only coin to support the riders, a gesture that deeply moved Schorel. The activists plan to present their demands for stronger climate action, particularly in protecting the Amazon rainforest and phasing out fossil fuels, when they arrive in Belém. Their journey underscores the power of collective action and the feasibility of sustainable alternatives in addressing the climate crisis.
