Planting trees for the climate: effective measures for companies

For companies, planting trees is far more than just a nice gesture. It is a visible and incredibly effective climate protection measure that everyone understands. If trees are understood for what they are – natural carbon filters and air conditioning systems for our planet – companies can communicate their commitment authentically to the outside world. This creates trust, both with customers and partners.

Why planting trees for the climate is an investment in the future

For more and more companies, planting trees is becoming a central component of their sustainability strategy. This is no longer just a matter of putting on a “green” mantle. Rather, it is a strategic decision with benefits that go far beyond pure environmental protection.

Just think of trees as the lungs of our planet. They breathe in carbon dioxide (CO?) – one of the most harmful greenhouse gases – and convert it through photosynthesis into the oxygen we all need to live. They store the carbon safely in their wood, branches and roots.

The measurable impact of forests

The enormous importance of forests for climate protection can even be expressed in figures. The German forest alone is a gigantic carbon store. It relieves our atmosphere of around 62 million tons of carbon dioxide every year. This corresponds to around 7% of Germany’s total greenhouse gas emissions.

Getting involved in reforestation projects is therefore a direct way for companies to make a tangible contribution. It’s a tangible measure that is easy to understand and comprehend – for your own employees as well as for customers and business partners.

Planting trees is one of the most understandable and emotional forms of climate protection. It creates a direct link between entrepreneurial action and a positive, visible impact.

However, this approach is far more than mere compensation. A cleverly planned reforestation initiative is a decisive step towards truly anchoring sustainability in the company and living it credibly.

The advantages for companies are obvious:

• Strengthening the brand: Visible commitment to climate protection sets a company apart from the competition.
• Greater customer loyalty: People increasingly prefer brands that demonstrably take responsibility for the environment and society.
• Better employee retention: Sustainability initiatives make employees proud and strengthen their identification with their employer.

Ultimately, strategically planting trees for the climate is an investment that pays off twice over – for our planet and for the long-term success of your own company.

So, how exactly do trees actually do this with CO?

Quite simply, trees are the most hard-working climate protectors on our planet. Their superpower is a process that we all learned about at school: photosynthesis. But don’t worry, this isn’t going to be a dry biology lesson.

Just imagine a tree breathing in the carbon dioxide (CO?) that is harmful to us and is floating around in the atmosphere.

With the help of sunlight, water and a few nutrients from the soil, the tree cracks the CO? molecule. It uses the carbon (the “C”) as a building block to grow, and the pure oxygen (the “O?”) it releases back to us. This is precisely why planting trees has such a direct and tangible effect on the climate.

From gas in the air to solid wood

The carbon that the tree has absorbed does not simply vanish into thin air. It becomes firmly bound and is transformed into wood, bark, branches and leaves. A large proportion even migrates into the roots, which anchor the tree firmly in the ground. In this way, an invisible greenhouse gas becomes a solid, stable structure.

A single tree thus becomes a living vault for carbon. An entire forest? A huge, underground network that stores carbon not only in the trees themselves, but also in the soil, in humus and fungal networks. This makes forests one of the most important carbon reservoirs on land.

Every tree functions like a biological CO? pump. It actively sucks carbon out of the atmosphere and stores it safely in the ecosystem for decades, sometimes even centuries.

But not all trees are the same. There are real CO? champions among them. Fast-growing species such as the tree hazel can build up a lot of biomass in a very short time and bind significantly more carbon than slow-growing trees such as the columnar oak. To drive this rapid growth, a single hazel tree can consume over 7,000 liters of water in just four months – and store a considerable amount of carbon in the process.

Why young forests are often the more diligent climate protectors

An old, untouched primeval forest is an invaluable treasure for biodiversity, no question about it. But when it comes to pure carbon sequestration, young, growing forests often have the edge. The reason for this is actually quite simple: young trees are in a growth spurt. They build up biomass like crazy and therefore have a huge “appetite” for CO?

The carbon bond can be divided into phases:

• Young forest: Maximum CO? absorption because the trees grow rapidly and produce lots of wood and roots.
• Mature forest: CO? uptake slows down. The forest settles into an equilibrium in which absorption and release through decaying wood are in balance.
• Ancient forest: Acts primarily as a huge store for carbon that has been sequestered for centuries.

Precisely because the growing conditions are so crucial, it makes perfect sense to support reforestation projects in places where trees grow particularly quickly and well. Take a look at why we plant some of our trees in the tropics to achieve maximum impact for the climate.

Science agrees: a freshly planted tree starts working immediately, but of course it takes some time. Studies show that, on average, a tree needs around 14 years to offset the emissions caused by its planting and care at the beginning. After that, however, it makes a real net positive contribution to the climate over its entire lifespan.

Choosing the right trees for maximum climate impact

In order for planting trees to really make a difference for the climate, we need to ask ourselves a crucial question: Which tree should actually grow where? It’s not enough to simply stick a seedling in the ground. The clever choice of tree species and the right location is the absolute key to a long-term and measurable effect.

