ZEERO ENERGIES

POWERING A RESILIENT TRAVELLING FUTURE

The "butterfly effect" describes how a single, seemingly small action can set off a chain of events that lead to major change. In the same way, traveller micro contributions can trigger transformative outcomes, driving positive impact across the entire travel and tourism sector.

ZEERO unifies isolated efforts, shifting from fragmented climate actions to a shared, industry-wide commitment, channelling contributions into a steady flow of funding to support globally scalable infrastructure, biofuels, and regenerative solutions. This model delivers measurable environmental and community benefits for destinations around the world, enabling travel brands to communicate credible, purpose-driven narratives that strengthen resilience, reputation, and long-term value.

Transportation is the second largest emitter of global greenhouse gases at ~15%. Among the fastest-growing contributors are aviation and shipping, both expected to expand significantly in the coming years. These sectors pose unique decarbonization challenges due to the technical limitations of alternative energy sources and the sheer scale of fuel consumption involved. Road transport is the biggest emitter within the sector, accounting for more than 70% of all GHG emissions.

ZEERO SOLVES MULTIPLE ENVIRONMENTAL CHALLENGES

The transition away from fossil fuels has become a focal point in the global agenda. However complete independence from fossil fuels cannot be achieved without the implementation of renewable energy but also biofuels. In 2024, the G7 countries published a joint statement "sustainable biofuels can and must provide a fundamental contribution to the decarbonisation of the transport sector at a global level."

ZEERO's initial energy project focuses on two critical global challenges

WASTE management and EMISSIONS reduction

through a Hydrothermal Liquefaction (HTL) technology.

HTL takes sewage, agricultural waste and other biomass waste materials and converts it into circular liquid biofuels. This new generation of biofuel technology is a proven and patented technology requiring little-to-no precious resources such as fresh water or arable land. The HTL plants produce the following biofuels:

45% Biodiesel, 25% SAF Sustainable Aviation Fuel, 16% Gasoline, 14% Heavies.

81% lower in emissions than fossil fuels

HTL technology is able to assist in the decarbonisation of heavy transport and energy sectors (aviation, shipping, road and rail transport, power generation) and bring energy independence to communities while keeping existing vehicles and infrastructures in place.

A GLOBALLY REPLICABLE CIRCULAR SYSTEM

Aviation is the hardest form of transport to abate in terms of greenhouse gas emissions, especially for long-haul flights, and demand is growing. The EU’s ReFuel Aviation Regulation requires the use of Sustainable Aviation Fuel (SAF), which includes biofuel and synthetic fuel, with a 2% quote in 2025 rising to 70% by 2050. The UK SAF Mandate requires 2% in 2025, 10% by 2030, and 22% by 2040.

Regarding the cruise industry, in 2024 there were 34.6 million passengers, by 2027, cruise is forecast to grow to nearly 40 million passengers. In April 2025, The International Maritime Organization (IMO) introduced a mandatory emissions reduction framework. Cruise ships may face penalties of up to US$378 per tonne of greenhouse gases emitted. This could amount to US$2.6 million per day for a large cruise company. The IMO suggests that investing equivalent funds into biofuel development over a decade could eliminate the need for fossil fuels and provide fuel cost stability.

On the road, while Euro 6 standard comes with low emissions, long-distance coaching is still dependent on these diesel-powered vehicles. While electric vehicles are becoming more widely available and a practical option in terms of range for day services, production of lithium-ion batteries and electric motors dependent on rare-earth metals come with environmental and geopolitical problems. Up-front cost of vehicles - assuming there is sufficient supply - is prohibitive for many, even though lifetime running costs may be significantly lower. Hydrogen fuel cells creating electricity may prove a more viable alternative long-term, especially if the hydrogen is produced by off-peak renewable energy, but costs remain high and availability scarce.

THE ENVIRONMENTAL & ECONOMIC IMPACTS OF WASTE

Along with agricultural practices and rural land management, sewage is a major contributor to the declining ecological health of seas, rivers, and waterways worldwide. As populations grow, including tourism surges in popular areas, and extreme weather events become more frequent and intensify, sewage systems are struggling to keep up. While wastewater treatment facilities are designed to occasionally overflow, these overflows are becoming more frequent, posing escalating risks to both public health, the environment, as well as local businesses.

WASTE TO FUEL : REPURPOSING SEWAGE & BIOWASTE

While crop waste can be used for heat, power or biofuel feedstock, crops grown for fuel can affect capacity for food production, and cause harm through land-use change. These risks were addressed in criteria for biofuel production set out by the European Commission in 2019 in the context of the 2018 Renewable Energy Directive. Updated rules published in 2023 cover a range of feedstocks, including recycled carbon fuels. Given the impact of state aid rules on member state biofuels initiatives, the European Commission’s July 2025 recommendations for tax incentives to accelerate transition in support of the Clean Industrial Deal was welcome.

Biofuels potential is growing with the emergence of modern production technologies like Hydrothermal Liquefaction (HTL). HTL biofuels are not only more cost-effective to produce, but they are scalable due to the organic waste feedstocks and sewage, making them eligible for subsidies that can significantly reduce their market price—potentially bringing them in line with fossil fuels. As legislation increasingly imposes penalties on fossil fuel usage, the cost gap is expected to narrow, making biofuels more competitive. Since biofuels are among the most immediate effective tools for decarbonizing transportation, demand from the travel and transport industries is strong. Yet, scalability remains a challenge, especially at lower costs—underscoring the importance of accelerating HTL adoption.

BLENDED FUNDING TO ACCELERATE & SCALE

ZEERO’s HTL biofuels will be financed through a blended funding model, drawing from a mixture of sources; municipalities, local partners, climate contributions from the tourism sector and fuel offtake agreements with airlines, cruise and coach tour operators, helping to drive a long-term steady stream of funding towards the HTL projects, creating a self-reinforcing circular bioeconomy. This Public-Private Partnership (PPP) model fosters direct collaboration and benefit-sharing.

COLLABORATION DRIVING POSITIVE CHANGE

The travel industry stands at a critical juncture. The travel industry is an interconnected ecosystem: airlines, cruises, rail, road services and hotels are mutually dependent, meaning that decarbonization failures in one area have ripple effects across the entire sector. Climate change is not a future threat—it is a material, present-day business risk. Regulatory pressure, environmental costs, and infrastructure challenges all demand immediate and coordinated action across sectors and industries.
