Ecopoint

Ecopoint

The Ecopoint represents the total potential environmental load of a product or solution: it is a cumulative, more holistic value that includes the impacts on human health, the ecosystem and resource diversity. The single numerical score of Ecopoint represents the overall impact of a product or solution. This score can be interpreted as a measure of sustainability performance, where lower scores indicate lower environmental impact.

The Ecopoint therefore allows us to group the 9 other environmental indicators in three different categories of damage: (1) Human Health, (2) Ecosystem quality and (3) Resources. This way, obtaining a single score representing the total environmental impacts during the product's life cycle is possible.

Human Health and Ecosystem Impact

The ecopoint index factors in the impact on human health and ecosystems, how a product's life cycle may affect human well-being including health risks related to exposure to pollutants, and how it may impact ecosystems, including biodiversity and habitat disruption.

Resource Diversity

This takes into account the diversity and availability of natural resources, as well as the potential depletion of non-renewable resources and the consequences for future generations.

The Ecopoint index is essentially a form of multi-criteria assessment that allows decision-makers to weigh different environmental and sustainability factors. It acknowledges that environmental issues are interconnected, and a single value can provide a more comprehensive understanding of the trade-offs and impacts associated with a product.

Photochemical Oxidation

Photochemical Oxidation

On Earth, pollution mixed with heat and sunlight creates a concentration of Ozone (O3 gaz) in the atmosphere (stratosphere + troposphere). This gaseous element, when released in the stratosphere, acts like sunscreen for all living organisms, shielding the Earth’s surface from most of the sun’s UV light (unless it creates depletion in the atmospheric layer).

However, when this concentration remains at ground level in the troposphere, it affects the air that we breathe as humans and therefore starts becoming a health hazard. When inhaled, ozone reacts chemically with many biological molecules in the respiratory tract, leading to a number of adverse health effects.

We call this secondary air pollution Photochemical Oxidation, also known as Summer Smog. Chemically speaking, photo-oxidant formation is a photochemical creation of reactive substances: it is formed in the atmosphere by nitrogen oxides and volatile organic compounds in the presence of sunlight, often the consequence of emissions from fossil fuel combustion. POP calculates the destructive effects of ozone in the troposphere over a time horizon of 100 years.

X
Global Warming

Global Warming

The Earth receives energy from the sun through solar radiation, with about half of this energy being absorbed by the earth’s surface. The other half is reflected back into the atmosphere as infrared radiation or heat. Greenhouse gases (GHGs) trap this radiation in the atmosphere, thereby heating the Earth. Consequently, the more GHGs that are present in the atmosphere, the warmer the Earth’s temperature becomes. This process is known as the greenhouse effect.

In order to make meaningful comparisons between GHGs, scientists have adopted CO2 as the benchmark for measuring their heat-trapping abilities. CO2 is a clear, odourless gas produced during carbon combustion and in the respiration of living organisms. The heat-trapping potential of a gas, measured against CO2 over a fixed period, is known as Global Warming Potential (GWP). CO2 is used as a benchmark to measure the GWP of substances, which is expressed in kg of CO2eq.

Ultimately, GWP evaluates the potential impact of different gaseous emissions on climate change by calculating the radiative force over a 100-year time horizon.

X
Ozone Layer Depletion

Ozone Layer Depletion

In the stratosphere, an ozone-rich layer called the Ozone layer exists. The formation of the ozone hole is directly linked to the stratosphere’s temperature. Once temperatures drop below -78°C, polar stratospheric clouds tend to form, exacerbating ozone depletion over both of the Earth’s hemispheres.

The Ozone layer acts like sunscreen for all living organisms, shielding the Earth’s surface from most of the sun’s UV light. Its depletion could cause serious damage for humans, animals, plants and materials. Ozone Depletion Potential (ODP) calculates these destructive effectives over a time horizon of 100 years.

X
Acidification

Acidification

Acidification is an environmental problem caused by acidified rivers/streams and soil due to anthropogenic air pollutants such as ammonia, nitrogen oxides and sulphur dioxide. When acids are emitted, the pH factor falls and acidity increases, which for example can involve the widespread decline of coniferous forests and dead fishes in lakes in Scandinavia.

In the ocean, we define acidification as a reduction of the pH over an extended period of time, and it is caused primarily by an uptake of carbon dioxide (CO2) from the atmosphere: the ocean absorbs the extra amount of CO2 emitted in our atmosphere. We are already observing this change in the deep ocean, especially at high latitudes.

It affects marine organisms, with a consequence on the ecosystems they belong to in and above water: disrupting the food chain (increase of the mobilisation and the leaching behaviour of heavy metals in soil), altered prey availability (for example, krill for whales), impact on habitats (lower pH destroys coral reefs), but also the amplification of noise pollution by a modification of the underwater acoustics.

As an indicator, Acidification Potential calculates the impact of the potential change in acidity in the soil due to the atmospheric deposition of sulfates, nitrates, phosphates, and other compounds.

