Climate change mitigation beyond offsetting

Milkywire has created a portfolio of pioneering projects to tackle the climate crisis. Our ambition is to achieve the greatest long-term impact possible. Your company can help make this a reality.

Focus on impact, not claims

An impact-first approach creates opportunities to support pioneering solutions. For example, supporting early, high-cost carbon removal projects, research initiatives, grassroots organizations, advocacy and policy projects can all be very effective in helping to solve the climate crisis.

Milkywires’ portfolio for corporate climate contributions reflects the different needs of climate financing and supports projects in:

Permanent carbon removal

Help remove CO₂ from the atmosphere forever. It's not cheap, but we need to start developing these methods now. 

Restoring and protecting nature

Stop deforestation and help restore nature to capture more carbon while helping people.


Support high-impact renewable energy and emissions reduction projects and nonprofit organizations that fight for policy change.

Let’s make an impact!

Put your company at the forefront of solving the climate crisis.

Join forces with Klarna and other climate pioneers

Klarna has contributed over 1 million US dollars to projects selected for the portfolio in collaboration with Milkywire. The funds were generated by an internal carbon tax for 2020.

Projects supported so far:

Carbon removal

Heirloom uses a new method to sustainably capture CO2 with common minerals, with a future target cost of just $50/ton.

Human Rights Watch works to stop coal power by focusing on damage to health. They pressure decision-makers and mobilize public support to accelerate the transition away from coal.

Restoring nature

Justdiggit helps farmers in Tanzania use simple and natural methods to grow their tree stumps into mature trees.

Carbon removal

MASH uses biomass that would otherwise have been burnt in fields, contributing to air pollution, producing biochar instead to restore soils.

Carbon removal

HUSK creates biochar from rice husks which helps increase yields.


Clean Air Taskforce works on an Africa Energy and Climate Innovation Program to lay the foundations for a clean-energy future on the continent.

Protecting nature

Warsi is a grassroots organization helping indigenous groups in Indonesia get legal rights to their land to protect their forests and stop deforestation.

Carbon removal

Climeworks captures CO₂ from the air and with partners store it underground as stone.

Restoring nature

WithOneSeed is paying small-scale farmers in Timor Leste to grow, and importantly, take care of trees on their land.


Atmosfair and Kisiwa Farming Limited work to replace diesel-generated electricity on Mafia Island, Tanzania, with renewable energy from sustainable biomass.

How we select projects We have established a framework for evaluating and reviewing projects. Input is taken from an external expert advisory group to support Milkywire's mission to select the most impactful and sustainable climate projects for the portfolio. Selection criteria include the catalytic effect of donation/purchase (for example, helping bring down cost and scale up new solutions), permanence, additionality, effectiveness, verifiability, co-benefits for people and nature, and the level of risk of adverse effects to people and nature. The portfolio may include high-quality carbon credits but is not restricted to it. More information on the portfolio framework can be found here.

Beyond offsetting This portfolio is an alternative to traditional carbon offsetting solutions, which do not necessarily focus on finding the best solutions. In many cases, it’s a race to buy a set amount of carbon credits as cheaply as possible to fulfill a carbon neutrality claim. Focusing on impact instead of fulfilling an offset claim opens up the possibility to support solutions with the greatest long-term effects, wherever they are.

This approach of making contributions over claiming offsets has been recommended by numerous institutions such as Carbon market watch, WWF, New climate institute, Carbone4, Climate action network, and Gold standard.

Why did you create this initiative?

We believe companies should contribute to climate action but that there should be a greater focus on the expected effect of those contributions rather than on how many credits you bought. This portfolio reflects the different needs of climate financing and presents impactful projects in several areas, both within carbon markets and other areas.

How can companies contribute to the portfolio?

Get in touch! We are actively seeking contributions from more companies. Some of the funds brought in will support projects already in the portfolio, some may be distributed to newly identified projects.

How should companies determine how much to contribute if they are not offsetting?

We recommend setting an internal carbon tax (we can advise how) and using those funds to support climate projects. This ensures a connection between the pollution a company creates and the financial responsibility it takes for it. 

This in no way removes the obligation for companies to reduce their emissions. A good framework to follow is the WWF and BCG Blueprint for corporate climate action. Companies set emissions targets, disclose their total carbon output emissions, and implement an internal carbon tax invested into climate solutions.

A carbon tax can also incentivize companies to make reductions faster since it makes the environmental cost of their emissions clearer.

Do you claim to create the greatest possible climate impact with the portfolio?

No. That is the aim of the portfolio and what we evaluate projects on, but it is very difficult to know beforehand which projects will prove to be most impactful. We cannot evaluate more than a small share of the numerous climate projects available globally and are sure to miss out on good opportunities. But we strive to evolve the initiative, get tips and feedback and find new projects to evaluate and support.

Are you saying carbon credits are bad?

No. Carbon credits offer a structured way to support climate projects. Some credits offer very high quality, although significant shares of credits sold are cheap, low-quality ones. Even with high-quality credits, the problem lies in only focusing on buying a set amount of credits and making shaky neutrality claims rather than impact. Notably, carbon credits are not the same as offsets. Offsetting is a claim you make on the back of a credit, but there is no need to do so.

(Some of the problems with low-quality carbon credits are laid out here, here, here, and here.)

How much CO2 do you avoid/remove per dollar?

We try to find projects that get the most bang for the buck. It can mean buying carbon removals at a higher price today to help them become cheaper in the future or supporting grassroots organizations to protect forests and plant trees. We try to quantify the effect of the contributions in our reporting, but the actual implication of a tonne of carbon avoided or removed differs significantly between solutions. Some solutions avoid releasing carbon in the short term, some capture carbon and store it permanently, and some lobby decision-makers to create regulation that stops emissions in the future.
