Guinness Sustainable Energy
Overview
The Guinness Sustainable Energy strategy seeks capital growth and invests in companies engaged in the generation and storage of sustainable energy and the electrification and efficiency of energy demand.
Over the next 30 years, the world will transition to a sustainable energy system. The key factors driving the transition are:
- Population and GDP growth — putting a significant strain on today’s energy supply.
- Climate change — the world reducing carbon emissions via cleaner energy.
- Pollution — governments driving air pollution out of cities via cleaner energy.
- Energy security — sustainable energy tends to be distributed, and will lower reliance on energy imports.
- Economics — sustainable sources of energy will be cheaper than the incumbents.
The Guinness Sustainable Energy strategy is positioned to benefit from the many opportunities associated with this transition.

Rigorous independent analysis of the fundamental drivers of sustainable energy markets: energy commodity prices; sustainable energy technology research and development; installation and equipment prices; political and economic support for the sector; government and private sector demand; informs a top-down view that drives energy sub-sector allocation.
A disciplined stock screening process then identifies companies which look attractive on return on investment, valuation, earnings sentiment and price momentum. Each idea is then subjected to due diligence and detailed financial modelling before inclusion.

Commentary
August Commentary
This is a marketing communication. Please refer to the prospectus, supplement, KIDs and KIIDs for the Funds (available on this website), which contain detailed information on their characteristics and objectives and full information on the risks, before making any final investment decisions.
In July, the Guinness Sustainable Energy Fund (Class Y) returned -5.2% in USD, compared with 0.5% for the MSCI World Index. China Longyuan and Itron were the strongest performers, supported respectively by China’s mandatory renewable-consumption targets and Itron’s margin progression, while Infineon and NXP were among the weakest amid a broader sell-off in AI and semiconductor shares. The commentary focuses on electric vehicles: higher fuel prices following the Iran conflict improved near-term ownership economics relative to internal-combustion vehicles, helping sales rebound in the second quarter. Global EV sales grew nearly 20% to 21 million units in 2025, and the managers expect around 23 million units in 2026, with penetration reaching 27%. It also identifies cost, choice and charging as the three central barriers to longer-term adoption.

INSIGHTS IN FOCUS
How has the Iran conflict accelerated the energy transition?
The Iran war has removed around 12 million barrels of oil per day from global markets, triggering an energy shock with no clear resolution. Policymakers worldwide are responding with an accelerated push toward renewables, electrification and energy security. This structural shift looks set to reshape global energy markets for years to come. What does this mean for investors, and which parts of the energy transition stand to benefit most?
