So London has breached its pollution allotment for 2017 in the first week, and this has been a consistent thing for nearly a decade now. What are we going to do about this?
We've lost the rail freight depots. The Stratford one for instance is now a Westfield. This was a huge mistake as bringing in goods by electric rail would reduce our reliance on diesel to power so many lorries. Should we build new ones?
Private car use is high. Lower per-capita than other UK cities perhaps, but when one city has a tenth of a national population which has one registered motor per two-and-a-bit people you can pretty much guarantee the city will be choking. Should we limit private car use?
Electric cars don't pollute directly. Whether they pollute indirectly or not depends on where the electricity comes from: if your power comes from a solar roof or an offshore windfarm then your car is far less pollutive than if the power comes from a coal plant. Electric cars are expensive however. Should we find ways of making electric cars cheaper to consumers?
Sequestration is a process by which gaseous pollutants from industrial processes are condensed into liquid or solid form and stored or reused rather than being released into the atmosphere. Should we make sequestration of industrial sulphates and nitrates mandatory?
Should special powers be employed to increase rail links to districts with the highest rates of car use? Should zone 6 be extended into the Home Counties, so that an Oyster card will get you from Leatherhead into London? Cars burn fuel while waiting, should level crossings be banned in London and should existing ones be replaced with viaducts or cuttings?
These are all things we *can* do to reduce pollution in London. Now, what *should* we do?
