The UN Climate Talks, otherwise referred to as COP 20, begin next week in Lima, Peru at a time when climate change has rocketed back to the top of the global political agenda. The Lima talks are an opportunity for governments to harness momentum that has been growing around the world for months and begin taking internationally coordinated action to address the global climate change crisis. In Lima, governments can move forward on an international action plan to be finalized in Paris at the end of next year, which aims to accelerate the ongoing transition away from dirty fossil fuels to 100% renewable energy.

The foundation of any agreement in Paris will be built in Lima. That foundation includes getting nations to begin crafting Intended Nationally Determined Contributions (INDCs), where countries will offer their plans for how to slash global carbon emissions so that the world’s warming is contained to no more than 2degC. The deadline for the INDC offers is March 2015, making Lima an opportunity for governments to put the finishing touches on what these commitments should contain, how long they should last, and how they should be presented.

COP 20 is also an opportunity for governments to continue supporting the Green Climate Fund, which now has commitments for up to 9.6 billion in funding, but has an investment target of $100 billion by 2020. Politically, COP 20 comes at a pivotal time. In September, hundreds of thousands of individuals from New York to Mumbai took part in the People’s Climate March, where the demand for governments to act on climate was made at historic levels. Days later, the march was referenced by several leaders, including Barack Obama and Ban Ki-moon as a reason to act.
