Our climate projects
Greentripper works only with climate projects certified by the highest standards (Gold Standard). Supporting our climate projects is giving back to nature all the pleasure it gives you.
Frequently asked questions
Why should I offset my trip?
Unfortunately nearly every form of transport emits CO2. At this time, CO2 offsetting is the only way to neutralize the climate impact of your trip.

Offset means that you pay to reduce carbon dioxide in the atmosphere with the same quantity that the quantity produced by you activity. In this way, you can neutralize CO2. This is a voluntary way to do something about your CO2 emissions & climate impact. There is no obligation but every little contribution helps. The climate change issue can only be solved if we all contribute now. CO2 offsetting allows you to limit concretely your impact and not only to help you to sleep at night. The aviation sector is responsible for 2 to 3 % of worldwide CO2 emissions and the CO2 offsetting is the only way to limit the climate impact of your trips.
There are many climate projects that need your help. We make sure the climate projects proposed respond to high quality standards so you are sure your contribution is going to make a change.
Why offset with Greentripper?
  • CO2 offsetting via Greentripper is credible, fast, easy !
  • Greentripper only supports independently certified climate projects; we guarantee you that your investment goes to the right place and makes a real contribution to addressing urgent global climate change issues.
  • Greentripper is a CO2logic initiative, a reliable and trustworthy organisation with more than 10 years experience in climate advisory & climate project developments. Greentripper and CO2logic are verified by multiple organizations – including by Forum Ethibel and Vinçotte.
  • You offset your CO2 emissions by investing in sustainable climate projects in developing countries, which improves the living conditions of the people there.
How does the CO2 compensation work?
  1. You compensate by making a financial contribution for a CO2 reduction project in a developing countries.
  2. With your contribution, there will be made a CO2 reduction in this project equal to the CO2 emitted by your travel.
This reduction wouldn’t happen without your support.

By offsetting your trip’s CO2 emissions, you give households in developing countries access to energy efficient solutions, renewable energies & most importantly a better future through low carbon socio-economic & sustainable development. A win for our globally shared climate and a win for the local people.

Greentripper calculates, for example, how many solar panel in Africa are required generate electricity in order to neutralize the emissions from your trip. The operation of the solar panels enables to avoid CO2 emissions that would not happen without your contribution. This improved situation is controlled and certified to guarantee to make sure that you have made a change in favour of our climate.
This short film shows you how CO2 offsetting works.

What is a ton of CO2?
A plane (or whatever your mean of transport) uses energy to get where it’s going. This energy comes from burning fossil fuels, which releases CO2, which contributes to climate disruption. To give you an idea, 1 ton of CO2 is emitted by:
  • 5.556 km with your car in Belgium
  • 1.000 showers
  • 336 classic meals
  • watching TV for 24.000 (1000 days)
One ton CO2 could be represented by 1/5 of an Atomium ball or by an air balloon of 200m3!

What represents 1 ton CO2 in the climate projects Greentripper supports?
With the Greentripper calculator, you calculate the CO2 emissions of your trip, you compensate and you support sustainable climate projects, which will reduce the CO2 emissions.

With the compensation of 1 ton CO2, you invest in:
  • 1 waterfilter for 1 family of 4 to 5 persons for a period of 9 months. Thanks to the waterfilters, families will use less wood to boil water in order to have drinkable water. The LifeStraw Family water filters will be replaced and disposed of every three years.
    The LifeStraw® Family is a point-of-use microbial water treatment system intended for routine use in low-income settings. The system can filter up to 18,000 liters of water, enough to supply a family of five with microbiologically clean drinking water for three years. These units will treat contaminated drinking water, and reduce the demand for conventional water treatment through boiling water with non-renewable biomass. With the assistance of carbon finance, this project can be economically sustainable and provide a significant improvement in public health.
  • Two efficient cookstoves allowing one family to cook during 4 months with these artisanal stoves. (in Ouganda)
How much does it cost?
The further you travel, the more CO2 you emit, so the cost depends on your destination.

Simulate the carbon footprint of your trip on our calculator and see how accessible climate protection is. Compare your travel budget with your climate contribution… it is usually much less than 5%.
For the offset of my air travel, why is there a difference between the CO2 impact of Business, First and Economy Class seats?
First Class & Business Class seats take up more space, which means that fewer passengers can fit in the same airplane. Therefore, more CO2 is attributed to First Class & Business Class passengers than to those from one in Economy Class.

