Abstract
Reaching the carbon-neutrality targets of cities necessitates not only reducing emissions but also enhancing carbon sinks. This is enabled by urban green infrastructure (UGI), which is a cost-effective sink that provides numerous co-benefits beyond carbon sequestration. To fully harness this potential, it is essential to preserve existing carbon storage in urban planning, to create new multifunctional sinks, and to adopt low-emission practices in the construction and management of UGI.
Key findings
- Urban vegetation and soils provide a cost-efficient method of carbon sequestration and storage (CSS) that can be used more efficiently.
- In addition to CSS, UGI provides other co-benefits: it helps to alleviate urban flooding and heatwaves and enhances biodiversity and wellbeing.
- There are three key elements to harnessing UGI for adapting and mitigating climate change: preserving existing carbon stocks in UGI; creating new multifunctional carbon sinks; and adopting low-carbon practices and design options.
