If you’re considering the environmental impact of hosting an event, you might focus on logistics like energy efficiency, the food you serve, or the event materials distributed to attendees. While focusing on these types of areas can help soften the event’s environmental footprint and greenhouse gas emissions, it’s hard to build a truly sustainable event based on operational choices alone.
The problem is that events, especially large ones like conferences or major sporting events, tend to involve decisions outside your control, like how attendees travel to your event and how they consume resources at the event venue. These factors can create a significant negative impact, even when sustainability measures are in place.
Carbon emissions from people flying in to attend, one of the largest contributors to event related greenhouse gasses, can easily overshadow the emissions you avoid by reusing name badge lanyards from previous events, for example. And you might put out compost bins next to landfill and recycling containers, but at a busy, crowded event, an attendee might haphazardly throw whatever trash they have on hand into whatever bin they first see.
That’s not to say you shouldn’t try to focus on logistics, as sustainability isn’t all or nothing. Every step helps. And you may be able to make meaningful progress toward sustainability goals, based on choices like venue location, reducing reliance on traditional power plants, and improving energy savings through more efficient or renewable energy sources, such as swapping diesel generators for solar ones.
But if you really want to make your event net zero or at least get closer to minimizing environmental impacts, buying high quality carbon credits and other environmental credits, like renewable energy certificates, is often critical.
Doing so isn’t a shortcut to event sustainability. Instead, carbon credits can help you account for the areas outside your control, like travel emissions, as well as taking responsibility for the emissions impact of all the little details that you cannot reduce or avoid. Many carbon credit projects work to store carbon or support initiatives where emissions are actively reduced or carbon removed from the atmosphere, often at a large scale.
To ensure credibility, it’s important that carbon credits follow strict verification standards aligned with global frameworks like those supported by the United Nations. This helps prevent issues like double counting, where the same emissions reduction is claimed more than once.
Terrapass makes it easy to buy carbon credits for both individuals and businesses. You can buy credits that align with emissions from specific events like weddings, those that help address the impact of flying, or other personal or corporate packages based on your emissions goals.
Case Study: The Olympics
How Carbon Credits Help Address Residual Emissions from Large Events
The Olympics haven’t always had the best environmental reputation, such as with the legacy of host cities spinning up massive new sporting facilities that soon become abandoned. Recent Olympic Games, however, have made environmental sustainability and social responsibility more of a focal point.
For example, the Paris 2024 Games included significant sustainability efforts, such as with 95 percent of the venues being temporary or from preexisting infrastructure. Event organizers also added grid connections so that nearly all energy consumption came from renewable sources, reducing dependence on fossil fuel-based power plants and increasing overall energy savings, instead of relying as much on sources like diesel generators.
Yet despite reducing emissions by more than half compared to the preceding Rio and London summer Olympics, the Paris Games still had a carbon footprint of 1.59 million tCO2e, which was more than Netflix’s total Scope 1 to 3 emissions that year, for comparison. Nearly half of those emissions came from spectators traveling to the Games, indicating how hard it is to cut your way to zero while still maintaining the power of live events.
So, Paris 2024 spent €12.1 million on carbon sequestration and avoidance credits that matched the 1.59 million tCO2e residual emissions total. This included financing projects such as cooking systems in several African countries, solar projects in Senegal and Vietnam, deforestation protection in Guatemala and Kenya, and mangrove restoration in Senegal. These types of initiatives help store carbon and contribute to carbon removed from the atmosphere on a large scale. The Organising Committee also financed some forestry projects within France to more directly compensate for emissions within its control.
Another type of credit usage showed up recently during the Milano Cortina 2026 Olympics. Their commitment to using virtually all clean electricity during the Games was made possible in part by Italian electricity company Enel procuring Guarantees of Origin, essentially a European version of renewable energy certificates, that correspond with renewable energy, as PBS reported.
And for the upcoming LA 2028 Olympics, the host has established an internal carbon price as a way to incentivize efficiencies while also generating funds for the LA28 Resilience Champions Fund. This will finance local improvements rather than international carbon offsets. For example, the fund will focus on areas including cooling solutions like native tree planting, wildfire resilience such as by planting fire resilient native plants, and ocean protection such as through beach cleanups.
