Cut Off Wasteful Offsets
Forests are the largest carbon sink and most effective sequestration mechanism on land - 59.7 billion metric tons (BMT) of carbon were stored in US Forests in 2022, and a large proportion of offset projects focus on forests. Forest offsets can cover three types of activity: 1) avoided conversion, whereby a forest that is threatened is protected (“proforestation”); 2) afforestation or reforestation, whereby a degraded or cut forest is restored and protected; and 3) improved forest management (IFM) which can include logging, thinning, and other harmful forestry practices that emit tons of CO2e back into the atmosphere and often decimates the forest.
The vast majority of offsets go to allegedly improved forest management (IFM) emitting more CO2e than would happen without these management activities creating management commodification which can add a layer of profit to harmful forestry practices. In California, for example, only 4% of forest offsets were dedicated to avoided conversion.
Preserving forests is a key building block of any climate preservation program. It is the single most effective way to sequester CO2e and support biodiversity. It is proforestation - the permanent protection of forests without any management - which has the highest carbon sequestration potential. (Please refer to the "No management" graphic on the home page and below.)
Stephenson et al (2014) in their study: "Rate of tree carbon accumulation increases continuously with tree size" analyzed 403 tropical and temperate tree species to prove that mass growth rate increases continuously with tree size for most species. In other words, the largest and oldest species fix the largest amounts of carbon compared to smaller trees. In fact, a single big tree can add the same amount of carbon to the forest within a year as is contained in an entire mid-sized tree.
Even though it may appear that smaller trees are adding mass faster ("grow faster"), bigger trees do since they have a larger surface and leaf area - it;s simply not as obvious because the addition is spread around the entire circumference of a tree. This dispels the myth that forests need to be managed to sequester more carbon, and also that tree plantations are just as good as old forest ecosystems.
In addition to financing polluting forest management practices, offsets are fundamentally flawed due to their lack of reliability and enforceability. Proponents of carbon offsets admit that to have integrity, the emission reductions or sequestration in forests sold as offsets need to show (1) permanence; (2) cannot merely be transferred elsewhere (“no leakage”); (3) beyond what would otherwise occur without payment of the carbon fee (“additionality”); and, (4) subject to verification and enforcement (verifiable). What these same proponents fail to acknowledge is that these integrity building blocks cannot be met. Specifically, forest offsets suffer from (1) increasing threats from drought, fire, storms, and management making it impossible to guarantee permanence; (2) using offsets for logging or thinning (IFM) under the guise of “restoring forest health” thereby reemitting CO2 into the atmosphere undermining the benefit of the offset; (3) proving additionality which is subject to misrepresentations and exaggeration; and (4) verification which often happens through unreliable third parties far away.
For example, The Nature Conservancy repeatedly claims that already protected lands are in danger of logging and sells offsets to polluters who then claim that they had lowered emissions, creating a false accounting of progress. Worse, the forested lands covered by offsets often become working forests where selective cutting (of the largest and most valuable trees first), thinning, burning, etc. continues. In short, even “avoided conversion” offsets have been found unreliable.
Offset programs have led to profits for carbon traders and verifiers but have not resulted in the urgently needed forest protections or CO2e reductions. Instead of offsets, Keep It In The Forest advocates for the adoption of a polluter-pays (per ton of CO2e emitted) system that funds programs that permanently protect forests. A polluter pays approach has many benefits, including to public health, and is consistent with maintaining full employment and a vibrant economy. Funds collected from pollution fees can create, expand, and connect strategic forest reserves needed to balance extreme weather, provide water security, and stem biodiversity losses. This approach has the potential to carry us towards the goals of protecting 30% of the lands and waters from conversion or extraction by 2030, and ideally, 50% by 2050.
Let’s stop wasting funds on offsets and, instead, keep the trees in the forests and protect them so they can provide the ecosystem services all Americans need.
