A deep dive into the world of climate fintech with firstminute Capital

Climate fintech is a cross-cutting sector covering the intersection of climate, finance and digital technology. It includes a range of financial product innovations, applications and platforms that serve as mediums between all stakeholders to catalyse decarbonisation.

Climate change poses substantial economic and political risk to the global economy. Efforts to mitigate such risk will require a fundamental retooling of our global economy and coordinated action across public and private stakeholders. Financial services institutions play critical roles, however incumbents in banking, insurance and finance are slow to innovate. Their legacy technology infrastructure and business models don’t lend themselves to iteration and innovation.

Conversely, fintech has shown its ability to drive innovation and to reach venture scale. Financial product innovation and applied technologies such as big data, artificial intelligence, distributed ledger technologies make capital availability, data gathering and processing much faster, transparent and cost effective. As a result, they have important roles as enablers and disruptors within climate change.

The climate transition requires financial sector innovation in multiple areas:

  • Facilitating the shift of investment dollars towards renewable energy and away from oil & gas

  • Tools for tracking emissions and changing behaviour at the business/consumer level

  • Financing of new infrastructure for energy and transport

  • Management and mitigation of climate risks

Market size

Financing requirements for the transition to a low-carbon economy and for meeting the objectives of the Paris Agreement (limit the global temperature rise to below 2C from pre-industrial levels, and pursue efforts to limit it to 1.5C) are estimated to be in the range of $3–$5T of investment per year globally over the next 30 years for the decarbonisation of 10 sectors representing 75% of global emissions. This is an increase of five to eight times from the current market for climate finance which is estimated at $600B.

Additionally, climate finance needs are expected to not be linear over the next three decades as a lack of urgent action today will result in higher future investments. In this framework, policy and regulatory changes will play a key role in driving change in the financial services ecosystem.

The fintech market represents a small percentage of the overall financial services sector, however it is growing rapidly and driving change across the industry. The global fintech market is projected to grow steadily at a compound annual growth rate (CAGR) of about 23% reaching a market size value of $324B by 2026. Climate fintech is set to play a major role within a fast-growing space.

Business models

A wide range of business models across multiple verticals are emerging, applying a mix of already proven technologies.



The overall impact of consumers surpasses in scale the actions of the largest investors, resulting to be one of the strongest catalyst for sustainable change.

The volumes of mobile payment transactions reached $51T in 2019, an increase of over 28 times from six years ago. The convenience of digital payments has enabled adjacent sustainable solutions tied to consumer spending tendencies. Spending behaviour is indeed strongly tied with carbon emissions, and the conscious consumer needs to be provided with tools to make sustainable decisions.

Innovation efforts to help citizens transact in ecologically-minded ways present great opportunities across industries: most airline carriers today present carbon-offsetting options, ecommerce marketplaces offer eco-friendly packaging and shipping, while digital consumer payments channels such as Alipay and WeBank are developing ways to encourage consumers to adopt green practices via their mobile payments platforms.


Within the financial services ecosystem, retail and commercial banks are uniquely positioned to foster sustainable practices by integrating educational solutions and financing mission-driven projects.

  • Retail Banking. Retail banking has faced a fundamental wave of disruption in the last decade due to the rise of convenient and accessible solutions developed by challenger banks. Adoption of such platforms skyrocketed thanks to attractive personal finance offerings including low rates, high user experience and ample services range. The agility of neobanks combined with their wide adoption across the young generations places them in a unique position to develop ethical, transparent and simple products which have a positive environmental impact. These include solutions such as decarbonisation tracking of shopping, automatic offsetting of purchased items and tree planting credit cards.

  • Commercial Banking. Applications of commercial banking for decarbonisation revolve around credit analysis and project financing for renewable energy, electrification and resource efficiency businesses. Banks innovating in the space leverage AI to parse alternative data to help design eco-friendly lending models and issue green bonds.


Debt financing plays a key role in facilitating investments and enabling projects. The majority of large infrastructure projects are financed with debt rather than equity. In the renewable energy sector, the deal structuring is driven by tax incentive structures and the digitisation of this process has benefited from several fintech solutions. These include new lending structures such as P2P lending for capital accessibility, AI and big data models for credit analysis and Blockchain-based platforms for transparent and intermediaries-free green loan issuance.


Sustainable investing is an established category and assets under management are growing steadily. Global ESG assets are on track to exceed $53T by 2025. The growth of ESG investment is driven by multiple factors, including regulatory pressure, increased sustainability-related education of the population, shift of capital to the younger generation, decreasing fees and superior returns performance, with the majority of ESG funds outperforming the wider market over the last decade.

Asset managers and owners are leading the movement presenting $100T in AUM as members of the Principles of Responsible Investment (PRI), with many also signing the Net-Zero Asset Owner Alliance. This shift in investment strategy implies a strong climate impact, with moving a pension to a more sustainable fund being 27 times more effective in reducing carbon footprint than being vegan and not flying combined.

Sustainable investing is increasingly facilitated by the proliferation of enabling platforms, including investment marketplaces for average consumers, robo-advisors, AI-driven software adopted by wealth managers and financial institutions to optimise portfolio management for carbon accounting.

Risk management

Risk management is at the core of investing, with risk being correlated to financial reward. In today’s ever changing world, dividends derived from GHG intensive activities are offset by substantial sustainability risks. These include events such as policy changes, physical climate-induced destruction and financial penalties for unethical business behaviour.

In this context, climate risk analysis does not imply fighting climate change but rather ensuring the maximum return on investment despite climate change. This usually is achieved by implementing green practices such as adopting more net-zero business practices, investments into renewable energy and divestments into GHG-intensive activities.

