My guiding principle is that prosperity can be shared. We can create wealth together. The global economy is not a zero-sum game.

In the quest for comparative advantage, investment will flow towards those countries that can offer more output for fewer emissions. Inaction will cost jobs. Action will support jobs.

If we change the way the electricity sector operates, we can bring down our levels of carbon pollution, and continue the crucial task of tackling climate change. Putting a price on carbon would do this.

There are some things that can't be measured.

Our nation is well equipped to make the transition. We have an abundance of natural resources like wind, natural gas, solar and geothermal.

The global economic outlook remains fragile and uncertain. Global economic imbalances persist and we must address them or risk future instability.

Afghanistan must never again be a safe haven for terrorism.
