Drax's Sustainability Risks and the Erosion of Biomass as a Green Investment

In the evolving landscape of climate-conscious investing, the Drax Group has emerged as a cautionary tale for biomass energy—a sector once hailed as a bridge to decarbonization but now increasingly scrutinized for its environmental and governance risks. The UK-based power company, which transitioned from coal to biomass in the 2010s, has faced a perfect storm of regulatory probes, whistleblower allegations, and environmental backlash. These challenges not only undermine Drax's ESG credibility but also expose systemic flaws in the global biomass energy framework, urging investors to reevaluate their exposure to this contentious asset class.

The Drax Case: A Microcosm of Biomass's Risks

Drax's recent £25 million fine from Ofgem for misreporting biomass sourcing data—specifically, the use of wood from Canadian primary forests—has laid bare the sector's governance vulnerabilities. The regulator found “absence of adequate data governance and controls” in Drax's supply chain reporting, a revelation amplified by the whistleblower case of Rowaa Ahmar, its former Head of Public Affairs. Ahmar's tribunal testimony painted a damning picture of a corporate culture that prioritized spin over transparency, with executives allegedly instructing her to dismiss government inquiries and suppress concerns about sourcing practices.

While Drax settled the case and resubmitted its data, the fallout has been severe. Environmental groups argue that the fine is trivial compared to the £7 billion in subsidies Drax has received since 2012. Critics also highlight the carbon neutrality myth: burning wood pellets releases CO₂ immediately, while regrowth takes decades, creating a “carbon debt” that undermines net-zero goals. This has led to growing pressure on the UK government to revise its biomass subsidy policies, which currently treat wood pellets as a “zero carbon” alternative under the Renewables Obligation (RO) and Contracts for Difference (CfD) schemes.

Regulatory Gaps and ESG Rating Discrepancies

Drax's ESG ratings—such as an A- from CDP and a medium-risk score from Sustainalytics—suggest a veneer of sustainability. However, these scores fail to account for the company's systemic misreporting and the broader environmental impacts of biomass. For instance, the destruction of old-growth forests in British Columbia and the “environmental racism” of locating pellet mills in marginalized U.S. communities remain unaddressed in ESG frameworks.

The UK's regulatory framework itself is under scrutiny. Ofgem's supplemental statement in March 2025 acknowledged Drax's misreporting but stopped short of revoking its subsidies, citing no evidence of “unsustainable” sourcing. This leniency contrasts sharply with the EU's stricter biomass sustainability criteria, which now require proof of carbon neutrality and forest protection. Such regulatory inconsistencies create a patchwork of standards, allowing companies like Drax to exploit loopholes while eroding investor confidence.

A Global Shift Toward Cleaner Renewables

The Drax saga coincides with a broader global pivot toward solar and wind energy, which are outpacing biomass in both investment and public support. In 2025, global clean energy investment hit $3.3 trillion, with solar and wind accounting for $2.2 trillion—nearly double fossil fuel spending. Solar alone saw $450 billion in investments, driven by its scalability and cost competitiveness, particularly in emerging markets. Offshore wind, meanwhile, attracted $39 billion in the first half of 2025, outpacing 2024's total.

Biomass, by contrast, remains a niche player, with under $30 billion in 2025 investments. This disparity reflects both technological and regulatory headwinds. Unlike solar and wind, biomass relies on complex supply chains and land-use practices that are difficult to monitor. The IEA has warned that without stricter sustainability criteria, biomass could become a “carbon liability” rather than an asset.

Investment Implications and the Path Forward

For investors, the Drax case underscores the risks of overreliance on biomass. While the company's carbon capture plans and extended subsidy negotiations may offer short-term stability, the long-term outlook is clouded by regulatory uncertainty and environmental backlash. The UK government's proposed subsidy extension until 2031, albeit at half the current rate, hinges on Drax proving it can source biomass sustainably—a high bar given its recent missteps.

Investors should also consider the broader trend: solar and wind are not only cleaner but also more scalable and less prone to governance risks. The IEA projects that by 2030, solar and wind could meet 80% of global electricity demand, dwarfing biomass's potential. This shift is already reflected in capital flows, with emerging markets like Pakistan and India prioritizing solar over biomass for grid expansion.

Conclusion: Reevaluating Biomass in a Carbon-Constrained World

Drax's struggles are a microcosm of the biomass sector's challenges. While the technology has a role in niche applications—such as industrial heat and waste-to-energy—it cannot compete with the efficiency, transparency, and scalability of solar and wind. For investors, the message is clear: biomass is a high-risk, low-reward asset in a world increasingly defined by decarbonization and regulatory rigor.

As the UK and other nations refine their sustainability criteria, the Drax case serves as a wake-up call. The future of green energy lies not in burning wood but in harnessing the sun and wind—sectors where innovation, policy, and public sentiment are aligning to create a cleaner, more resilient energy system. Investors who pivot away from biomass and toward these technologies will be better positioned to navigate the carbon-constrained economy of the 2030s.
