Happening This Week

NYC is planning $27 billion in green bond-funded infrastructure resiliency improvements. Green bond programs, only conceptualized in 2008, have already become an essential funding tool for climate change initiatives. Cities like Oakland, Los Angeles, and DC pioneered the system using green bonds to fund major infrastructure projects that cut carbon or build resilience, but that is small potatoes considering that Green bond issuance is expected to quadruple between 2013 and 2014.

The growing acceptance of this new financing strategy comes at an opportune time as a new EEA survey shows European countries struggling to move forward with climate change adaptation plans already included in legislation, citing "time, money, or technology" as significant obstacles.

In an effort to curb similar impediments in the US, the White House announced the new Climate Action Champions Competition this week, which pits successfully greening communities in a battle for federal assistance. Winners will receive both technical and financial support for work on green projects, with a focus on those that simultaneously shrink their carbon footprint and bolster resilience to natural disasters. A second competition is planned for communities with limited resources that have demonstrated commitment and motivation to climate change mitigation and adaptation.

Green bonds and the White House competition are two great illustrations of the need for both public and private efforts to support climate adaptation. Our latest blog post, published on the Huffington Post, discusses the crucial role of business in community resilience.​
