Corporate climate action is the full range of steps companies take to measure, reduce, and publicly report their greenhouse gas emissions, while preparing their operations for the physical and economic impacts of climate change. It spans everything from switching to renewable energy and redesigning supply chains to setting public emissions targets and disclosing climate-related financial risks. What started as voluntary pledges has rapidly evolved into a structured field with standardized frameworks, third-party validation, and increasingly binding regulations.
The Core Pillars
Corporate climate action generally rests on four interconnected efforts: reducing a company’s own emissions, adapting operations to withstand climate impacts, transparently disclosing progress, and influencing broader change beyond the company’s walls. The first two are operational. The third is about accountability. The fourth recognizes that no single company operates in isolation, and that lobbying, industry partnerships, and public advocacy all shape the pace of decarbonization.
A widely used framework called the 1.5°C Business Playbook, developed by the Exponential Roadmap Initiative, organizes these four pillars into a practical roadmap for companies of any size. The goal is concrete: halve emissions by 2030, reach net zero as soon as possible, and use whatever market influence a company has to accelerate the transition across its sector.
Measuring Emissions Across Three Scopes
Before a company can reduce anything, it needs to know where its emissions come from. The standard accounting system, developed by the Greenhouse Gas Protocol, divides corporate emissions into three categories. Scope 1 covers direct emissions from sources the company owns or controls: fuel burned in its furnaces, boilers, and vehicles. Scope 2 covers indirect emissions tied to the electricity, heating, or cooling the company purchases.
Scope 3 is the big one. It captures everything else in a company’s value chain: the emissions embedded in raw materials it buys, the transportation of its products, business travel, and even how customers use and dispose of what the company sells. For most companies, Scope 3 represents the vast majority of their total footprint, sometimes 80% or more. It’s also the hardest to measure and the hardest to control, because it depends on the behavior of suppliers, logistics partners, and consumers.
The Decarbonization Hierarchy
Companies with credible climate strategies follow a specific priority order known as the mitigation hierarchy. The first priority is prevention: avoiding emissions entirely by eliminating unnecessary activities or choosing zero-emission alternatives from the start. The second is reduction: improving efficiency, switching fuel sources, or redesigning processes to cut emissions that can’t be fully avoided. The third is substitution: replacing high-emission inputs with lower-emission alternatives.
Only after exhausting those options should a company turn to neutralization, using biological approaches like reforestation or technological solutions like carbon capture to counterbalance whatever emissions remain. This sequence matters because it prevents companies from skipping the hard work of actual emissions cuts and jumping straight to offsets, which has been one of the most common criticisms of corporate climate programs.
Net Zero vs. Carbon Neutral
These two terms sound interchangeable, but they set very different bars. Carbon neutrality means a company has balanced its carbon emissions by purchasing enough offsets or carbon credits to mathematically zero out its footprint. The company may not have reduced its actual emissions at all.
Net zero is far more demanding. Under the Science Based Targets initiative’s Corporate Net-Zero Standard, a company must cut all possible emissions, typically more than 90%, before 2050. Only the final residual slice (roughly 10% or less) that genuinely cannot be eliminated may be addressed through permanent carbon removal and storage. A company is only considered to have reached net zero after achieving its long-term science-based target and neutralizing those residual emissions. There’s no shortcut through offsets.
The standard also requires near-term targets: companies must roughly halve their emissions before 2030, ensuring immediate action rather than distant promises. An independent validation process checks that each target aligns with limiting global warming to 1.5°C above pre-industrial levels.
How Companies Set and Validate Targets
The Science Based Targets initiative (SBTi) has become the dominant system for validating corporate climate targets. Its Corporate Net-Zero Standard requires targets to cover all material sources of emissions across a company’s value chain, not just the easy-to-measure ones. Targets must follow a clear timeframe, with net zero reached by 2050 at the latest, and they’re subject to an independent accountability framework.
Beyond internal reductions, SBTi encourages companies to invest in “beyond value chain mitigation,” funding emissions reductions or carbon removal projects outside their own operations. This isn’t a substitute for cutting their own emissions. It’s an additional expectation.
Adoption is widespread but uneven. In the primary chemicals industry, about 58% of publicly traded companies have approved SBTi targets. In steel, 77% of large publicly traded companies integrate climate considerations into strategic decisions. In aviation, that figure is 75%. Yet a 2024 World Economic Forum analysis of eight of the most emissions-intensive sectors found that none are currently on track to achieve net zero by 2050.
Disclosure and Reporting Requirements
Corporate climate action increasingly isn’t optional. Two major forces are pushing companies toward mandatory, standardized disclosure.
The first is regulation. The European Union’s Corporate Sustainability Reporting Directive (CSRD) began requiring certain large companies to report under new sustainability rules for the 2024 financial year, with those reports published in 2025. The EU has since narrowed the scope, focusing requirements on companies with more than 1,000 employees, and delayed timelines for smaller waves of companies originally set to begin reporting in 2025 and 2026.
The second force is global standards. In June 2023, the International Sustainability Standards Board issued IFRS S2, a climate disclosure standard that builds on the earlier recommendations of the Task Force on Climate-related Financial Disclosures (TCFD). IFRS S2 requires companies to disclose how climate risks and opportunities could affect their cash flows, access to finance, and cost of capital. It covers four areas: governance processes for overseeing climate risks, the company’s strategy for managing those risks, how the company identifies and prioritizes climate threats, and its actual performance against any targets it has set. Countries around the world are adopting or adapting IFRS S2 into their own regulatory frameworks.
Avoiding Greenwashing
As corporate climate claims have proliferated, so has skepticism. A company that buys cheap offsets and calls itself “carbon neutral” without meaningfully cutting emissions faces reputational, legal, and regulatory risk. Several frameworks now exist to help companies make credible claims.
The Voluntary Carbon Markets Integrity Initiative (VCMI) publishes a Claims Code of Practice that sets specific requirements. To make any VCMI-recognized claim, a company must set science-aligned near-term emissions reduction targets, commit to reaching net zero by 2050, and purchase only high-quality carbon credits representing real emissions reductions or removals outside its own value chain. All near-term targets must be established through a credible science-aligned framework and should be validated by a third party.
The key principle across all credible frameworks is the same: carbon credits and offsets supplement deep emissions cuts. They never replace them. Companies that lead with actual reductions and treat offsets as a last resort for truly unavoidable emissions are the ones whose claims hold up to scrutiny.
What Credible Action Looks Like in Practice
A company taking meaningful climate action typically follows a recognizable pattern. It starts by measuring its full emissions footprint across all three scopes, using the Greenhouse Gas Protocol or an equivalent methodology. It sets near-term and long-term reduction targets validated by a credible third party. It prioritizes direct emissions cuts through energy efficiency, renewable energy procurement, supply chain changes, and process redesign. It discloses its progress annually using standardized reporting frameworks. And it uses its influence, through procurement policies, industry coalitions, and public advocacy, to push for systemic change beyond its own operations.
What separates serious corporate climate action from performative gestures is specificity, accountability, and the willingness to tackle Scope 3 emissions even when they’re difficult to measure and outside the company’s direct control. The frameworks, standards, and regulations now in place make it harder than ever to claim ambition without demonstrating results.
