About This Fund
1GT is a climate-focused private equity fund managed by Morgan Stanley Investment Management (MSIM), one of the world's leading alternative investment managers with over $240 billion in alternative assets under management. Launched in 2022 under MSIM's alternatives platform, 1GT takes its name from its defining mission: to collectively avoid or remove one gigaton of carbon dioxide-equivalent (CO2e) emissions from the Earth's atmosphere from the date of investment through 2050. The fund held its first close in May 2023 at $500 million and reached a final close in September 2024 at $750 million in equity capital commitments, drawing institutional support from leading investors in Europe, Japan and North America.
1GT targets growth-oriented investments in private companies across North America and Europe that operate in five climate-critical sectors: clean mobility, power, sustainable food and agriculture, and the circular economy. The fund is structured as a growth equity vehicle, partnering with expansion-stage companies at the point where meaningful scale can deliver both outsized emissions impact and superior financial returns. A unique feature of 1GT's incentive structure is that half of the investment team's carried interest is directly tied to achieving the one-gigaton carbon-reduction target by 2050, aligning the team's compensation with climate outcomes rather than financial performance alone. MSIM leverages its global platform and corporate relationships to support portfolio companies in pursuing earnings growth, multiple expansion, and enhanced exit potential.
Since launch, 1GT has deployed capital across a growing portfolio of climate-positive businesses. Notable investments include Instagrid, a German manufacturer of high-performance portable battery systems enabling the electrification of construction worksites; Huel, the UK-based sustainable nutrition brand producing complete foods with a significantly lower carbon footprint than conventional diets; and Everstream Analytics, a supply chain intelligence platform that helps multinational corporations reduce emissions through optimized routing and responsible sourcing. These investments demonstrate 1GT's core thesis: that disciplined financial underwriting and measurable climate impact are mutually reinforcing objectives that, when properly structured, produce superior risk-adjusted returns.
