The Oregon Department of Environmental Quality (DEQ) published proposed clean truck rules on Friday that would delay the implementation of low NOx regulations to model year (MY) 2026 engines, and create additional flexibilities within the Advanced Clean Trucks (ACT) regulations.

Market participants continued to cut their exposure to California Carbon Allowances (CCAs), while emitters went into a net short position in V25 RGGI allowances (RGAs) and once again built Low Carbon Fuel Standard (LFS) shorts, data published Friday by the US Commodity Futures Trading Commission (CFTC) showed.

The US Supreme Court may be poised to rule against the EPA in a pair of cases challenging the agency’s alleged penchant to transfer lawsuits to the friendly grounds of the DC Circuit court, although the outcome may hinge on the opinion of a single justice, an environmental law specialist said Thursday.

A newly released map of the nature tech sector has flagged gaps in biodiversity data management as well as unresolved challenges in making advanced technologies accessible to local communities and land stewards.

For decades, carbon markets and climate policies have relied on the Global Warming Potential (GWP100) metric to measure the impact of greenhouse gases (GHGs), but a growing number of experts say this method is flawed - particularly in its treatment of short-lived climate pollutants (SLCPs).

Engaging with the voluntary carbon market is risky for farmers because it can force them to relinquish rights to the CO2 credits generated on their land, by allowing outside organisations to claim them as their own, according to a UK-based consultancy.
