Frequently Asked Questions

CO2 compensation: what is CO2 neutral or carbon neutral?

‘CO2 neutral’ or ‘carbon neutral’ means that CO2 emission caused by the use of energy generated by fossil fuels is being compensated by

  • Removing CO2 out of the atmosphere
  • Reducing CO2 emission by using sustainable and renewable energy

CO2 is taken out of the atmosphere by plants and trees that grow and store the CO2 in their tissue in the form of carbon. A tree is actually a huge storage facility of carbon. In addition, trees also give us oxygen (O2) as a 'by-product' of this storage process. By planting sufficient numbers of new trees the extra emission of CO2 can be compensated for. CO2 emission can also be prevented - by using sustainable energy. There is no emission of greenhouse gasses involved in the production of energy generated by wind, water or sunlight.

How is the CO2 being offset?

Cleanbits realizes CO2 neutrality in two ways:

  1. By means of CO2 offset through tree plantations.
  2. By means of CO2 emission reduction through renewable energy (green certificates).

Cleanbits equally invests in both options, providing customers a choice of action.

Is the CO2 reduction in emissions being officially audited? How can I be sure of the credibility of the CO2 neutralization program?

Together with the Geldersch Landschap Charity, Cleanbits enables CO2 compensation through tree plantation in several ‘internet forests’ in Holland. The Dutch government ensures that these trees remain intact for a minimum of 99 years, yet the planning is 250 years. It is a public and environmentally friendly location which is open for everyone. Similarly, Cleanbits is also working with WindUnie to ensure the carbon emissions are neutralized through investment in renewable energy rights. Certificates or a mix thereof are based on an international system of certifcation: Verified Emission Reductions (VER's), Certified Emission Reductions (CER's), Emission Reduction Units (ERU's) and European Allowances (EUA's).

Which part of CO2 emission as a result of internet use will be compensated for by Cleanbits?

Cleanbits compensates the CO2 emission that is caused by the power consumption of web servers, racks and data centers. Hence, Cleanbits does not compensate for the carbon emission that is caused by using your computer and surfing on the internet or as a consequence of the manufacturing of the digital equipment.

How does Cleanbits calculate the energy consumption of my individual web site?

It is not possible to calculate the exact energy consumption (hence, CO2 emission) of every single website. This data is simply not traceable at the data centers. So in order to be as accurate as possible, Cleanbits has executed an exhaustive estimation in order to define the average electricity consumption of a web site. This is based on a hundred thousand domain statistics from a number of datacenters including for example the energy use of email traffic, network equipment, emergency generators and cooling systems. This together with the average traffic to your site should give an indication ‘advise’ of your sites energy use and hence CO2 emission. This is merely an average indication and does not suffice to be 100% accurate for each and every website.

How does Cleanbits calculate the energy of my servers, racks and data centers?

Cleanbits has executed an exhaustive estimation based on industry standards to define the average electricity consumption of a web server, racks and data centers. This is based on average amp per server, network equipment, emergency generators and cooling systems. This provides an average electricity usage indication per server.

Does Cleanbits only compensate for CO2 emission or also for other greenhouse gases?

Besides CO2, the combustion of fossil fuels also results in the emission of other greenhouse gases. Cleanbits compensates for these emissions as well. The quantity of these gases is not mentioned separately by Cleanbits, but it is expressed in CO2 equivalents.

My website is running on green but is not registered in your database?

We aim to keep our database continually up to date. It is not always possible to track multiple shared hosting or larger data centers. So any additional information you can provide us with is welcome. Please contact us.

How do I contribute?

You can pay for your CO2 compensation in several ways. Through iDeal, via Paypal, or by credit card. All Cleanbits’ financial traffic is being handled by MijnWinkel.

How do I end my contribution?

Any Cleanbits contribution runs for the period of one full year. For every new year you will receive an automatic renewal invoice. Termination of a contribution contract during the course of the year is not possible.

How does the Cleanbits counter work (top right of the banner)?

The Counter shows how much CO2 has been compensated or saved by all Cleanbits customers together at that moment in time, whether through tree compensation, or through renewable energy. It is a dynamic counter, so if you are contributing for a year, the CO2 compensation or savings per hour will be dynamically added to the total amount. And the counter will run a little faster for every new client added. This counter gives transperency in a greener internet.

Instead of compensating I would rather step over to a green hosting provider. How can Cleanbits help?

Cleanbits does not offer hosting facilities but has a comprehensive list of green hosting providers that you can step over to. It is our aim to help you in this mission. Or Contact us for further information.

How and when do I use the Cleanbits logo on my site?

If your website or server is registered as carbon neutral please use our logo to make this claim on your website. By placing the Cleanbits logo on your website, participants state their digital activities are CO2 neutral, while at the same time they express their support for making the world wide web a more environmentally friendly place.

All our logo's can be found on the logo page.
