How offsets, regulations and new standards may catalyze lower emissions and create new opportunities
The science is clear: Climate change is predominantly caused by the emission of greenhouse gases into the atmosphere.1 The atmosphere is composed of many gases, but one, carbon dioxide (CO2)—at a 0.042% concentration today, up from only 0.031% 50 years ago2—is the main driver of climate change.3 It may seem counterintuitive that such a small amount of CO2 can warm an entire planet, but it is the most abundant “greenhouse,” or heat-absorbing, gas.
While 99% of the atmosphere is nitrogen and oxygen, they do not absorb the Earth’s heat. Much like a tiny virus that can make you sick, CO2 in the atmosphere is minuscule but mighty.
Zeroing out most emissions—by replacing fossil fuels with clean energy technology, improving energy efficiency and reducing other sources of emissions—will not be enough to halt and reverse climate change.4 To keep global warming trends below 2º Celsius (C), the threshold outlined by the 2015 Paris Agreement5 and recommended by scientists to avoid major future climatic damages, CO2 removal technologies, potentially both nature-based and mechanical, will be needed. To reach negative net emissions by 2050, carbon removal (along with other strategies) will be necessary.
Desire for a net-zero world has led to the expansion of the global carbon market—an important investment area
This desire for a net-zero world, in which greenhouse gases emitted are canceled out by those removed from the atmosphere, has led to a significant expansion of the global carbon (shorthand for carbon dioxide, CO2) market. In a carbon market, technologies that reduce the amount of carbon a company (or an individual) produces—their “footprint”— create units of value called carbon offset credits, along with systems for certifying, registering and trading them.
Furthered by regulation and societal pressure, verified carbon credits have become an emerging investment area for companies and individuals as well as investors who may wish to help solve climate change and also seek to achieve long-term returns. However, the carbon market’s growth has been uneven, with notable national variances. The U.S., for example, has no current federal carbon regulation but does have two regional compliance markets.
Carbon removal technologies include nature-based and mechanical solutions. Both approaches can create carbon offsets that can be held, sold and traded on exchanges by those who want help compensating for carbon emissions occurring elsewhere. Many companies, governments and individuals are more than willing to purchase carbon offsets.
Forestry is the current dominant carbon offset solution. Forests sequester carbon through the growth of trees, which pull CO2 out of the atmosphere and combine it with soil nutrients and water to grow. The segment remains a particularly appealing removal offset, especially as mounting scrutiny is given to some avoidance offsets (being paid to avoid a CO2- emitting activity). Forestry also offers the potential for even greater stewardship opportunities.
Carbon market standards are still new and evolving. What exists today may not be right for the future. Here’s some background on the carbon market opportunity, including forestry offsets, as well as some of the standards and limits to consider.
Carbon regulation and market development
Carbon regulation to reach a net-zero emissions world has been in development since 1990, when the first of a series of international reports began showing the growing urgency of action to reverse climate change (EXHIBIT 1). Regulation, by creating a pricing mechanism, incentivizes emissions reductions, carbon offsets and investment in technologies to reduce emissions.
But while the scientific evidence of climate change has strengthened, carbon regulation has not kept pace, developing only slowly. The share of global emissions subject to regulation was roughly stagnant from 2005–11. Recently, however, the share of global emissions covered by regulation has grown sharply, to 22% globally in 2021 from 5% in 2010.6
Regulatory coverage has risen steadily every year since the 2015 Paris Agreement. New carbon regulations (implemented and scheduled) jumped in 2021 as countries sought to show leadership in advance of November’s U.N. Climate Change Conference 26 (COP26) in Glasgow, where countries will negotiate measures for addressing climate change. Carbon emissions are now subject to regulation worldwide.
Carbon regulation has grown steadily, albeit slowly, over time
Global participation in carbon regulation: Growing but uneven adoption
Global carbon regulation has expanded notably
A global patchwork of regulation created a wide range in price for a ton of carbon or its equivalents (tCO2e)
The latest on carbon pricing: governments and markets, EU and U.S.
