Net Zero Energy hotels, it always seems impossible until it's done ?

Why is transformation/disruption required ?

40% of global emission of CO2e are related to the building sector.

Standard sustainability practices in the hospitality industry are presently geared toward reducing waste of food and water plus subtile savings on the consumption side of energy. Few initiatives exist to lower carbon footprint on the power generation side. Those are too modest to make an impact.

- A few dozens of hotel worldwide are purchasing Carbon Credits supposed to offset the carbon footprint of operations. However price of carbon credits on the unregulated free market has plummeted due to international malpractices on the supply side (down to a meaningless 3USD per ton of CO2e !!!). Therefore most offset programs are nowadays evaluated as cheap green-washing with no or minimal redeeming benefits.

- A meaningful however modest initiative, the Nearly Zero Energy Hotels, is a "middle of the way" label supported by the European Community. It usually translates into renewables powering on-site 20% - 30% of energy needs, of heat pump(s) inserted into the central heating system,of additional layers of insulation and of improved airtightness, the three later actions to reach the nearly passive building grade . . Up to now, only 16 european hotels, mostly small or midsized, have joined the responsible program.

- Finally, on islands and other remote off-grid locations, we can find a small number of lodges and hotels, who instead of using diesel generators 24h/24h, opt for a mix of diesel, biomass, solar panels, wind turbines, and batteries. A few small-sized developments are also taking the responsible direction of harvesting a fair share of energy from their ground despite being connected to a power grid.

Worldwide, less than one thousandth (<< 0.1%) of energy used in the hospitality industry originates from power harvested on real estates of hotels and resorts. The 2018 sustainable hospitality survey from Cornell University, shows that out of 8000 global hotels reporting on voluntary basis, only 10 units derives 50% or more of their energy from on-site harvesting.

Where does it REALLY matter for the planet?

It matters the most in countries where our hotels burn lots of carbon !

In developed countries as general, fossil fuels represents nowadays a decreasing portion of the electricity mix. Therefore, at the important exception of USA, hoteliers could be forgiven for focusing on savings and for relying on the state and public/private utilities to progress toward decarbonized energy.

The reasoning shall be opposite in developing countries. There, electricity needs are surging above 7% yearly. Because coal, abundant and discarded by developed countries, is nowadays so cheap, and because natural gas is costly to liquefy and transport, developing countries mostly rely on the construction of massive coal and gas power plants to fill up the demand in affordable electricity for their economy and their population.

In dozens of major tourism destinations like China, India, Vietnam, Malaysia, Indonesia, Central Europe, several African countries, electricity derives 70%-80% from coal, at a frightening environmental cost of 1 ton of CO2 per MegaWatthour !! (In other important tourism destinations like Thailand and Middle East electricity derives mostly from natural gas, at a significant cost of 550 kg of CO2 per MWh).

Ie: The average carbon footprint of electricity in India and China are 0.86 ton and 0.76 ton of CO2e per MWh respectively, against 0.29 ton in Spain (wind & solar), 0.07 ton in Brazil (bioethanol) and 0.06 ton in France (nuclear).

By the same token, renewable energies appear to those states as less dependable and more expensive to produce & carry compared to coal . In most countries, due to low tax collection and unsufficient funding, national commitments to COP15, 16, 17, 18, 19, 20, 21 & 22 always get postponed for the sake of economic growth and of poverty alleviation. For national rulers, cheap coal is a genuine dilemma…

We shall not get fooled by the (real) news that since year 2017 photovoltaic and wind farms are getting constructed at fast pace in the two strongest developing economies, China and in India, thanks to the lower cost of PV panels and wind turbines. Appearances can be deceiving ! Coal power plants are so numerous and so more flexible that, from the most optimistic forecasts, the total of all ramped-up efforts on renewable energies will only cover 15%-25% of the electricity mix in 2030 !! and 45% of the electricity mix in 2050 !!! (as a quick reminder, CO2e budget in atmosphere for +2.0 degrees C temperature increase budget is planned to be consumed by year 2037).

Due to short term priorities, no hope as well can be expected from local communities, villages, towns or regencies (in developed countries, local & regional initiatives are at the forefront of almost all Net Zero achievements, with thousands of new achievements to come within the coming 5 years).

Not less frustrating, with local public activism amazingly low about climate change, legislative and executive bodies aren’t applying much pressure toward national utility companies. Those decade long monopolies are dragging their feet against disruptive change and against share of influence.