X
PM10

PM10

Dust from roads, farms, dry riverbeds, construction sites, and mines are types of PM10: particulate matter with a diameter of 10 micrometres or less. These are coarse (bigger) particles, which can irritate your eyes, nose, and throat. While fine (smaller) particles (PM2.5) are more dangerous and penetrate into the deep parts of your lungs — or even into your blood, it is important to measure the level of PM10 into the surrounding air.

Scientists have defined that a level of PM10 below 12 μg/m3 is considered healthy with little to no risk from exposure. If the level goes to or above 35 μg/m3 during a 24-hour period, the air becomes unhealthy, causing a risk exposure for people with existing breathing issues such as asthma or lung diseases.

With deposits accumulating onto surfaces, including vegetation, soil, and water bodies, PM10 also impacts soil erosion, water quality, aquatic life cycles, and can carry contaminants into ecosystems. It can lead to winter smog.

Water Scarcity Footprint

Water Scarcity Footprint

The water scarcity footprint helps assess how particular water use contributes to or exacerbates water scarcity in a given area. We assess this impact by considering the quantity of water consumption and the water stress index (WSI) of the region from where the water is extracted, to determine the impact of freshwater consumption in view of its deprivation potential.

Water Stress Index for yachting

In yacht manufacturing for example, water consumption is significantly high for the extraction and production of materials. The amount of water consumed when producing yacht-building material is more than double than during the operating phase of the yacht. Further, hull construction requires water in various stages such as composite-moulding process, curing resins, and more. While these stages do not use large volumes of water individually, they become high over the course of yacht production. The water stress index can thus be an important metric in quantifying how much water is consumed and identifying hotspots where efforts to minimise water use can be implemented.

The Water Stress Index takes into account factors like available water resources, population, and industrial demand for water in that area. Of course, water resource exploitation may have a different impact depending on the extraction area.

Water scarcity impact

If the water scarcity impact is high, it indicates that your product or solution is exerting considerable strain on an already water-stressed region. Consequently, it may be prudent to explore more sustainable water sourcing or conservation measures to mitigate one’s heightened environmental damage. Conversely, if the water scarcity impact is low, it suggests that your product or solution exercises a relatively minor impact on water scarcity in that region, which can be a positive indicator of sustainability.

The indicators for WSI reflect the cumulative amount of direct and indirect emissions to help us understand how a product or solution’s water use might impact water shortages.

X
Eutrophication

Eutrophication

Eutrophication calculates the destructive effects of ammonia, nitrates, nitrogen oxides and phosphorus (emitted in air and waters) on freshwater systems. In inland waters, it is one of the major factors that determine the ecological quality of an aquatic environment.

This process of pollution occurs when a lake or stream becomes over-rich in plant nutrient – as a consequence, phytoplankton increases, and the water becomes overgrown in algae and other aquatic plants. The plants die and decompose, robbing the water of oxygen so that ultimately the lake, river, or stream becomes lifeless.

While eutrophication occurs naturally in freshwater systems, man-made eutrophication occurs over millions of years and is caused by organic pollutants from man’s activities, like effluents from industries and homes.

X
NOx

NOx

NOX are a group of highly reactive gases produced by various natural and anthropogenic (human-caused) sources. They strongly affect the air quality in our immediate surroundings, leading to the formation of ground-level ozone and fine particulate matter, and contributing to acid rain or deposition, ozone depletion, and eutrophication of soil and water.

We know that the subsequent impacts of acid deposition and eutrophication onour soil and water can be significant, having adverse effects on aquatic ecosystems in rivers and lakes, damage to forests, crops and other vegetation. Furthermore, by contributing to the formation of atmospheric aerosols and particulate matter, NOx emissions can lead to the formation of nitrous oxide (N2O), a potent greenhouse gas that contributes to global warming and affects human respiratory systems. When the environment is affected by NOx, it results in Summer smog, Winter smog, and Acidification in the environment impacted by its release.

X
SOx

SOx

Sulphur dioxide (SO2) is a colourless gas with a pungent odour, released into the atmosphere from both natural sources, such as volcanic eruptions, and anthropogenic (human-caused) sources emitted by the combustion of fuels containing sulphur.

Sulphur dioxide is a pollutant that contributes to acid deposition, which, in turn, can lead to potential changes in soil and water quality (eutrophication due to excessive nutrient input, as discussed above). Its effects can be counterbalanced by implementing flue gas desulfurization systems in power plants, and regulations on emissions from transportation sources. Winter smog and acidification are among the results of its presence in our atmosphere.

Code of Conduct

Our Code of Conduct confirms the collective approach but also sets
out the influence and responsibility that individuals have.

Decade of Sustainability

As the superyacht industry entered 2020, the beginning of a decade we coined as the ‘Decade of Sustainability in Yachting’, we were excited to launch the very first industry-wide Code of Conduct. If you’re not familiar, a code of conduct sets out the rules and responsibilities of an individual or an organisation.

Our Code is made up of ten commitments that, when implemented and adhered to in daily practice, will make a real difference in reducing the environmental footprint of the superyacht industry and restoring our precious oceans. Those that sign our Code of Conduct know what is being expected from them, commit to these principles and know that fellow signers do the same and can be held accountable if they do not.

