ESG in the current geopolitical context

 

In 2026, many elements will influence sustainability goals for businesses, their capital providers, and their insurers. The US anti-ESG backlash and EU policy backsliding continue to cause confusion and challenge international progress on climate change and the broader green transition. However, despite the geopolitical headwinds facing ESG, the risks and costs from climate change continue to grow, as do the opportunities in the EU green economy.

For businesses based in Ireland, the EU, and the UK, multiple regulatory and customer pressures will continue to dictate ESG priorities in operations and supply chains. Demands from investors, lenders, and insurers for credible Climate Transition Plans persist amid the risks posed by climate-induced weather events.

Furthermore, Ireland’s EU presidency lead role from summer 2026 also dictates a policy focus on decarbonisation and sustainable finance. For the EU and the green economy, geopolitics is reshaping global competition on the net-zero transition. 

In terms of GHG reduction targets, Ireland aims for a 51% reduction by 2030 (vs. 2018) and net-zero by 2050 under the Climate Action and Low Carbon Development Act 2021. Ireland’s EU Effort Sharing Regulation target is at least 42% by 2030. However, the EPA forecasts that Ireland will achieve only a 23% reduction by 2030 based on current progress.

The EU target is at least a 55% net GHG reduction by 2030 (vs. 1990) and climate neutrality by 2050. In November 2025, a binding 2040 target of 90% net reduction was set, with up to 5% via international credits. The EU also adopted an indicative 2035 range of 66.25% - 72.5% as part of its updated Nationally Determined Contribution (NDC) submitted just before COP30, positioning this as a step between the 2030 and 2040 milestones.

The UK Government submitted its first NDC in December 2020, committing to at least a 68% reduction in economy-wide GHG emissions by 2030 (vs. 1990 levels). In January 2025, the revised NDC increased the target to at least 81% by 2035. The UK also aims for net-zero emissions by 2050.

Key ESG priorities for public and private organisations in Ireland and the EU in 2026

Climate transition planning remains a priority
Climate Transition Plans and validated, science-based GHG reduction targets (Scopes 1–3) continue to be a core expectation across the EU, UK and Ireland, driven by regulatory requirements and investor, lender and insurer scrutiny.

Supply chain regulation and traceability are accelerating
New EU laws, including CBAM, the Circular Economy Act and the EU Deforestation Regulation (EUDR), are increasing the focus on end-to-end supply chain traceability, compliance and data verification.

Biodiversity and nature are moving into the mainstream
Organisations are increasingly expected to broaden their sustainability strategies beyond climate to include biodiversity and nature-related considerations, supported by emerging frameworks such as TNFD and SBTi for Nature.

Reporting, assurance and credible claims are under greater scrutiny
Sustainability reporting frameworks continue to evolve, placing greater emphasis on ESG data quality, internal controls and robust substantiation of sustainability claims to manage greenwashing and regulatory risk across jurisdictions.

Digital and data capabilities are becoming essential enablers
Digital ESG solutions are playing a growing role in supporting data management, traceability and reporting, helping organisations respond more effectively to increasing information and compliance demands.

Sustainable finance is shaping investment decisions
Developments in sustainable finance are influencing how organisations approach capital investment, with a growing range of options available to support sustainability and decarbonisation objectives in 2026.

The articles below explore each of these themes in greater detail, outlining the key considerations and practical actions organisations can take in 2026 to support their sustainability objectives and remain aligned with evolving regulatory expectations. Further jurisdictional insight is also available in BDO Global’s Sustainability Reporting Jurisdictional Update (as of 31st December, 2025).

Key EU sustainability policies and timelines to plan for


Looking ahead, a number of EU sustainability policies and regulatory changes are expected to come into effect from 2026 onwards. Understanding the timing and direction of these developments will be important for organisations planning investment, reporting, compliance and operational responses.
