Identification of economic incentives for the electrification of river and maritime modes: proposal for the Colombian Case

The transportation sector's significant contribution to greenhouse gas (GHG) emissions, primarily through fossil fuel consumption by motorized vehicles, remains a critical concern. In this industry, maritime transportation independently contributes to 2.89% of total global greenhouse gas emissions, displaying a persistent upward trend even in the face of enhanced efficiency measures implemented in port facilities and vessel operations. In response to this urgent concern, nations and international organizations have been formulating approaches aimed at mitigating greenhouse gas emissions in this transportation sector, encompassing the implementation of economic incentives. This article presents the findings of an exploratory-descriptive research endeavor, which aims to identify incentive policies implemented across various countries to expedite the adoption of electromobility in maritime and river transportation, thereby reducing GHG emissions from vessels. Data was gathered from authorized government websites, various organizations, maritime and river transport companies, and port authorities in each respective nation. Furthermore, this study classifies the incentives according to their methodologies and conducts a comparative analysis with the existing landscape in Colombia regarding the adoption of economic incentives for electrifying river transportation within the country. Through this analysis, some insights and recommendations can be derived to promote sustainable and environmentally-friendly practices in Colombia's river and maritime transportation sectors.

According to a comprehensive report by the International Maritime Organization (IMO, 2020), the transportation of goods and passengers emerges as a prominent source of greenhouse gas emissions worldwide. This crucial sector significantly contributes to approximately 2.89% of the total annual emissions. To address this environmental challenge, sustainable transportation solutions have become a focal point in the quest for mitigating climate change impacts. The Intergovernmental Panel on Climate Change (IPCC) emphasizes the importance of adopting sustainable transport practices to reduce carbon emissions and achieve global climate goals (IPCC, 2021). It is evident that the reduction of emissions in the transportation sector is a critical element in the pursuit of a sustainable and greener future.
Recognizing the urgent need to address these detrimental environmental impacts, multiple initiatives and research sources emphasize the imperative of emission reduction in the transport sector. For instance, the Net Zero Emission by 2050 Scenario proposed by the International Energy Agency underscores the urgency of achieving a 20% reduction in the transport sector's emissions by 2030 and striving for a substantial 50% reduction specifically in maritime transport emissions by 2050 (IEA, 2022). These recommendations align with the global commitment to combat climate change and underline the vital role of the naval sector in achieving sustainable and environmentally friendly transportation solutions.
Due to the increase in fossil fuels, in human industrial activity and the growing energy demands caused by population growth (United Nations, n.d.), this reduction will be possible mainly through the use of technologies aimed at reducing emissions, based on the decarbonization of energy sources, as is the case of the use of alternative energies and electric power in the system (McKinsey & Company, 2021). Although in the fluvial and maritime mode the inclusion of these technologies, such as electric energy is just incipient, due to the low electrification of ships and cargo vessels (Balcombe, 2019;Xuanet al., 2022), to achieve the proposed environmental goals it is necessary to propose initiatives for the inclusion of this technology to encourage and motivate the transition to these new motor sources.
In search of the above, it is possible to find policies and programs around the world, that seek to encourage the inclusion of electric energy in maritime and river transport modes, which can arouse the interest for different actors and entities involved in transport to opt for including these technologies in their processes, such as incentives that grant financial resources (Kim, 2022;Backer et al., 2020) for the acquisition of these technologies, the reduction of port tariffs (Backer et al., 2020) or obtaining tax subsidies (Port of Stockholm, 2022), among others.
In general terms, subsidies, discounts and project financing programs by governments and private institutions are mechanisms that instead of charging polluters, encourage them to find ways to obtain grants, low-interest loans, discounts or tax exemptions, among others, as a reward for using new methods or technologies to reduce pollutant emissions (Camargo, C. et al., 2022).
To present different alternatives of incentives granted internationally by governments and other private institutions, this paper conducts a search in different countries of such ways to economically encourage the penetration of electric power in maritime and river modes around the world. This work is derived from the research entitled Ferrofluvial 4.0, funded by the Mining and Energy Unit -UPME and the Ministry of Science, Technology and Innovation of Colombia, with the objective of: Formulating a plan for the penetration of electromobility in the rail and river modes for both cargo and passengers, through the evaluation and prioritization of technological alternatives in order to generate a roadmap that strengthens the productive linkages of the country in the medium and long term.
The identification of economic incentives at the global level is fundamental for the Colombian government and other countries to be able to deploy policies and programs aimed at getting stakeholders to appropriate these technologies and thus achieve the environmental commitments agreed upon at the national and international level.
To find different financing mechanisms to encourage the use and development of electromobility in Colombia in the maritime and river modes, an analysis was made of these actions in different countries of the world considered as a reference for Colombia and which are recognized for their performance in this area.
The countries in which information was sought were Colombia, Argentina, Brazil, Ecuador, Chile, Uruguay, Costa Rica, Sweden, Norway, Spain, Germany, Holland, the United States, Canada and Japan.
Through extensive research in official government documents, as well as institutions and organizations within the transportation sector, a meticulous analysis has been conducted. Additionally, a wide range of technical reports and scientific articles related to the topic have been considered. This rigorous approach has enabled the identification of various incentives implemented in different countries. Based on these findings, a comprehensive proposal of short-term, mediumterm, and long-term incentives has been developed to stimulate the adoption of electromobility solutions in Colombia. These initiatives aim to drive a transition towards a more sustainable transportation system, providing economic and environmental benefits in the process.
It is crucial to recognize that this proposal is built upon successful international experiences and takes into account the specific characteristics and needs of Colombia. By incentivizing the penetration of electromobility in the country, significant economic advantages can be achieved, such as reducing dependence on fossil fuels. Moreover, it will make a substantial contribution to greenhouse gas emissions reduction and climate change mitigation, aligning with global sustainability commitments.
As a result of the review of possible incentives applicable in the maritime and river mode in 15 countries analyzed, it was not possible to find economic support alternatives in Colombia, Chile, Ecuador and Uruguay. The incentives found in the rest of the countries are: In the Latin American context, incentives were found granted in Argentina through Resolution No. 50 of 2017: Bonus for sustainable ships 1 -General Ports Administration, which offers discounts between 5% and 10% to vessels that have low gas emissions and are environmentally friendly.

