Offsetting is a bit like quitting smoking by paying someone to bake a cake. It cannot be compared with like.

Planting a tree that may or may not grow, has an indeterminate lifespan, and can be a victim of drought, flood, or blight does not “offset” the use of fossil carbon that is stably stored in the geosphere.
Baking a cake may be a good thing in itself, but it’s unlikely to help you quit smoking. Likewise, planting trees will not compensate for the real, long-term impact of the carbon emissions now being released into a saturated atmosphere.
The problem is that offsetting in its current form simply does not do what the name suggests. Due to the mix of scientific and practical problems, offsetting often doesn’t work at all and can even make the problem worse.
The theory is that through offsets, organizations, events or individuals effectively “eliminate” or “offset” the emissions from their ongoing activities, whether from transportation, building stadiums or powering facilities.
Following this logic, organizations can purchase additional offsets to reduce their “overall” impact, and thus can claim an absolute reduction in their emissions and environmental impact, when in reality, they have made no contribution to their habits, behaviour, operations, purchases Any alignment process or organizational structure.
pillar
However, this theory quickly collapsed in the face of the climate crisis.
According to the latest climate models produced by the Intergovernmental Panel on Climate Change (IPCC), limiting global warming to 1.5°C would require global emissions to peak by 2025 and fall by 43% by 2030, reaching a net zero emission.
According to the IPCC, to meet these temperature goals, global emissions would need to drop by around 90%, and would rely on various types of carbon removal to do so Another 10% that only needs to be cut.
It is fundamentally unscientific to rely on carbon offsets instead of pursuing emission reductions at source. However, it also has big problems on several other levels.
Offsetting has become a central pillar of corporate sustainability strategies, net-zero emissions commitments and governments’ climate policy plans.

Household names such as EasyJet, Heathrow Airport, BP and Shell all rely heavily on offsetting schemes to ‘offset’ their operational emissions, look green and claim to be carbon neutral.
Implicitly, they are heavily relied upon in national climate plans and are used sporadically by consumers to appease the conscience, for example, on long-haul flights.
Carbon offsetting is big business, and the size of the global market is bound to swell as more organizations seek to be carbon neutral.
According to analysts, the demand for carbon offsets will increase by 15 times By 2030 or more, up to 100 times by 2050.
By 2050, the value of the global carbon market could increase to $200 billion. There are concerns that demand for compensation will outstrip supply as early as 2024, and new monoculture forests will put enormous pressure on land, communities and wildlife.
popular
In addition, through offset projects and a common but controversial method of bookkeeping emissions (known as “market-based accounting”), organizations can claim substantial reductions in global warming emissions without changing their operations, partnerships or governance.
To illustrate the point, look no further than Cisco Systems, one of the largest technology conglomerates in the world with nearly 80,000 employees.
In 2021, Cisco boasted that they had reduced Scope 1 and Scope 2 pollution (emissions that the company “owns” or “controls”) by 60% over the past 15 years.
But when those claims are assessed through a different accounting method, excluding offsets and renewable credits purchased by Cisco, the situation is quite different: Emissions increased by 22%.
Many offset mechanisms are popular and will dominate the global carbon offset market in the coming years.
transfer
These include nature-based offsetting – a category that uses plants, trees, forests, soil or oceans to remove carbon from the atmosphere and store it.
Depending on the offsetting project in question, this approach could theoretically also protect and conserve ecosystems considered carbon sinks, such as rainforests and peat swamps, with rewilding programmes. In 2019, nature-based offsets accounted for more than half (56.4%) voluntary offset market.
Then there are renewable energy offsets, which aim to maintain or increase renewable energy generation, eventually displacing the use of fossil fuels and thereby preventing carbon emissions in the first place. 2019 Renewable Energy Projects 21.3% of the voluntary offset market.
Cash is being earned – but huge questions remain about their trustworthiness, transparency and integrity.
Even some traditionally cautious organizations are skeptical that offsets will work.This International Energy Agency (IEA) In 2021, it said that “there may be a limited supply of emissions credits eligible for global net-zero emissions, and the use of such credits may divert investment away from options that would directly reduce emissions.”
