Water Criteria on Nature-based and Hybrid Water Infrastructure: Consultation and Webinars

On behalf of the Water Consortium, the Climate Bonds Initiative has released Water Criteria Phase 2: Nature-based and hybrid water infrastructure for public consultation.

The Water Criteria are a key component of the science-based Climate Bonds Standard and Certification Scheme - a screening tool for investors, development banks and governments, which allows them to easily prioritize climate and green bonds with confidence that the funds are being used to deliver climate change solutions. A 60-day public consultation period for the Phase 2 Criteria opens on 16 October.

Two webinars about the new Water Criteria have been announced: 25 October and 20 November. Details are below.

Workshop on Scaling Up Nature-Based Flood Risk Reduction

Nature-based solutions (NBS) are increasingly being used for flood risk reduction and climate change adaptation, especially in developing countries where they are most needed. Examples are the use of mangroves for wave reduction and erosion control and the use of urban green spaces for retention of storm waters. If properly implemented, NBS can aid in reducing flood risk while also providing additional benefits for people, the economy, and nature conservation. However, effective implementation is challenging, as it requires integration of different disciplines and the active involvement of government and communities. In addition, proper metrics for success and adequate monitoring methods are yet to be defined. Since NBS are currently not tested to the same standards as traditional grey infrastructure, trade-offs in terms of engineering and economics are still hard to make.

The World Bank, Deltares, UNDP, and Ecoshape will be hosting a two-day workshop on scaling up NBS flood risk reduction. The meeting will focus on producing guidelines for the effective implementation of green and hybrid solutions to reduce flood risk in urban, riverine, and coastal settings.
