To celebrate the Earth Day that was on April 22 this year, the market research company conducted a global survey of 28,000 consumers older 15 y.o. across 23 countries to find out their level of environmental consciousness and ethically driven buying behavior.

The study revealed that 76% of global respondents agreed that brands have to be environmentally responsible (vs. 6% who didn’t think so); 63% said they felt guilty doing something that hurt environment (vs. 14% who didn’t care); 63% said they bought products and services that appeal to their beliefs and values (vs. 11% who didn’t find any links between their purchases and beliefs).

Some more specific findings from the survey are, as follows:

1. Generally, women are more eco-conscious than men. 78% of women vs. 75% of men support the statement that businesses must be environmentally friendly. 29% of women vs. 26% of men strongly support the statement.

2. The age group of 30-39 y.o. is the eco-friendliest, followed by the group of 40-49 y.o. and over 60 y.o. who agree that businesses must be responsible.

3. Consumers from developing countries (India —93%, Indonesia—94% ) show more concern about the environment than consumers from the developed countries such as the U.S., Japan or Sweden.

4.  The age group of 50+ y.o. is the most numerous among those who feels guilty doing things that are not environmentally friendly (58%). Notably, 15-19-year-olds show the highest percentage of those who strongly agree the the statement.

5. 30-39-year-olds and 20-29-year-old dominate show the highest percentage (68% and 65%) among those who buy things according to their values and ideas. Again, developing countries lead the chart, while the developed Belgium and Sweden are in the bottom of the list.