Six ways offsetting lands us in climate prison
- Offset doesn’t work
Current scientific evidence suggests that offsets have not lived up to their promises. A study by the European Commission It was found that 85% of offsetting projects under the UN’s Clean Development Mechanism (CDM) failed to actually reduce emissions, and that only 2% were likely to do so. Some large corporate offset programs have been undermined by the very climate impacts they were supposed to offset. In 2021, as record-breaking wildfires ravaged the US states of California, Oregon and Washington, Forest offsets bought by Microsoft and fossil fuel giant BP destroyed These incidents are not uncommon.Since 2015, California wildfires have Damaged Six Forest Offset Buffer Projects, putting between 5.7 million and 6.8 million tons of carbon back into the atmosphere, according to CarbonPlan.
- Plans can cause real harm
Offset projects can be detrimental both in terms of outright failure and the project’s impact on local communities, economies and the natural world.There are multiple examples of implementing nature-based offset programs regardless of legal or Indigenous people’s customary land use rights. These low quality and shoddy offset programs have indicated that it would lead to human rights violationsadverse impacts on biodiversity, and unlikely to offer a long-term store carbon emissions. a common example When native forests, rich in biodiversity, are cleared to make way for fast-growing eucalyptus plantations, monocultures are formed, devoid of wildlife, which can drain groundwater from local communities and disrupt agriculture.
- offset is a form carbon wash
Trying to offset the burning of stable fossil carbon stores by planting volatile stores like trees, which faces multiple threats in our warming world, is not like an exchange of like.Scientists believe this will require close One ton of carbon dioxide emitted for half a million years Released today by burning fossil fuels, it is naturally removed from the atmosphere. This harsh scientific truth goes to the heart of the offset dilemma: To effectively eliminate emissions, offset mechanisms must remain in place for hundreds of thousands of years. However, the average contract period for tree offset programs is approximately 40 years.
- system can play
Through accounting tricks and an unclear carbon market, offsets can be massively misallocated, often meaning no reduction in total emissions. It’s hard to justify that no renewable energy project would ever be built anyway.Research at Berkeley, Oxford and the Carbon Project Discover Offsets of up to 85% Off Sale Today Not Extrasmeaning is Selling these credits has no effect on reducing emissions.
- It offers an excuse for ‘pollution as always’
Offsetting can justify and legitimize the status quo, allowing organizations to continue to pollute while claiming leadership and making progress on sustainability and environmental issues. Relying on offsets allowed one company, Cisco Systems mentioned above, to claim a 60% reduction in emissions, when their actual emissions rose by 22%. By analyzing carbon credits allocated to 1,350 wind farms in India, researchers find at least 52% approved Carbon credits are allocated to projects that would have been built anywayThe researchers concluded, “In addition to wasting scarce resources, we estimate that selling these offsets to regulate polluters also substantially increases global carbon dioxide emissions.”
- Offsets prevent real change
The cost and apparent convenience of offsetting means that the more challenging structural decisions needed to address an organization’s climate impact may be delayed. As a method, offsets are flawed temporary fixes that by default become the primary response to problems. Especially when it comes to rich people, whether countries, corporations or individuals, why change if you can spend money to avoid actually changing behavior? Thinking they are realistic options for more systemic change when they are not limits our thinking, creativity and ambition to find real ways to thrive in a limited biosphere.
out of prison?
It is clear that offsetting cannot break the bonds of carbon pollution that currently lock humans and the rest of the natural world into the brutal turmoil of a warming world.
In the race to decarbonize the global economy, if there is room for offsets, however small, they need to meet certain basic criteria.
The method for each offset project to escape the global heating prison must be:
1. A true complement to other mitigation efforts – for example, carbon reductions would not have been achieved without the program.
2. Permanence – Carbon must be permanently stored to have “offset” status – as opposed to, for example, an ecosystem where carbon may shift from storage to source due to warming.
3. Get local support – too many projects disrupt and damage the surrounding communities, so securing and maintaining local support is key.
4. For residual emissions only as a last resort: Offsets should not be used to allow an organization to continue business as usual without changing its internal operations or individual behaviour.
