London Action Climate Week

Location: Barclays HQ, Canary Wharf
Date: Thursday 26 June 2025
Time: 8:30am – 11:00 am

Hosted by Barclays and Environment Bank, join C-suite business leaders, including Aviva’s Thomas Viegas and Biodiversify’s Samuel Sinclair, for a panel discussion at LCAW.

Event overview

Nature is increasingly being recognised as a material issue for business.

From water availability and land degradation to evolving disclosure requirements like Taskforce on Nature-related Financial Disclosures (TNFD) and Corporate Sustainability Reporting Directive (CSRD), the ways in which companies depend on natural systems are becoming more visible. These are not just environmental issues; they have real implications for supply chains, risk exposure and corporate reporting.

Join Barclays, Aviva and Environment Bank for a high-level breakfast discussion during London Climate Action Week. This session will explore how companies are starting to treat nature as essential infrastructure, and how nature-related investments are beginning to play a role in supporting resilience, compliance and long-term value.

We will examine how businesses are responding to emerging frameworks such as TNFD and Science Based Targets Network (SBTN), and what practical steps leaders can take today to address nature-related risks and opportunities.
