"Credit Disable Amount" is the amount of Carbon Emission Credits that have been either cancelled or retired through a "Credit Disable Transfer".
"Certificate Source" is a logical group that comprises of one or more "Credit Disable Transfers".
"Certificate" is a certification issued by TCO2 to you that proves that you own a proportion of a "Certificate Source".


TCO2 currently uses CERs as its Carbon Emission Credits.
CER or Certified Emission Reduction are units

  1. issued pursuant to Article 12 of the Kyoto Protocol.
  2. issued by the Clean Development Mechanism (CDM) Executive Board for emission reductions achieved by CDM projects and verified by a DOE under the rules of the International UNFCCC/Kyoto Protocol Rules.
  3. considered to be most reliable and can be used within the EU-ETS to comply with emission limitation targets.


All "Certificate Sources" and their inventory status alongside with the paper work and transaction logs of "Credit Disable Transfers" will be disclosed on this Site.
"Credit Disable Transfers" will take place BEFORE any "Certificates" are issued from a "Certificate Source", hence avoiding any possibility of issuing groundless certificates.
All "Certificates" issued from a particular "Certificate Source" will have a unique ID, amount, date and will be disclosed on this Site to provide maximum clarity and accountability, hence reducing the possibility of any double counting.
On issuing a new "Certificate" TCO2 will check the inventory for the requested "Certificate Source" so that the total amount of issued "Certificates" will not exceed the total "Credit Disable Amount" in that source.
If by some mistake ( such as an operational error or system error ) the total amount of "Certificates" have exceeded the total "Credit Disable Amount" in a "Credit Source", in order to balance the source, TCO2 will either add a "Credit Disable Transfer" or cancel some of the certificates issued.


When you purchase a "Certificate" it will mean that TCO2 will attribute a proportion of a particular "Certificate Source" to you.
All "Certificates" will have a unique ID, amount, issue date and will be a part of a "Certificate Source".
You may choose which "Certificate Source" you would like to generate your "Certificate" from, as long the amount you have requested is available from that source.
"Certificates" do not have an expiration date.
"Certificates" cannot be lent.
"Certificates" are non-transferable and their resale is prohibited.
"Certificates" cannot be redeemed for cash and have no cash value.


A "Certificate" can be cancelled.
A cancelled "Certificate" will not be counted as an issued "Certificate".
A "Certificate" cancellation will usually take place on events including, but not limited to order cancelation, operational mistakes or system errors.


From the nature of the service you understand and agree that,

  1. You must register as a member of this Site in order to own a "Certificate".
  2. You cannot own a "Certificate" without disclosing its information on this Site.
  3. All "Certificate" owners including you will be disclosed on this Site. However, you may choose to stay as an anonymous "Certificate" owner by setting your public settings to anonymous.
  4. If you own a "Certificate" and have decided to unregister with us, you waive all rights over the "Certificate" and the "Certificate" will hold its position with an anonymous user as its owner and will not be cancelled.

Further you agree that :

  1. TCO2 reserves the right to cancel any "Certificate" issued for any reason in its sole discretion.
  2. While TCO2 will exert its reasonable best efforts to maintain the validity and integrity of every "Certificate" and "Certificate Source" it will not guarantee that all procedures will be free of errors and that defects will be corrected.
  3. TCO2 is not responsible for any lost, stolen or misused "Certificate".

If you do not agree to all of these terms do not purchase any "Certificate" from us.


You agree that TCO2 may terminate this Site, these Terms, your license, limit your access to all or any part of this Site at any time with or without cause, with or without notification and for any reason in its sole discretion.