Bottom line : for most developing destinations, the ratio of coal in electricity production will unfortunately remain at 50%-55% for the NEXT THREE DECADES !! (The 45%-50% balance being shared among oil and gas, nuclear and renewables). Even worse, due to hectic construction of large coal power plants while sluggish investments in renewables don't catch-up, most developing countries actually burn annually MORE coal, not less, that they were burning 5 years ago !! Grim trend when you think about it...

Here is a 2018 study from the respected company Det Norske Veritas - Germanischer Lloyd, showing that, for developing countries in Asia Pacific, the ratio of Renewable Energy in Electricity will only reach about 15%-25% by 2030 and will barely reach 45% in 2050 !!! Pick "Main Report" and others in the returned email from DNV-GL

This is to everyone, developers, operators and guests, to quickly decide how to reduce those heavy CO2 emission from hospitality. Let's however acknowledge that the excuse of waiting for non-affluent states to firstly provide clean energy is heavily flawed, increasingly irresponsible and is causing serious damages to our planet. In a couple of years environmental groups, international governing bodies, media and consumer lobbies will probably expose that using dirty electricity to lavishly power luxury accomodations, plush shopping malls and high-end offices, moreover at a huge multiple in kwh per person per day, is a WORSE WRONGDOING than the modest use per head for housing, public schools and hospitals needed by the local masses.

At fossil fuel powered destinations, upscale hotels SHALL harvest on their ground.

Hotels are a priviledged class of estates of their own, at least in the middle-high segment.

- For one, we use lots of electricity ! Installed power is huge and often exceeds 25 000 Watt per room !! Consumption fluctuates with occupancy and usage patterns, however in high-end accommodation, typical annual consumption amounts to 450-700 kWh of energy per square-meter versus 30 -152 kWh/m2 for other commercial buildings (Source: University of Technology of Eindhoven ). For large rooms in fossil fuel powered destinations, this causes and will continue to cause the release of 40 tons to 100+ tons of CO2e per room per year !!

Another source, financed by USAID, analyzing 131 hotels in India, brings a similar sorry figure of 400kg of C02e per m2 per year !!. For upscale 5 star hotels where gross room area, including circulations and facilities (lobby, restaurants, spa, etc) averages 150m2 per key, we calculate CO2e emissions at a consistent 60 tons per room per year !!

As a triple check, I was able to get the actual electricity bill of a "green luxury" hotel in Indonesia, country where I live, built from 70 gorgeous one-bedroom private-plungepool-villas in lush gardens, with average room rate of 450 USD/night, communicating worldwide like other upscale chains, on their support to United Nations SDGs by low use of plastic bottles, cooking of organic vegetables, recycling of bathroom water, reusable linen & towels and providing assistance to local villages. Bottom line is a great greenwashing !! The bill of their Indonesian operations happens to be 440 kWh of electricity per day per occupied room !!! At a local carbon intensity of 0,76 tons C02e/GWh (equal to China but lower than India), and assuming a realistic 90% occupation rate, this random-picked "green luxury" hotel emits 110 tons CO2e per room per year !!!! 335 kg of coal being actually burnt by the state for each granted night !!!!!

Each large bedroom uses-up as much as a rural village of 135-350 persons spending a typical electricity bill of 300 kWh/year/person. Depending on the number of rooms, usually ranging from 150 to 300+, a single upscale resort releases each year 6 000 - 30 000+ tons of CO2e !! As much as 150-300+ villages, as much as 20 000-100 000 local persons !! Over a lifespan of 30 years, a single upscale resort may cause the release of one million tons of CO2e !!

To illustrate differently how the hospitality sector in developing countries fails in sustainability related to energy (and water), a 2016 study from Cornell University reveals that, due to the 80% coal content in electricity and due to lavish consumption habits, the carbon footprint of hotels entering in operation in China keeps growing unabatedly to soon reach 150 millions tons of C02 for the sole year 2025 !! (Chinese hotels, 1 to 5 stars, are expected to total 6.1 millions keys by year 2025, for a 96% domestic visitor market). Each year, those are equal to 1.6 times the emissions of a 103 millions people country like Philippines !! Here is the study Environmental Implications of Hotel Growth in China

- Second, most guests, foreigners as well as nationals, tourists as well as businessmen, don’t belong to the low-income demographics of countries where hotels stand. Cheap and subzidized energy is not a selection criteria and given the choice, most guests would prefer clean standards. Conversely, highly carbonized energy also promise to become a highly negative factor for a growing responsible segment of the market.

