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

Connect with people, visibly and loudly showcase initiatives that reduce greenhouse gases emissions, nurture youth leaders, or spread the message by raising awareness through campaigns. I am convinced that your contributions will ensure that climate change solutions safely power our - and especially your - future.

When you have a vision of where you need to go, it sounds utopian. But when you get to the tipping point, your understanding switches.

DEMAND, PURCHASE & USE LOW CARBON PRODUCTS AND SERVICES. MAKE LOW CARBON SEXY!

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.
