O caminho para a sustentabilidade: O desafio europeu das emissões no sector dos transportes

Criado: 08/08/2024

Atualizado: 08/08/2024

Um relatório de 2024 da Clean Technica revelou que mais de 25% das emissões do tráfego rodoviário provêm do sector dos transportes na Europa - sendo os veículos pesados responsáveis por 85% das emissões (os autocarros e camionetas representam o restante).

Ao ritmo atual, o sector dos transportes representará, por si só, quase metade das emissões de gases com efeito de estufa da Europa em 2030 - as emissões dos transportes na Europa continuaram a aumentar em mais de um quarto desde 1990. As emissões em toda a economia diminuíram - contudo, desde o pico atingido em 2007, o sector dos transportes tem vindo a descarbonizar-se mais três vezes mais lentamenter do que o resto da economia.

Qual é a causa do aumento das emissões de CO2 no sector dos transportes?

Desde a proliferação do comércio eletrónico e dos serviços de entrega ao domicílio, a procura de mais camiões na estrada aumentou significativamente. Consequentemente, o aumento da procura resultou num aumento das emissões de CO2 no sector dos transportes.

Um relatório da [Clean Technica] (https://cleantechnica.com/2024/05/13/eu-wisely-stiffens-road-freight-passenger-emissions-guidance/) sobre a tonelagem do transporte doméstico de mercadorias em diferentes modos (rodoviário, ferroviário e marítimo) revelou que o transporte rodoviário de mercadorias é mais dominante na Europa do que o ferroviário e marítimo, em comparação com outras regiões (EUA e Índia). Embora a China esteja mais dependente do transporte rodoviário de mercadorias, o relatório revelou que o país operava com cerca de 600 000 camiões eléctricos para entregar mercadorias.

Que planos estão a ser implementados na Europa para reduzir as emissões de CO2?

O Parlamento Europeu adoptou a [Lei Europeia do Clima] (https://climate.ec.europa.eu/eu-action/european-climate-law_en#:~:text=The%20European%20Climate%20Law%20writes,2030%2C%20compared%20to%201990%20levels.) para fazer face ao aumento das emissões de CO2. Como parte desta lei, o objetivo da UE de reduzir as emissões líquidas de gases com efeito de estufa até 2030 foi aumentado para, pelo menos, 55% - tornando a neutralidade climática até 2050 juridicamente vinculativa.

Em maio de 2024, os países da UE aprovaram uma lei para reduzir as emissões de CO2 dos camiões. A nova lei exigirá que os novos veículos pesados vendidos na UE a partir de 2040 sejam isentos de emissões, impondo simultaneamente uma redução de 90% das emissões de CO2 dos novos veículos pesados de mercadorias até ao mesmo ano. Os fabricantes devem vender uma grande quantidade de veículos pesados totalmente isentos de CO2 - por exemplo, veículos eléctricos e a hidrogénio - para compensar as restantes vendas de veículos que emitem CO

Que acções podem os gestores de frotas tomar para reduzir as emissões de CO2?

Os gestores de frotas podem adotar medidas para reduzir as suas emissões de CO2:

  • A travagem brusca, a aceleração rápida e o ralenti podem aumentar o consumo de combustível e as emissões de gases com efeito de estufa - Embora a monitorização do comportamento do condutor possa ser um desafio, a tecnologia de IA pode fornecer feedback contínuo aos condutores e gestores de frotas. Saiba mais sobre como a IA pode ter um impacto positivo na sustentabilidade no sector dos transportes.

  • As frotas com veículos mais antigos podem mudar para veículos pesados de mercadorias movidos a óleo vegetal tratado com hidrogénio (HVO), hidrogénio ou eletricidade para reduzir significativamente as emissões. No entanto, os gestores de frotas devem ter em conta a distância que os veículos alimentados por combustíveis alternativos podem percorrer e as implicações em termos de custos.

  • A [Conta SNAP] (https://snapacc.com/) permite aos gestores de frotas reduzir a quilometragem dos desvios - com mais de 600 parceiros de serviços disponíveis para os clientes da Conta SNAP, os gestores de frotas podem planear paragens nocturnas para os seus condutores durante o percurso.

Existem infra-estruturas para carregar veículos pesados de mercadorias eléctricos?

De acordo com um [estudo da PwC] (https://www.strategyand.pwc.com/de/en/industries/transport/the-dawn-of-electrified-trucking.html), até 2030, um terço de todos os camiões na Europa serão eléctricos. Uma vez que as empresas de frotas estão a tomar medidas no sentido da eletrificação, as paragens de camiões em toda a Europa têm de ser capazes de satisfazer a procura de estações de carregamento elétrico.