It is comparable to a car transporting 1 or 4 people. Although 4 people will be heavier to transport, there is a scaling effect, so the more passengers, the lower the emissions per person!
For the offset of my air travel, why compensate the emissions taking into account the radiative forcing impact?
If we want to calculate the full impact of air travel, we take into account the CO2 emissions but also other factors like contrails, the white could stripes left behind planes. They have an additional greenhouse effect. Independent science (Bilan Carbone, ADEME) estimates thal RF of aviation is 2 times that of just CO2 emissions from burning kerosene.

The Carbon Neutral Company says :
“A review of currently available information on the impacts of aviation on the global climate system shows clearly that these extend beyond the single effect of carbon dioxide emissions and that all the additional factors combined amount to an added warming effect. … Allowing for all the different metrics developed for aircraft impacts, it is suggested that a factor of approximately two should be applied to the carbon cost of flight to account for the overall impact of aviation.”
What projects does GREENTRIPPER support?
Can I trust the Greentripper projects?
Greentripper’s projects are independently & externally verified and certified to meet the most stringent requirements. Verification of the projects is done by Forum Ethibel, an independent and internationally recognised organisation that is designated and checked by Gold Standard (developed by WWF) or the UN. We are also controlled by Vinçotte. These agencies verify whether a project has been set up according to the criteria and whether it continues to meet them. It is guaranteed that these projects reduce CO2emissions and really contribute to better living conditions for local people in. A win for the environment and a win for the local people.
Can I trust Greentripper to offset my impact?
Greentripper and CO2logic are verified by multiple organizations – including by Forum Ethibel and Vinçotte – and only works with certified climate projects. Greentripper can therefore guarantee that the offsetting really takes place. The project is reviewed annually to see ensure that its impact on climate change is actually being achieved. In this certified system, climate credits are issued per tonne of CO2 that is actually reduced. These credits are placed in a register and removed when they are sold. In this way, it is ensured that the credits can only be sold once.

Monitoring the projects
To ensure the CO2 is actually offset, it’s important to measure how much CO2 emissions are avoided by the project. Without measurements, monitoring & control, you would be supporting a nice project without knowing whether the CO2 from your trip has really been offset. So all Greentripper projects are checked by qualified independent organisations. As an organisation we are also closely monitored by Forum Ethibel to ensure that your CO2 is fully offset.

We guarantee that the amount of CO2 you choose to offset will be matched by an actual decrease in CO2 equivalents. When a project has been inspected it receives a seal of approval, and every ton of CO2 saved is numbered and traceable. This is called a CO2 credit. Each credit represents a verified 1000 kilo of 1 ton reduction in CO2 equivalents. The credits are called Verified Emission Reductions (VERs). Monitoring is done by independent internationally-recognised offset auditors, such as DNV, TÜV or SGS. The auditors are nominated and inspected by Gold Standard or the UNFCCC. These auditing bureaus check whether a project is set up and operates according to a particular set of rules. Such a set of rules is known as a ‘standard.’ We only work with projects that use the most stringent international standards such as Gold Standard or equivalent.

Our climate projects give households access to more sustainable energies in areas that really need it. Our projects allow important CO2 reductions accompanied by sustainable development & improved living conditions for the local population. The developed or selected projects also contribute in achieving many of the Sustainable Development Goals (SDGs). Your contribution makes this possible!

Why doesn’t Greentripper support specific forestry projects?
Reforestation allows a temporary storage of CO2 emissions. When trees are cut down (and burnt somewhere down the life cycle), the CO2 is released back into the atmosphere. This is unfortunately not a permanent CO2 reduction, unlike our other climate projects.
Planting trees usually allows to store CO2 emissions over a period of 20 to 80 years, that’s not enough. We want to offer real sustainable solutions! The climate projects we support will result in a permanent decrease of CO2 emissions, structural changes and combat desertification, deforestation and forest degradation. It is important to prevent the problem rather than trying to fix it. Ideally we should do both, but let’s start with preventing the problem.
Thanks to facilitation of waterfilters and efficient woodstove, in Uganda, Benin, Kenya, RDC and a few other African countries, local populations receive access to more sustainable energy and better life conditions. It is better for climate, for local sustainable socio-economic development and for health. Our climate projects are also developed in line with the Sustainable Development Goals (SDGs).

