Carbon Basics

​
What is a carbon offset?
A Carbon offset is a market based incentive to fix the environment. An offset typically represents one equivalent tonne of CO2 removed from the atmosphere by a green project (e.g. reforesting an area of land). Projects can issue certificates verified by an independent board, provided they meet a certain set of criteria. Individuals or corporations can then purchase a carbon offset, in order to reduce their carbon footprint.
How effective is carbon offsetting?
Carbon offsetting is effective as long as the offsets are ‘additional’, meaning that they would not have occurred in the absence of an offset market. They must also be permanent, e.g. a tree planted as an offset must not be cut down. Changeblock ensures that every offset listed on our platform meets this criteria.
What is a carbon footprint?
Your carbon footprint is the total amount of greenhouse gasses that are generated by our individual actions. Nearly everything we do including watching the TV, purchasing groceries and using the car produces CO2 as a byproduct.
How do you calculate my carbon footprint?
Changeblock submits the answers to questions about your lifestyle through our algorithm. The algorithm is able to determine the closest estimate for your footprint and is trained using the average GHG usage of UK households. ‍ Calculate yours now.​
How do you ensure the quality of offsetting projects admitted onto your platform?
Changeblock employs a stringent vetting process for all carbon offset projects admitted onto our platform, offsets can only be admitted if they are additional and permanent.
What are Voluntary Carbon Markets?
The voluntary carbon markets function outside of compliance markets and enable companies and individuals to purchase carbon offsets on a voluntary basis with no intended use for compliance purposes. In short, this is a market that exists to allow companies, individuals and institutions to help the environment through carbon offsetting of their own free will, without being compelled to through legal means.