A crucial point here is the origin. Native tree species are the true local patriots – they are perfectly adapted to the local conditions. This means that they cope much better with the regional climate, the soil and the local pests. This makes them much more robust and massively increases the young forest’s chances of survival.

The following photo shows it symbolically: the foundation stone for a healthy forest is literally in our hands. Careful selection is the be-all and end-all for the success of reforestation projects.

Mixed forest instead of monoculture

At least as important as the origin of the trees is their diversity. A healthy forest is always a mixed forest. Monocultures, i.e. huge areas with only one type of tree, are extremely vulnerable. If a pest or disease spreads, it can destroy the entire stand. A real disaster.

A colorful mixed forest, on the other hand, is like a strong immune system.

• Greater resilience: Different tree species react very differently to stress, be it drought or pest infestation. If one species fails, the others step into the breach.
• Promoting biodiversity: Mixed forests are a paradise for countless animals, insects and microorganisms. They provide habitat and food.
• Improved soil health: The different roots loosen the soil and ensure a better nutrient cycle. In the end, all trees benefit from this.

A stable mixed forest is not only a more effective carbon sink, but also a guarantee for a resilient ecosystem. It is the best insurance against the uncertainties of climate change.

To make the selection easier, we have compared some native tree species and their characteristics for climate-appropriate forest conversion. This table shows which species cope particularly well with drought, grow quickly or have a high ecological value.

Comparison of native tree species and their climate resilience

This table compares common native tree species in terms of their suitability for climate-appropriate forest conversion, based on drought tolerance, growth and ecological benefits.

Tree species	Tolerance to drought	Growth rate	Ecological value for biodiversity
English oak	Medium to tall	Slow to medium	Very tall
European beech	Medium (susceptible to stress during extremes)	Medium	High
Sessile oak	Tall	Slow to medium	Very high
Hornbeam	Medium	Medium	High
Winter lime tree	Medium	Medium to fast	High
Bird cherry	Medium	Fast	Very high
Field maple	High	Medium	High

The table makes it clear that there is no one perfect tree species. A clever mixture of robust pioneers such as the sessile oak and ecologically valuable species such as the bird cherry is often the best way to create a sustainable forest.

Location and CO? storage capacity

The location is decisive for how much carbon a tree can ultimately bind. Current estimates assume that one hectare of forest can store an average of around 6 tons of CO? per year. But beware: this is only an average value. The actual performance depends heavily on factors such as light, water, soil quality and the age of the forest. You can find out more about the complex interrelationships of CO? storage in forests at wald.de.

Projects in Germany have the great advantage that they directly strengthen our domestic ecosystems and are easy for us all to understand. International projects, especially in the tropics, often score points with faster growth and therefore faster carbon sequestration. No matter where: the quality of the project is always decisive. The selection of climate-resilient species and loving, long-term care are the foundation for every success.

How to recognize greenwashing and project risks

When a company plants trees for the climate, it sends out a strong, positive signal. But to be honest, the path from good intentions to real, measurable impact is often a rocky one. You have to look relentlessly at the challenges so that you don’t end up disappointed or have thrown money down the drain.

Even the best reforestation projects are not immune to everything. Climate change, which we are trying to combat, does not stop at young forests. Extreme droughts, pest infestations or devastating forest fires can undo years of work and massively jeopardize the success of a project.

Seeing through the greenwashing dilemma

Greenwashing is more than just an unattractive marketing term – it destroys trust in genuine, honest climate protection. Dubious providers often throw around unrealistically cheap prices and vague promises. Their focus is usually only on the sheer number of trees planted, while the much more important long-term factors are completely ignored.

Pay attention to these warning signals:

• Lack of transparency: Where exactly are the trees supposed to grow? Who will look after them? Reputable partners will provide you with clear answers and even geodata.
• No long-term care: A tree is planted, but it is far from being saved. Without several years of care – i.e. watering and protection from wild animals – many seedlings do not survive the first year.
• Focus on quantity, not quality: planting a million trees that are dead again after a year does exactly nothing for the climate. What matters is the survival rate and how much CO? is actually absorbed in the end.
• Lack of certificates: Independent seals such as the Gold Standard or Plan Vivo ensure that projects meet high environmental and social criteria.

Seriously planting trees for the climate means taking responsibility for the entire life cycle of a tree. From growing the seedling to securing the forest for decades to come. Anything else is just an empty gesture.

The inconvenient truth about our forests

It is a paradoxical and quite alarming development: even our established forests here in Germany are suffering massively from climate change. They are no longer the safe carbon sink we always thought they were. An analysis by the Öko-Institut has revealed a shocking truth: between 2017 and 2022, German forests became a net source of CO? on average. Instead of absorbing CO?, it released around 25.6 million tons of CO? equivalents every year, mainly due to dying trees after drought and pest infestation. You can read the whole worrying analysis at the Öko-Institut.

This fact makes it abundantly clear how critical it is to choose the right partner and project location. It’s about investing in projects that are designed for climate resilience – by planting robust mixed forests and in locations where the conditions are right and the risks are manageable. Only then will your commitment make a lasting, positive contribution to our planet.