A disponibilização da infraestrutura terá um custo para muitas paragens de camiões e estações de serviço. No entanto, aqueles que já dispõem de carregadores para veículos eléctricos estão bem posicionados para tirar partido das futuras vagas de camiões eléctricos. Até 2030, as estações de carregamento públicas na Europa aumentarão para mais de 3.600 - A UE apresentou uma lei ambiciosa para o carregamento com o Regulamento de Infra-estruturas para Combustíveis Alternativos (AFIR). O AFIR planeia equipar a rede rodoviária principal com parques de carregamento a cada 60 km - fornecendo energia de carregamento e capacidade de hidrogénio suficientes para que 9% das frotas de camiões e autocarros tenham emissões zero até 2030.

Qual é o país europeu com mais emissões de CO2?

Em 2021, a Alemanha, a França e a Itália foram responsáveis pelas maiores emissões globais de gases com efeito de estufa (GEE) - variando entre [375 000 e 740 000 kton de CO2] (https://ccpi.org/which-european-countries-are-the-worst-climate-polluters-and-why/). No entanto, os países com maiores populações produzem mais emissões de GEE - por conseguinte, a visualização das emissões globais de gases com efeito de estufa fornece uma imagem distorcida.

Uma visão imparcial das emissões oferece uma perspetiva diferente: o Luxemburgo, a Irlanda e a República Checa produziram as emissões per capita mais elevadas da UE em 2021.

Qual é a forma mais ecológica de transportar mercadorias?

O transporte de mercadorias por caminho de ferro é um dos modos de transporte mais limpos, mas também oferece outros benefícios:

  • Reduz o congestionamento rodoviário, o que contribui para melhorar a qualidade do ar.

  • O caminho de ferro oferece uma forma mais rápida de transportar mercadorias e elimina os obstáculos ao tráfego pesado.

Os camiões de combustível alternativo são outra forma amiga do ambiente de transportar mercadorias. O óleo vegetal tratado com hidrogénio (HVO) pode reduzir imediatamente até 90% das emissões de gases com efeito de estufa em comparação com o gasóleo normal ao longo do ciclo de vida do produto. A Certas Energy HVO está por detrás da mudança para uma alternativa mais limpa - ajudando as empresas a atingir os seus objectivos de sustentabilidade e a dar passos significativos em direção ao seu futuro líquido zero.

ESCASSEZ DE CONDUTORES NO REINO UNIDO: OS NÚMEROS ESTÃO A MELHORAR?

Susie Jones

Anyone working in the haulage industry is no stranger to the term; 'Driver Shortage' a phrase all too common since COVID-19 and Brexit disrupted the sector. The UK was hit hard during this time, with many EU drivers leaving the country a big loss as European drivers made up a significant portion of its truck driving workforce.Six months after our on this topical issue, we examine where the sector is now. Figures published by showed an increase of almost 55,000 HGV Drivers employed over the last year a 21% rise. Several initiatives have come to fruition to try to ease the driver shortage in the UK. • The government has implemented 33 initiatives aimed at easing the shortage. These include but are not limited to, relaxing the rules for late-night supermarket deliveries, driver training boot camps, and increasing the number of available driving tests. • Truck drivers have been across the UK, with 55% wanting improved facilities. The has provided £16 million to truck stops to improve facilities. Influencers have played a significant role in changing public perceptions regarding the industry. Drivers like and use their platforms to highlight the highs and lows of working in the sector.Logistics UK also reported that the number of drivers under the age of 35 rose by 31,630 between Q3 2023 and Q3 2024. Despite this, the industry still relies on older drivers with more than 53% across the sector aged 50 and over. A report from the RHA, titled , suggests initiatives to attract younger people into the industry by:• Fully implementing the 8 Gatsby Benchmarks to provide an effective career guidance system to all school-age students to boost awareness. • Increasing collaboration with schools and colleges.• Developing a formal school or college-based qualification such as a T-Level.• Incorporating logistics modules in the current curriculum.• Leveraging government-supported initiatives incorporated within the Make Work Pay programme, showcasing logistics as an accessible and rewarding career path.Although work has already begun to tackle the driver shortage, more work needs to be done to avoid a repeat of 2021:• More government funding must become available for truck stops to improve facilities. • Providing ongoing support for aspiring drivers, including boot camps to reduce training costs.• Offering greater flexibility within the new Growth and Skills Levy.• Collaborating with schools and colleges at a local level to promote careers in the industry. HGV drivers are leaving the industry for a multitude of reasons:• Ageing workforce: With many truck drivers over 50, the industry has seen an influx of drivers retiring. • Working hours: Trucking is a lonely profession, with drivers working long, irregular, and antisocial hours behind the wheel. • Working conditions: There have been significant concerns regarding the state of facilities, long hours, and unpredictable schedules.

