Mixed methods research: A comprehensive approach for study into the New Zealand voluntary carbon market

Abstract

Climate change and solutions to solving this wicked problem require a mixed methods research approach that draws on quantitative and qualitative inquiry together. The purpose of this article is to demonstrate the applicability (and effectiveness) of a mixed methods approach applied to research into the voluntary carbon market (VCM), a key path available for organisations electing to offset their carbon emissions, in New Zealand. The mixed methods approach included three unique data sets (quantitative documents, quantitative surveys, qualitative in-depth interviews), and was both explanatory (qualitative interviews built upon and contextualized the document analysis and survey results) and convergent (data sets were examined separately, then, as they represent different aspects of the same phenomenon, were combined for analysis). These complementary methods were used to gain a fuller picture of the evolution and institutional dynamics of the VCM field in order to produce a comprehensive case study.
