Ocean-based negative-emissions technologies present many challenges

Envirotec Magazine

The use of so-called “negative emissions technologies” to enhance carbon sequestration and storage in the ocean is increasingly being discussed. This process, also known as alkalinization, harnesses chemical processes to alter the geochemistry of seawater and thereby increase the uptake of carbon dioxide from the atmosphere.

Heard of “Net-Zero Oil” or “Carbon Negative” Bioenergy? In 2023 You Will

DeSmogBlog

Salmon might seem like a good alternative to meat, in a world that needs to shift away from carbon-intensive cattle — at least the fish farming industry would have you see it that way. Carbon Capture and Storage. Below, a handful of DeSmog writers dive into the issues they’ll be watching in 2023. Aquaculture. Next year you will.

Geophysical experts call for ethical framework in geoengineering deployment

Envirotec Magazine

Climate change requires immediate action, and our most urgent, non-negotiable priority must be to tackle the root cause, carbon emissions,” said AGU President Lisa J. Climate intervention research should not be presented as an alternative to emissions reductions. They should clearly report any negative results.

Over 650 scientists urge world leaders to stop burning forests for energy on eve of UN nature summit

Envirotec Magazine

The Drax power plant in North Yorkshire is the UK’s biggest single-point source of carbon dioxide emissions, and is fed by a constant supply of wood pellets shipped to the UK on enormous vessels, mostly form North America. Estonia, and Canada – and the UK–the world’s top importer of wood pellets for biomass energy.
