Best way to survey B2B buyers about sustainable packaging preferences?

Surveys can work here but I'd pair them with a conjoint analysis to actually force trade-offs between cost and sustainability — otherwise buyers just say they care about both equally. Aim for 150-200 procurement decision-makers and use something like Qualtrics or SurveyMonkey Audience to recruit them. If budget is tight, even 8-10 in-depth interviews first will sharpen your survey questions significantly.