DIA DOS CONDUTORES DE VEÍCULOS PESADOS DE MERCADORIAS 2025: DAR VOZ AOS CAMIONISTAS

Miranda Blake

On 22nd January 2025, it’s HGV Drivers Day. Established by NN1 Personnel (recruiters and suppliers of truckers in the logistics industry), the day aims to celebrate drivers and all they do for the economy and society. Without truckers, who often experience various difficulties in the role (including being away from their families and home, long working hours, and travelling in extreme weathers), we would be without our necessary products and convenience. They truly have been heroes over the last few years as well as prior to that – the pandemic was only one example of this. How you mark the day is up to you. , for example by providing drivers with a hot drink or chatting with them. Here at SNAP, we’re always keen to give truckers a voice. And so, for this HGV Drivers Day, that’s exactly what we’re doing. Following a recent post on our asking about the and how to ensure young people have the enthusiasm to join the industry, we’re highlighting some of the commentary from truckers that show their real-life experiences – from the challenges they face to what they love about their job. A key talking point for drivers is how the role impacts their personal lives, such as not being there for important moments in life, having to sleep in their cab, and the money not being worth the sacrifices they make. Statistics back up the feedback. For example, it’s been found ) – compared to 37.5 hours for all employees, this is a substantial 28% higher. And so, it’s not surprising . Nor is it shocking that such a significant number have left the sector, including . For some who commented, they’ve moved on from the industry and into other roles that make them happier. But for others, they reflected on the good memories of riding in lorries with their dads as children, along with the value of it and how this experience led them to join the sector themselves after finishing their education. On a similar note, many disagreed with trucking not being the ideal job – whether it was for the money or just their love of driving a lorry. All these comments make it clear that while truckers certainly face challenges, there’s still a lot to love and for some it’s a career they’re happy to do for life – so it makes sense that around . We think it’s crucial everyone acknowledges all truckers do for us. Unfortunately, some drivers pointed out that they experience a significant lack of respect. This shouldn’t be the case – they should be recognised for what they do to give us all the bare necessities in life. As one trucker put it: So, this HGV Drivers Day – and every other day, in fact – we ask everyone to acknowledge those out on the road for us. Truckers deserve praise, respect, and so much more.

O CAMINHO A SEGUIR ATÉ 2025: TENDÊNCIAS DA INDÚSTRIA DE CAMIÕES A ESPERAR

Miranda Blake

From general driver unhappiness to the recent driver CPC changes to delays to the , 2024 has been a whirlwind for the logistics industry. And there’s plenty on the horizon for 2025 – here we explore the trends expected to shape the sector. It's anticipated that automation will play a key role in the year ahead. There will be developments in autonomous vehicle technology, transportation management systems, and electronic logging devices – resulting in more adoption and considerable changes within the industry. Plus, an increase in for , predictive maintenance, and fleet management is on the cards. This will trigger better results such as improved operational efficiency and reduced costs. The Internet of Things (IoT) and machine learning will be particularly valuable, being utilised to foresee equipment malfunctions, which will curtail downtime. On a similar note, telematics will share valuable live data related to vehicle performance, driver behaviour, and cargo status – leading to better safety and compliance. Attracting more female truckers is a way to deal with the . Employers could provide a wider range of roles, introduce training programmes and policies that would benefit women, and make the working environment more inclusive. With the latter, ideas include mentoring or working patterns that better suit the lives of truckers (like day shifts and covering circular routes to support those with family commitments). However, discussion on the revealed both male and female drivers need change. While some pointed out that certain things could be better for women (for instance, one remarked that 90% of depot facilities don’t have sanitary bins), there were many comments about the overall employee package and truck stop amenities: And so, companies should look at how to entice and retain their entire workforce. They may offer better compensation, working conditions, and opportunities for development. Likewise, they can implement training to ensure people have all the right capabilities – for now and the future. Another core focus will be – especially due to increasingly stricter environmental laws, the move towards net zero, and skyrocketing fuel prices. Alternate fuel vehicles didn’t meet expectations in 2024, so it’s anticipated that while innovation in this area will still happen, there will be more of a shift towards focusing on how fleets can boost operational efficiency (for example, by using technology, data, and AI to reduce wasted time). Companies will also look to build greener supply chains by working with more eco-friendly suppliers and carriers. Similarly, the move to electric trucks is on the rise – there will be more of a rollout of EV charge points in truck parks this year. However, fleet companies face barriers such as substantial upfront costs and an insufficient amount of charging infrastructure. Lastly, there’s a predicted surge in air and ocean cargo, which will have a knock-on effect on the trucking industry. This is only heightened by global supply chains becoming more and more interconnected. As a result, there will be a rise in long-distance freight – making it even more important that drivers have adequate breaks at safe truck stops. And this is where can help. Our has over , including in Austria, Bulgaria, Czechia, Greece, Hungary, Italy, and Romania. We help make fleet management simple and ensure both operators and truckers can adhere to in 2025 and beyond. To learn more, get in touch with our team on +44 (0)1603 777242.
