O porto de Itaqui, no Maranhão, prepara um plano de descarbonização, a ser lançado em outubro de 2024, para zerar as emissões de gases de efeito estufa até 2050, em meio a esforços para a transição energética.

O projeto é uma parceria entre a Empresa Maranhense de Administração Portuária (Emap) e o porto espanhol de Valência, que entregará três planos de ação para auxiliar Itaqui a definir futuras políticas e medidas. O porto brasileiro movimenta, principalmente, exportações de grãos e importações de derivados de petróleo, como diesel e gasolina.

Itaqui investiu R$1,8 milhão na iniciativa e recebeu o primeiro plano de ação,a respeito da metodologia do projeto, em setembro. Para os próximos passos, Valencia entregará um inventário da pegada de carbono do porto, em referência aos dados de 2022, que servirão como marco zero para o projeto. O plano final de descarbonização será divulgado em outubro do ano que vem.

Itaqui emite 700 t/ano de carbono, de acordo com pesquisas anteriores. "Acredito que as estimativas de Valencia serão um pouco maiores, pois os parâmetros internacionais podem ser diferentes", contou a gerente de Meio Ambiente do porto, Luane Lemos, à Argus.

Os três escopos de emissões de gases de efeito estufa, relativos a diferentes níveis de atividade, serão considerados no plano, que cobrirá de caminhões a navios e equipamentos portuários. "O documento vai nos orientar como poderemos substituir veículos poluentes, por exemplo", Lemos disse. "Pode ser com ferrovias, mudando o combustível ou trazendo as regiões consumidoras para mais perto."

Os caminhos para zerar as emissões também podem incluir hidrogênio, energia solar e eólicas offshore, ela acrescentou. A iniciativa para impulsionar fontes de energia renováveis no país é uma tendência em ascensão nos portos brasileiros. Suape, Santos e Pecém já anunciaram planos para produzir hidrogênio nos próximos anos.

O estado do Maranhão também está recebendo propostas de empresas internacionais sobre hidrogênio verde, contou Lemos à Argus. "Os navios estão evoluindo para usar combustíveis alternativos, e a amônia, o hidrogênio e gás têm sido ventilados como uma possível alternativa."

Mas os combustíveis fósseis não serão deixados de lado. "O mercado está mudando e estamos tentando acompanhar o mercado de combustíveis fósseis e outras demandas que estão chegando em decorrência de alterações globais", ela afirmou. Itaqui, inclusive, começará a exportar sebo bovino para ser utilizado como matéria-prima para renováveis no mês que vem.

O projeto de descarbonização é o primeiro em um porto brasileiro e teve 90pc de aderência de outras companhias que operam em Itaqui, como operadoras arrendatárias, agências que representam navios, profissionais de praticagem e transportadoras.

As discussões sobre mudanças climáticas não são novidade no porto maranhense, tendo começado em 2021. Após os primeiros inventários de emissões, , calculados no mesmo ano, autoridades enxergaram a necessidade de construir um plano de descarbonização, apontou Lemos. "Olhamos para Valencia, que possui metas de zerar as emissões até 2030 e muita experiência no setor."

