Storebrand Asset Management has launched Storebrand US Plus, a climate-aware US equity strategy available to UK investors. Seeded with £150 million from Tatton Investment Management, the fund is domiciled in Luxembourg and available on over 20 UK platforms.
The strategy forms part of Storebrand’s flagship Plus fund range, which was launched in 2016 and manages approximately £10 billion in assets across developed and emerging markets[1]. The funds minimise exposure to fossil fuel and other environmentally harmful companies, while overweighting those that provide climate solutions.
Storebrand US Plus provides a benchmark-aware, climate-aligned core US equity allocation by targeting the return profile of the MSCI USA Index while systematically improving climate characteristics. The portfolio exhibits around 60% lower carbon intensity than the benchmark, double its FTSE Green Revenues exposure and has a materially higher allocation to companies with science-based targets[2]. The fund is also engineered to maintain tight control of active risk, operating at approximately 1% tracking error versus the benchmark.
Unlike rule-based climate indices, which can introduce unintended factor exposures and concentration risks, Storebrand US Plus uses a dynamic, model-driven approach. It also applies the latest scientific knowledge and data to build a portfolio aligned with the Paris Agreement and the broader climate transition — offering an alternative to traditional passive equity products.
Henrik Wold Nilsen, Senior Portfolio Manager and Lead for Storebrand’s Plus strategies, commented:
“Paris alignment is not simply about lowering carbon numbers in a portfolio but aligning investors’ capital with the real economic transition that must take place if its objectives are to be achieved. The US Plus strategy aims to preserve the behaviour of a core US equity allocation, while positioning the portfolio to provide more exposure to companies that will benefit, assuming the transition accelerates, and less to those that will struggle.”
Tom Hoyer Millar, Head of UK Distribution, Storebrand Asset Management, added:
"We are delighted to be partnering with Tatton, who have built one of the most established ethical MPS propositions in the UK wealth market. Their decision to seed US Plus is a strong endorsement of our investment approach. The fund combines Storebrand's thirty years of sustainable investment experience with a systematic, transition-aligned US equity allocation, and we're pleased to make it available to UK investors through a growing number of platforms."
Anthony Graham, CFA, Head of Fund Management and Chair of the Ethical Investment Committee, Tatton Investment Management, commented:
“Regionalising the equity building blocks within Tatton's Ethical portfolios meant finding a US strategy that screens out harmful exposures without introducing unintended factor tilts. Storebrand US Plus does precisely that: a disciplined, climate-aware core US equity allocation that is benchmark-conscious and cost-effective, sitting naturally within a portfolio built around principled exclusions rather than active ESG tilts.”