Historically, carbon pricing has been higher when calculated by governments for the purposes of a carbon tax than when priced by markets in emissions trading systems. If, in the future, markets were constrained by lower allowable emissions allotments (by governments acting more aggressively to reach net-zero goals), ETS prices would increase. Differences in regional carbon prices, often the outgrowth of more lax emissions standards in some locations, have led the European Commission’s Fit for 55 plan10 to include a proposed “carbon border adjustment mechanism,” much like a tax, to prevent carbon leakage: the transfer of carbon-intensive activities to jurisdictions with laxer emissions rules. These constraints are policy decisions, either through the levying of taxes, typically based on a set carbon price, or through emissions caps that set maximum emissions, with carbon prices moving in a trading system.
Of note, there is no current U.S. federal carbon regulation. Despite signing the Paris Agreement in 2015, the U.S. began withdrawal in 2017 and formally dropped out on November 4, 2020. During this time, carbon regulation was stagnant. The U.S. formally rejoined on February 19, 2021, after President Joe Biden signed an executive order.
While there is not a carbon price in the U.S. on which to base regulation, there is a pricing framework to aid policy decisions. In early 2021, the Biden administration revised the federal social cost of carbon, a value per tCO2e to guide federal cost-benefit analyses of greenhouse gas emissions, to inform planning for setting a carbon tax or an ETS carbon emissions cap.11 The estimate was temporarily set to USD 51 per tCO2e—the prevailing price during the Obama administration.12 During the Trump administration, carbon was priced as low as USD 1 per tCO2e. An interagency working group is presently reviewing the latest science and economics to develop a new estimate, due January 2022.13 There is speculation a price could be set above USD 125 per tCO2e.14 The UK updated its regulatory pricing guidelines in September 2021, with this year’s ranges between GBP 122 and GBP 367 per tCO2e.15 Debate is growing over the use of social cost of carbon to inform policy,16 yet the conversation itself highlights the surging interest and focus on the developing carbon market.
Two types of CO2 removal technologies
In order for carbon, and carbon offsets, to trade on exchanges that carbon pricing has and will continue to foster, carbon removal technologies are a linchpin. Such technologies include:
- Nature-based solutions that manage ecosystems like forests, mangroves, kelp beds and soils that naturally sequester CO2.
- Mechanical removal of CO2 from air or the ocean with direct capture technologies that use machines to extract CO2 to create other carbon-based materials, including plastics, carbon-embedded cements and rocks buried deep underground.
Projects using these technologies to remove or reduce a carbon footprint can be verified for carbon offset credits. Companies and individuals can purchase verified carbon credits to reduce their overall emission counts. Investors can invest in these types of environmental projects or technologies to help provide climate change solutions and for their long-term return potential.
Carbon registries: key for offset verification and certification
Carbon registries can vary in specialization and regional footprint
Types of carbon emission offsets
Offsets can take two main forms:
- Avoidance offsets are generated by activities that reduce future emissions through prevention—for example, by building a wind farm instead of a new natural gas energy plant.
- Removal offsets extract carbon from the atmosphere or ocean by nature—such as forestry—or by mechanical removal.
Of late, avoidance offsets have come under scrutiny, especially as energy from renewables becomes more cost- competitive with fossil fuels. Evolving carbon regulations and verification standards may prompt stricter requirements for offsets, particularly around verification of carbon offset delivery and proof that projects do not result in leakage. Ultimately, carbon markets develop to provide financial incentives to reduce emissions.