Pemex's lean Zama spending undercuts goals

Mexico City, 21 November (Argus) — State-owned oil company Pemex's limited budget for developing one of Mexico's most-promising new oil fields is putting Mexico's crude production and refining goals at risk through 2030. First production from the Zama field will likely not start until at least 2028 instead of late next year, as forecast earlier, based on a timeline in a recent presentation from Pemex. Pemex continues to work on the basic engineering for the Zama field because of the lack of cash, staff of hydrocarbon regulator CNH said last week. The latest delay on Zama echoes criticism from when Pemex took over operating the field in 2022 that it did not have sufficient experience or funds to carry on with the project, said industry sources. "Unfortunately, the Pemex budget is always a shadowy mystery," said a person close to the project who asked not to be named. "There is no transparency or certainty regarding when they do and do not honor payment commitments." Zama is a shallow-water field unified in 2022 between Pemex area AE-152-Uchukil and the discovery made in 2017 by a consortium led by US oil company Talos Energy. Pemex holds 50.4pc of the Zama project while Talos and Slim's subsidiary Grupo Carso have 17.4pc, German company Wintershall Dea 17.4pc and British company Harbour Energy 12.4pc. The state-owned company expects to spend $370.8mn to develop Zama in 2025, 64pc less than the original $1.05bn budget proposed by Pemex for next year, according to data from CNH. The regulator cleared the change last week, but commissioners questioned the CNH staff about the new delays. Pemex's original development plan showed that the company forecast the first crude production by December 2025, with 2,000 b/d and about 4mn cf/d of gas. The original plan forecast Zama hitting peak production of 180,000 b/d in 2029, making it Mexico's second-largest crude producer, only under the Maloob field. President Claudia Sheinbaum and Pemex's new new chief executive Victor Rodriguez flagged the importance of shallow-water field Zama and ultra deep field Trion to support Pemex's oil production target of 1.8mn b/d in the upcoming six years in a presentation last week. Pemex's new plan is focused on feeding its own refining system rather than crude exports. The company expects to increase gasoline, diesel and jet fuel production by 343,000 b/d, according to the plan, but it did not give a timeline. Pemex produced 491,000 b/d of gasoline, diesel and jet fuel in the first nine months of 2024. Mexico's proposed 2025 federal budget also shows lower spending for Zama, at Ps3.1bn ($154mn) for 2025, even less than the figure approved by CNH on 14 November. Neither Pemex not Talos responded to requests for additional comment. "Zama is the story of the triumph of ideology over practicality," said a Pemex source who asked not to be named. The state-owned company is studying how to bring in new investors to the project once congress approves secondary laws to implement recent energy reforms, the source said. But uncertainty over the legal framework and the general deterioration of Mexico's business climate will make this more difficult, the Pemex source added. The involvement of Mexican billionaire Carlos Slim, who acquired 49.9pc of Talos Energy share in Zama last year, brought new hopes that work at Zama could finally accelerate. Instead, Slim's entrance slowed the project, as the new partner had to review the project, a former regulator who asked not to be named said. Talos Energy, the lead operator when the field was discovered over seven years ago, is now "frustrated" by the poor progress of the project. "We have Mexico, a great discovery in Zama, we're seven years into it, and still have not made a final investment decision on it," said Talos Energy interim chief executive Joseph Mills, in a conference call with investors last week. "So a lot of frustration there, as you can imagine."

Cost of government support for fossil fuels still high

Cost of government support for fossil fuels still high

London, 21 November (Argus) — The cost of government measures to support the consumption and production of fossil fuels dropped by almost third last year as energy prices declined from record highs in 2022, according to a new report published today by the OECD. But the level of fiscal support remained higher than the historical average despite government pledges to reduce carbon emissions. In an analysis of 82 economies, data from the OECD and the IEA found that government support for fossil fuels fell to an estimated $1.1 trillion in 2023 from $1.6 trillion a year earlier. Although energy prices were lower last year than in 2022, countries maintained various fiscal measures to both stimulate fossil fuel production and reduce the burden of high energy costs for consumers, the OECD said. The measures are in the form of direct payments by governments to individual recipients, tax concessions and price support. The latter includes "direct price regulation, pricing formulas, border controls or taxes, and domestic purchase or supply mandates", the OECD said. These government interventions come at a large financial cost and increase carbon emissions, undermining the net-zero transition, the report said. Of the estimated $1.1 trillion of support, direct transfers and tax concessions accounted for $514.1bn, up from $503.7bn in 2022. Transfers amounted to $269.8bn, making them more costly than tax concessions of $244.3bn. Some 90pc of the transfers were to support consumption by households and companies, the rest was to support producers. The residential sector benefited from a 22pc increase from a year earlier, and support to manufacturers and industry increased by 14pc. But the majority of fuel consumption measures are untargeted, and support largely does not land where it is needed, the OECD said. The "under-pricing" of fossil fuels amounted to $616.4bn last year, around half of the 2022 level, the report said. "Benchmark prices (based on energy supply costs) eased, particularly for natural gas, thereby decreasing the difference between the subsidised end-user prices and the benchmark prices," it said. In terms of individual fossil fuels, the fiscal cost of support for coal fell the most, to $27.7bn in 2023 from $43.5bn a year earlier. The cost of support for natural gas has grown steadily in recent years, amounting to $343bn last year compared with $144bn in 2018. The upward trend is explained by its characterisation as a transition fuel and the disruption of Russian pipeline supplies to Europe, the report said.

