A certifier expects to issue its first credits in the voluntary carbon market (VCM) this month, it revealed Tuesday as it rolled out a new methodology for forestry conservation that will quantify greenhouse gas removal.

One of the world's few urban forestry offset projects to date has been awarded high marks by a ratings agency this week, while two cookstove schemes have had their ratings reaffirmed.

Integrating carbon removals into the EU ETS will be essential to meet the current near-zero emissions goal by 2040, describing them as a "blind spot" in light of their current lack of attention ahead of crunch reforms due by the end of the year, an event heard on Tuesday.

Few in Somerset MP’s constituency share his enthusiasm but some do agree with need for ‘unpopular measures’