- Third, high-end hotels and resorts are tiny «man-made states» of their own. Architects, developers, operators enjoy full control on the use of land, on room design, on roofing options, on heating and air-conditioning systems, on energy appliances,...

- Fourth, most upscale hotels and resorts enjoy considerable land space for gardens, planted parks and parking area, and enjoy as well the availability of large roofs.

Bottom line : upscale hoteliers don't need to remain bound by the cheap coal dilemma of destinations where hotels stand. Developers, operators & architects can position resources and drive design to reach a tilting point where buildings save energy better and where on-site self-generation allows a Net Zero status.

We better start creating our own disruption. For the good of future generations, how sustainable would remain the position of global operators and property owners, claiming to operate at low footprint standards in Western Europe & Canada thanks to some favourable energy-mix (and also in USA thanks to massive national offsets)... while actually operating with footprints FIVE TIMES heavier at other places of the SAME PLANET ? The travel and tourism industry is the largest industry on the planet, it is about time acting like it !!

The major concerns of intermittent generation, energy storage and dependability

Although a growing market segment is interested to act responsibly toward waste and energy consumption, guests expect the same continuous flow of electricity, heating & air-conditioning than tap water or wifi connection.

At the exception of micro-hydro, geothermal , seawater turbine or deep seawater cooling, all restricted to uncommon locations, the most prevalent renewables, wind and sun, are heavily intermittent. 

NB: Biomass is not location dependant, even grows on water, can be stored, and biomass growth isn't intermittent either. However, the market of certified biomass (renewable wood, organic oils, organic waste) is at its infancy in most developing countries and, with photosynthesis nett efficiency at only 3%-4% of solar irradiance, then to be divided by a factor 2 in the burning process, the alternative of growing biomass on hotel premises requires excessive space for our industry.

The key is of course to address the issue from the onset.

1) Saving energy is always the less expensive component. To reach a "nearly passive building" grade is an obvious start (super-insulation and airtightness of envelope, minimised area of thermal exchange with outside for heated or AC cooled rooms, exposure to the sun in cold destinations, shading from the sun in warm destinations, LED lighting, presence sensors, training of staff, voluntary involvement of guests).

2) Maximising the offering of semi-outdoor areas, private decks, open lobby & restaurants, pools, gardens, etc… offering several spaces with no need of heating or Air Conditionning, heated by sun, cooled by natural breeze or with low-consumption fans, is a major design component as well.

3) Thermal mass/inertia of building materials is totally underrated. Sensation of heat or cold depends much more on thermal radiation emitted or absorbed by room walls, floor and ceiling than on air temperature itself. Thick concrete and natural stone return back energy with a convenient 4 to 6 hours delay (unfortunately thick concrete shows a detrimental footprint because of the high grey energy of cement production).

4) Since energy for heating and/or cooling exceeds 60% of daily consumption, storage of renewables under the form of thermal energy is a must. Intermittent wind and sun energy can easily be stored in large tanks of cold and hot water, which offer an excellent heat capacity of 4.183 Joule/kg per degree change. Even more efficient, enthalpy of fusion/solidification is clearly a route for the future. Like the ancient use of ice to save food in sailing boats and remote villages, there is now a large choice of biosourced or mineral PCMs (phase changing materials) with melting temperature covering a –20°C to 60°C range , storing sun and wind energy with an excellent enthalpy of storage & restitution of 125-275 kiloJoule/kg, at 99.995% efficiency for 10 000 cycles along an expected 25 year lifespan !!! PCMs can efficiently be included straight into the central heating system and/or into the hot water supply and into the central climatization system, where their solidification and fusion are the easiest to control. In midscale segment, they can also be simply positionned straight into the room to heat or cool the air thanks to a 3°C-5°C stabilization of their own, with dozens of successful examples worldwide.

5) Subject of batteries used to be controversial because they were overly costly, were loosing nominal kiloWatthours capacity after a couple of years and because they produce hazardous waste at disposal. This situation is changing quickly since batteries for 5 000 - 7 500 cycles are now at the doorstep.  According to the World Bank and to several other studies, price of battery storage might drop to 0.05 USD/kWh in 2025 (against 1-2 USD/kWh for year 2010 and 0.14-0.40 USD/kWh for year 2015). A fair capacity of batteries, say 20-30% of a full-day consumption stored in stand-by, is an appropriate answer to smooth-up consumption peaks, to fill-up gaps from renewables, as well as to provide emergency backup for breakdowns of the national grid. With larger batteries, Net Zero hotels, even those completely off-grid, will be able to dump in the future those ubiquitous backup diesel generators.