Cop: Talks in Baku torn between mitigation and finance

Edinburgh, 21 November (Argus) — Developing and developed nations remain at loggerheads on what progress on climate finance and mitigation — actions to cut greenhouse gas emissions — should look like at the UN Cop 29 climate summit. But Cop 30 host Brazil has reminded parties that they need to stick to the brief, which is finance for developing countries. Concluding a plenary where parties, developed and developing, listed grievances, environment minister Marina Silva recognised "the excellent progress achieved" on mitigation at Cop 28. She listed paragraphs of the Cop 28 deal, including the energy package and its historic call to transition away from fossil fuels in energy systems. "We are on the right track," she said, talking about mitigation, but "our greatest obligation at this moment is to make progress with regard to financing". "This is the core of financing that will pave our collective path in ambition and implementation at Cop 30," Silva said, adding that $1.3 trillion for developing countries should be "the guiding star of this Cop". Parties are negotiating a new collective quantified goal (NCQG) — a new climate finance target — building on the $100bn/yr that developed countries agreed to deliver to developing countries over 2020-25. But developed countries insist that a precise number for a goal can only be produced if there is progress on mitigation and financing structure for the NCQG. "Otherwise you have a shopping basket but you don't know what's in there," EU energy commissioner Wopke Hoekstra said. Some developing nations said they need the "headline number first". Some developing countries, including Latin American and African nations as well as island states, have also complained about the lack of mitigation ambition. Cop is facing one of the "weakest mitigation texts we have ever seen," Panama said. But they also indicated that financial support was missing to implement action. Developed countries at Cop 29 seek the implementation of the energy pledges made last year. "What we had on our agenda was not just to restate the [Cop 28] consensus but actually to enhance and to operationalise that," but the text goes in the opposite direction, Hoekstra said, talking about the latest draft on finance. Whether hints that Brazil has mitigation in focus for next year's summit will be enough to assuage concerns from developed countries at Cop 29 on fossil fuel ambitions remains to be seen. The communique of the G20, which the country hosted, does not explicitly mention the goal to transition away from fossil fuels either. The developed countries' mitigation stance grew firmer after talks on a work programme dedicated to mitigation, the obvious channel for fossil fuel language, was rescued from the brink of collapse last week. Discussions have stalled, but another text — the UAE dialogue which is meant to track progress on the outcomes of Cop 28 — still has options referring to fossil fuels. But in these negotiations too, divisions remain. "The UAE dialogue contains some positive optional language on deep, rapid and sustained emissions reductions and the [Cop 28] energy package, E3G said. But Saudi Arabia has made clear that this was unacceptable, while India, which worked to water down a coal deal at Cop 26, is pushing back on the 1.5°C temperature limit of the Paris Agreement. Negotiators are starting to run out of time. Draft after draft, the divide fails to be breached with no agreement on an amount for the finance deal. "We cannot talk about a lower or higher number because there is no number," noted Colombia's environment minister Susana Muhamad. The next iteration should have numbers based on the Cop 29 presidency's "view of possible landing zones". The fact that the draft text on finance has no bridging proposal is a concern, non-profit WRI director of international climate action David Waskow said. Finance was always meant to be the centrepiece of Cop 29. Parties have not formally discussed the goal in more than 15 years, and have been trying to prepare for a new deal through technical meetings for the past two years. But the discussion needs to end in Baku. By Caroline Varin Send comments and request more information at feedback@argusmedia.com Copyright © 2024. Argus Media group . All rights reserved.

