Clean Creatives claims the Edelman Trust Barometer is compromised by the firm's ties to climate deniers and autocratic states, alleging that the data overstates trust in governments that are Edelman clients and contradicts the firm's public climate commitments.

Carbon Market Watch defends its investigation into Colombian forestry projects, arguing that these projects produce 'hot air' credits that allow fossil fuel companies to avoid paying national carbon taxes. The organization refutes Verra's claims that its methodology was flawed, asserting that multiple assessment methods—including national reference levels and Ministry of Environment estimates—confirm the overestimation of emission reductions. It further contends that Verra's claims regarding community benefits lack transparency and that current auditing processes have failed to ensure environmental integrity.

The Rocky Mountain Institute (RMI) conducted a life cycle analysis (LCA) using the Argonne National Laboratories' GREET model to evaluate the environmental impacts of the Toyota Prius and the Hummer H3. RMI tested four scenarios, manipulating vehicle lifespan and assembly energy requirements to see if the conclusions of a CNW Research/Marketing report—which claimed the Prius was more harmful to the environment—could be replicated. RMI found that the Prius consistently has a lower environmental impact in terms of greenhouse gas emissions and energy consumption, regardless of whether assembly energy for the Prius was tripled or if the Hummer was assigned a longer lifespan (207,000 miles) compared to the Prius (109,000 miles). The report concludes that vehicle operation dominates emissions due to the Hummer's poor fuel economy, and that the CNW findings diverge significantly from scientifically reviewed work.
