As one of the world’s largest independent climate events, London Climate Action Week (LCAW) forms an integral part of the global sustainability calendar, providing an invaluable platform for discussion whilst reinforcing the city’s role as a global hub for climate innovation and collaboration. This year’s LCAW, taking place from 20 to 28 June, was no different, bringing together leaders from finance, government and civil society to discuss practical responses to climate change, nature loss and the transition to a more resilient economy.
For investors, climate and nature-related issues are no longer peripheral sustainability concerns; they are increasingly influencing regulation, supply chains, energy systems, resource availability and company operating models. Understanding these shifts is essential to informing how we manage risk and position portfolios over the long term. Against that backdrop, LCAW offers an important opportunity for our teams to join discussions, learn more about emerging risks and opportunities from experts across industries and strengthen how we support clients and steward investments.
This year, colleagues from our Sustainable and Stewardship teams attended a number of events throughout the week, underlining how closely sustainability themes are linked to long-term investment perspectives and client interests.
On Tuesday 23 June, LGT co-hosted the Climate Week: Oceans x Fashion event at The Roof Gardens in Kensington. The event explored the links between ocean health and the fashion and materials economy, bringing together investors, scientists and sustainability leaders to discuss regenerative materials, marine biomaterials, blue bonds and areas of growing investor interest, including water-related themes. It also highlighted the role stewardship can play in encouraging companies to manage environmental impacts more effectively across their value chains.
On Wednesday 24 June, Siobhan Archer, Global Head of Stewardship, attended the Climate First Summit at Waddesdon Manor, attended by a small group of influential figures in the sustainable space. Discussions focused on the future of energy and artificial intelligence (AI), including grid infrastructure, energy storage, advancing nuclear energy and the growing relationship between power demand and AI-led technological change. These themes are of growing interest for investors assessing long-term structural trends, capital needs and the potential implications of the energy transition for long-term capital allocation.
Siobhan also represented LGT at the Afternoon Tea for Nature, hosted by the Circular Bioeconomy Alliance and Nature Alpha. The discussion centred on how to scale private capital for nature, with participants exploring how nature can be understood as critical infrastructure rather than a niche theme.
Together, these discussions highlighted how both transition and nature-related themes are becoming increasingly practical, measurable and relevant for investors. Siobhan commented:
With London temperatures reaching the high thirties, the focus on adaptation and resilience at this year’s Climate Week felt particularly poignant.
At our Oceans event, the panel struck a notably optimistic tone, especially around the opportunities in carbon sequestration and nature restoration. Discussions highlighted the work of Pristine Seas to establish marine protected areas and regrow coral reefs, as well as the development of new materials that are beginning to replace synthetic nylons and polyesters in fashion.
Nature remained a recurring focus throughout the week. Ruben Brooke, Portfolio Manager, attended the Nature Working Dialogues Reception, which brought together representatives from government, academia, business and civil society following the IPBES business and biodiversity assessment. Phoebe Stone, Chief Sustainability Officer, also moderated a panel at the Nature Hub at London Zoo on the design of robust nature-based projects, such as reforestation and habitat restoration, with a focus on delivering high-quality outcomes across finance, society and the environment. Key takeaways from the discussion highlighted that while scaling these solutions has become more challenging, requiring collaboration between buyers, investors and developers, the human dimension of these projects remains crucial, and solutions must place people and communities at their centre.
Investor stewardship remained another central theme. Abigail Lendvai, Senior Stewardship Analyst, and Heidi Droutsa, Stewardship Analyst, attended the Institutional Investors Group on Climate Change (IIGCC) Summit 2026, where discussions focused on the “age of implementation” within climate investing. Heidi joined workshops on physical risk data and the role of agentic AI in supporting investor climate goals, while Abigail also attended the PRI Investor Day and a Volans session on collective influence in climate policy engagement.
These conversations reflect LGT’s approach to stewardship, supporting long-term resilience and engaging collaboratively where wider market progress is needed. Abigail noted that one key message has cut through consistently:
Systemic action is no longer optional, and as investors, we need to use every lever at our disposal.
At the IIGCC Summit, the need for investors to move faster was clear, both in encouraging regulators to create policy frameworks aligned with climate goals, and in encouraging companies to support them. This applies to companies in the context of adaptation and resilience, but equally to us as investors in the ambition of our stewardship.
Ben Palmer, Team Head, Sustainable Portfolios, represented LGT at the Reset Connect Climate Conference, where he spoke on impact investing and the different approaches within ethical, responsible and sustainable investing. This reflects growing client interest in understanding how sustainability can be expressed through different portfolio approaches, depending on individual objectives, values and time horizons.
With over 300 exhibitors and 7,500 attendees, the event brought together exhibitors and stakeholders from across the whole climate ecosystem to share ideas and build networks, including nature and food systems, business and supply chains, wealth and investment, and tech and AI.
For LGT, London Climate Action Week was a valuable reminder that climate and nature are no longer separate from mainstream investment thinking, but core considerations that are increasingly shaping the economic backdrop in which companies operate, and with growing relevance for long-term investment outcomes. By bringing together voices from across the sustainability landscape, the week highlighted the breadth of disciplines, institutions and businesses helping to drive climate action, and connected global sustainability debates with the practical realities of investing and client advice. For our team, it remains an important opportunity to engage with leading perspectives, deepen our understanding of the themes shaping long-term risk and opportunity, and strengthen how we support clients in a fast-changing investment landscape.