Cop: EU, four countries commit to 1.5°C climate plans

Baku, 21 November (Argus) — The EU, Canada, Mexico, Norway and Switzerland have committed to submit new national climate plans setting out "steep emission cuts", that are consistent with the global 1.5°C temperature increase limit sought by the Paris Agreement. The EU and four countries made the pledge at the UN Cop 29 climate summit in Baku, Azerbaijan today, and called on other nations to follow suit — particularly major economies. Countries are due to submit new climate plans — known as nationally determined contributions (NDCs) — covering 2035 goals to the UN climate body the UNFCCC by early next year. The EU, Canada, Mexico, Norway and Switzerland have not yet submitted their plans, but they will be aligned with a 1.5°C pathway, EU climate commissioner Wopke Hoekstra said today. The Paris climate agreement seeks to limit the global rise in temperature to "well below" 2°C and preferably to 1.5°C. Canada's NDC is being considered by the country's cabinet and will be submitted by the 10 February deadline, Canadian ambassador for climate change Catherine Stewart said today. Switzerland's new NDC will also be submitted by the deadline, the country's representative confirmed. Pamana's special representative for climate change Juan Carlos Monterrey Gomez also joined the press conference today. Panama, which is designated as carbon negative, submitted an updated NDC in June. It is planning to submit a nature pledge, Monterrey Gomez said. "It is time to streamline processes to get to real action", he added. The UK also backed the pledge. The UK announced an ambitious emissions reduction target last week. The UAE — which hosted Cop 28 last year — released a new NDC just ahead of Cop 29, while Brazil, host of next year's Cop 30, released its new NDC on 13 November during the summit. Thailand yesterday at Cop 29 communicated a new emissions reduction target . Indonesia last week said that it intends to submit its updated NDC ahead of the February deadline, with a plan placing a ceiling on emissions and covering all greenhouse gases as well as including the oil and gas sector. Colombia also indicated that its new climate plan will seek to address fossil fuels, but it will submit its NDC by June next year .

Cop: EU says finance draft text not acceptable

Baku, 21 November (Argus) — The latest draft of the text on climate financing presented at the UN Cop 29 climate summit is not ambitious enough on mitigation — reducing emissions — and "clearly unacceptable," EU energy commissioner Wopke Hoekstra said today. Parties must agree at Cop 29, in Baku, Azerbaijan, on a new collective quantified goal (NCQG) — a new climate finance target — building on the $100bn/yr that developed countries agreed to deliver to developing countries over 2020-25. The text is the main outcome for the summit. "What we had on our agenda was not just to restate the [Cop 28] consensus but actually to enhance that and to operationalise that," but the text goes in the opposite direction, Hoekstra said. Parties to last year's Cop 28 summit in Dubai made an historic pledge to "transition away" from all fossil fuels. The EU has warned against any backsliding on this pledge . "We cannot accept the view that the previous Cop did not happen," Hoekstra said. A draft text on the mitigation work programme — a process that focuses on emissions reduction — was released by the Cop 29 presidency in the early hours of this morning. It does not mention phasing out or reducing fossil fuels in energy systems, or reference the agreement reached on the latter point at Cop 28 last year. Hoekstra indicated today's text does not provide enough clarity to allow the EU to put a concrete number on the amount of climate finance that should be available. The bloc has insisted the final number for climate financing can come only when other elements, including the structure and contributor base, are settled. But recipient country groups such as the G77 and Like-Minded Developing Countries (LMDC) groups have expressed impatience at the lack of a concrete number. Minor bright spots in the numerous draft texts released overnight include those on Article 6, which governs international carbon credits, Hoekstra said. But the commissioner is "sure there is not a single ambitious country who thinks this is nearly good enough."
