  1. 1.
    CO2 allowances - Carbon allowance is a term used for a certificate or permit that represents the legal right to emit one tonne of carbon dioxide or equivalent greenhouse gas. Controlled and issued by governments.
  2. 2.
    Surrender/Cancel/Use - Using CO2 allowances or renewable energy certificates to cover CO2 emissions. After the use the certificate is attached to a specific entity consumption and can’t be revoked.
  3. 3.
    Offsetting CO2 allowances - Meaning to cover CO2 footprint using CO2 allowances.
  4. 4.
    Offsetting - Meaning to cover CO2 footprint using CO2 allowances or canceling renewable energy certificates.

Carbon Offsets And Renewable Energy Certificates

Many organisations and businesses manage their greenhouse gas (GHG) footprint by developing strategies for emissions inventory. Different strategies produce different scopes. These scopes help distinguish emissions from directly owned sources by the business from consequential activities made by those businesses or organisations but produced by different sources. While different scopes through pinpointing sources distinguish their emission accounts, different measures by the government to reduce the GHG are applied. Thus, emerge two financial tools - carbon offsets and RECs to manage an overall carbon footprint in the economy.
The Paris Agreement negotiated the 196 parties within the United Nations Framework Convention on Climate Change (UNFCCC) to steer their national energy politics towards optimal reduction in overall carbon footprint. By appealing to local governmental bodies the goals were set to incline towards a more renewable energy consumption by regulating it via the more popular options of carbon offsets and renewable energy certificates (GOs for EU and RECs globally). Each nation still holds an autonomous decision making base towards picking and reaching a better solution for set goals.
If the goal is to remove CO2 emissions or provide a support to emission reducing activities, a carbon offset is the choice in question. Also, offsets lower costs of overall GHG emission mitigation. Whereas RECs mainly support renewable energy development, as well as expand the overall choice in consumer’s electricity sources. While REC holders claim a 1 MWh use of renewable energy from certainly ‘green’ sources of electricity, offset owners mainly claim a reduced amount of GHG emissions outside their organisation’s operations.
Now, most of the market inside private ventures oftenly choose carbon offsets, but even this type of choice usually warrants a mandatory governmental overwatch in the form of carbon or CO2 allowances (CO2 allowances - a term that shall be used in this WP to define carbon allowances as a whole to avoid any confusion between the terms carbon offset and carbon allowance). In the case of the EU, the mandated form of carbon allowance or CO2 allowance is the so-called European Union Allowance (EUA). For further information, on how different markets around the globe choose what particular form of mandated certification system, see the ‘Market’ section inside this white paper.

Why Enrex Chooses Only Government Mandated Certificates?

  • Only government mandated certificates can make a real impact for going CO2 neutral, and the crypto community is ready for it.
  • Government issued certificates are tracked and have strong governance and they are hard to manipulate.

What will happen, if the certificates rise in the regulated market?

The more the price will rise, the more renewable technologies will evolve and CO2 emissions will be reduced.
