London Climate Action Week

Location: London, UK Date: June 25 — 27, 2024


London Climate Action Week is one of the world's largest independent climate change events. It brings together local and global experts from various sectors to harness the unique power of London for global climate action. The week is made up of hundreds of independent events where leaders, experts, and community representatives tackle climate issues, share their knowledge, and develop practical solutions both within their sectors and across the broader real economy.

This year’s themes will focus on four key areas: the road to climate ambition at COP30, financing the global climate transition, delivering a net zero and resilient UK, and mobilizing whole-of-society climate action. 

We will be contributing to the event with discussions on financing the global climate transition, speaking at the Climate Investment Summit, and hosting events on the topics of scaling transition finance, closing the UK green investment gap, and financing a nature-positive future.

Scaling Transition Finance

The financing needs of the climate transition are well understood, but we constantly hear from developers, financiers, and insurers about challenges and blockers in providing the appropriate level and type of finance and risk management. These challenges allow projects to be funded in the most efficient and rewarding way.

Join Oliver Wyman and Marsh to discuss the practical challenges of scaling transition finance. We will bring together representatives from the Insurance, Banking and Investment, and Energy and Power sectors to look at what needs to be done to smooth the way to more efficient and effective provision of finance for the energy transition.

Closing The UK Green Investment Gap

Levels of capital investment play a critical role in whether a company can meet its net-zero goals. Yet, 86% of UK companies disclosing through CDP dedicated less than a quarter of their capital expenditures to projects that are aligned with their transition plan or a sustainable finance taxonomy. This places the UK last among 16 countries that disclose CapEx alignment to CDP.

Join Oliver Wyman and CDP to explore actionable solutions to close the UK green investment gap. We will build on insights and case studies from our latest report, Get The Money Moving, based on an analysis of responses from more than 1,600 European companies disclosing through CDP.

A UK Perspective On Incentivising The Flow Of Sustainable Finance

While the City of London has retained its crown as the top global financial centre thanks to "London’s regulatory quality and openness to businesses through the newly introduced Financial Services and Markets Act and the Edinburgh Reforms", the question for this panel will be whether the UK is doing enough to incentivize the flow of sustainable finance and what changes could be on the horizon in an election year.
