Westminster Hall is an alternative Chamber for MPs to hold debates, named after the adjoining Westminster Hall.

Each debate is chaired by an MP from the Panel of Chairs, rather than the Speaker or Deputy Speaker. A Government Minister will give the final speech, and no votes may be called on the debate topic.

Following the heatwaves and wildfires across Europe this summer and the destruction caused by the glacier collapse and catastrophic flooding in Nepal and Tibet, the message is becoming impossible to ignore: the consequences of climate change and environmental degradation are real, not some distant future threat.

As the national security risk assessment says, climate change, biodiversity loss and ecosystem disruption pose risks not just for the environment but for our economy, security and way of life. Climate and nature shocks are arriving faster, harder and more systematically than many of our economic systems were designed to handle.

We see that in four main ways: physical risks, including floods, wildfires, droughts and storms; transition risks as economies move away from high-carbon industries; nature-related risks affecting food production and natural resources; and systemic risks, where shocks spread rapidly across sectors and markets.

For many years, conversations about green finance primarily focused on corporate social responsibility. Today, they are equally about resilience and risk management. The UK is well placed to lead on that, but I fear that we are not doing as much as we could be.

I am vice-chair of the all-party parliamentary group on Tibet. What is happening in the Himalayas and the Tibetan plateau is one of the clearest examples of climate risk unfolding today. The glaciers of the third pole function as Asia’s water tower, feeding major river systems that support nearly 2 billion people. When rising temperatures accelerate glacial melt, the consequences extend far beyond the mountains. This is not simply an environmental catastrophe; it is about infrastructure resilience, water and energy security, as well as economic stability across the entire region. It is entirely the kind of systemic risk that modern resilience finance should help countries to anticipate and manage.

I conclude by asking the Minister this: who will be attending COP17, and will we make sure we show leadership on global resilience there?
