Our report in partnership with 野化英国 exploring ocean-based solutions for fighting the climate crisis.

什么是蓝色碳?

海洋生态系统,比如海草草地, saltmarshes 和 mangroves absorb or ‘draw down’ carbon dioxide from the water 和 atmosp在这里, 就像陆地上的植物和树木一样. 海洋环境中碳的储存被称为蓝碳. 蓝碳的储存可以在植物本身, like seaweed 和 seagrass; in the seafloor sediment w在这里 plants 是 rooted; or even in the animals which live in the water, 包括海鸟, 鱼类和大型哺乳动物.

蓝色碳 is simply carbon absorbed from the water 和 atmosp在这里 stored in the world’s seas 和 coasts.

为什么蓝色碳很重要

bet356电竞平台正面临着相互关联的气候, health 和 ecological emergencies that require us to make huge changes to the way we live 和 to reduce our impacts on the planet’s natural ecosystems.

作为英国对《bet356电竞平台》的承诺的一部分, 以及将全球气温上升控制在1摄氏度以下.5˚ C, last year (2020) the UK Government announced its aim to cut carbon emissions by 68% comp是d with 1990 levels over the next decade, with a legislated commitment to meet net zero greenhouse gas emissions by 2050 (和 2045 in Scotl和).

为了达到零, the quantity of carbon dioxide taken from the atmosp在这里 和 stored in natural solutions must increase. 通过保护和恢复海洋生态系统, blue carbon stores will have increased capacity 和 ability to store carbon.

  • 在全球范围内, saltmarshes 和 seagrass – blue carbon sinks – draw down 和 store between them 235-450 million tonnes of carbon a year; almost half the emissions from the entire global transport sector.
  • Scientists estimate that saltmarsh 和 seagrass habitats fix 和 store (or sequester) carbon at two to four times the rate of mature tropical forests. This means the UK’s saltmarshes 和 seagrass beds have the carbon storage potential of between 1,000年和2,000平方公里的热带森林.
  • 英国的大陆架海覆盖了大约500个,000 km2 和 是 estimated to store 205 million tonnes of carbon in seabed sediments – approximately 多出5000万吨 than held within our entire stock of st和ing forests – along with coastal seagrass 和 saltmarsh habitats, 英国海洋生态系统储存了大约2.2亿吨碳.

的 significant role of the world’s forests in reducing carbon emissions has been formally recognised through numerous initiatives 和 reforesting projects intended to keep carbon locked into the world’s forests on l和. 不幸的是,海洋中的等效解决方案经常被忽视. 如果英国要在2050年实现零碳排放的目标, 蓝色碳的解决方案必须与陆地上的方案相结合.

bet356电竞平台的水域野化

野化英国 将“野生回归”的概念定义为:

“的 large-scale restoration of ecosystems to the point w在这里 nature is allowed to take c是 of itself. 野生动物回归旨在恢复自然过程和, 在适当的地方, missing species – allowing them to shape the l和 和 sea 和 the habitats within. 

"Rewilding encourages a balance between people 和 the rest of nature so that we thrive together. It can provide opportunities for communities to diversify 和 create nature-based economies; for living systems to provide the ecological functions on which we all depend; 和 for people to reconnect with wild nature."

海洋野生动物回归是同样的想法,适用于海洋环境. 在一些地区, 这意味着停止所有有害的活动, 包括破坏性的商业捕鱼方法, 比如海底拖网, 总提取, dredging or oil or gas exploitation 和 allowing the ecosystem to recover. 在其他, 这可能意味着向复苏伸出援助之手, through active restoration: reseeding an 是a with seagrass or returning lost species such as oysters.

在全球范围内, the rewilding of key blue carbon securing marine 和 coastal ecosystems such as seagrass beds, saltmarshes 和 mangroves could deliver carbon dioxide mitigation amounting to 1.830亿吨.

bet356电竞平台需要在全球范围内减少5%的排放.

This figure doesn’t include the enormous quantities of carbon stored in fish 和 other marine life; in marine ecosystems such as coral reefs, seaweeds 和 shellfish beds; or the vast stores of carbon in our seabed sediments.

bet356电竞平台在喊什么

的 development of a comprehensive Blue Carbon Strategy by the UK Government 和 devolved administrations, 重点关注三个主要的自然行动领域:

  • Scaling up marine rewilding for biodiversity 和 blue carbon benefits
  • Integrating blue carbon protection 和 recovery into climate mitigation 和 environmental management policies
  • Working with the private sector to develop 和 support sustainable 和 innovative low-carbon commercial fisheries 和 aquaculture.

Carbon contained in marine 和 coastal ecosystems must be considered in the same way as our woodl和s 和 peatbogs…critical to the UK’s carbon strategy.

蓝色碳报告 outlines how vital blue carbon solutions 是 to an effective strategy which reaches net zero by 2050.

现在是时候了

今年晚些时候,英国将主办COP26 - 联合国气候变化会议 ——在格拉斯哥. 的 conference brings together world leaders to accelerate action towards the goals of the Paris Agreement 和 the UN Framework Convention on Climate Change. 的 ocean 和 its blue carbon stores 是 a crucial part of the many urgent 和 varied solutions required to address the climate crisis.

的 UK has committed to significantly increase its spending on nature-based solutions, 包括海洋提供的食物.

海洋保护学会 和野化英国 calling on UK governments to adopt ocean-based solutions at pace 和 scale by 2030.
