The upcoming Bonn Climate Change Conference, slated for June 8 to 18, 2026, faces significant challenges as several of the world’s most impoverished and climate-vulnerable nations struggle to secure visas for their delegates. This predicament jeopardises their ability to engage in critical discussions on climate policy, potentially undermining the representation of those most affected by global warming.

Visa Challenges for Underrepresented Nations

Delegates from countries such as Sudan, Yemen, Sierra Leone, Senegal, and The Gambia have reported considerable difficulties in obtaining the necessary visas to attend the conference. These nations, already grappling with the adverse effects of climate change, are now forced to send smaller delegations, diminishing their influence in negotiations that are pivotal for their futures.

Dalal Ebrahim, who heads the climate adaptation department for Sudan, expressed profound disappointment regarding the visa hurdles faced by her country’s representatives. “The majority of our delegation, including our lead negotiator, have encountered visa refusals, and others are still struggling to secure appointments with German embassies,” she lamented.

Yemen’s Marwah Aref Ahmed Saleh echoed similar frustrations, revealing that despite being sponsored twice for a German visa by the International Institute for Environment and Development, she was unable to gain approval to travel. “Even reaching a country where I can apply for a visa is a considerable challenge,” she stated, highlighting the compounded difficulties of travel from Yemen.

The Significance of the Bonn Climate Conference

The Bonn Climate Change Conference serves as an essential platform for discussing technical climate policies. It plays a crucial role in shaping the agenda for the upcoming COP31 climate conference in November, taking place in Anatolya, Turkey. With nearly 200 countries expected to convene, the outcomes of these discussions will have far-reaching implications for global climate action.

However, representatives from the affected nations emphasise that their diminished presence at Bonn will severely limit their capacity to engage in negotiations. “Normally, a larger delegation would allow us to cover multiple negotiation tracks simultaneously,” Marwah explained. The reduced representation means that vital issues facing their countries may not be adequately addressed.

Impacts of Exclusion on Climate Diplomacy

The absence of delegates from the most vulnerable nations raises concerns about the integrity of climate diplomacy. “Visa barriers should not serve as a hidden means of silencing voices that are pivotal to the climate crisis,” Dalal asserted. She stressed that discussions on climate adaptation and finance must include the realities faced by nations like Sudan, which are on the frontlines of climate impacts.

In a response to these concerns, a spokesperson for the German Federal Foreign Office acknowledged the importance of delegate participation, particularly from countries most affected by climate change. However, they cited strict adherence to Schengen laws governing visa applications, stating that decisions are based on available evidence regarding the applicants’ intent to return to their home countries.

Binyam Gebreyes, a climate diplomacy expert from IIED, underscored the significance of inclusive representation at UNFCCC meetings. “Physically excluding negotiators from the Least Developed Countries sends a message that their contributions do not matter to the global community,” he remarked.

Why it Matters

The inability of the most vulnerable nations to participate in the Bonn Climate Change Conference underscores a broader issue of inequity in climate discussions. These nations, already facing severe consequences from climate change, must be given a platform to voice their experiences and needs. Their exclusion not only undermines the credibility of global climate negotiations but also threatens to exacerbate the very inequalities that climate agreements aim to address. As the world grapples with the urgent need for climate action, ensuring that all nations can contribute to the dialogue is not just a matter of justice but a prerequisite for effective solutions.