Possible incentives acquired from electric charging infrastructure benefits.
The incentives presented in the previous section are those found specifically to enhance electromobility in river and maritime modes. However, it is possible to find a set of incentives associated with the recharging infrastructure in these countries that, although they are mostly aimed at land transport, can serve as a guide to produce incentives in river and maritime modes. Among the initiatives found along these lines, the most common were: In Brazil, Resolution 819 of 2018 27 was found, which allows those interested in providing the service (distributors, gas stations, shopping centers, ventures, etc.) to charge for the electric car charging service. In Uruguay, the Regulatory Decree 02/12 of Law 16.906 28 allows the exemption from Wealth Tax of fixed assets included in paragraphs A) and B) of Article 7, acquired as from the effective date of this law. The referred goods will be considered as taxable assets for the purposes of deduction of liabilities and generates an exoneration of the Value Added and Specific Internal Taxes, corresponding to the import of the goods referred to in the previous paragraph, and refund of the Value Added Tax included in the acquisitions of these goods. Decree 57/022 -UTE Commercial Discount 29 , which allows the change of the contracted power at no cost, off-peak tariff (0 to 7AM) at 50% in UTE recharge stations, medium consumer and double residential tariffs at 50% in off-peak hours (from 6 to 10 PM).
In Ecuador, the National Finance Corporation 30 will cover 70% of the costs of new projects and up to 100% of expansion projects, while the Organic Energy Efficiency Law (LOEE) 31 offers preferential financing conditions for energy efficiency projects. The regulation will establish preferential rates for public and private electric transportation and incentives for a 10-year period to encourage the use of electric vehicles, such as exempting these vehicles from traffic restrictions due to congestion. In the United States, the Energy Efficiency 2021 program was found 34 , which is a Zero Emission Airport Vehicle and Infrastructure Pilot that provides financing to airports for up to 50% of the cost to acquire ZEVs and install or modify the supporting infrastructure for the acquired vehicles. It also allows financing of up to 80% of project costs and will be available for both development phase planning activities and the acquisition and installation of alternative fuels or charging infrastructure.
In Canada, the BC Hydro 35 could be found which offers incentives in different categories such as: rebate of up to 50% of the costs to purchase and install an eligible Level 2 EV charger, up to a maximum of $700 for single-family homes, including duplexes and townhouses with private garages or dedicated parking; rebate of up to $3,000 for the creation of an EV Ready plan for Apartment Buildings and condominiums; reimbursement of up to $4,000 per charger, up to a maximum of $14,000, to purchase and install Level 2 on-grid electric vehicle chargers for workplaces; and reimbursement of up to 75% of eligible EV charger purchase and installation costs for Indigenous communities.

