but duncan, who runs a cafe, has a health condition and reckons the scheme should go further. this is a polluted street, it is logged as a polluted street, and, yes, i have had a diagnosed sinus problem because i have been breathing dirty air. i think it is a step in the right direction. whether it will have a net effect on improving air quality, i would say no because not everybody is being charged and not everybody is being equally and fairly encouraged to reduce car usage, van usage, bus usage. more polluting vans and light goods vehicles will also have to pay £12.50 a day to enter the clean air zone, but not untiljuly. newcastle council says grants are available towards the cost of adapting vehicles. mark denten, bbc look north, newcastle. what do the wembley stadium arch, the shard and the big one roller coaster in blackpool all have in common? the steel tubes used in their construction were manufactured in corby in northamptonshire.
what do the wembley stadium arch, the shard and the big one now tata steel has announced a multi million pound investment to modernise the plant. they hope corby will become the country s first net zero steel factory. stuart ratcliffe has been given a tour. corby has a long and proud history of steel making, and that tradition continues today. here, steel coils are transformed into tubes for use in the construction industry. i think corby is very important to tata. we re one of the few tube makers left in the uk and the only tube maker that still makes hot finished tubes in the uk. but this process is power hungry. and now the double whammy of extreme pressures on the national grid, plus rising energy costs, have forced a rethink. just one of the furnaces here uses about ten megawatts of electricity per hour. that s the equivalent of the electricity for 11,000 homes, which is why from 11:00, this machinery is now switched off.
