Cuba's Minister of Science, Technology and Environment, Elba Rosa Pérez, on Saturday called for greater and more ambitious leadership from developed countries in the fight against climate change.

Speaking on behalf of the Group of 77 and China at the resumption of the high-level segment for heads of state and government at COP28, the minister pointed out that the first global assessment of the Paris Agreement should emphasize the role of advanced nations.

He stressed that it is their responsibility given their historical share of cumulative greenhouse gas emissions, as well as the availability of resources and technologies to reduce their emissions.

He stressed that it is worrying that, while there is an urgent need to increase climate ambition, developed countries persist in their high levels of emissions, when they must comply with their obligation to increase climate action and support.

"The global balance sheet of the Paris Agreement must mean real pressure on developed countries to meet the commitments they have made on climate finance in support of developing countries," he said at another point.

He said that not even the goal of mobilizing $100 billion a year has been reached, which shows a profound lack of solidarity with billions of people living in nations highly vulnerable to climate change.

Pérez considered that the global balance should also improve the implementation of the convention in the contexts of sustainable development and efforts to eradicate poverty.

In addition, to achieve adequate, accessible and timely financing volumes and to provide the means of implementation needed by developing countries.

"The current challenge in many of our nations lies in the dual task of tackling climate change and pursuing sustainable development," he said, adding that poverty eradication is added to this.

None of this can be achieved in developing countries without support and assistance, he said.

"We must all contribute to slowing this phenomenon, but the principle of equity and common but differentiated responsibilities and effective capacities in the light of different national circumstances must not be ignored."

He highlighted the need for a framework to guide the implementation of the global adaptation target and explicitly indicate the provision of means to strengthen the adaptive capacity of developing countries.