Why choose the Greentripper calculator ?
Greentripper is based on the Bilan Carbone® method from ADEME - the French Environment and Energy Management Agency. ADEME is recognized globally for its method of the calculation of greenhouse gas emission (Bilan Carbone method). The agency is a pioneer for the calculation of the greenhouse gas emissions and for the conversion in CO2 equivalents depending on the global warming potential (GWP), the contribution of each gas to the greenhouse effect.
The teams of CO2logic and Greentripper can accurately calculate the carbon footprint of your activities and of your travels but this requires lots of information and data. To make it accessible we decided to work with averages defined by ADEME and generally approved by the sector.
The Greentripper calculator offers several choices:
  • You can choose to offset with or without radiative forcing ? The radiative forcing (RF) caused by the contrails. (white lines we see behind the plane during its flight). These contrails have an additional greenhouse effect. Independent scientists (from the ADEME and other scientific institutions) say the RF is equivalent to 2 times the impact of the CO2 emissions created by combusting kerosene.
  • You want to know how and where your money will be used to reduce your tons of CO2 emissions ? You have the choice between several CO2 reduction projects. Once offset, you will receive a certificate mentioning the amount of CO2 (in tons) which will be effectively reduced thanks to you in your selected project.
  • You want to offset your flight in 2 minutes? It is possible, you can fill in the first step and then directly move on to the last step where you will pay your compensation.

Why does Greentripper support climate projects in developing countries?
We share ONE atmosphere!

Whether you emit one ton of CO2 in the US, in Europe, in Africa or Asia, it is the same for our climate. But with the same amount of money we can reduce much more CO2 in developing countries. Many people travel all over the world and so it makes sense to support projects outside where people need it most. Our developed countries are responsible for climate disruption while developing (poorer) countries will suffer the most. Their population is booming (especially in Africa & Asia) so let’s help developing countries in the switch to a low carbon development. “In a global economy we have a global responsibility” CO2logic.

How much does an airplane emit?
According to Bilan Carbone of ADEME:
  • 0,11 tot 0,13 kg CO2 per km per passenger in Economy Class
  • 0,25 tot 0,26kg CO2 per km per passenger in Business Class
  • 0,39 kg CO2 per km per passenger in First Class (only for long haul flight).
If we take into account the radiative forcing, the emissions are at least multiplied by the factor 2. .
Why does a short haul flight emit relatively more CO2 than a long haul flight?
A plane burns a lot of fuel taking off (and landing). When it is in the air it uses much less per km or mile.
Therefore, short flights or indirect flights with stopovers are extra polluting per km. That means that for long flights, the average emissions are less per km.
How to travel as green as possible?
Choose the means of transport that emits the least in getting to your destination. For example, a bus to Austria from the Belgium emits approximately 6 times less than a plane. The remaining emissions can be offset with Greentripper
You can become a more responsible traveller through a few simple steps:
  1. Calculate & Offset your trip’s CO2 emissions with certified climate projects (link calculator)
  2. Use organic & biodegradable (soap, suntan creme, washing powder, …) as these end up in waterways & destroy ecosystem, corals,…
  3. Don’t throw your waste into the wild, pick up litter you find on your way and drop it into the closest bin. Remember that any waste (plastic bags, cans,…) can cause death to local species (birds, fish, turtles,…)
  4. If you are a smoker take a pocket ashtray with you as cigarette filters pollute waterways and take a very long time to decompose.
  5. Don’t feed animals or touch animals, unless correctly informed, as it might seriously alter/harm their diet.
  6. Don’t pick up any flowers as many are close to extinction.
  7. Choose for green labelled hotels/hosts, which clearly care about preserving the environment and local resources.
  8. If you dive, don’t touch or step on anything. You might damage what you came for…
  9. Eat plant-based, but if you eat meat as for organic and/or local meat
  10. For your souvenir gifts, choose local artisans
  11. Don’t waste water, in most countries it has become a scarce resource
  12. If you stay at the same hotel for a while, ask not to change the towels unless necessary.
  13. In many countries the use of electricity has a high impact on climate change or is a scarcity. Turn off the light & electrical appliances and avoid the use of air-conditioning.
You’re a company and you would like to limit the impact of your employees?
  1. Use teleconferencing and/or videoconferencing instead of systematically air traveling. It is better for the environment and for your income.
  2. Promote the means of transport with the lowest impact. Taking the plane to travel from Brussel to London is not necessarily the best option...
  3. Inform your employees about the greenhouse gas emissions linked to their transport: not only for the business travels but also for the daily transport: impact of the company car, ...
  4. Reward the best employees who has the lowest CO2 impact.
  5. Finance projects thanks to CO2 compensation programmes.
  6. For the business travels, choose hotels who care about environment!
Are your CO2 emissions offset with the EU ETS system?
No, not with Greentripper ! The EU ETS system has given free emission credits to heavy CO2 emitting industries equivalent to their CO2 cap. If they emit more they have to buy CO2 credits from the ETS. For the aviation sector it puts a tax on some of the CO2 emissions from flights within Europe. This tax is not used to offset. Your flight continues to emit CO2 and other greenhouse gases. So if you want to neutralize your emissions, it can be done by offsetting these through Greentripper climate projects.
