Earth day 2026: How to run a high-impact sustainability campaign with nature-based solutions

Earth Day

mobilises over a billion people globally each year around climate action, nature protection, and environmental advocacy. Over the years, businesses have used it as a time to showcase their sustainability story.

However, much of what passes for corporate participation remains surface-level - a recycling initiative, a one-off volunteering day, a reworked sustainability pledge. These actions are not without value, but they fall short of what is now expected by customers, investors, and regulators, who are looking for

ESG commitments

that are specific, measurable, and independently verified.

The responsible businesses leading in 2026 are approaching Earth Day differently. They are using it not as a standalone campaign, but as a strategic inflection point - supporting initiatives that are measurable, verifiable, and set into long-term sustainable operations through nature-based solutions.

Earth Day

is a global environmental observance held annually on April 22nd, to raise awareness and drive action on climate change, biodiversity loss, and the need to protect the natural world. Since its launch in 1970, it has grown into the world's largest civic event, engaging over a billion people across more than 190 countries each year.

Today, Earth Day is recognised and supported at the highest levels of government, civil society, and international institutions. Businesses, too, are recognising it as a day to demonstrate genuine environmental leadership, engage stakeholders on shared values, and show where they stand on climate action.

The theme for Earth Day 2026,

“Our Power, Our Planet,”

reflects a fundamental shift in how environmental progress is understood. Climate action is no longer driven by policy alone, but by the collective, sustained efforts of communities, businesses, and individuals.

For businesses, this reframes Earth Day as an opportunity to demonstrate how environmental responsibility is embedded into operations, supply chains, and long-term strategy.

A high-impact Earth Day campaign has three components:

Investing in

nature-based solutions

- actions that protect, restore, or sustainably manage natural ecosystems - is becoming a central part of how businesses translate sustainability commitments into measurable impact:

The

Intergovernmental Panel on Climate Change (IPCC)

has identified NbS as among the most promising strategies for climate mitigation. Estimates suggest they could provide up to

37%

of the emission reductions needed by 2030 to stay on track with the Paris Agreement. Beyond carbon, NbS deliver what the sector calls co-benefits: biodiversity restoration, water quality improvement, soil health, flood resilience, and support for local communities and livelihoods.

A carbon-only approach to sustainability is now seen as insufficient, both by regulators (the

Taskforce on Nature-related Financial Disclosures (TNFD)

, is now pushing companies to report on nature-related impacts alongside carbon metrics) and by stakeholders who expect companies to address the full spectrum of environmental harm.

The EU's

Corporate Sustainability Reporting Directive (CSRD)

now requires companies to disclose ESG performance, including nature-related impacts. Investors are embedding nature criteria into capital decisions alongside climate metrics. Businesses that build NbS into their strategy now are getting ahead of requirements that are already arriving, rather than scrambling to catch up.

The effort to protect and restore nature faces a funding gap estimated at over

$711 billion

annually to 2030. Public funding alone cannot close it. 

The

resources

the private sector can direct toward conservation far exceed those of governments and philanthropy combined. When businesses invest in high-quality NbS, they are not just meeting their own sustainability targets, they are contributing to ecosystem protection, regeneration and restoration.

For Earth Day campaigns, NbS offer something operational efficiency measures often cannot: a visible, tangible connection to nature. 

A campaign anchored in the restoration of a rainforest, a mangrove ecosystem, or a peatland is easier to communicate, easier to verify, and more resonant with a broad audience than a percentage reduction in energy consumption.

Instead of broad intentions like "we want to support the environment," define things like:

This becomes the foundation of your campaign messaging, and the basis on which you will report results after Earth Day.

Not all nature-based projects are equal, and the quality of what you support will directly shape both impact and credibility.

Key things to look for:

Nature-based solutions can often be aligned with your industry. A construction company, for example, might gravitate towards forest restoration while a food company may find stronger relevance in regenerative agriculture.

However, highest-impact projects are not defined solely by sector fit, but by their quality, credibility, and the outcomes they deliver. 

Earthly’s

restoration,

protection, and

- each independently verified and reporting against measurable co-benefits.

With your solution in place, you need a structure that connects your business activity to environmental impact in a way that is clear and compelling.

Common approaches include:

Choose a model that aligns with your business model and audience. To automate things,

Earthly's API

allows businesses to integrate contributions directly to specific projects, giving you real numbers to build a campaign around from day one.

Data builds legitimacy, but storytelling is what makes a campaign resonate. Your campaign should answer:

For example, you could say:

"This Earth Day, we are supporting mangrove restoration in Madagascar. We have planted 1000 mangroves - protecting biodiversity, removing X tonnes of carbon from the atmosphere, and sustaining the livelihoods of coastal communities."

That is a campaign narrative with specificity, geography, and human impact - the three things that separate credible commitments from greenwashing. You could go further and commuicate specific species or people that your actions are benefitting - something Earthly helps our customers to do.

A high-impact campaign invites participation from stakeholders. You could:

Earthly provides businesses with

impact dashboards and project storytelling assets

on the customer hub that make ongoing engagement straightforward - so you are not starting from scratch on content.

Track and report against:

Share results after Earth Day internally and publicly to build trust with stakeholders. Earthly customers receive a personalised Impact Dashboard that tracks key impact data in a single, shareable page.

Not every Earth Day initiative needs to be complex or resource-intensive. While high-impact campaigns are built on strategy and long-term commitments, there is still value in simple, well-executed actions, when they are done consistently and with intention:

The key is to ensure that even smaller actions are aligned with broader sustainability goals, rather than existing in isolation.

A well-designed Earth Day campaign creates tangible value across your business:

Regulatory frameworks such as the EU’s CSRD and TNFD now require businesses to disclose and act on nature-related impacts; the cost of inaction is costly financially and reputationally. As a result, investing in credible nature-based solutions helps businesses strengthen their sustainability position.

Earthly helps responsible businesses support high-quality, verified nature-based projects, so they can meet these growing disclosure and reporting requirements with confidence

We are trusted by different companies including Deloitte, L'Oréal, Innocent, and Envision Racing at every stage of their sustainability journey to identify the right projects and solutions for their specific goals.

What makes an Earth Day campaign “high-impact?”

A high-impact campaign delivers measurable environmental and social outcomes, is built on credible nature solutions, and includes transparent reporting. 

How can businesses avoid accusations of greenwashing on Earth Day campaigns?

Be specific about your impact: name the project you support, cite the standard it operates under, describe the co-benefits it delivers, explain how outcomes are measured and reference independent verification. Working with trusted partners like Earthly can also help ensure quality and accountability.

How much should a business invest in an Earth Day campaign?

There is no fixed amount - investment typically depends on your sustainability goals, company size, and desired impact.

Is it too late to start planning a 2026 Earth Day campaign

Not at all, a credible campaign does not require months of preparation; it requires a clear commitment, a verified project, and an honest narrative. Through Earthly, businesses can get started quickly without the time and expertise required to source and assess projects independently.I

Do Earth Day campaigns need to continue beyond April 22nd?

Yes, the most effective campaigns use Earth Day as a launch point, with ongoing reporting and integration into broader sustainability efforts.