6) Of course, a mix of two sources of intermittent renewable energies (ie: sun plus wind, or sun plus outsourced biomass, or wind plus outsourced biomass) shows steadier production hours that a site relying 100% on solar panels or 100% on wind turbine. Luckily, in warm countries, sun is shining when electricity for operations and Air Conditioning is at its peak. Yet, this does not guarantee windy nights...

7) National grid is a useful joker card. For one, it replaces a diesel generator as the back-up plant. Secondly, since developing countries are pushing (albeit painfully) utility companies to purchase renewable power from entrepreneur producers, it delivers the Grail of Net Zero Redundancy. We shall however refrain from being too naive about interconnection because NZE premises dumping power to the national grid when renewables produce too much while drawing power from the grid when renewables produce too little can't obviously fit for the national supply nor for the planet (cf the well known duck curve displaying the worldwide energy deficit on evenings from 5 to 10pm).

With sensible grid interconnection also comes Grail v.2.0 : In oversizing by 10% the harvesting infrastructure, hoteliers can offset over the years the grey energy of hotel construction (embodied energy of materials + construction + deconstruction), selling to the grid more electrons than purchased on lousy days).

Having your energy and eating it too… A decisive marketing advantage toward a growing customer base

It would be too long to cover the subject of sustainable tourism and of growing demand for Net Zero Emission accomodations.

In preliminary surveys and focus groups, many luxury guests are clearly curious of the experience, providing the claim is genuine, can be successfully documented and providing the technological breakthrough can be explained on-site. In that regard, it appears that requesting guests must be given the opportunity to visit and explore Carbon Neutrality, to take pictures and communicate about the synergy of technologies : thermal panels for hot water production, photovoltaic panels (doubling as shading for orchards, for promenade gardens or for parking lots), remotely placed wind turbines, battery room, PCM for energy storage layed inside tanks of cooling-water for AC, PCM inserted in walls, floor or ceiling of bedrooms.

Interestingly, most respondants declare to be willing to put a bit of skin into the game, for instance by allowing milder bedroom temperature at night, where the solar component vanishes .

Many respondants/guests are not interested, and given the choice, will always opt for a traditional hotel. The less interested guests are found among the elder segment, among males, and are more frequently encountered among Chinese, Taiwanese, Korean, Indian, Russian Mexicans, Middle East and central Europe nationals. Behavioural differences at hotel stays are also reflected in water consumption who varies in a ratio of 4 to 1 among countries !!!!

As marketers explain, a highly growing segment, mostly millennials but not only, mostly female but not only, mostly college+ educated but not only, mostly westerners, Japanese and other nationals but not only, is already targeting, through active searches of rankings, websites and blogs, the most responsible goods and services worldwide, including in the upscale segment. A growing segment of travellers is also getting concerned about the CO2e content of flights and about the energy mix of tourism destinations. For this rising public, wasting is not cool anymore ! Heavy Carbon Footprint is not a buzzword. Akin to the littering of plastic bags, to the poaching of endangered fauna or to the spilling of oil into the ocean, Heavy Carbon Footprint increasingly spells like an environmental wrongdoing.

1) Therefore, we can imagine what extreme surprise and delight a genuine zero footprint experience may offer to this discerning market! ! Energy on-site ! Self-generation ! Having your cake and eating it too !

2) It shall also grant tremendous goodwill and long term loyalty to the first hoteliers who, like the Tesla brand in automotive industry, explore the road less travelled.

3) Besides, a Net Zero hotel probably won’t need a large marketing budget past the first years. The environment conscious segment heavily correlates with early adopters and, as importantly, with active evangelists on internet (environment and tourism web sites & blogs, tripadvisor & reviews, facebook, twitter, instagram, pinterest, etc…). International awards and Top 100 rankings are within reach. Plus, main media and luxury media usually cover environmental breakthroughs for free…

4) Moreover, since Net Zero facilities are easier to achieve at larger scale (a threshold of 15 rooms is recommended), most guests lack the chance to build a zero footprint private house or to rent any. Assuming all other luxury perks get ticked high, assuming landscape & activities don't fail to match the proposition, the futuristic carbon neutral experience may prove as unique and memorable than staying at an ice hotel in Scandinavia, or than glamping under canvas. Impossible is a destination of its own ! Impossible is the ultimate frontier of luxury, marketers say...

