Tokio Marine, Japan’s largest property and casualty insurance provider, has taken a bold step into the future of sustainable finance with the launch of its new green insurance unit—Tokio Marine GX (TMGX). This strategic move positions the company at the forefront of global efforts to support the energy transition, with TMGX targeting $1 billion in revenue by 2030 and aiming to capture 10% of the projected $10 billion global green insurance market.

TMGX will specialize in offering insurance and advisory solutions tailored to businesses transitioning to low-carbon operations. These will include high-risk sectors such as green hydrogen, small modular nuclear reactors, floating solar, cement, and shipping—industries where traditional insurance coverage has often been limited or entirely absent. By addressing the unique risks associated with these sectors, TMGX hopes to unlock the financing and de-risking needed to accelerate global decarbonization.

At the core of TMGX’s offering is its ability to provide up to $500 million in coverage for a single risk, making it one of the most robust and flexible options in the green insurance landscape. This high-limit coverage is particularly vital for capital-intensive decarbonization projects that require comprehensive risk mitigation to secure investor confidence and affordable financing.

Fraser McLachlan, who heads both GCube, Tokio Marine’s renewable energy arm, and the newly established TMGX, emphasized the importance of innovation in green insurance. “We’re going to rip up the rule-card a little bit here,” McLachlan stated. “We’re going to look at some new technologies, we’re going to look at more sophisticated ways of being able to risk transfer business.” His comments reflect a growing sentiment in the insurance industry that legacy models no longer meet the demands of rapidly evolving energy technologies and financing structures.

In a landscape where conventional insurance products often fall short, TMGX is developing creative solutions like tax credit insurance. This new offering is designed to unlock project financing by covering the risk of losing tax credits—a critical revenue stream for many green infrastructure projects. According to McLachlan, tax credit insurance is a triple-win: “Lenders love it as it transfers their risk; we like it, we’re getting a premium for a risk we’re comfortable with; and it allows the project to be financed at more equitable terms.”

TMGX builds on the foundation laid by GCube, which currently generates $200 million in annual revenue and employs a 50-person team specializing in renewable energy insurance. Both GCube’s revenue and team are expected to double in the coming years as part of Tokio Marine’s broader strategy to scale its presence in green risk management.

To accelerate its market entry, TMGX may also partner with managing general agents (MGAs)—independent firms that can underwrite policies on behalf of insurers. This approach allows Tokio Marine to expand quickly into underserved markets without the delays associated with building internal operational capabilities from scratch. “It’s a pretty quick win,” McLachlan noted, “it allows you instant access to a market.”

The launch of TMGX comes at a time when many climate-linked infrastructure projects risk stalling due to insufficient risk coverage. McLachlan warned that unless insurers step up with innovative solutions, the global transition to a low-carbon economy could be severely hampered. “Unless people start coming to the table with more creative insurance solutions… we’re going to see a lot of these projects stall,” he said.

Tokio Marine Group has made it clear that TMGX is not just a business venture but a core part of its corporate commitment to sustainability. The group stated that the GX initiative is aligned with global capital flows and regulatory pushes toward carbon neutrality. It plans to lead the market not only in underwriting but also in consulting and deploying advanced risk solutions that enable and support the transition to a greener economy.

By addressing the insurance gap in sectors critical to decarbonization and supporting the financial ecosystem needed to fund climate action, Tokio Marine is positioning TMGX as a pioneering force in the emerging green insurance market. As the pace of the global energy transition quickens, TMGX could become a key player in ensuring that the necessary infrastructure for a low-carbon future does not falter under the weight of unmitigated risk.
