II Whitepaper: Strategies to scale private
and blended climate finance for a just green
transition
The urgency for mobilising climate finance has never been greater. At COP29, participating nations set
ambitious goals for transferring climate finance from developed to developing countries. COP30 in Brazil will
be critical in transforming these commitments into actionable steps that align with the Paris Agreement
objectives. We have the pledges; now it is imperative to implement the right financial mechanisms to
facilitate the flow of climate finance.
The private sector plays a pivotal role in achieving these targets, yet substantial barriers to unlocking private
climate finance remain. During London Climate Action Week, a roundtable convened high-level stakeholders
to explore strategies for increasing private climate finance mobilization. This whitepaper synthesises insights
and recommendations from the roundtable, presenting strategies to effectively mobilise climate finance for
meaningful climate action and a just green transition.
It serves as a supplementary document to the previously published whitepaper private climate finance
released post Climate Week in New York last year:
I Whitepaper on private climate finance.
1. Define, integrate, and scale private and blended climate finance
To effectively measure private climate finance, establishing a clear definition is essential. It is imperative to
recognise that climate risk is inherently a financial risk, necessitating better integration of climate
considerations into mainstream financial decision-making rather than treating them as niche concerns.
Impact and good returns can be complementary rather than opposites, but this requires a shift towards
longer-term horizons and the liberty for institutions to explore strategic allocation of portions of their
portfolios.
Blended climate finance has so far not achieved the scale required, largely due to structural inadequacies,
complexity, lack of exit strategies, difficulties in securing catalytic capital, and challenges relating to
governance and transparency. It is crucial to rethink how blended finance mechanisms are structured and
deployed to attract private investment.
Case: Nordic collaboration at its best: IMCA
The Investment Mobilisation Collaboration Alliance (IMCA) is an example of a successful multistakeholder
initiative linking Nordic countries, development banks, and private investors through a central Secretariat
operated by the World Climate Foundation.
IMCA enables countries to pool public development funding to de-risk and attract private capital into
emerging and developing markets, demonstrating the power of collaborative finance and crowding-in. This
approach has already mobilised hundreds of millions of USD in private investment, directing capital to
underfunded regions and sectors. Since its launch at COP28 in 2023, IMCA has initiated three innovative
finance windows, with a fourth set to launch at COP30:
•
The BFET window supports climate mitigation in JET-P countries
•
The AFW focuses on climate adaptation
•
The GVCA promotes localisation and sustainability in Africa’s energy transition value chains
•
The new Adaptation Finance Window for Africa set to launch soon.