We’re stronger together, but individually, we each have the power to make a difference. That’s why our Code of Conduct confirms the collective approach but also sets out the influence and responsibility that individuals have.

There will be opportunities to sign our Code of Conduct at various industry events.

Signing the Code of Conduct

You can sign our Code of Conduct online. We ask that it is signed by only one senior representative from each company. When major industry events have resumed, there will be opportunities to sign our Code of Conduct there too.

Our signatories

Senior management from more than 30 companies have already signed our Code of Conduct, cementing it as an important step in the path towards the superyacht industry becoming sustainable.

1. We recognize that, as the superyacht industry, we owe it to our strategic position to drive change.
The superyacht industry is in a unique strategic position. We are blessed with extraordinarily influential clients who have the ability to drive sustainability and make a truly positive impact. By co-creating cutting-edge innovations that find their way to other (maritime) industries, the superyacht industry can function as Formula 1 functions to the car industry. Each new build project should be viewed as an opportunity to develop and embrace technology that pushes the boundaries, reducing the otherwise long time-to-market of such inventions. New technologies can also be installed during maintenance and refit operations of the existing superyacht fleet in order to upgrade existing yachts. With clients that can make a real difference, we are in a strategic position to facilitate this.
2. We are determined to protect the oceans from degradation, to support ocean conservation, and to leave the oceans in better shape than before.
The oceans are the most critical natural resource for the superyacht industry. They are irreplaceable and technology cannot provide a substitute. The statistics are sobering. Oceans absorb 30% of the CO2 that is released into the atmosphere. However, as the CO2 levels in the atmosphere rise, the levels in the ocean do too, increasing their acidity and affecting many ocean species (National Oceanic and Atmosphere Administration). We must take action now. Not only to ensure the future of our industry, but that of life on planet Earth.
3. We respect the oceans as they are a crucial stakeholder of the superyacht industry.
We sail the world’s oceans to enjoy the beauty of nature. Without a healthy ocean to enjoy, there is little reason for yachting. In this way, the superyacht industry is the only maritime sector that directly depends on the health of the oceans. The healthier the oceans, with flourishing marine life and colourful corals, the more attractive yachting becomes. Oceans are therefore crucial stakeholders to our industry, and it is time we treated them as such by becoming stewards of these life-supporting systems.
4. We commit to sustainable consumption of natural resources and impact-free production to meet the needs of the present and future generations.

It goes without saying that harming nature or polluting oceans is directly in conflict with that what drives our industry. It’s our responsibility to ensure yachting is free from negative impact and nurtures its most important natural resource: the oceans.
As an industry, we use natural resources which we need to manage responsibly. Luxury should not come at the cost of nature or add to the endangerment of species. At all times, we need to refrain from exploitation and negative impact on nature and local communities that could cause conflict.

5. Each person and organisation take individual responsibility from their position to drive positive change.
Get started now. There is a lot that can be done, even from your own backyard. We all have the responsibility to continuously improve on what is within our direct reach. We each have more influence than you may think, not to mention how we can inspire or help others.
6. We actively propose sustainable solutions to our clients and demand sustainable solutions from our suppliers.
We are all part of the supply chain that makes up the life cycle of a yacht. We are impacted by the person in the chain before us and our decisions impact those after us. It’s important that we realize that the choices we offer, or decisions we take, will affect the rest of the supply chain. At the same time, we are all in a position to request a better product or service from our suppliers. This will have a snowball effect and result in a more sustainable superyacht industry.
7. We support the mission of Water Revolution Foundation and embrace its sustainable solutions and tools to drive sustainability in the superyacht industry.
To future proof the superyacht industry, reducing our environmental footprint and preserving the world’s oceans is vital. Water Revolution Foundation started from within the superyacht industry in order to provide the platform for collaboration and to develop the tools needed to drive sustainability. To succeed, the superyacht industry must collaborate and coordinate, setting standards and sharing solutions, working with the same set of tools and in the same direction.
8. We recognize that our future is relevant only when we conduct business in a sustainable way, sharing knowledge and information in order to reduce the superyacht industry’s environmental footprint.
There is no plan B for the planet, nor a plan B for the superyacht industry. While we cater to a very niche market, this is no excuse, nor is it a reason for exemption. In fact, it gives us more responsibility to utilize our unique position. We need to overcome our reservations and realise the potential of sharing knowledge and information. Together we can achieve more, and faster.
9. We embrace the UN 2030 Agenda for Sustainable Development as the foundation for our plan of action for people, planet and prosperity.
The world is rapidly waking up to the consequences of unsustainable use of natural resources and pollution caused by human behaviour. The superyacht industry cannot be an exception to the internationally-coordinated efforts and needs to align itself with the Sustainable Development Goals set by the UN so that we can turn the tide before it is too late.
10. As we embark on this collective journey, we take the responsibility that everyone in this industry is empowered to join our Revolution.
In a sustainable world, no one is left behind as we need each other to make the necessary changes. The same can be said for our industry. In order to future-proof our industry, we must work together. Sustainability is no competition; it is our responsibility to future generations.
