歐盟氣候計劃(fit
for
55)旨在到2030年將溫室氣體排放量減少55%(1990年)，鑒於對未來人口增長對應的作物、肉類等民生需求，生物能源、降低民生物資之碳足跡和增加耕地面積成為重要對策。據歐盟預測，2050年生物能源使用量將比2015年多一倍，故現以生物能源視為碳中和為主軸發展，且增以外包方式維持糧食生產，然而耕地面積、生物能源用地具邏輯拮抗，有關生物能源規則應納入「碳機會成本」(土地、生物質)之核算，則可能將繼續損害歐洲和全球的碳儲存和生物多樣性。
Researchers
at Newcastle University discovered
that volcanic rock powder, when used
as fertilizer, could increase crop
yields by up to 22% while capturing
carbon. Manufacturer UNDO is
distributing the powder to farmers
for free in exchange for carbon
credits. This innovative approach
combines carbon capture with
fertilization, offering potential
benefits for both agriculture and
the environment. With accessible
volcanic rock in regions like North
East England, this method holds
promise for scalable implementation
in farming practices.
A
Nature study supports the scientific
credibility of forest-based climate
solutions, highlighting four
pathways as robust. While some
solutions like coral reef
preservation lack certainty, others
such as enhanced rock weathering and
biochar require further research
despite significant investment. Most
carbon market investments focus on
credible forest-based activities,
indicating the need for diverse
climate solutions. Nature-based
approaches are crucial alongside
technology-based ones to meet
climate targets by 2030.
