According to the world’s leading scientists, global emissions must peak by 2020 and then begin to decline rapidly if there is any hope of delivering the Paris Agreement and keeping global average temperature to rise to between 1.5 and 2 ̊C. Today, C40 announced that 27 of its cities have reached peak emissions . Peaking defines the point in time where emissions switch from increasing to decreasing, and represents a critical turning point in converting the Paris Agreement from aspiration into reality. The longer peaking is delayed, the later global emissions start to decline, and the more difficult it will be to limit global warming.
For more than a decade, C40 has been working with cities to develop and share policies and practices that help address climate change. We know that technological innovations cannot, in isolation, solve the challenges that cities face. Autonomous vehicle (AVs) technology is advancing at such a rate that it is now only a matter of time until AVs become the norm. Read more from C40 Executive Director Mark Watts.
C40 and CIFF recently launched a new online tool that will help cities understand the relationship between mitigation measures, which reduce greenhouse gas emissions, and adaptation measures, which reduce climate risk. Based on cities’ experiences and designed for cities, this is the first tool available that will help policy-makers systemically analyse potential interactions between mitigation and adaptation as they develop climate action plans.
The upfront cost of electric buses is higher than traditional diesel and CNG buses, but they present the unique advantage of having significantly lower operation and maintenance costs. In the current economic environment, many cities cannot afford a significant increase in the budget allocated to the renewal of their bus fleets and until now, only cities that have access to government incentives have deployed small numbers of electric buses by relying heavily on subsidies. This model however, is not scalable to 1000+ vehicles nor replicable to cities that don’t have access to similar support.
Urban citizens account for over half of the world's population. Analysis for the C40 Climate Leadership Group shows that by mid-century, climate change will likely pose an existential threat to some of the world’s greatest cities. The need to finance sustainable urban infrastructure in response to this threat is undeniably a defining global challenge of our time. Both the capital and innovative projects exist; now more than ever, all sectors need to play their part in bringing them together.
