Biochar is produced through pyrolysis, a process where biomass combustion occurs in a low oxygen environment at very high temperatures. It results in a solid carbon-rich charcoal-like substance, which can be mixed into soil where it is theoretically stored.

By thinning cirrus clouds (wispy, elongated high-altitude clouds), some researchers have proposed that more heat could be allowed to escape into space, thereby cooling the climate.

Private tech money is rapidly accelerating solar geoengineering research. Funding has increased more than tenfold since 2020, largely from the US and UK. Who shapes decisions on these high-risk technologies – investors or democratic debate?

The Water Atlas presents the complexity and urgency of global water issues in a visually compelling, accessible format - from the unequal distribution of water and industrial pollution to climate-linked water insecurity and geopolitical tensions.

The global expansion of electromobility is intensifying competition for critical raw materials. A new analysis connects European supply chains to specific mining sites for the first time, identifying key environmental and social risks.

The burning of wood for energy is increasing worldwide, putting pressure on forests and ecosystems. This paper analyzes the development in Europe, North America, East Asia, Africa, and South America.

A circular economy can help mitigate the negative effects of our resource consumption and reduce the massive dependence on raw materials from other countries. The study sets out what needs to be considered in order to achieve a just transition towards a circular economy.

Concerns about Serbia’s Jadar project grow due to irregularities by authorities and Rio Tinto. Issues like sustainability failures, activist repression, unlawful assessments, corruption, and political influence, erode trust. This briefing covers the developments, concerns, and implications.

The briefing shows how the scenarios of the IPCC’s 6th Assessment Report (AR6) perpetuate existing inequalities into the future. It explores alternative perspectives that prioritize equitable futures, climate justice, and well-being for all in IPCC AR7.
