The fight for Montreal’s environmental future has recently reached new heights, as various environmental groups in the city promote the installation of energy-efficient green and white roofs.

The London Development Agency (LDA) has congratulated a London company that has been recognised for its innovative and environmentally-friendly approach to construction.
The company was recognised for its potential contribution to the engineering and construction industries at the London Technology Fund (LTF) Competition awards ceremony held on Wednesday night at the Royal Bank of Scotland’s head office. Sarah Ebanja, Deputy Chief Executive at the LDA presented the Environment Award to Novacem, a start-up company developing carbon-negative cement.
Novacem, a spin-out from Imperial College London, has developed a groundbreaking type of cement, which has the potential to transform the cement industry from being a significant emitter of CO2 to being an absorber of CO2. Novacem estimates that for every tonne of ordinary Portland cement replaced by Novacem cement, around 0.75 tonne of CO2 could be captured and stored indefinitely in construction products.
Europe’s busiest diagonal crossing was unveiled today by London Mayor Boris Johnson following a £5million makeover which has seen Oxford Circus get the X factor.
For the first time ever shoppers will be able to cross the busy intersection diagonally in an ‘X’ as well as straight ahead – meaning the junction will be able to handle double the number of pedestrians and ease overcrowding.
Taking a lead from Tokyo’s famous Shibuya crossing, renowned for allowing large numbers to cross with ease, Oxford Circus, the gateway to London’s premier shopping destination, has had its barriers and street clutter ripped out and remodelled, giving the 200million shoppers and workers that visit annually around 70 per cent more freedom to move around.