In the Netherlands there is the Environmental Investment Allowance for Companies (MIA) 50 which is a subsidy that allows the company to deduct a percentage of its investment costs from taxable profit. This is in addition to regular depreciation. And as a result, the company pays less tax. The percentage of the deduction depends on the company's operating assets and the environmentally friendly investments that qualify on the Environmental List among them. Using the MIA, companies can receive an investment deduction of up to 36% of the amount invested in a charging point.
In Germany you can find the Kf W-Bank Incentive for charging stations (private) 51 which grants a subsidy of 900 euros per charging point, the Program: Public charging infrastructure for electric vehicles in Germany (2021 -2025) 52 , which, according to the type of grid connection the financing can vary up to a maximum amount of 10,000 euros. And depending on the type of charging point the installation can be financed up to 60% which is equivalent to 20,000 euros and the NRW-FÖRDERUNG, North Rhine-Westphalia 53 which depending on the type of applicant and the characteristics of the system, the financing can be up to 1,500 euros.
In the UK there is the EV charger grant for homes 54 which offers a subsidy of up to 75% of the total cost of purchasing and installing EV chargers for the home. Company cars and leased cars can also apply for the incentive and the On-Street Residential Charge point Scheme (ORCS) 55 in which local authorities can receive a grant to partially fund (75%) the capital costs associated with the purchase and installation of on-street EV charging point infrastructure in residential areas 56 .
In Japan there is a subsidy for the purchase and installation of charging points -Tokyo 57 that allows subsidizing the purchase cost of charging equipment, construction and installation costs, energy conversion equipment, solar energy generation systems and storage batteries, as well as equipment operation costs.
From the review of incentives, a total of 26 economic incentive programs and initiatives were found to promote electromobility in maritime 53 NRW-FÖRDERUNG. and river modes in the countries analyzed. The country with the highest number of incentives was the Netherlands with a total of 5 initiatives, followed by the United States with 4 and Canada, Germany and Japan with 3 each. Sweden had 2 incentives and the rest of the countries (Argentina, Brazil, Costa Rica, Norway, Spain and the United Kingdom) had 1 initiative. In these initiatives it was possible to find different types of incentives, which can be grouped into the following typologies: • A: Discounts to vessels in ports (port taxes/ traffic rights) • B: Financing equipment or infrastructure for electromobility • C: Tax exemptions/reductions • D: Guarantees and special procedures for electromobility projects • E: Financing to port authorities Table 2 shows the implementation of these incentives in the countries analyzed (using the above notation), from which the most recurrent type of incentive are discounts to vessels in ports (port fees/circulation rights), followed by the financing of equipment or infrastructure for electromobility and tax exemptions/reductions. While examining the economic incentives, various certification programs were identified, which serve as evidence of the vessels' ecological contributions. These programs are utilized by authorities to determine eligibility for the aforementioned economic benefits. The identified certification programs include:

Blue Angel
One notable environmental certification is the renowned German label, which serves to assess the ecological performance of services and ensures that transactions are carried out without significant adverse effects on the environment [19]. BlueAngel certification encompasses various activities, including the operational aspects and design considerations of ships (Blue Angel, n.d.). This certification allows stakeholders, including authorities and consumers, to identify and support environmentally friendly shipping practices. Additionally, this certification program holds immense value in the realm of sustainability, transportation, and economics.

Clean Shipping Index (CSI)
The Clean Shipping Index (CSI) serves as a valuable tool in assessing ships based on their air and water emissions, waste management practices, and staff training initiatives. This comprehensive evaluation goes beyond regulatory requirements and measures the environmental performance of vessels. Depending on the scores obtained, ships can receive certification ranging from one to five stars, with five being the highest score (Clean Shipping Index, 2022). This certification system plays a crucial role in promoting sustainability within the shipping industry. It is essential to highlight the significance of the Clean Shipping Index in driving environmental responsibility in maritime operations. By evaluating various aspects of a ship's performance, including emissions and waste management, the CSI incentivizes companies to go above and beyond regulatory compliance. This promotes the adoption of cleaner technologies, fuels, and practices, ultimately contributing to a greener and more sustainable shipping industry.