Going forward, carbon credits could become even more important to Olympic events, considering that in 2020, the International Olympic Committee (IOC) set a requirement that, starting in 2030, all host cities would need to go even further by making the Games climate positive. Granted, that has arguably since been softened, such as with Brisbane 2032’s contract being adjusted to make being climate positive more of a goal than a necessity.
Still, carbon credits and similar financing mechanisms will likely continue to provide ways for host cities to address unavoidable emissions, such as those associated with flying, while reducing their overall negative impact. In addition to addressing emissions, carbon credits also typically provide co benefits that support health and other positive outcomes in local communities.
Terrapass offers carbon credits across a broad range of project types, such as reforestation and landfill gas capture. You can support a mix of projects and their associated benefits with a monthly subscription of carbon credits for just $8.50 per employee that offsets what many businesses emit during normal operations, or you could build a carbon credit portfolio that aligns more with specific events if you’re hosting.
Using Carbon Offsets for Your Own Events
While you’re probably not hosting an Olympic sized event, similar strategies can be scaled to all sorts of other sustainable event planning, ranging from conferences to parties.
To fully balance emissions, an event organizer would ideally calculate total emissions. Depending on the scale of your event, this might require working with a third-party sustainability consultant that can assist with carbon accounting, or you might be able to use online carbon footprint calculators.
Even if you can’t map out all of your emissions, you might calculate some of the largest sources, like flight emissions. A virtual event might avoid a big chunk of these travel emissions, but that might run counter to your goals of facilitating in person bonding that’s hard to replicate online. So, if you’re hosting a company retreat in another city, for example, you could add up the flight miles among your employees and calculate the associated emissions.
While this doesn’t account for everything, such as on-site emissions like hotel energy usage and food, it can give you a good starting point. By at least purchasing flight carbon offsets, organizers can take responsibility for what is typically one of the largest emissions components of any large event, particularly those tied to greenhouse gasses. Meanwhile, you can make operational choices for your corporate event, like choosing a sustainable venue, reducing reliance on fossil fuel-based power plants, and improving energy savings through efficient practices.
You also may be able to buy carbon credits that align with the approximate emissions from specific types of events. For example, Terrapass sells carbon offsets for weddings, which you can scale according to how many guests you have and whether you also want to account for honeymoon emissions and the impact on water systems.
Whether you’re hosting a personal event or a large corporate one, Terrapass offers a mix of ready to buy carbon offset packages, or our team of sustainability experts can help you develop a custom carbon offset plan as you aim to balance your carbon footprint. By supporting verified projects that operate at a large scale, you can address emissions responsibly while contributing to meaningful climate solutions.

Key takeaways
- SBTi is the default reference point for corporate climate action: 51% of Fortune Global 500 companies now hold net-zero targets, up from 8% in 2020, and over 11,000 organizations worldwide have SBTi-validated targets.
- Net Zero Standard V2 redefines climate leadership as reducing emissions and mitigating ongoing emissions, not reduction alone.
- The new standard adds flexibility through five-year cycles, a “best efforts” standard, and an Asset Transition Method for companies whose path to net-zero doesn’t fit a straight-line trajectory.
- Voluntary carbon credits are formally recognized for the first time, with reduction and removal credits accepted from 2027, and removals required from 2035.
- Companies with 2030 targets keep using V1 for their current cycle and move to V2 in 2028; companies without targets can start using V2 on February 1, 2027.
Why every business needs to understand the SBTi Net-Zero Standard revision
The Science Based Targets initiative (SBTi) has become the default reference point for credible corporate climate action. Net-zero targets are now held by 51% of Fortune Global 500 (FG500) companies, up dramatically from just 8% in 2020, and more than 11,000 organizations worldwide have set SBTi-validated targets.
However, SBTi’s influence extends well beyond the companies formally participating in the program. Every business in the value chain of an SBTi participant will have to reduce its own carbon emissions, and businesses that aren’t SBTi participants themselves still look to the program for guidance on climate action.