The emergence of Big Data has allowed for superior collection, processing and analysis of risk data. The collection of large data gathered from edge computing devices such as sensors and satellites and from more traditional technologies such as Cloud and public databases has fostered new enriched datasets for processing and insights extrapolation. Risks associated with floods, rising sea level, deforestation, wildfires can be automatically factored into the risk analysis of projects and investments, ultimately impacting the allocation and cost of capital.


Green trading practices can be divided into two main categories: carbon trading, which includes emissions exchanges, and energy trading, which involves the exchange of distributed energy using smart grids.

  • Carbon Trading. Emissions and carbon trading has become an established practice to put a price on carbon emissions and pollution and incentivise projects which offset such emissions. Cap-and-trade emissions trading schemes allow governments to allocate allowances to corporations, who can in turn buy and sell these on the open market. To keep the planet to 1.5C, all future net emissions of carbon dioxide from 2018 need to be limited to 570 gigatons. At the current pace, the world would exceed the target by 2031. Carbon markets play a fundamental role in achieving this global objective.

  • Energy Trading. Power grids have traditionally been centralised systems whereby utilities control the flow of electricity based on demand of passive consumers. The proliferation of renewable energy sources has induced more flexible and decentralised energy infrastructures, helping to avoid line loss effects caused by the dissipation of energy across long transmission lines. The resulting network transformation from a centralised grid to a network of local microgrids has contributed to shifting the management responsibilities back to local communities. Decentralised energy systems are projected to account for roughly 25% of the energy market by 2050.

Interconnected decentralised microgrids are known as smart grids, where electricity flow is decided using technological solutions such as smart meters, smart appliances and renewable energy sources. Innovation around smart grids present a lot of promise, with improving the US electricity grid by 5% being equivalent to eliminating the fuel and carbon emissions of 53M cars.

Data analytics and reporting

As the flow of capital increases towards decarbonisation, accurate carbon data and reporting is pivotal ensuring systematic financial supervision and providing actionable insights to private and public stakeholders. Spending on ESG data is projected to approach $1B this year, and it has grown at an annual growth rate of 20%. ESG data & reporting for the investment sector alone is projected to reach $2.54B by 2031.

Such growth is facilitated by international efforts to align climate monitoring and taxonomies between corporates and states within agreed frameworks. In this context, the Task Force on Climate-related Financial Disclosures (TCFD) and the Partnership for Carbon Accounting Financials (PCAF) play important roles: the former providing high-level principles for climate-related risks and opportunities and the latter developing an accounting tool to monitor financed emissions.


Insurance companies are the largest group of asset owners on the planet after pension funds with over $30T in AUM. They play a fundamental systemic rule as risk managers, risk carriers and investors. However, they are regularly impacted by the climate-induced events, with climate change being recognised today as a severe threat for the insurance industry due to the risk imposed to their assets (such as real estate) and, more importantly, due to the increased number of policy holders’ claims.

As risk managers, insurance companies have access to the latest climate models which are used as inputs to their catastrophe risk models and loss-prevention systems, reducing costs of labour and maximising speed of claims payments. As incumbents in the space are usually capable to build their own internal systems, a new wave of fintech startups has started developing systems targeting small and medium-sized insurance companies to provide their own technology services.

Crypto and Blockchain

Decentralised technologies have the potential to foster sustainability-related changes by exploiting the benefits of blockchains, such as immutability and transparency. Nevertheless, concerns around Bitcoin’s carbon footprint have made headlines as the proof-of-work consensus algorithm requires large amounts of energy to sustain the mining process. Despite the controversy, blockchains are considered vital enablers in tracking carbon emissions and consumptions. Firstly, they allow smart energy distribution to take place, verifying how utility companies have redistributed their overproduction of energy, all while reducing costs and increasing trust among stakeholders.

Secondly, banks have already started to implement blockchain technology to help with green bonds issuance by creating smart contracts with built-in encryption features, making a transfer of value virtually fraud-proof. Thirdly, new projects are being developed, such as AirCarbon Exchange, focusing on securitising carbon credits into fungible and tradable securities with transparent pricing and real-time settlements.

Finally, recent decentralised autonomous organisations, such as Klima DAO, have started obtaining traction by accelerating the price appreciation of carbon assets, forcing companies and economies to rapidly adapt to low-carbon technologies and carbon-removal projects.

Market landscape

According to New Energy Nexus, a December 2020 survey identified 250 climate fintech companies globally. The climate fintech market is in its early stages and growing, with over 75% of companies having raised USD $10M or less. The ecosystem is ripe for investment and further growth.

For climate fintech, increasing data availability and policy changes are creating space for growth, however the taxonomies, data standards, and national and industry policies are still being established. This creates market uncertainty but is a significant opportunity as coordination increases to define stronger market structures.


Among the data sample considered, the highest number of exits, with these having been acquisitions, has been recorded in the risk analysis and management space. Examples:

Active Investors


  1. The rules of the game are still being defined for reporting and tracking (TCFD, SASB, emissions trading specs, etc), introducing uncertainty and “a bit of a wait-and-see” dilemma for entrepreneurs. (Bruno Werneck de Almeida)

  2. Public policy and incentives need to continuously evolve to mobilise the maximum possible private sector capital towards climate-aligned instruments

  3. Over-reliance on carbon offsets, while standards or verification for offset quality are not yet available, increases the risk of green-washing

  4. Solutions focused on consumer education and choice can be meaningful as a mechanism for education and engagement, and can increase the pace of change by increasing pressure on institutions. However, they have a lower and less direct impact compared to business solutions and may divert resources from more powerful climate change fighting technologies

  5. GHG are not yet fully priced into both the real economy and markets, leading to cheap distribution of non-green assets
