Statement 1 is correct. Governments and industries often fear that stringent measures to reduce emissions, such as carbon taxes, cap-and-trade systems, or investments in costly clean technologies, could negatively impact economic competitiveness, lead to job losses, and slow down growth. Statement 2 is also correct. A major point of contention in international climate negotiations has been the principle of 'common but differentiated responsibilities', where developing nations argue that historical emissions are primarily from developed countries and that mandatory limits could hinder their necessary economic development and poverty reduction efforts. They often perceive such limits imposed by richer countries as attempts to restrict their growth.