Forestry represents the majority of both removal offsets and total offsets, by tCO2e, across all registries. In 2021, forestry represented 40% of all offsets registered—both those available on the market (called “issued” projects) and those already purchased (called “retired” projects). U.S. registries have significant forestry holdings. For example, at Climate Action Reserve, a major U.S. registry, forests accounted for over 80% of offsets in 2019. Standards and projects are also evolving for other nature-based removal offsets, including mangroves, kelp beds and soils, as early standards did not consistently deliver carbon removal.18
Technologies to directly capture carbon from the air or oceans are still in early development. Major barriers to adoption relate to their materials and energy requirements,19 as well as costs (estimated low ranges are from USD 250–USD 600 per tCO2e) that far exceed the current price of carbon in the compliance or voluntary markets (EXHIBIT 3).20 The largest facility, recently opened under ideal conditions in Iceland, took 18 months to build and will annually remove the equivalent of only 860 U.S. gasoline-powered cars.21,22
A forestry case study: trees’ efficiency in capturing carbon
Forests remove carbon from the atmosphere because trees grow by taking in CO2 and combining it with soil nutrients and water. Forestry carbon offsets are generated by the growth of forests as trees mature and sequester carbon in their wood. It takes roughly 40 years for a hardwood tree to sequester 1 tCO2e.
Most offset projects relate to reforestation, where trees are replanted or grown where a forest once stood, or afforestation, where trees are planted where they have not previously stood. These projects are designed to maximize carbon removal, a different approach from that taken with mature forests, which have less sequestration potential. In mature old-growth forests, avoided deforestation offsets have been used to incentivize leaving trees standing, but they have come under scrutiny for fear of leakage.
Varied standards have developed for forestry offset certification to ensure common practices and measure whether they deliver their stated carbon removal targets. However, there is room for improvement (EXHIBIT 5). A review of offsets from available registries has shown that some forestry projects have been overcredited; for these projects, carbon removal assumptions were systematically low because they reflected carbon removal for the wrong tree species.23
This highlights the need for making the definitions and methods to calculate carbon removal more robust, to ensure accurate delivery.
How forestry projects are credited could be improved
A criticism of forest offsets has emerged: that primarily single-species tree farms are being grown rather than developing healthy ecosystems. By contrast, the highest quality forestry carbon offsets could provide forestry stewardship, protecting and expanding forests critical for carbon removal and global forestry health,24 with pricing reflecting the costs to deliver sustainability goals.
This would allow for the bundling of positive outcomes from forestry offsets, including:
- Carbon removal by capturing CO2 from the atmosphere and transforming it into biomass (i.e., trees, kelp, mangroves). This requires planting, watering and potentially fertilizing to “farm” carbon removal.
- Meeting the conservation goal of protecting natural land; this may be of special interest to countries making “30 x 30” pledges in advance of COP26 (protecting 30% of land and ocean for conservation by 2030).
- Meeting the biodiversity goals of planting trees and monitoring wildlife to develop healthy ecosystems and support biodiversity.
- Supporting rural economies by creating jobs and access to forests for tourism and recreation.
- Supporting indigenous populations in maintaining cultural traditions through access to forests and creating an income source in managing land (our analysis to create EXHIBIT 4 found that several U.S. projects are managed by indigenous people).
- Lowering wildfire risk by removing debris and other active fire reduction management strategies. The history of fire suppression activities in certain dry forests (e.g., the western U.S.) with natural wildfire cycles have left excess fuel for fires to burn more intensely once ignited. With increased wildfire risks due to climate change, intentional management may lower the risks of catastrophic, large-scale fires,25 but this requires careful management, clear standards and scientific research to guide activities.
Climate adaptation by planting tree species for projected regional climate change conditions to improve long-term forest resilience.
Offsets’ current physical limits, with a likely rise in demand ahead
There is the potential for an offset supply issue, given the likelihood of increased demand as corporations strive to meet their net-zero commitments. This could put substantial pressure on carbon prices.
Consider EXHIBIT 6: In 2019, global emissions from all sources reached 36 billion tCO2e. The Russell 3000 Index, benchmarking the entire U.S. stock market, emitted 7 billion tCO2e.
