Boris Johnson unveiled his green plans for London recently with a plan to pay Londoners to recycle.

The London Mayor pledged to boost household recycling by up to 200 per cent and reduce waste sent to landfill. He said he would work with the boroughs to reward householders for going green - rather than fining them.

He added: “It will actually improve the lives of thousands of Londoners.”

Local authorities currently pay £24 per tonne of waste sent to landfill, rising to £48 per tonne in the next three years, and are likely to pass on the cost to households through a bin tax.

But the Mayor has proposed a scheme which operates in more than 200 US cities and towns to keep down landfill. The firm would give every household a bin and every block of flats a box for all their recyclable waste - which would be weighed when collected.

The amount recycled would then be recorded and the household issued vouchers which can be spent at various outlets. In the US, more than 300 companies including Starbucks, Ikea and Timberland are part of the scheme.

He also plans to invest £6 million in making the capital’s open green spaces cleaner and safer and planting 10,000 street trees in areas which need them most. He said: “Areas that have pleasant, clean, open spaces are less likely to suffer from crime.”

His other green ideas include:

• Protecting the green belt and garden spaces.

• Cutting London’s carbon emissions by 60 per cent by 2025.

• Opposing Heathrow’s third runway.

• Encouraging us to install insulation in return for council tax rebates.

• Making London a genuinely cycle-friendly city, and hybrid buses

• An annual £20,000 prize for the best ideas for low carbon technology.
