[ESG Management Column] PLUG·QS·APPH...ESG Theme Stocks, 50% Rise Possible in Q4?

The US stock market in the third quarter of 2025 is entering a full-fledged transition period of the ESG investment paradigm, forming a new market. In particular, companies that prove tangible environmental, social, and governance (ESG) performance beyond mere concept investing are gaining attention, and the relative strength of ESG theme stocks, centered on the Nasdaq market, is prominent.

According to a first-half 2025 report by global asset manager BlackRock, the correlation between ESG assessment scores and stock returns of US listed companies was 0.78, demonstrating a close relationship. This trend is analyzed as a result of increased market reflection as the SEC's reinforced climate-related disclosure regulations and the EU's CBAM (Carbon Border Adjustment Mechanism), which officially took effect in 2025, accelerate ESG management by global companies.

Furthermore, in the Nasdaq market, where technology stocks have a high proportion, ESG factors are establishing themselves as key indicators for gauging a company's long-term growth potential. In particular, companies that systematically establish and implement carbon emission reduction targets are seen to receive an average of 12% higher market capitalization valuations within the same industry, showing a change in the valuation method.

In this changing ESG investment environment, Plug Power (PLUG) is emerging as a beneficiary of the full-scale hydrogen economy. In its recent second-quarter 2025 earnings report, revenue increased by 38% year-on-year to $289 million, and production capacity was expanded by 40% with the operation of a new plant in Georgia, USA. The proportion of hydrogen production based on renewable energy reached 48%, and ESG performance is also steadily improving, including a 23% reduction in carbon emissions compared to its own target.

QuantumScape (QS) is attracting attention by leading battery technology innovation. It has proven its technological competitiveness by completing the verification of solid-state battery (SSB) commercialization and achieving an energy density of 480Wh/kg. It is building a differentiated position in the sustainable mobility sector by being recognized for its 40% reduction in the life cycle carbon emissions of electric vehicles.

Meanwhile, AppHarvest (APPH) is showing its presence in the smart agriculture sector. It has not only increased harvest yields by 35% with the introduction of an AI-based crop management system, but has also recorded achievements such as a 95% reduction in water usage and an 80% reduction in pesticide usage compared to conventional agriculture, attracting attention as a model case of ESG management. In particular, achieving a 60% energy self-sufficiency rate through solar power generation suggests a new direction for the future of agriculture.

In the fourth quarter, changes in clean energy subsidy policies according to the results of the US midterm elections and the progress of discussions on the introduction of a global carbon emissions trading system to be discussed at COP30 are expected to be major variables. In addition, the industrial ripple effect from the improvement of water electrolysis technology efficiency (currently 75% → 85% target in 2026) needs to be watched.

As such, the trend of Nasdaq ESG theme stocks in 2025 is moving away from simple concept stocks and shifting to value assessments based on practical technology and management performance. What is important for investors is to consistently check the reliability and sustainability of the ESG metrics presented by these companies, and it is necessary to comprehensively evaluate technological development and regulatory response capabilities from a long-term perspective. In addition, it seems necessary to make investment decisions while continuously monitoring changes in the global regulatory environment and the pace of technological development.
