Mining companies believe extracting minerals from the ocean floor, like nickel and cobalt for electric vehicle batteries, could support the global energy transition and reduce global dependence on single nations with large reserves.

Environmental groups warn that deep-sea mining could cause damage to marine ecosystems and that stripping the seabed risks disturbing stores of carbon locked away for millennia, with unknown consequences. (Full story here).

Challenge: Ruminant animals like cows and sheep produce methane as a byproduct of their digestive systems, which is more potent than carbon dioxide in warming the planet. 

Potential: Research shows that low-emitting animals produce up to 20% less methane without affecting milk or meat output. 

Doubling-up: Combining the use of advanced genetic techniques to selectively breed low-methane-producing animals with other innovations like methane-blocking feed additives offers a strategy to reduce the global warming impact of livestock farming. 

Growth: In the last five years, from 2018 to 2022, VC investments in nature tech startups amounted to $7.5 billion. Annual investments increased from $1 billion in 2018 to $1.5 billion in 2022, with a peak in 2021 of $2.39 billion.

Geography: The US market attracted 78% of VC funding between 2018 and 2022, totalling $5.80 billion. 

Resilience: While the VC market declined sharply between 2021 and 2022 (-50% according to Crunchbase), nature tech funding was relatively less affected and fell by just 35%. 

Maturity: Early-stage investments in nature tech startups increased by +130% in value between 2020 and 2022, from $0.46 billion in 2020 to $0.77 billion in 2021 and $1.06 billion in 2022.

Bridging the gap: Connecting nature tech companies to real-world opportunities that enable the scaling of a solution, including finding customers willing to pay for these solutions at scale. This connectivity is still lacking and presents itself as companies struggling to scale as rapidly as they had hoped. 

Avoiding the hype train: In certain fields, the excitement and hype run ahead of market development. This can lead to credibility issues when project outcomes are later unable to support the original hype. It is important to find ways to ensure that nature tech solutions are scientifically sound before deployment.

Tech realism: Tech is often presented as a panacea, while there are often limitations to deploying tech in various landscapes and contexts. For example, drone seed start-ups have become more realistic about where they can be deployed.

Carbon offset developer South Pole has terminated its involvement in a project in Zimbabwe which has generated millions of carbon credits from efforts to prevent deforestation around Lake Kariba, the Swiss firm said on Friday. South Pole said it was not confident the Kariba REDD+ project - owned and developed by Carbon Green Investments (CGI) - met the standards it expected from its partners. (Full story here).
