We, the older generations, simply cannot leave a world for you, the younger generations, in which climate change impacts become ever more threatening to your survival. Still more public attention and action are needed. Solutions like renewable energy or energy efficiency need to fully power our collective future!

The record-breaking extreme weather events causing chaos across the globe should be a wake-up call. The transition to a low-carbon economy will be much more painful if we wait until there is a climate crisis before recognising that more than half of the world's fossil fuel reserves will have to remain in the ground.

Carbon neutrality is going to be so standardized that you will look at anything that is not carbon neutral and go, "where the hell did that monster come from?" It's exciting.

No architect should design buildings that import a huge amount of energy.

We are just about to cross the 400 parts per million threshold.

We have already used more than half of that budget. This means that three quarters of the fossil fuel reserves need to stay in the ground, and the fossil fuels we do use must be utilized sparingly and responsibly.

Each building should produce as least as much energy as it's going to need, and have more to put on the grid. They should be using all of the natural light and natural heat.
