2026 Sustainability & Net-Zero Forecast

The Regulatory Shift: From Pledges to Proof

Regulatory enforcement is no longer theoretical it’s active and impactful. In the UK, companies above certain thresholds must report under UK Sustainability Reporting Standards (UK-SRS), aligned with ISSB’s IFRS S1 and S2. These require audit-ready ESG data backed by third-party assurance.

The FCA’s Sustainability Disclosure Requirements (SDR) and anti-greenwashing rule demand that claims be substantiated, clear, and fair. Misleading environmental marketing now carries serious consequences up to 10% of global turnover.

In the EU, the CSRD now applies to firms with 1,000+ employees, with phased compliance through 2028. Larger companies must file in 2026 for 2025 data. Despite timeline delays, the burden of evidence has increased companies must substantiate their claims and disclosures with robust data.

The takeaway: sustainability reporting has moved from marketing to mandatory governance.

The Next Wave: Carbon Pricing and Border Adjustments

The EU’s Carbon Border Adjustment Mechanism (CBAM) enters its definitive phase in January 2026, applying carbon pricing to imports like steel, aluminium, cement, and fertilisers. UK importers with EU exposure must register as authorized declarants by March 31, 2026, and have verified emissions data ready. Carbon certificates must be purchased retrospectively starting in 2027.

The UK’s own CBAM will take effect from January 1, 2027, applying domestic-equivalent carbon prices to imported goods. Scope 2 (indirect) emissions will be phased in later, but businesses must now quantify embedded emissions and adapt procurement strategies.

Failing to prepare for CBAM means higher costs, supply chain delays, and compliance penalties.

Mandatory Transition Plans: From Vision to Accountability

The UK’s Transition Plan Taskforce (TPT) requires listed companies and financial institutions to produce detailed, credible transition plans. These must:

• Include near-term milestones (2026–2030)

• Address Scope 3 emissions with supplier strategies

• Outline financing methods (green bonds, SLLs, etc.)

• Integrate risk management through climate scenario planning

Generic “net-zero by 2050” statements won’t pass scrutiny. Transition plans are now binding, with regulators and investors demanding clear roadmaps and accountability mechanisms.

SME & Supply Chain Pressures: Transition Risks and Opportunities

Though SMEs may not face direct regulation, they’re under increasing pressure from their customers. Larger companies are being mandated to report Scope 3 emissions, pushing compliance demands down the supply chain.

Yet, most SMEs face challenges:

• 80% cite cost as the biggest barrier

• 70% feel overwhelmed by regulatory uncertainty

• Only 16% consider net zero a high priority

A two-tier system is emerging:

• Tier 1 suppliers to large enterprises are already under pressure

• Tier 2 regional suppliers may fall behind without support

SBS offers fixed-cost programs through our SBS Net-Zero Program,  Supply Chain Program and SBS Academy to help SMEs build capability affordably.

AI and Automation: Your Sustainability Reporting Advantage

Manual spreadsheets are no match for today’s ESG requirements. AI-driven platforms now automate data aggregation, validation, and compliance workflows across multiple business systems.

Key AI capabilities in 2026 include:

• Interfacing with finance, HR, and supply chain systems

• Alerting anomalies or missing data

• Generating first-draft reports and predictive benchmarks

• Managing assurance timelines and tasks

Companies using AI for ESG report 74% higher productivity and 22% better data quality. The ROI is clear investment in AI sustainability tools is essential for staying compliant and competitive.

Biodiversity & Nature Reporting: The Next Compliance Wave

2026 introduces structured biodiversity disclosure under GRI 101: Biodiversity and TNFD-aligned frameworks. Businesses must now assess their dependencies and impacts on nature particularly water, soil, and ecosystems.

What’s required?

• Map nature-related dependencies and impacts

• Assess risks across your operations and supply chain

• Determine materiality

• Begin structured reporting by sector (agriculture, food, energy, construction)

Unlike carbon data, biodiversity data is new terrain. Businesses need to start building processes now.

The Green Skills Gap: Strategic Risk or Advantage

Demand for sustainability expertise is soaring outpacing supply 2:1 in the UK. The country faces a shortfall of 200,000 green-skilled workers. Key shortages include:

• ESG strategy & governance

• GHG accounting

• Circular economy expertise

• Energy & waste management

Firms must upskill staff, redesign roles, or partner with consultancies. Our SBS Academy offers practical training and certifications to bridge the gap.

Early movers will reduce hiring costs and strengthen their ESG capability in-house.
