Where Sustainability Professionals Should Focus in 2026

In 2026, sustainability professionals will be measured less by ambition and more by delivery. Leaders expect clear plans. Procurement needs supplier-ready requirements. Stakeholders want evidence that targets drive real operational change.

So the real question is not what is “new” in sustainability. It is where you should focus to create measurable impact.

Below are the most important focus areas for 2026 and practical actions you can apply across reporting, value chain emissions, net zero planning, and ESG data quality.

1) Supply chain sustainability becomes a daily requirement

In 2026, sustainability teams will spend more time with procurement, logistics, and suppliers. Why? Because customers and investors keep pushing for comparable value chain data, not just corporate headlines.

A big signal is how fast supplier disclosure is scaling. CDP says around 45,000 suppliers were requested to disclose through its Supply Chain program in 2025, with a focus on standardized, comparable supplier data including Scope 1, 2, and 3 emissions.

What this means for U.S. companies:
You will not “collect data once a year” and call it done. Instead, you will run supplier engagement like a business process.

Adaptation strategies for 2026

• Build a supplier sustainability tiering model (strategic vs. non strategic suppliers).

• Add ESG clauses to RFPs and renewals, with clear data deadlines.

• Create a supplier support kit (templates, FAQs, calculation rules, training).

• Track supplier progress quarterly, not annually.

• Align procurement KPIs with risk, resilience, and emissions reduction.

2) Scope 3 expectations rise as standards evolve

Scope 3 is still the hardest part of carbon accounting. However, 2026 will bring sharper expectations, partly because the standards ecosystem is evolving.

The GHG Protocol is running a coordinated update process across its corporate suite, including the Scope 3 Standard and Guidance. It also published a Scope 3 Standard Development Plan as part of that update effort.

At the same time, “regulation uncertainty” does not equal “no expectation.” For example, the U.S. SEC voted to end its defense of the 2024 climate disclosure rules, and litigation dynamics have continued to shift. Even when rules stall, investor and customer data requests do not.

Adaptation strategies for 2026

• Choose a primary Scope 3 calculation approach per category (spend-based, supplier-specific, activity-based).

• Document your assumptions like an auditor will read them.

• Prioritize 5 to 10 high-impact suppliers for primary data first.

• Put controls around emissions data the same way you treat financial data.

• Prepare for updates by building flexible calculation models, not rigid spreadsheets.

3) Net zero and Science Based Targets shift from pledge to proof

In 2026, the question will not be “Do you have a net zero target?” It will be “Can you show your pathway, your value chain plan, and your governance?”

The Science Based Targets initiative (SBTi) launched a draft Corporate Net-Zero Standard Version 2 for public consultation, signaling continued tightening around credible net zero planning and execution.

For U.S. professionals, this trend has a clear implication: net zero strategies must connect to real levers, such as procurement specs, logistics optimization, renewable energy decisions, and product design.

Adaptation strategies for 2026

• Translate targets into 12 to 24 month operational roadmaps per business unit.

• Define your abatement levers (energy, materials, logistics, suppliers, product use).

• Set clear rules for claims and marketing so you reduce greenwashing risk.

• Build internal accountability: who owns delivery, budget, and timeline?

4) Circular economy and ESG data expectations accelerate

Circular economy is moving beyond recycling messaging. In 2026, companies will need structured disclosure and stronger metrics on resource inflows, outflows, waste, and financial impacts.

In Europe, ESRS includes a dedicated standard on resource use and circular economy (ESRS E5), with disclosure requirements covering policies, actions, targets, resource inflows and outflows, and anticipated financial effects.

Just as important, ESG data is becoming more “digital-ready.” EFRAG highlights that the CSRD requires management reports in an electronic reporting format and requires markup of sustainability reporting using digital taxonomies (XBRL).

Even if your company is U.S.-based, you can feel this pressure through customers, capital markets, and global subsidiaries. Also, there has been debate in Europe about delaying or simplifying elements of green reporting rules, which adds complexity for global firms planning multi-year compliance programs.

Adaptation strategies for 2026

• Start a material flow map (top materials, packaging, and waste streams).

• Define circular KPIs you can defend (recycled content, reuse rates, waste intensity).

• Work with finance on how circular risks and opportunities affect costs and revenue.

• Prepare for “data structure” demands: definitions, lineage, and validation rules.

A practical 2026 playbook for U.S. companies

If you want to stay ahead of these trends, focus on execution. Here is a simple, trend-aligned plan:

1. Unify sustainability, finance, procurement, and legal in one governance rhythm.

2. Set a value chain data strategy (what you measure, how often, and why).

3. Build supplier engagement at scale with tiering, requirements, and support.

4. Strengthen your net zero plan with real levers and quarterly tracking.

5. Make your ESG data assurance-ready using controls, documentation, and consistency.

6. Upskill your team so sustainability, reporting, and supply chain leaders share one language.
