Impact assessment of clean cookstove intervention in Gujarat, India: a potential case for corporate social responsibility (CSR) funding

Community kitchen tandoors (CKT)-a potential candidate for air pollution mitigation strategies?

Community kitchen tandoor (CKT) is a clay-based hollow cylindrical device commonly used in South Asian and Middle Eastern countries for baking flatbreads and cooking meat. These CKTs, generally fuelled by charcoal or wood, contribute significantly to the pollution loads in ambient air along with occupational exposure hazards. CKTs, being a part of the informal sector, lack emissions and safety guidelines. This study surveys 139 restaurants in CKT hotspots of New Delhi, India, to understand tandoor design and operational parameters and to assess PM_2.5 and CO exposure concentrations at representative field restaurants. PM_2.5 and CO exposure concentrations from traditional CKT was found to be several-folds higher than safe indoor air quality levels. Further, the traditional CKT was evaluated for different improved fuels (like briquettes and pellets) in the laboratory for PM_2.5 and CO microenvironment concentrations. It was found that the fuel improvements in traditional CKT could not improve microenvironment concentrations to the desired levels; hence, an automated pellet-fed forced-draft improved tandoor with an improved combustion chamber design is demonstrated. The results of the laboratory trial of improved tandoor were compared with traditional tandoor (using pellets) and have shown 84% and 94% reductions in PM_2.5 and CO concentrations, respectively, indicating significant benefits to the environment and health. We recommend implementing such improved CKT, on a large scale, combined with other identified control options, as a potential candidate under air pollution mitigation strategies in cities' action plans under National Clean Air Programme (NCAP).

The effect of corporate governance quality and its mechanisms on firm philanthropic donations: evidence from the UK

Purpose

This paper aims to investigate whether and how better corporate governance practices can lead to philanthropic behavior among companies in the UK. In particular, this study attempts to determine whether corporate governance quality in general, as well as its specific mechanisms, affects corporate giving.

Design/methodology/approach

The analysis is based on a sample of Financial Times Stock Exchange All-Share nonfinancial companies. Data on firm donations, including donations amount and donations intensity, were manually collected from companies’ annual reports for the period 2018–2020. This paper uses panel data models to examine the research hypotheses.

Findings

The results of this study indicate that both donations amount and donations intensity are positively associated with the practice of better corporate governance. Board independence is positively associated with donations amount, but not with the intensity of donations. Furthermore, board size, board gender diversity and the establishment of a corporate social responsibility (CSR) committee are likely to have a positive impact on the amount and the intensity of firms’ donations. However, neither the chief executive officer board membership nor the audit committee’s independence is related to the firm’s donations.

Practical implications

This study sheds light on specific governance factors that affect firm donations in the context of UK companies. This allows regulators and legislators to evaluate the donations activities in the country and issue more directives to reinforce corporate governance practices that support corporate donations. In addition, the findings of this study are considered crucial to investors who prefer investing in companies with significant CSR-related activities to improve the value relevance of their investments.

Originality/value

This study provides a shred of unique evidence on the impact of corporate governance practices on firms’ donations.

Do improved biomass cookstove interventions improve indoor air quality and blood pressure? A systematic review and meta-analysis

OBJECTIVES

This systematic review and meta-analysis evaluates the most recent evidence to examine whether use of improved biomass cookstoves in households in low-middle income countries results in reduction in mean concentrations of carbon monoxide (CO) and particulate matter of size 2.5 μm (PM_2.5) in the cooking area, as well as reduction in mean systolic (SBP) and diastolic blood pressure (DBP) of adults using the cookstoves when compared to adults who use traditional three stone fire or traditional biomass cookstoves.

METHODS

We searched databases of scientific and grey literature. We included studies if published between January 2012 and June 2021, reported impact of ICS interventions in non-pregnant adults in low/middle-income countries, and reported post-intervention results along with baseline of traditional cookstoves. Outcomes included 24- or 48-h averages of kitchen area PM_2.5, CO, mean SBP and DBP. Meta-analyses estimated weighted mean differences between baseline and post-intervention values for all outcome measures.

RESULTS

Eleven studies were included; ten contributed estimates for HAP and four for BP. Interventions lead to significant reductions in PM_2.5 (-0.73 mg/m³, 95% CI: -1.33, -0.13), CO (-8.37 ppm, 95%CI: -13.20, -3.54) and SBP (-2.82 mmHg, 95% CI: -5.53, -0.11); and a non-significant reduction in DBP (-0.80 mmHg, 95%CI: -2.33, 0.73), when compared to baseline of traditional cookstoves. Except for DBP, greatest reductions in all outcomes came from standard combustion ICS with a chimney, compared to ICS without a chimney and advanced combustion ICS.

CONCLUSION

Among the reviewed biomass stove types, ICS with a chimney feature resulted in greatest reductions in HAP and BP.