In short, SBTi gives every business a credible blueprint for climate action, and companies that follow its principles can pursue climate action with confidence, whether or not they’re formally part of the program.
How will the Net Zero Standard revision affect business climate action?
SBTi participation is expected to grow. Despite strong target-setting participation among the F500, only 17% of companies use the SBTi Net Zero Standard V1 beyond target setting, largely because its rules have been seen as too rigid to apply in practice. Much of the Net Zero Standard revision has focused on creating more flexibility to enable higher participation. Medium and small businesses will also increasingly feel pressure for climate action, since SBTi mandates that its participants reduce carbon emissions across their value chains.
Net Zero Standard V2 also redefines climate leadership: leading climate action now means reducing emissions and mitigating ongoing emissions. Reducing your own emissions while ignoring the emissions you continue to release along the way is no longer considered leadership. Supporting voluntary carbon projects with high-integrity carbon credits is now backed by the leading authority on corporate climate action.
What lessons shaped the Net Zero Standard V2 revision?
The revision reflects a few learnings about what actually drives climate progress, and how SBTi built those lessons into the new standard.
| Net Zero Standard V1 Learnings | Net Zero Standard V2 Implementation |
|---|---|
| Making real short-term progress is more important and more difficult than making big long-term promises | Focus on short-term climate progress |
| Every company has a different path to net zero that doesn’t always fit generalized net-zero rules | Create asset transition plans based on each company’s unique asset lifecycles and capital planning |
| We need to mitigate our ongoing emissions to keep global carbon emissions in check | Reduce global carbon emissions by financing voluntary carbon projects with high-integrity carbon credits |
What are the key changes between the old and new Net Zero Standard?
Both versions of the standard are grounded in net-zero by 2050. However, the old standard treated climate leadership as simply reducing emissions, expected a long-term commitment to net zero, based emission reduction targets on generalized net-zero goals, revoked status from companies that fell behind on targets, and ignored voluntary carbon projects entirely.
The new standard treats climate leadership as reducing emissions and mitigating ongoing emissions. It shifts the focus to short-term progress through five-year cycles, and it bases emission reduction targets on both the net-zero goal and a company’s own asset decarbonization plan. A new Asset Transition Method lets companies set decarbonization targets through asset plans with committed, verifiable steps; an ambitious but achievable path based on a company’s starting point, financial resources, and technology, with multiple pathways to reflect the unique opportunities and constraints of different industries and companies.
Crucially, the new standard moves to a “best efforts” basis that creates real flexibility on progress against targets. Businesses that miss their targets can keep their status if they’ve used “every lever” within their control, and minimum progress rules will be set out in the SBTi Assurance Manual.
Finally, the new standard formally uses voluntary carbon projects to mitigate ongoing emissions. From 2027 through 2034, this mitigation is recognized, and both carbon reduction and removal credits are accepted. From 2035 forward, mitigation with carbon removal credits becomes required, with durability matching between the removal and the emission it offsets.
| Old Net Zero Standard | New Net Zero Standard |
|---|---|
| Grounded in net-zero by 2050 | Grounded in net-zero by 2050 |
| Climate leadership is reducing emissions | Climate leadership is reducing emissions and mitigating ongoing emissions |
| Make a long-term commitment to net-zero | Focus on short-term progress in 5-year cycles |
| Emission reduction targets are based on net-zero goal |
|
| Businesses who fall behind targets lose status |
|
| Ignores voluntary carbon projects |

When does the new Net Zero Standard take effect?
Companies with existing 2030 targets should continue using the old Net Zero Standard for their current cycle, and start using the new Net Zero Standard in 2028 to set targets for the next cycle (2030–2035).
Companies that don’t yet have targets can use the new Net Zero Standard starting February 1, 2027.
What are SBTi’s Category A and Category B companies?
The new Net Zero Standard splits companies into two categories, with different requirements attached to each.
