Climate Transformation Fund
A best-practice alternative to carbon credits: a curated portfolio of high impact projects driving global net-zero
Designed for sustainability leaders
Launched in 2021, the Climate Transformation Fund (CTF) is a premier solution for companies committed to going beyond emission reductions. This portfolio of high-impact, innovative projects is designed to accelerate global net-zero goals. Aligned with SBTi’s Corporate Net-Zero Standard, the CTF aims to maximize long-term CO₂ reduction or removal per dollar spent. It focuses on innovative CDR technologies, effective nature restoration, and leveraging policy to drive large-scale decarbonization. These efforts are supported by three critical pillars:
Durable carbon removal
Decarbonization
Protecting and restoring nature

Climate Transformation Fund pillars
The Climate Transformation Fund encompasses a wide array of projects, each addressing different themes and approaches. We focus on three main pillars, which support the portfolio's overall framework. Within each pillar, various projects pursue similar goals through different methods.
Durable carbon removal (CDR)
CDR is one of the most crucial solutions to reach and maintain net-zero emissions and limit global warming. To counterbalance fossil emissions from the long carbon cycle, the carbon removed needs to be stored durably. While solutions for durably removing carbon are still nascent, pre-purchasing carbon removal from startups can help kickstart the sector, making it an affordable and climate-relevant solution in the future. When credits or certificates are bought, they will be retired, meaning they cannot be resold and will not be counted as financial instruments.
Ocean CO₂ capture: Electrochemistry
Enhanced rock weathering (ERW)
Woody biomass burial
Bio Energy Carbon Capture and Storage (BECCS)
Direct Air capture with storage (DACs)
BiocharHigh additionality: Projects are evaluated on their ability to remove tonnes that wouldn't occur without funding.
Potential: Projects are assessed for their potential to become a significant solution to the climate crisis.
Catalytic effect: Projects are prioritized if donations or purchases lead to greater growth of the method beyond just the purchased tonnes.
Co-benefits: Projects are given higher priority if they benefit people in poverty or help ecosystems beyond carbon storage.
InPlanet operates in Brazil as the first Enhanced Rock Weathering startup solely focused on the tropics. They spread silicate rock powder under ideal soil and climate conditions, promoting rapid weathering and carbon capture. The carbon is stored in soil leachates, waterways, and ocean sediments. Key co-benefits include the restoration of degraded soils, improved food nutrition, and reduced reliance on conventional chemical inputs in agriculture. InPlanet conducts rigorous measurements, from laboratory to field, to assess the net carbon removal effectiveness of rock spreading in various agricultural contexts.
Decarbonisation
There is a need to support efforts that can reduce emissions. Change is not happening fast enough on its own. A high-impact way of accelerating emission reductions is by supporting effective organizations influencing decision-makers to implement more ambitious climate policies. Another way is to support innovation in new fossil-free energy solutions in cases where market forces are not providing the necessary funds.
Accountability
Renewable energy
Enabling environmentCo-benefits: Projects that benefit marginalized communities, provide social co-benefits, or aid ecosystems beyond carbon storage are prioritized.
Climate impact: Projects are assessed on their potential direct or indirect effect on avoided emissions.
High additionality: Projects unlikely to occur without support are prioritized, avoiding those similar to already funded initiatives.
Catalytic effect: Projects are evaluated for their potential to scale and create impact beyond their immediate scope, especially as pioneering solutions.
Human Rights Watch (HRW) is an international non-governmental organisation that advocates for human rights, including the right to a healthy environment, and holds governments and other entities accountable for human rights abuses. HRW's work in the context of fossil fuels involves investigating and exposing their negative impacts on human rights and health in affected regions, advocating for governments to transition to cleaner energy sources, and engaging in global advocacy efforts to better regulate the industry, end public financing for it, and prevent new or expanded fossil fuel projects from coming online. HRW’s goal is to limit climate-related devastation on people and communities with an immediate and fair phasing out of fossil fuels.
Nature protection and restoration
Protecting and restoring nature is of paramount importance for addressing climate change. Deforestation and forest degradation result in substantial carbon emissions as forests are destroyed. Preserving the carbon stored in existing ecosystems and restoring carbon to areas that have lost it are critical steps in mitigating climate change. These actions not only help reduce greenhouse gas emissions but also have significant co-benefits for both human societies and biodiversity.
Tenure security
Restoration
Farmer managed natural regeneration (FMNR)
Community forest management (CFM)Climate impact: Projects that protect or increase carbon stocks in nature.