5) Finally, in a new economy of sharing, where rental platforms are quickly eating our market share, including in luxury due to lack of distinctiveness versus private apartments & villas, at least Net Zero hoteliers can be ensured that their efforts won't be easily cannibalized ( Airbnb won’t eat our Net Zero lunch that soon…).

What about investment costs and operational break-even ?

The opportunity is just nascent. Cumulated cost of thermal & photovoltaic panels, wind turbines, inverters, high-cycles batteries and reliable PCMs would have been prohibitive as recently as in the early 2010s.

For developments happening in years 2017-2019 to come, land apart, depending on geographical conditions, we can assess an extra need of capital of 10%-15% for buildings with grid interconnection, or an extra need of capital of 15%-30% for building purely off-grid versus a conventional luxury boutique hotel of same comfort. Renewable energy investments will probably keep going down thanks to R& D and effect of scale.

Payback period is 6 to 15 years depending on geographic location and energy tariff. Payback period is therefore in the same magnitude than the hotel itself. After that time, the harvesting infrastructure actually increases hotel profits versus paying for energy.It is also likely that low interest Green Bonds flourish and become widely available to pioneering hoteliers from year 2020 till year 2030. Moreover the financial benefits from unique positionning, higher appeal and occupancy, higher guest loyalty, free publicity, minimal marketing & booking costs, and from steadier rates alone are expected to significantly shorten the payback period (down to 4-7 years ?). Lastly Payback period would also dramatically shortens if/when carbon taxes get levied on upscale buildings.

Now about real estate, acquiring or renting additional land for solar panels and wind turbines may cost +20% up to +35% compared with land requirements on small plots, or 0% when roofing is purposedly designed for solar panels. In the upscale segment, availability of large estate offering guests the luxury of strolling in gardens, green parks and orchards is common anyway, so the cost might as well be 0%. For new developments, taking the holistic option of a slightly remoter site where land is cheap and plenty, and surrounding landscape still untouched, is consistent to attract and retain nature loving/strolling guests.


The Net Zero Pledge. Let's accelerate the shift toward renewable energies. Let's decarbonize together the hospitality planet.

We have registered for the use of all the domain name . The content is similar to this web page, restating the above reasoning for Net Zero hotels in fossile fuel powered destinations and inviting interested parties to contact us until more people come onboard.

Similar to comments for this post, the coming web site is intended to become a maiden platform to discuss, dissiminate insights, experiments and early success from all interested stakeholders: architects, engineers, operators, developers, impact investors, civil society groups and media. In the meantime, please forward this post to persons who might benefit or contribute advice, with the aim of advocating Net Zero Emissions developments in the hundreds of destinations where they makes sense.


Experimental showcase of the Ocean Cave Pool Villas project, 60-65 keys (located between Tanjung Aan bay & Gerupuk village – South coast of Lombok Island – Indonesia)

The showcase resort under design and construction, the first of many expected independent hotels in the open Net Zero Pledge, applies all design principles explained above.

Energy for room comfort is for Air Conditioning and ventilation only. In tropical destinations, no heating is needed other than for hot water and this can be achieved by solar thermal panels offering 80% efficiency.

Criteria of super-insulation of bedrooms from outside, criteria of high airtightness, criteria of minimised surface of exchange with outside, criteria of high thermal inertia of building materials are all four matched together by a radical choice : as a personal choice of seed shareholders, most villas (not all) take the form of semi-subterranean caves dug within limestone hills (complemented by large roofed pool decks outdoors).

For this Net Zero showcase, we took this option seeking to achieve the "nearly passive building" requirement. However, readers shall understand that going the "cave way" is of course not compulsary to reach nearly passive building grade.

A 30m3 prototype has been dug in limestone in early 2013 to check the material resiliency. No fracture, ceiling crumbling or wall convergence has been measured along the course of the 4 years.

Lobby & Restaurants are positioned outdoor to the ocean breeze, with low consumption fans in back-up.

Renewable energy is planned to start from 6 000 m2 of photovoltaic panels, doubling as a (hopefully pleasant) 10 000 m2 organic orchard plus possibly from a couple of medium size wind turbines of 37.5 kVA each located 200m from the main hotel. It is ambitionned that by year 2025, the generation of renewable energy reach 2 000 kVA, supplying a couple of boutique hotels and restaurants through our peninsula microgrid.

The site is well documented by national meteorologists for strong solar irradiance along the year, including during the rainy season (only 500mm of rain yearly), for mild Southeast winds 9 months of the year, for strong West winds 3 months of the year.

