Gordon Brown's budget fails to help Londoners who want to go green, according to Darren Johnson, a Green Party member of the London Assembly. Darren believes the Chancellor has failed on the three big policy areas where London needs Government action in order to achieve its climate change targets of reducing CO2 by 60% by 2025.

Darren Johnson commented: "The Chancellor's budget completely failed the green litmus test. His budget merely tinkers at the edges and has failed to provide real incentives for Londoners to reduce their carbon emissions."

The 50% increase in funding for household renewable energy grants falls short of the trebling of funding needed to keep up with demand: Grants for installing microgeneration (such as mini wind-turbines and solar panels) are so over-subscribed that this month they ran out within 75 minutes. Demand for renewables is at an unprecedented high in London. Grants should be made available for all householders wanting to install solar panels and wind turbines.

The small increase in road tax for gas guzzlers won't lead to a significant shift in the choice of greener vehicles: An increase over the next two years of the top rate to £400 is far short of the increase in VED to £1,800 for the most polluting vehicles, with a £300 gap between bands, as recommended by the Sustainable Development Commission. Surface transport accounts for 22% of London's CO2 emissions.

The Chancellor has failed to scrap any of the tax breaks for aviation: Aviation gets £9 billion a year in tax breaks every year, through exemptions from fuel duty and VAT. Rather than correcting this imbalance, last autumn's increase in air passenger duty merely restored it to its pre-2001 level. VAT and fuel duty should be levied on domestic flights, and air passenger duty should be increased to £100 on all flights until international agreements on taxing aircraft fuel can be reached. Aviation accounts for around 34% of London's CO2 emissions.