Catalytic effect: Projects that can be replicated, spread to new communities, or inspire innovative solutions are preferred.
Track record: Projects with a strong history of successful implementation outcomes are prioritized.
Co-benefits: Projects are prioritized if they benefit marginalized communities, contribute to environmental justice, or help ecosystems beyond carbon storage.
The Ceibo Alliance, an Indigenous-led organisation operating in the Upper Amazon across Ecuador, Colombia, and Peru, empowers Indigenous communities to combat deforestation and protect vital carbon sinks within their territories. A key element of their strategy involves mapping and monitoring forests, where they support community land patrols in detecting and deterring activities that threaten the rainforest in real time. They also gather evidence of these illegal activities, leveraging legal channels to stop future encroachments and protect their territories.
Durable carbon removal (CDR)
Namibia
PyroCCS pioneers sustainable industrial biochar carbon removal in the Global South, deploying its own low-cost, robust, pyrolysis systems powered by renewable energy and backed by a digital measurement and reporting solution. These plants efficiently convert invasive acacia bushes in Namibia, a significant threat to the savanna ecosystem, into high-quality biochar, while providing critical employment in regions with high youth unemployment rates. PyroCCS's scalable technology, which they are also offering as a solution to other project developers, not only captures carbon but also supports local agricultural and environmental recovery as well as food security.
Decarbonisation
Australia
Beyond Zero Emissions (BZE) is an independent think-tank working on net zero pathways for Australia, highlighting how the green transition benefits the economy. The CTF provides core support to BZE to strengthen its organisational capacity, research, and advocacy work.
Nature protection and restoration
Indonesia
Planète Urgence is a non-profit organisation dedicated to environmental conservation and community development, with a notable presence in Indonesia. Their work spans various critical areas, including the restoration of mangroves and coastal trees, fostering sustainable aquaculture practices, and enhancing the economic well-being of local communities. The supported project is specifically tailored to combat the ecological harm caused by shrimp farming and deforestation in the fragile ecosystems of Borneo's Mahakam Delta and Adang Bay. This multifaceted initiative includes essential components such as environmental education, the establishment of community mangrove nurseries, and the provision of training in sustainable aquaculture practices. Through these concerted efforts, Planète Urgence aims to not only mitigate the environmental damage but also empower the local communities to adopt more sustainable livelihood practices.

Why a portfolio approach?
By supporting the Climate Transformation Fund, companies contribute to a diverse range of solutions needed to combat climate change. This increases the likelihood of reaching global net-zero and reduces investment risk by spreading contributions across various high-impact projects.
How do you find projects?
Annually, we invite interested projects to apply for our Climate Transformation Fund by issuing a call for proposals. We select about 30 projects that best meet our criteria for maximum impact. Our latest call attracted over 1,000 applications, with a selection rate of about 2%.
Why choose this approach over carbon credits?
Choosing Milkywire's curated portfolio offers a diversified, scientifically-backed selection of projects, unlike direct carbon credit purchases which often lack this breadth and strategic alignment. It also mitigates the risk of greenwashing claims, demonstrating a commitment to supporting the most effective climate projects.
Do you sell carbon credits or offsets?
The CTF does not issue carbon credits or claim offsets. Our focus is on long-term impact. This can involve purchasing carbon removals at higher prices today to make them cheaper in the future or supporting projects to protect forests and plant trees. We quantify the impact of contributions in our reporting, but the actual effect of a tonne of carbon avoided or removed varies between solutions.
Why focus on durable carbon removal (CDR)?
Durable carbon removal involves technologies and projects that remove CO₂ from the atmosphere and store it for long periods (hundreds to thousands of years). With over 90% of global GDP committed to net-zero, durable carbon removal will be essential to meet these targets. However, the CDR market is still developing and requires significant funding to meet future demand.
What is a credible internal carbon fee?
A credible carbon fee varies, but one approach is to base it on the cost of durably removing and storing CO₂ from the atmosphere, which is currently several hundred US dollars per tonne. The New Climate Institute suggests 100 euros per tonne as a credible level for corporate climate contributions. This can differ based on company needs. Contact us for help in determining an appropriate carbon fee for your organization. Read more on setting an internal carbon fee.
How do we communicate the impact funded through Milkywire?
Transparency is key. Instead of claiming to offset a specific number of tons, an internal carbon fee allows you to tax your own emissions, providing an incentive to reduce them, and explaining where the funds are spent. For example, you can learn more about how Northzone communicates their impact on the Northzone sustainability page.
