Environmental Expert Walid Oueslati Highlights Importance of COP 30
Environmental expert Walid Oueslati stated today, Tuesday, October 28, 2025, that the upcoming United Nations Conference on Climate Change (COP 30), scheduled to take place in Belém, Brazil, from November 6 to 21, holds particular symbolic significance as it marks the 10-year anniversary of the Paris Climate Agreement. He emphasized that Brazil has regained a central role on the international stage, particularly as an active member of the BRICS group and a influential voice in the fight against climate change.
Key Objectives of COP 30
During his intervention on the "Expresso" program, Oueslati explained that the summit will be a crucial step in establishing new policies aimed at limiting global temperature increase to 1.5 degrees Celsius by 2035. However, he warned that indicators for 2025 show that this threshold has already been exceeded, describing the current situation as "extremely worrying." He added that even if countries commit to reducing greenhouse gas emissions, estimates suggest that the temperature could rise by approximately 2.7 degrees Celsius by 2035, which he characterized as a "catastrophic scenario."
Insufficient Efforts
Oueslati noted that some countries have successfully reduced their emissions in the long term, but overall efforts remain insufficient. He indicated that the upcoming summit will focus on three main axes that represent the core of the challenge:
- Accelerating national policies to reduce emissions
- Launching projects with clear objectives in this area
- Providing necessary funding for their implementation
Financing and Implementation
Oueslati mentioned that COP 29 approved the allocation of $1.3 billion by 2035 to finance the efforts of developing countries in addressing climate change. He emphasized that the Belém summit will strive to define the mechanisms for disbursing these funds and the conditions for benefiting from them.
The Role of Developing Countries and Economic Institutions
Oueslati explained that heat emissions remain trapped in the atmosphere for decades, up to 70 years, exacerbating global warming. He also stressed that the participation of developing countries is necessary, but they must strongly engage in global efforts despite the economic cost. He noted that economic institutions play a central role in this process, as 70% of decarbonization efforts come from them. Oueslati emphasized that Corporate Social Responsibility (CSR) is no longer just a public relations facade, but has become an element that consolidates a company's credibility, increases its competitiveness, and attracts investment and financing.
Call to Action for Enterprises
Oueslati called on companies to reduce their heat emissions and master their value chains to ensure compliance with environmental standards, affirming that these steps are essential to reducing carbon footprint. He concluded by mentioning an event organized today by the United Nations in Tunisia, aiming to discuss ways to reduce heat emissions and the role of African companies in this global effort.