Category A covers large companies from all countries and medium-sized companies from high-income countries. A company from any country qualifies if it meets at least one of: net turnover of €450 million or more, or 1,000 or more full-time employees. A company from a high-income country qualifies if its Scope 1 and 2 emissions are 10,000 tCO2e or more, or if it meets at least two of: balance sheet of €25 million or more, net turnover of €50 million or more, or 250 or more full-time employees.
Category B covers small companies from all countries and medium-sized companies from lower-income countries.
How do Scope 1 targets work under Net Zero Standard V2?
Scope 1 targets aim to transition companies to net-zero direct emissions by 2050 or sooner, and companies can choose from three approaches.
- Absolute emissions reduction follows a straight-line emissions trajectory from the target base year to the net-zero year.
- Emissions intensity reduction lets companies follow sector-specific pathways designed to reflect the reduction opportunities available in sectors like steel, cement, or chemicals.
- Asset transition is designed for companies whose capital stock turnover doesn’t follow a linear or sector pathway. These companies design a transition plan to operate existing assets efficiently and replace them with low-carbon assets, using predetermined milestones.
How do Scope 2 targets work under Net Zero Standard V2?
Scope 2 targets address emissions from purchased electricity through three pathways:
- Reducing electricity consumption,
- Reducing grid consumption by installing onsite or direct-line offsite clean energy generation, and
- Cleaning up the regional grid using market-based tools like PPAs, RECs, and GOs that drive clean energy development.
V2 introduces a dual Scope 2 framework requiring two separate targets, with an overall goal of 100% low-carbon electricity by 2040.
The location-based target addresses the carbon intensity of a company’s physical power use, and requires companies to show that their grid consumption is falling and/or that their physical grid use is getting cleaner; in other words, that their market-based solutions are actually making the grid cleaner.
The market-based (or zero-carbon electricity) target tracks a company’s use of low-carbon power generation contracts and Energy Attribute Certificates. It requires geographical matching of these certificates with electricity consumption based on deliverability regions (grid regions); annual matching is allowed, though hourly matching is encouraged. Category A companies with large electricity loads must report the percentage of their Scope 2 electricity consumption matched with low-carbon attributes on an hourly basis, and there’s an optional recognition framework for companies that meet hourly matching thresholds.
How do Scope 3 targets work under Net Zero Standard V2?
Scope 3 targets share the same 2050-or-sooner net-zero goal, but companies set near-term targets only for material emissions sources in their value chain and areas where they have real influence. Long-term Scope 3 targets are generally not required.
Limited, justified exclusions are allowed for near-term targets, including categories that individually account for less than 5% of total Scope 3 emissions, and activities where a company lacks practical influence, like leased assets it doesn’t operationally control, or the processing of sold products. Optional exclusions are also available in specific categories.
Companies can choose from three approaches to near-term Scope 3 targets:
- An overarching emissions reduction target, which follows a linear contraction of emissions from the base year to residual emissions of 10% or less by 2050 or sooner;
- An overarching supplier/customer alignment target, benchmarked against a growing share of tier 1 suppliers and customers reaching net-zero by 2050 or sooner; or
- A category- or activity-specific target, tailored for companies with concentrated emissions in particular Scope 3 categories or high-emitting activities.
What is “ongoing emissions mitigation” under the new SBTi standard?
This is one of the most significant additions in Net Zero Standard V2. Accelerated climate contributions are needed to help the world achieve climate objectives, limit temperature overshoot, mitigate transition risks, and support the scale-up of climate solutions, and V2 formally recognizes that. Ongoing emissions mitigation runs as a parallel track to companies also reducing their own emissions.
The framework is initially voluntary, with recognition available at three contribution levels to encourage early action.
- Engaged companies address more than 1% of total Scope 1, 2, and 3 emissions.
- Advanced companies address more than 10% of total Scope 1, 2, and 3 emissions, including 100% of Scope 1 and 2 emissions.
- Leadership companies address 100% of total Scope 1, 2, and 3 emissions with a contribution budget of $80/tCO2e.
Carbon credits used for this purpose have to meet certain quality standards. They must be ex-post (issued after the mitigation has actually occurred), independently third-party-assured, emissions reductions or removals, measured in tCO2e, that occur within five years prior to the reporting year. They must be sourced from outside the company’s own value chain. Further minimum criteria will be set to align with high-integrity frameworks, with additional details on the recognition program expected in the second half of 2026.
