A Green Industrial Revolution

Debate between Wera Hobhouse and Bob Stewart

Wednesday 15th January 2020 Commons Chamber

[Bob Stewart]

I certainly do, and I want it to happen in my house as soon as possible.

We are decarbonising our economy faster, apparently, than any other G20 country, and we have reduced our emissions by 29% in the past decade, but here is the point: every breath we take is full of something called particulates, which, to be honest, I did not know much about until recently. These particulates—particularly something called particulate matter 2.5—are about 200 times smaller than a grain of sand, so they just float through the air and go into our lungs. They pass into our bloodstream and end up somewhere in our brain, or any of our other organs. I am told—of course, I am no expert, and I suspect that very few of us in the House are experts—that this causes illness and death. Having looked at the January 2019 report by the Department for Environment, Food and Rural Affairs, I understand that only 12% of particulate matter comes from vehicles.

[Wera Hobhouse (Bath) (LD)]

I am grateful to the hon. Gentleman for mentioning particulate matter, which is an issue of air pollution, but we should differentiate air pollution and climate change. They are two separate matters and we need to tackle them differently.

[Bob Stewart]

I accept that, and that I am no expert, so I accept the hon. Lady’s point of view, but particulate matter does have an impact on us all. Around 13% comes from industrial processes and 38% comes from wood burning and coal fires. That is quite a lot—more than comes from vehicles. I am looking up at the clock because I promised the Deputy Speaker that I would be finished in under 10 minutes—and I will.

I like the clean air strategy that was published in January last year: it is a good, bold new goal. We have to think carefully about using wood-burning stoves—I do not use the fireplace in my house anymore—and having open fires, and farms will have to change the way they do business. The move on the reduction of particulate matter has been welcomed by the World Health Organisation as an example for the rest of the world to follow.

As a good boy, I am now skipping through my pages, Mr Deputy Speaker, to make a final point. We produce about 1% to 2% of the world’s greenhouse gases. If we became carbon neutral right now, it might not make much difference, but that should not stop us doing it —we can become an example to the rest of the world—and the rest of the world is starting to follow and to deal with climate change. Bring it on: let us change the way we live so that the future is bright for those who follow us.
