In the defence review, the Secretary of State was right to set out that grey zone warfare, terrorism, climate change and organised crime mean that the threats to our national security and international stability are becoming less conventional, less predictable and more continuous.

Our strategic threats are from China, which grows stronger each day from manufacturing trade, and Russia, which is threatened by China and relies on fossil fuel exports. Instead of focusing on cutting one in eight soldiers and stockpiling nuclear weapons, what discussions has the Secretary of State had across Government about using COP26 to put a carbon tax on trade, in order to check Chinese power and to help transition Russia from fossil fuels towards a wood economy for construction, to tackle climate change, so that holistically, we can protect the world without escalating the risk of war and destruction?

The hon. Gentleman actually raises an important point. At the beginning of the Command Paper is a chapter about the global trends and the direction. Climate change poses a security threat because it could deliver instability, poverty and problems in other parts of the world that would drive migrant flows and increase friction over precious resource. That is absolutely true.

The hon. Gentleman is also right to point out that one of the ways we are going to tackle our security threats is working together across the whole of Government to deal with them. The direction of travel on climate change will hopefully be set at COP26. Defence will play its part in both trying to solve its own emissions and making sure that it provides stability in some of the poorest countries, such as Sudan, where we recently had people, to make sure that the security threat sometimes delivered by climate change does not boil over and threaten regional stability.

I welcome the concentration on climate change in the integrated review. The Secretary of State will know very well that the worrying rate of retreating ice in the Arctic presents commercial opportunities as well as threats, yet at the same time, the Russians have increased their submarine and above-surface capabilities in the Arctic very considerably in recent years. What does the Secretary of State intend to do with regard to safeguarding our commercial vehicles, which may well be making use of the northern sea route, in years to come?
