BELEM, Brazil (CMC) – The 30th Conference of the Parties of the UN Framework Convention on Climate Change (UNFCCC) began here on Monday, with a clear message that the era of half-measures is over and that climate change is real, devastating communities and driving up costs, but solutions are within reach.

UN Climate Change Executive Secretary, Simon Stiell, said that commitments and agreements made by successive COPs were beginning to show impact, with the global emissions curve now starting to bend downward.

The former senior Grenada government minister acknowledged that much work remains but highlighted that Belém “home to the mouth of the mighty Amazon River” can serve as inspiration.

“The Amazon is not a single river, but a vast system sustained by more than a thousand tributaries. In the same way, implementation of COP outcomes must be driven by multiple streams of international cooperation.”

Stiell urged delegates to focus on turning ambition into action, saying “your  job here is not to fight one another, your job here is to fight this climate crisis, together. This is the growth story of the 21st century – the economic transformation of our age.”

Stiell warned that “no national plan can solve this problem on its own,” stressing that no country can afford the economic shock of climate disasters that slash gross domestic product (GDP) by double digits.

“It makes neither economic nor political sense to stand idle while catastrophic droughts destroy crops and drive food prices sky-high,”  he said, calling it “unforgivable” that extreme weather continues to claim millions of lives when proven solutions already exist.

Among the key priorities for COP30, highlighted by Stiell are a just and orderly transition away from fossil fuels, tripling renewable energy capacity and doubling energy efficiency, mobilizing US$1.3 trillion annually for climate action in developing countries as well as approving a global framework of adaptation indicators and advancing the Work Programme on Just Transition and the Technology Implementation Programme.

Brazil’s President Luiz Inácio Lula da Silva, in his address said the conference provides the  moment to match opportunity with urgency, calling for a decisive defeat of climate denial and faster action to keep the 1.5°C goal alive.

A preliminary assessment by the UNFCCC, which convenes the yearly COPs, suggests these pledges could cut emissions by 12 per cent by 2035. It’s progress, but not yet enough to guarantee the 1.5°C goal. The challenge now is turning promises into action at a pace that matches the scale of the crisis.

President Lula warned that “climate change is not a threat to the future – it is a tragedy of the present.”

Citing Hurricane Melissa in the Caribbean and a tornado in Paraná, the president said described COP 30 as “the COP of truth,” warning that denial and delay are no longer options. “We are moving in the right direction, but at the wrong speed. Crossing 1.5°C is a risk we cannot take.”

He called for an end to climate denialism, underscoring that “in the age of disinformation, obscurantists reject not only scientific evidence but also the progress of multilateralism.

“They control algorithms, sow hatred, spread fear, and attack institutions, science, and universities. It is time to impose a new defeat on denialists. Without the Paris Agreement,  the world would be heading toward catastrophic warming of nearly 5°C by the end of the century.”

President Lula pressed world leaders to adopt ambitious climate pledges and keep adaptation at the heart of national strategies. He called for “a roadmap for humanity to overcome, in a just and planned way, its dependence on fossil fuels, reverse deforestation, and mobilize the resources needed to do so.”

To back that vision, he announced a new fund to support energy transitions in developing countries, financed by revenues from oil exploration.

The Leaders’ Summit, held on November 6 and 7, has already mobilized US$5.5 billion for the Tropical Forests Forever Facility – a fund designed to reward nations for protecting rainforests.

Other collective commitments include recognizing Indigenous land rights, quadrupling sustainable fuel production, and linking climate action to the fight against hunger, poverty, and environmental racism.

Bringing COP30 to the heart of the Amazon was, in Lula’s words, “a difficult but necessary task,” giving the world a chance to witness the realities of the planet’s most biodiverse biome—home to more than 50 million people and 400 Indigenous groups.

“May the serenity of the forest inspire the clarity of thought needed to see what must be done,” he said.

COP30 President, André Corrêa do Lago, presiding over the official opening of the summit, urged delegates to make this the “COP of implementation, adaptation, and economic integration of climate policy – and above all, the COP that listens to and believes in science”.

He recognized the crucial role of Indigenous Peoples as guardians of the Amazon, the region now at the centre of the world’s attention.

Meanwhile, the Barbados-based Caribbean Development Bank (CDB) said against the backdrop of a devastating hurricane season that once again underscored the region’s extreme vulnerability, it is taking will take the Caribbean’s climate agenda to the global stage.

The region’s premier financial institution ill lead and participate in a series of events, high level discussions and bilateral engagements aimed at securing greater access to concessional climate finance and strengthening partnerships for sustainable development.

“The Caribbean’s climate reality has never been clearer or more urgent,” CDB President Daniel Best said, adding that this intensified engagement reflects both the urgency and opportunity of the moment

“The recent passage of Hurricane Melissa has underscored what we’ve been warning for years: without predictable, concessional finance, small island states cannot keep pace with escalating climate impacts.

“COP30 is one of the most consequential arenas for advancing our case for climate justice and fair financing, and the Caribbean Development Bank will ensure our region’s voice is heard.”

At COP30, the CDB said that it strategically engage governments, international partners, and private investors to deepen partnerships and advocate for increased concessional financing and innovative mechanisms to mobilise resources for the region.

On Monday, November 17, CDB will co-host three side events that reflect key priorities for climate action and resilience in the Caribbean.

The first session, “Leveraging Private Sector Financing for Transport and Energy Sector Transformation in the Caribbean,” will explore strategies to unlock private capital through blended finance models, risk-sharing instruments, and innovative partnerships to accelerate investment in renewable energy and sustainable transport systems.

A discussion on “Agriculture and Food Security in the Caribbean: Scaling Innovative Solutions for Climate-Resilient Agriculture” will spotlight climate-smart agricultural practices and investment opportunities that can strengthen food security and reduce the region’s dependence on imports.

CDB is also collaborating with the Development Bank of Latin America and the Caribbean (CAF), the Central American Bank for Economic Integration (CABEI) and the CREWS Secretariat to turn attention to disaster preparedness with a panel on “Climate Information and Early Warning Systems for Latin America and the Caribbean”.

That discussion will explore initiatives by the three institutions to finance and implement early warning systems for the region.

“CDB’s agenda at COP30 underscores our approach to climate action, which is practical, innovative, and built on partnerships. The Caribbean is helping itself by developing our own solutions to protect lives, preserve livelihoods and transform our energy, transport and agriculture systems to secure our future, but we need the global community to stand with us,”  Best  said.

CDB said that it is targeting 30-35 per cent of its resources to climate finance demonstrating its commitment to helping Borrowing Member Countries (BMC) adapt to the accelerating climate crisis.

“The Bank is also better positioned to deliver transformative regional interventions through a recent increase in its GCF financing threshold to US$250 million and its new Climate Change Project Preparation Fund,  both of which will help countries design and finance concrete, high-impact projects faster and more effectively,”  it added.