Your practical guide for tree planting projects

So, enough theory, now it’s time to get practical. How can you as a company get started and ensure that your commitment really bears fruit? The path to a successful tree planting project starts with choosing the right partner and a clear strategy.

There are various ways to get involved. For example, you could enter into a direct partnership with local forestry offices or the city administration. This has the advantage of regional visibility. However, it is often more efficient to work with specialized organizations that operate internationally.

These partners have the necessary expertise and infrastructure to implement projects where trees grow particularly quickly and the climate impact is greatest. And they often also create social and economic benefits for the local people.

Choosing the right partner

The choice of partner is perhaps the most important decision. It determines how credible and successful your commitment really is in the end. A good project partner works transparently, has experience and can provide tangible proof of the impact of their work.

You can use this small checklist to check how serious and effective a project is:

• Transparency and reporting: Do you receive clear information about the location, tree species and maintenance? Reputable providers supply regular updates and often even geodata so that you can track everything.
• Long-term care: Ask specifically. Does the price include several years of care for the small seedlings? A tree that is only planted in the ground but never cared for has little chance of surviving.
• Holistic approach: Does the project look beyond the scope of pure carbon sequestration? The creation of jobs or the promotion of biodiversity are real quality features.
• Certification and standards: Does the partner work according to recognized standards such as the Gold Standard or Plan Vivo? Such seals are a guarantee that strict ecological and social criteria are adhered to.

You don’t recognize a serious project by the cheapest price per tree. You can recognize it by the highest guarantee for a long-term, positive effect. The investment must cover the entire chain: from breeding and planting to years of care and protection of the new forest.

Communicate credibly without greenwashing

Your commitment is valuable – and you should talk about it. Honest and transparent communication strengthens your brand and creates trust. The only important thing is that you don’t fall into the greenwashing trap.

This is how you communicate your commitment authentically:

1. Talk honestly about your motivation: explain why you decided to plant trees for the climate and what you want to achieve.
2. Give specific details: Instead of just saying “We plant trees”, say: “We support a certified reforestation project in [country/region] to plant [number] climate-resilient trees.”
3. Make the impact visible: Use your partner’s reporting to report on progress. Show pictures, share stories from the people on the ground and make the positive impact tangible.

By choosing a trustworthy partner and communicating your commitment transparently to the outside world, you make your investment in climate protection measurable, comprehensible and, above all, effective. This turns a good intention into a real success story for your company and our planet.

How trees become a firm anchor of your climate strategy

Let’s make one thing clear: planting trees for the climate is a valuable and, above all, visible measure. However, it only unfolds its full power when it is part of a larger, well-thought-out strategy.

The most effective climate protection for any company always starts with the direct avoidance and reduction of emissions in its own operations. See reforestation projects for what they are: an absolutely sensible and necessary supplement to offset the residual emissions that simply cannot be avoided in the short term. A holistic approach is the key to success here.

An investment in forests is an investment in a future worth living. It is a strong signal that your company is actively taking responsibility and looking beyond its own backyard.

A first, decisive step in identifying these unavoidable emissions in the first place is a valid carbon footprint. Here you can find out how to draw up a well-founded carbon footprint for your company and thus lay the foundations for truly effective climate protection measures.

Ultimately, such an honest approach not only motivates your own team, but also strengthens the trust of your customers and partners. It shows that your commitment is not just a façade, but well thought out and designed for long-term impact.

The most burning questions on the topic

When companies think about planting trees for the climate, the same questions come up again and again. We have collected them and provide short, practical answers that really help.

How many trees do I need to plant to make my company climate-neutral?

Unfortunately, this question cannot be answered with a simple number. Achieving climate neutrality just by planting trees is a multi-layered goal. In the end, it is not just the number of trees that counts, but how much CO? the entire project demonstrably binds over decades.

The first rule is always: first reduce your own emissions wherever possible. Planting trees is then the ingenious second step to offset the emissions that cannot (yet) be avoided. Certified projects help to calculate the necessary compensation in a clear and comprehensible way.

Climate neutrality always starts with reduction. Trees are the powerful second step towards offsetting emissions that are still unavoidable today.

Is it better to plant trees in Germany or abroad?

Both have their justification and are not mutually exclusive. Projects in Germany are great for directly strengthening our native ecosystems and promoting local biodiversity. For partners and customers, the commitment is often more tangible and easier to understand.

On the other hand, trees in the tropics often bind CO? much faster because they grow all year round. Many international projects also create targeted jobs and support local people. No matter what you choose: It is important to have a reputable partner who focuses on climate-stable mixed forests and long-term care of the trees.

What does it cost to plant a tree?

Prices vary greatly here – from under €1 to over €30 per tree. However, you should be wary of extremely cheap offers. These often only cover the price of the seedling itself, nothing more.

Good, serious projects consider the entire life cycle of the tree. The following points are therefore also included in the costs:

• Growing the young seedlings in the nursery
• Professional planting in the right place
• Care and protection in the first, critical years
• Long-term monitoring to ensure the success of the project

So price should never be the only criterion. Invest in the effect, not just the planting.
