A Global South-focused carbon crediting standard is partnering with forestry researchers to strengthen the environmental integrity of nature-based credits in carbon markets, the two sides announced on Wednesday.
Read MoreDisturbed peatlands release millennia-old carbon, study finds
Drainage and repeated fires released large stores of ancient carbon from tropical peatlands in Indonesia over less than two decades, with the estimated loss reaching 30-41 kg of carbon per square metre of affected peatland, researchers have found.
Read MoreFederal, policy roadmap shows US incentives needed to unlock 1 mln tonnes mCDR
Flagging waning federal investment in marine carbon removal (mCDR), a non-profit published a roadmap on Monday with policy and regulatory changes the US needs to implement to advance to the million-tonne scale of deployment.

A major carbon removal (CDR) registry will evolve to issue three different classes of credits, it said Tuesday, after announcing plans to certify units under the EU’s Carbon Removals and Carbon Farming (CRCF) scheme.
Read MoreBenin eyes carbon markets to help deliver new Paris climate plan
Benin has raised its climate ambition under a newly submitted Nationally Determined Contribution (NDC), pledging to cut greenhouse gas emissions by one-third over the next decade while positioning itself to tap international carbon markets under Article 6 of the Paris Agreement.
Read MoreNorth American organic fertiliser emissions below IPCC defaults, but swine manure emerges as hotspot -study
Nitrous oxide (N2O) emissions from North American agricultural soils amended with organic fertilisers are substantially lower on average than the default factors used in international greenhouse gas inventories, though certain manure types and management practices remain significant emissions hotspots, according to a new study.
Read MoreCarbon removals vulnerable to uncertain demand, concentration -report
Concentration among a handful of buyers, weakening prices, and policy uncertainty are threatening the scale-up of carbon removal (CDR) despite recent growth in the sector, according to a report released on Tuesday.
Read MoreF1 racing engineers play a role in soil carbon measurement breakthrough
