Nonlinear counterproductive effects of VOC and NOx reductions in ozone control3 questions
  1. Propagation of emission-inventory uncertainty into response-surface-model predictions of ozone response to NOx and VOC emission controls in China

  2. Speciated anthropogenic VOC emissions and the surface-ozone response to NOx emission controls in Beijing and northern China

  3. Integrated NOx–VOC–CO emission-control design to reverse China's surface-ozone increase

Cross-regional failures of low-cost air sensor calibration models3 questions
  1. Validity limits and maintenance of global multi-unit calibration laws for low-cost particulate matter sensor networks across locations, environments, and operational time

  2. Region-transferable calibration of low-cost optical PM2.5 sensors for epidemiological exposure assessment

  3. Calibration of low-cost air-quality sensor systems robust to relocation: can designed, balanced laboratory data replace field collocation?

Pollution transfer explanations in the environmental Kuznets curve3 questions
  1. Robustness of the consumption-based global CO2 Environmental Kuznets Curve and the design of hybrid producer–consumer carbon accounting

  2. Identifying the mechanisms behind spatial spillovers in the trade-adjusted environmental Kuznets curve for CO2 emissions

  3. Does offshoring production to low-wage countries offshore their pollution? Net environmental impact, governance mode, and firm environmental standards

How lifecycle emission reductions from waste incineration depend on the electricity generation mix2 questions
  1. Which electricity does energy-from-waste displace? The open displacement-assumption problem in life-cycle carbon appraisal of UK waste incineration versus landfill

  2. Robustness of the life-cycle environmental ranking of municipal solid waste incineration power generation versus landfill and coal power in China: biogenic-carbon accounting, inventory localization, and technology/composition generalization

Decoupling between corporate environmental information disclosure and actual emission reductions3 questions
  1. Do corporate climate policy mixes cause absolute emission reductions? Causal identification, stringency measurement, scope 3 coverage, generalization, and reporting reliability

  2. Do LLM-measured corporate climate narratives track realized emissions performance over time? Longitudinal extension of the disclosure-maturity framework of Hassani, Bahini and Mushtaq (2025)

  3. Do China's state-owned polluters respond to environmental information disclosure, and which institutional mechanisms break political protection?

Additionality and leakage issues of ecological compensation policies3 questions
  1. Conditions under which asset-building hybrid PES–ICDP arrangements in legally restricted areas can deliver lasting poverty reduction, maintain conditionality, and permit termination of payments with full enforcement of environmental law

  2. Costly, imperfect, and spatially heterogeneous monitoring and enforcement in spatial avoided-deforestation policy design

  3. Total deforestation leakage from protected areas in the Brazilian Amazon: quantifying local spillover plus distant displacement under a robust counterfactual baseline

Estimation discrepancies of the actual substitution ratio of recycled plastics for virgin materials3 questions
  1. Demand-side limits to plastics circularity: the property-explicit absorption capacity of product markets for secondary plastics

  2. Empirical constraints on the virgin-substitution potential of mechanically recycled PET, PE, and PP in Europe: quality-loss substitutability (cascading pathways and maximum recycled content) and market absorption of large recycled supply

  3. A settled estimation method for technical substitutability coefficients of secondary materials in waste-management life cycle assessment: multi-property functionality and multi-loop recycling mixtures

Systematic underestimation in greenhouse gas emission inventories of wastewater treatment plants1 questions
  1. Quantifying and attributing dissolved nitrous oxide discharged in sewage treatment plant effluent, and incorporating it into nitrous oxide emission inventories

Sensitivity of PM2.5 source apportionment results to receptor model choice1 questions
  1. Principled ensemble combination of receptor-model PM2.5 source apportionments: weighting, unresolved sources, and cross-model uncertainty propagation