Starting in 2035, carbon removals become mandatory for Category A companies. From that point, the carbon removal coverage requirement rises linearly from 1% of Scope 1–3 emissions to 100% by a company’s net-zero year. Within that, 10% of long-lived GHG emissions must specifically be covered by durable removals, also rising linearly to 100% by the net-zero year.
How must companies neutralize residual emissions?
At a company’s net-zero target year and thereafter, it must reduce its Scope 1, 2, and 3 emissions to zero or to residual levels, and neutralize all residual emissions using eligible carbon removals. Those removals have to meet two conditions: they must occur within the same reporting period as the residual emissions they’re neutralizing, and long-lived GHGs must be neutralized with long-lived removals, matching the durability of the removal to the atmospheric lifetime of the emission being addressed.
What is the SBTi implementation hierarchy?
Net Zero Standard V2 also lays out how companies should prioritize their actions for credible target delivery, in three tiers.
- Direct actions, at the activity level, are actions that reduce emissions at the source within a company’s own operations and value chain; things like efficiency improvements, fuel switching, and engaging suppliers and customers to reduce their emissions.
- Actions within shared systems, or activity pools that reduce the emissions of shared systems like electricity or gas grids. This includes market instruments that convey low-carbon attributes, such as PPAs, RECs, and GOs, all of which must meet minimum integrity criteria that SBTi will elaborate on in future guidance.
- Sector-level actions relate to the same type of activity occurring in a relevant geography or system, in a way that meaningfully reduces the emissions a company is responsible for.

FAQ: SBTi Net-Zero Standard revision
What is the SBTi Net-Zero Standard?
It’s the framework the Science Based Targets initiative publishes for companies that want validated, credible net-zero targets tied to limiting global warming.
What is changing in the SBTi Net Zero Standard V2 revision?
The biggest changes are more flexibility (five-year cycles and a “best efforts” standard), a new Asset Transition Method for companies whose emissions don’t follow a straight-line path, and formal recognition of voluntary carbon credits for mitigating ongoing emissions.
When do companies need to switch to the new SBTi standard?
If your company already has 2030 targets, you keep using V1 for your current cycle and move to V2 in 2028. If you don’t have targets yet, you can start using V2 as of February 1, 2027.
Can companies use carbon credits to meet SBTi targets?
They can. Under V2, high-integrity carbon reduction and removal credits count toward mitigating ongoing emissions from 2027 through 2034. Starting in 2035, only removal credits count, and they need to be durability-matched to the emissions they offset.
What’s the difference between Category A and Category B companies under SBTi?
Category A is large companies everywhere plus medium-sized companies in high-income countries, based on thresholds like revenue, headcount, or emissions. Category B is small companies everywhere and medium-sized companies in lower-income countries.
What happens if a company misses its SBTi target?
Under the old standard, falling behind could cost a company its SBTi status. Under V2’s “best efforts” approach, a company can hold onto its status as long as it’s used every lever within its control, with minimum progress rules coming in the SBTi Assurance Manual.

The post SBTi Net-Zero Standard V2: What the Revision Means for Every Business appeared first on Terrapass.
For most businesses, the emissions that matter most sit outside their own walls. Scope 3 emissions, everything generated across your value chain, from the suppliers who make your inputs to the customers who use your products, typically make up the majority of a company’s total carbon footprint. Under the Corporate Sustainability Reporting Directive (CSRD), those value-chain emissions now have to be measured and disclosed with a rigour that spend-based estimates alone struggle to satisfy. This guide sets out how to improve Scope 3 data accuracy for CSRD: the calculation methods open to you, how to move from estimates to verified supplier data, and how to govern that data so it holds up to audit.
A carbon credit is a commitment that extends well into the future. The tonne of CO₂ compensated for today from a nature-based carbon project must remain out of the atmosphere for good, which means the forest behind the credit has to remain standing long after the transaction is complete. For any buyer, this raises a defining question: What ensures that the forest endures?
