What is a carbon offset?

Offsets have been criticized throughout their history

The basic idea behind carbon offsets

1. Cut emissions, use high quality offsets, and regularly revised offsetting strategy as best practice evolves

2. Shift to carbon removal offsetting

3. Shift to long-lived storage

4. Support the development of net zero aligned offsetting

Andrea Bonzanni, IETA: “There are different views on where the market will head to, and this is normal...The Glasgow deal “is a starting point for the private sector to keep delivering high-quality credits and functioning market.”

Andrea Bonzanni, IETA’s international policy director, believes it will still be possible for a company to issue credits claiming emission cuts without authorization.

Henrik Hasselknippe: “Markets can handle multiple standards...That’s something that we see in many markets.”

Lambert Schneider, research coordinator on international carbon policy at the Oeko-Institut: “The voluntary market is really booming, but at the same time you have this integrity problem.” Although the COP26 agreement doesn’t directly affect voluntary markets, its rules may “spill over into the system, setting the bar higher.”

Ocean Sequestration and Carbon Offset

Offsets should be additional

Offsets should be permanent

Offsets should not have unintentional consequences

Poorer countries could benefit financially from more transparent offset trading.

The first offset goes back to AES in 1989

Verifying offsets ensures that the reduction or removal actually takes place

Why does it matter that "carbon" is a policy commodity?

Why not all offsets are created equal?
