These economic priorities will run in concert with, not be road-blocked by, my desire to make London a greener place to live and work. That must be the balanced approach that any Mayor makes to the capital's multi-faceted challenges, and I look forward to showing why I am uniquely suited to rise to that task.
This latest episode in the air pollution debate signifies how politically toxic accusations against the Mayor's air pollution policies have become. Clearly, if you dare to question the Mayor's commitment to the issue you might find yourself on the receiving end of an angry letter and veiled threats...
I believe that if politics is about anything, it should be about improving people's lives and bequeathing something better to our children than we ourselves inherited. If internationalism is about anything, it is about doing that for people around the world regardless of where they live. That's what environmentalism and sustainability mean to me.
When the Government published its aviation policy framework in draft form, it asked the right questions about noise, air quality and climate change, but the final version fails to deliver on these. It is disappointing that so few of the recommendations we and others made have been taken up by the Government.
When London won the Olympic bid, it was claimed that these would be the 'greenest Olympics ever'. While there have been some important green strides, some of which undoubtedly can be used to inform future major sporting events, it's been disappointing that so many of the initial green pledges have since been dropped.
