The Fiction of Net Zero Offsets

Corporate climate pledges rely heavily on voluntary carbon markets. However, independent satellite data and ground-level audits show that the majority of forestry-based offsets represent no real reduction in atmospheric carbon.

Offset Efficacy Audit

A 2023 review of 50 major Verra-certified forestry projects showed systematic baseline exaggeration. The following data highlights the gap between claimed tons and actual sequestered tons.

Offset Type	Claimed Sequestered (Tons)	Audited Actual (Tons)	Efficacy Rate
Avoided Deforestation (REDD+)	10,000,000	600,000	6%
Reforestation	5,000,000	2,400,000	48%
Direct Air Capture (DAC)	100,000	98,000	98%

Estimated Net Tons Removed: 0.6 tons

JavaScript is disabled. Forestry offsets typically only yield between 6% and 48% net reduction due to leakage and baseline exaggeration. DAC yields ~98%. Multiply tons by these factors.

Common Mistakes in Carbon Accounting

Treating avoided emissions as equivalent to carbon removal.
Ignoring 'leakage'—where logging simply moves to an un-protected area.
Failing to account for forest fires releasing stored carbon.

FAQ: Carbon Markets

If offsets don't work, why do companies buy them?

They provide cheap, regulatory-compliant PR. Real emission reductions require expensive supply chain overhauls.

What is 'additionality'?

The proof that the carbon reduction would not have occurred without the offset funding. It is the most frequently faked metric.
