Climate Action: What It Is, How It Works, and What Your Company Can Do

Climate action is the set of measures—political, business, technological, and social—aimed at reducing greenhouse gas emissions and adapting human systems to the impacts of climate change that are already inevitable. It is not an abstract concept: it has international frameworks that define it, metrics that measure it, and specific actors who implement it or evade it. Faced with the magnitude of the problem, the most common response is one of two: paralysis due to feeling overwhelmed, or symbolic action with no real impact. Neither approach works. What does work is what this article describes: understanding the framework, identifying the real levers for change, and acting based on data.

Climate action operates in two dimensions that are often confused.

Mitigation vs. adaptation: two complementary approaches

Mitigation seeks to reduce the cause: cutting GHG emissions to slow global warming. It includes the transition to renewable energy, the electrification of transportation, energy efficiency in buildings, and industrial decarbonization.

Adaptation seeks to manage the consequences: preparing infrastructure, food systems, and communities for the climate impacts that are already inevitable given the accumulated warming. It includes water risk management, the redesign of coastal infrastructure, and crop diversification in the face of climate variability.

Both are necessary and complementary. A company that only mitigates without adapting ignores the physical risks to its operations. One that only adapts without mitigating contributes to the problem, which exacerbates its own risks.

Individual, Corporate, and Systemic Climate Action

These are three levels with distinct logics:

Individual: decisions regarding consumption, mobility, and diet. Their aggregate impact is real but insufficient as the primary lever for change.

Corporate: measuring and reducing carbon emissions, investing in clean technologies, and exerting pressure on the supply chain. This is where the majority of emissions manageable in the short term are concentrated.

Systemic: regulation, fiscal policy, sectoral standards, and international cooperation. Without this level, the previous two operate without the necessary enabling conditions.

The most common mistake in climate communication is treating these three levels as equivalent or interchangeable. They are not.

The global framework defining climate action today

The Paris Agreement and the NDCs

The Paris Agreement (2015) established the goal of limiting global warming to 1.5°C above pre-industrial levels. The central mechanism is the Nationally Determined Contributions (NDCs): emission reduction commitments that each country updates every five years.

The problem is that the sum of the current NDCs is not sufficient to achieve the 1.5°C goal. The gap between declared commitments and the actual emissions trajectory is the statistic that best explains why the urgency has not gone away. [Insert reference to UNEP Emissions Gap Report here]

Corporate Commitments: SBTi, Net Zero, and Race to Zero

Alongside the framework established by nations, companies have their own climate action frameworks:

Race to Zero: a UN initiative that brings together companies, cities, and investors committed to achieving net-zero emissions by 2050.

Science Based Targets initiative (SBTi): validates that a company’s reduction targets are consistent with the Paris Agreement scenarios. It requires a verified emissions inventory as a starting point.

Net Zero: a commitment to reduce emissions as much as possible and offset the remainder. The SBTi’s Net Zero standard is more rigorous than the generic use of the term, which in many cases masks greenwashing.

Why Optimism Coupled with a Sense of Urgency Matters

The Risk of Eco-Pessimism: Paralysis Disguised as Realism

Eco-pessimism—the conviction that climate change is already irreversible and that no individual or collective action has any effect—is a stance that is marketed as clarity but produces the same result as denial: inaction. The data does not support this view. Per capita emissions in countries with ambitious climate policies have verifiably fallen. The costs of solar and wind energy have dropped by more than 80% in a decade. [Insert IRENA source here] The trajectory is insufficient, but it is neither linear nor set in stone.

What Distinguishes Active Optimism from Passive Optimism

Passive optimism hopes that technology or governments will solve the problem without any action on one’s part. Active—or sense-of-urgency—optimism recognizes that the outcome depends on decisions made now, takes responsibility within one’s own sphere of influence, and acts without waiting for perfect conditions.

For a company, the practical difference is this: passive optimism produces statements of intent for 2050.

Who Is Taking Action and With What Results

Companies That Have Reduced Verified Emissions

Some companies have demonstrated that it is possible to decouple economic growth from emissions. Maersk, the world’s largest shipping operator, has committed to carbon neutrality by 2050 and has begun operating ships powered by green methanol. Microsoft has committed to becoming carbon-negative by 2030 and to eliminating all of the company’s historical emissions by 2050. [Insert verified sources here]

These examples do not prove that the problem has been solved. They demonstrate that corporate climate action at scale is achievable when the will and structure are in place.

Citizen Movements and Influence on Public Policy

Movements such as Fridays for Future and fossil fuel divestment campaigns have demonstrably influenced public policy decisions and the positioning of investment funds. Cumulative divestment from fossil fuel assets exceeded $40 trillion in global commitments, according to 2023 data. [Insert source here]

Their importance is not merely symbolic: they create the political context that enables game-changing regulations for all companies.

The Role of Investors in the Energy Transition

Institutional investors aligned with ESG criteria and frameworks such as the TCFD (Task Force on Climate-related Financial Disclosures) are integrating climate risk into their capital allocation decisions. This has a direct impact on the cost of financing for high-emission companies and on access to capital for those that demonstrate verifiable decarbonization trajectories.

How a company can move from intentions to real climate action

Step 1 – Measure: The emissions inventory as a starting point

There can be no credible corporate climate action without data. The first step is to calculate the corporate carbon footprint—Scope 1, 2, and relevant Scope 3 emissions—in accordance with the GHG Protocol or ISO 14064-1. Without this assessment, any reduction commitment is merely declarative.

Step 2 – Reduce: Prioritize by Impact and Cost

With the emissions inventory broken down by source, it is possible to construct a mitigation curve that relates the cost of each measure to its impact in metric tons of CO₂e. Energy efficiency measures typically yield a positive financial return in addition to reducing emissions. Fleet electrification and the purchase of renewable energy are the next common steps. Carbon offsets are a last resort, not the first option.

Step 3 – Communicate: Verifiable transparency, not greenwashing

Climate communication not backed by verified data is greenwashing, with the reputational and regulatory risks that entails. The rule of thumb: do not communicate more than can be demonstrated with a third-party-verified inventory and targets with specific dates and metrics.

Frequently Asked Questions

What is the difference between climate action and sustainability? Sustainability is a broader concept that includes social, economic, and environmental dimensions. Climate action specifically refers to the set of measures aimed at reducing GHG emissions and adapting to climate change. All climate action is part of sustainability, but not every sustainability initiative constitutes climate action.

Is individual action enough to curb climate change? Not as the primary driver. Studies on the impact of individual consumption decisions show that, while they have an aggregate effect, structural emissions linked to energy generation, heavy industry, and freight transportation require systemic changes that are beyond the reach of the individual consumer. Individual action matters more as a market signal and as part of the cultural context than as a direct reduction in emissions.

What is greenwashing, and how can it be identified? Greenwashing is the practice of communicating climate commitments or achievements that are not backed by verifiable emissions reductions. Red flags include: targets without specific deadlines; the use of carbon offsets of unverified quality to claim carbon neutrality; and claims about individual products without context regarding the company’s overall emissions profile.

Where does a company that wants to take climate action start? By measuring. A Scope 1 and 2 emissions inventory is the bare minimum. Without that starting point, it is not possible to set reduction targets with a realistic basis or to access validation frameworks such as the SBTi.
