Lewis Hamilton brushes off critics and steps up efforts to be more green

" Mercedes driver aims to be carbon neutral by end of year
" Hamilton can win sixth F1 world title at Mexican Grand Prix

Lewis Hamilton has robustly defended his environmental concerns, having received strident criticism for recent posts on Instagram. The world champion made a heartfelt statement after the Japanese Grand Prix in which he expressed his despair that more was not being done to address the climate crisis. He was disparaged by some for his stance, given the environmental footprint of Formula One that travels to 21 races across the globe.

Hamilton can win his sixth world championship at the Mexican Grand Prix on Sunday. He is 64 points ahead of his Mercedes teammate, Valtteri Bottas. If he is 78 in front of the Finn after the race the title will be his.
