The document discusses the challenges and opportunities for reaching a new global climate change agreement in Paris in 2015. It outlines that while staying below a 2 degree Celsius temperature increase is still possible, current trajectories have the world on track for a 4 degree increase. It argues that addressing climate change can help solve air quality problems in emerging economies and that renewable energy should be used to provide energy access in order to avoid these issues. Finally, it provides an overview of the key elements and building blocks needed for the new Paris agreement, including transparency, green financing, technology sharing, adaptation support, and commitments from all countries in a legally binding agreement.