The Green Award
Green Award is a renowned certification program that prioritizes safety, security, and environmental considerations within the shipping industry. It acknowledges and incentivizes adherence to rigorous environmental and safety standards. The certification process encompasses a wide range of environmental impacts, including air emissions such as sulfur oxide (SOX), nitrogen oxide (NOX), carbon dioxide (CO2), and particulate matter (PM/BC). Additionally, it addresses issues related to energy efficiency, antifouling paints, oil management, lubrication of mooring ropes, and other deck equipment. Furthermore, Green Award evaluates emissions to waters, such as ballast water, sewage, sludge, bilge, and waste management (Green Award, 2022).

Environmental Ship Index (ESI)
The Environmental Ship Index (ESI) is a tool that was established by the World Ports Climate Initiative in 2011 to help reduce emissions of NOX, SOX, particulates, and CO2. The scoring in the ESI system is based on the emissions of these gases as well as the vessel's ability to use shore power supply. To receive a score in the ESI system, the vessel must have emissions that are lower than the legal requirement for NOX and SOX. The ESI score ranges from 0 to 100, with a higher score indicating better environmental performance (ESI, 2022).
Colombia is positioned as one of the Latin American countries with more development of electromobility policies and benefits granted to acquire electric vehicles in the road mode. However, this commitment is null for maritime and river modes, since there are no incentives in the country to promote electromobility in these modes of transport, except for a project initiative in the Amazon River that seeks to implement the use of boats powered by electric motors or solar panels. It is therefore necessary that this good practice in the road mode be extended to other modes of transportation.
A good way forward is to adopt the initiatives and incentives that other countries are implementing and that can be applicable to some specific regions of the country or in the country in general, considering the orientation and objectives that Colombia has set for itself in terms of greenhouse gas reduction. Among the aspects to be prioritized in these incentives are the development of infrastructure, modernization of passenger transport fleets, recovery of docks, science, and technology projects. Taking as a basis some of the incentives that are in force or that have been implemented in other countries can represent an advantage to design incentives that can bring benefits for the economy, the environment and society.
Based on this analysis of incentives, the following incentives can be proposed for Colombia (See Table 1), which are presented for different time horizons and include the percentage of financing, discount, or exemption for the aspects to be favored in the maritime and river modes.

Financing of research projects. 100% 100% 100% Financing of river projects up to 70% of the project by the national government 70% 70% 70%  Zapata, Paipa, Aguirre, Camargo In the review different initiatives and actions were found in the analyzed countries aimed at generating incentives for electromobility in river and maritime transportation, thus allowing the migration to environmentally friendly modes of transportation. A total of 26 different initiatives were found, most of which were aimed at generating discounts in ports for the use of environmentally friendly vessels, as well as financing projects for the acquisition of equipment and infrastructure and tax reductions.
This article demonstrates the interest of different countries in promoting electric mobility in maritime and river modes, finding more incentives in one country than in another, but in any case, it is an important commitment to generate sustainable transport systems. In the case of the Latin American countries studied, only in Brazil, Argentina and Costa Rica were initiatives of this kind found, which is an opportunity for the other countries to follow suit.
The regulations and policies on electric mobility in Colombia are oriented towards the electrification of road transport and there are no incentives to promote electric mobility in the maritime and river modes. Nor were any incentives identified that could favor the development of maritime or river electric cargo infrastructure. In order to strengthen this aspect, a set of short-, medium-and long-term incentives were proposed to favor investments in this area in the country.
As future work, there is a potential to expand the analysis to encompass additional countries, thereby uncovering alternative forms of initiatives and incentives. Furthermore, it is crucial to conduct further research to identify the financing mechanisms available to governments, which would facilitate the implementation of these initiatives and incentives. Understanding the avenues through which governments can secure funding is essential for effectively materializing such endeavors.
It is imperative to emphasize the importance of broadening the scope of analysis to gain a comprehensive understanding of the global landscape. Exploring initiatives and incentives implemented in diverse countries can shed light on innovative approaches and best practices that can be adapted to local contexts. Additionally, investigating the financing mechanisms will enable governments to allocate resources effectively and foster the development of sustainable transportation systems.
By expanding the analysis and delving into the financial aspects, researchers and policymakers can foster the creation of a supportive environment that encourages the generation and implementation of impactful initiatives and incentives in the transportation sector.