Global forests sequester significant CO2 from the atmosphere annually. Measuring this removal over the last decades using satellites, scientists estimate that 7.6 gigatons (Gt) of CO2 e are absorbed by forests annually, as represented by the dotted purple line in the chart.26 But this uptake of carbon is not a global offset to be monetized, as it does not create additional removal to reduce emissions and slow or reverse climate change. For corporations to achieve net-zero emissions by offsetting their total global emissions by forestry alone, the world would have to more than double this natural process. Meeting the annual carbon removal required by the Paris Agreement to reverse climate change and stop further warming (if 2ºC or 1.5ºC targets are the goal) by 2100 would demand a sizable scaling up, as shown by the dotted purple line in Exhibit 6.
Yet we estimate a global offset supply of only 0.5 Gt CO2e, highlighting the need for significant expansion to reduce emissions and meet net-zero goals in the coming decades. Of course, forestry will not be the only solution, but it is the dominant (40% of offsets in 2019) and only scalable removal method today.
The supply of carbon offsets currently listed on registries is small compared with U.S. corporate emissions
Globally, however, as human activities emit CO2 beyond what the Earth system can naturally absorb in forests and oceans, ecosystems are likely to become more stressed and oceans warmer, potentially reducing these natural sinks and leaving even more carbon emissions in the atmosphere each year, accelerating climate change. As long as global emissions exceed removal, climate change will follow.
Ultimately, the global climate warms in proportion to the amount of CO2e left in the atmosphere. Every ton of carbon emissions matters. Solutions need to scale to reduce global emissions; offsets play a part, but they are not the sole solution.
What does this all mean?
To reach a net-zero world, emissions need to decline. To keep global temperature rises below 2ºC, both nature-based and mechanical offsets will need to scale. High quality, nature-based offsets such as forests may provide additional positive economic, natural, cultural and other outcomes. Global coordination, such as the COP26 meeting in Glasgow and private sector efforts led by the Taskforce on Scaling Voluntary Carbon Markets, will bring carbon markets and offset development further into focus.
Investing during a time of climate change
Mitigating and reversing climate change will take significant investment. Up to USD 4 trillion per year will be needed globally through 2050 to achieve a 1.5°C target across various sectors, such as power, iron and steel, cement, chemicals, transport, aviation, shipping, agriculture and buildings.27
- Replacing high emission activities, such as fossil fuel energy generation, with clean energy.
- Reducing emissions in all sectors as close to zero as feasible, given technological availability. This means improving energy efficiency where there are no zero-carbon alternatives.
- New technologies, materials and recycling to decarbonize sectors beyond energy production. This includes hard-to- decarbonize sectors without clear technological solutions, such as aviation and cement.
- Waste and agriculture management for the reduction of methane, a short-lived greenhouse gas whose main impact lasts a decade.
For processes that cannot be replaced with zero-carbon alternatives now and/or in the future, carbon removal through nature-based or mechanical means will be necessary. Investment today is critical—to deploy existing solutions and develop the technologies of tomorrow needed to combat climate change.
Taking personal action
If you are curious about your own carbon footprint, there are calculators to identify your carbon emission total and its sources. In the U.S., the EPA offers a calculator that can help quantify your household carbon footprint.28 The World Wildlife Fund has developed country-specific calculators.29
Given the likelihood of growing carbon regulation worldwide and cross-border carbon taxes, business managers would be prudent to begin monitoring CO2e emissions and budgeting for potential future costs.
To date, several nongovernmental organizations have been involved in forest conservation and carbon offset projects, and they have provided the research, monitoring and local engagement to make many naturebased solutions possible. For further information, see the Trust for Public Land, National Forest Foundation and Conservation International.
Compliance and voluntary carbon registries developed in response to past regulation and social pressures. In the near future, new U.S. regulations may catalyze carbon reductions. The infrastructure package before the U.S. Congress could reduce annual emissions by 1 billion CO2 by 2030 if implemented.30 The EU’s Fit for 55 package outlines measures to reduce emissions by at least 55% by 2030.
