Protecting and restoring those habitats enhances carbon sequestration in the deep sea. Macro-algae forests are among the most productive ecosystems on Earth. Expanding seaweed farming enhances carbon sequestration and boosts the production of biomass that can be used for biofuel, bioplastic, livestock feed, and human consumption. Seaweed farming is one of the most sustainable types of aquaculture. They will also have additional benefits for reducing poverty, increasing equity, and protecting endangered animals and ecosystems. The report also found that these investments will save US$98 trillion and $140 trillion respectively, suggesting that practices and technologies implemented to reduce greenhouse gasses will more than pay for themselves. Their new research suggests that, between 20, an investment of US$15.6 trillion would be required to limit global warming to 2C, as set by the Intergovernmental Panel on Climate Change (IPCC) targets, and an investment of $23.6US trillion would be needed to limit warming to 1.5C. The recent Project Drawdown solutions arrive as part of an updated analysis. Following on from the success of Drawdown, Hawken published a second book: ‘ Regeneration: Ending the Climate Crisis in One Generation’. Project Drawdown emerged as a leading resource for information and insights about climate solutions after the publication of Hawken’s 2017 Bestselling book ‘Drawdown: The Most Comprehensive Plan Ever Proposed to Reverse Global Warming’. In addition to the database of solutions, Drawdown also runs Drawdown Labs – which works to advance the next level of business leadership on climate solutions, as well as Drawdown Lift – which aims to deepen collective understanding of the links between climate change solutions and poverty alleviation, especially in lower and middle-income countries in sub-Saharan Africa and South Asia. The research from Project Drawdown illustrates how the world can reach drawdown by mid-century via the use of currently existing and available climate solutions.
Every solution reduced greenhouse gases by avoiding emissions and/or by sequestering emissions that are already in the atmosphere, and all rely on extensive analysis of the scientific literature and sophisticated modelling. The breakthrough research required for the book has resulted in dozens of new scientific papers, and there are 20 more solutions coming that could create an even greater reduction in greenhouse gases.Project Drawdown’s research and analysis focus on solutions that are currently available, able to grow in scale, financially viable, have a net positive impact and are quantifiable. They are real, well-understood technologies and processes that can be scaled around the world. All solutions presented in Drawdown are not just hypothetical. Fortunately, major advancements have been made in the past decade to mitigate this problem. Moreover, these solutions would cost less than and produce more jobs that business as usual.What is drawdown? It is the reversal of greenhouse gases that have built up in our atmosphere primarily from the burning of fossil fuels – coal, oil, and natural gas. Combined it was shown that these 80 solutions could eliminate 1 trillion tonnes of CO 2 from the atmosphere by 2050, enough to prevent the dangerous climate tipping point of 2 degrees Celsius. Together this group developed a unique global systems model, evaluating 80 technologies and practices from the ground up – from innovative energy and agricultural methods to enhanced environmental conservation and restoration.The results shocked even the experts.
But a new book called Drawdown: The Most Comprehensive Plan Ever Proposed to Reverse Global Warming presents a way forward to create a future that is perhaps greater than anyone has imagined was possible.The project, led by activist and entrepreneur Paul Hawken, was started in 2013 and has since brought together over 65 researchers from across the globe with 128 experts in climate, sustainability, academia, and business. When you start to grasp the severity of the climate crisis, it’s easy sometimes to feel a little hopeless.
