C2GDiscuss:探索树木在大规模清除二氧化碳中的作用

2022 年 1 月 24 日

政府间气候变化专门委员会 (IPCC) 认为,要将全球升温控制在 1.5° C 以下,在所有途径中都需要大规模清除二氧化碳 (CDR)。目前正在考虑一系列 CDR 方法,包括植树造林或重新造林等生物方法。在本期 "C2GDiscuss "播客中,执行主任亚诺什-帕斯托尔(Janos Pasztor)将带领政策、政府间、独立研究组织、非政府组织和学术界的专家们讨论这些 "基于自然的解决方案 "的作用。

According to the Intergovernmental Panel on Climate Change (IPCC), large-scale carbon dioxide removal (CDR) is required in all pathways to keep global warming under 1.5°C.  A range of approaches to CDR are under consideration, including technological or biological approaches, with the latter being increasingly referred to as "nature-based solutions."

Afforestation and reforestation, together with other nature-based approaches to CDR, have been gaining international attraction because of their huge potential to remove carbon from atmosphere but also due to the other prospective environmental and social benefits they could bring. However, there are concerns raised around "moral hazard," competition for resources, permanence of sequestration, and other potential risks of deployment of large-scale afforestation and reforestation, which pose governance challenges.

How do we address these challenges and make decisions that maximize synergies and co-benefits and minimize tradeoffs? What can we learn from previous large-scale afforestation and reforestation initiatives?

To explore these questions, C2G brought together a diverse group of policy, intergovernmental, independent research organization, NGO, and academic experts for a "C2GDiscuss" podcast on July 20, 2020.

Featuring:

  • Li Fang, chief representative, World Resources Institute Beijing Representative Office, China
  • Martin Frick, deputy to the special envoy, UN Food Systems Summit 2021
  • Thelma Krug, senior researcher (retired) at National Institute for Space Research, Brazil and vice-chair of the Intergovernmental Panel on Climate Change
  • Kelsey Perlman, (speaking on behalf of CAN International), forest and climate campaigner, Fern
  • Artur Runge-Metzger, director for climate strategy, governance, and emissions from non-trading sectors, DG CLIMA, European Commission
  • Janos Pasztor, executive director, C2G (Moderator)