Compressors are scheduled to operate during daytime and from photovoltaic energy only. They produce freezing of PCM for storage of energy in Air Conditioning water tank (as well as freezing of ice for the food storage room).

Storage of energy shall use 75-100 m3 of water tanks, plus the latent enthalpy of 35-50 m3 of biobased PCM, plus a limited amount of batteries (probably sized to release 100 kW only during 12 hours).

A second type of biobased PCM will be used to store hot water for guests, for laundry and for restaurant kitchens.

Back-up connection from the national grid has been be granted by authorities. Reselling of energy to the grid is presently in negotiation with high chances of being granted before the resort opening. However, for the "duck curve" ethics explained above, after a tuning estimated to 18 months, we insist to prove our "no-cheating NZE" achievement by operating almost 100% of the days from kWh produced and stored on site , when temptation would be uber-high to claim NZE like many, just by paying offsets or by constantly causing massive offloading/drawing on the national grid.

Land acquisition has been completed. Total land for the resort and its own energy generation is 60 000m2, 70% of it for the accomodation and leisure of guests and unrelated to the Net Zero endeavour.

Wilderness and extreme sports.

Along the course of the previous 9 years, we have acquired the surrounding peninsula of 100 hectare size, Turtle Reef Nature Sanctuary, earmarked by us to remain green at 80% , to protect it for further responsible boutique hotels, for small lounges & restaurants, and for outdoor activities on water and land. The nature sanctuary includes "Gerupuk Outside" the twin most famous surfing spots of Lombok island (to remain reachable to anyone), several botanical, bird & monkey watching parks, and the provision of 10 kilometers of hilly trails for trekking, horseback & mountain bike riding.

The nature sanctuary also include 50 000m2 of natural land doubling as a rough Pitch & Put. The longer-term plan aims at offering nature lovers and adrenaline junkies an unseen dodecathlon of other outdoor extreme sports on land, water and air (cliff climbing, via ferrata, Bmx downhill, E-bike cross, enduro, freestyle & trial, reef diving, surfski/kayak, kite surfing, foiler sailing catamarans, water strait crossings, zipping, cliff diving, paragliding).

Ocean Cave Pool Villas is targeted for opening by early 2022. Seed shareholders are two European individuals enjoying 11 and 15 years of experience in the ownership and top management of hotels and resorts. One of the 2 shareholders also passed in France all post-graduate exams related to paraseismic architecture and construction.

A Sketchup renderings illustrate below some views of the proof of concept.

Our proof of concept resort under design and construction, the first of many other expected hotels from other developers in the open Net Zero Pledge, is looking for external shareholders for 66% of its capital under an ambitious hybrid Climate Change Impact Investment venture (real estate + cleantech) called Earthccelerate aiming to reduce during years 2022-50 an amount of CO2e reaching 1 000 000 tons CO2e/year, 1/50 000th of global emissions.

Earthccelerate intends to convert to Net Zero Emission (NZE) & near-NZE, 30 000 rooms of 3rd parties' luxury hotels located in 9 largest fossil fuel powered countries of Asia Pacific (China, India, Indonesia, Malaysia, Thailand, Vietnam, Japan, Korea, Australia).

You may contact us if you would like to become a shareholder in this development. 50 units of one-bedroom-pool-villas and two-bedroom-pool-villas, to remain in hotel operations for about 40-48 weeks of the year during the first 15-20 years, are getting sold freehold as equity of the hospitality company (PMA) and of the Cleantech spinoff to a number of 30 - 50 individual impact investors.

We aim at a small group of inspiring persons of all ages. We foresee that this partnership will appear more fulfilling to pluri-aficionados of climate advocacy, cleantechs and disruptive technologies; of nature trekking, bird watching, scuba diving & horseback riding; of philantropy, music, art and social impact; of adrenaline sports such as climbing, surfing & fast sailing.

Overall budget of development, including ownership of freehold land, is around 45 MUSD (15MUSD of total budget being secured from seed investors). 

While the entity shall be regarded as an operating resort with restaurant, bar, fitness, meeting room, gardens, beach facilities, energy production & storage, company shares equivalent to the ownership of a double-bedroom pool villa will probably worth 850 KUSD, while shares entitling the ownership of a single-bedroom pool villa will probably worth 450 KUSD. Payments of shares will be done along years 2019-2022 to follow capital expenditures for the hotel development.


Please feel free to contact us if you feel inspired by the Net Zero hotel endeavour, by the cleantech activities and by the specifics of this small group of owners. We will mail you details of the development.
