This is because art is often very labor intensive and not particularly material heavy.
If you buy something that takes a long time to make - instead of cheap mass-produced goods - your money goes to the working hours and not so much to the materials. After all, working hours do not pollute - so do materials.
In short: Buy quality rather than quantity.
Glass art has to be burned several times in the kiln and it costs electricity. Here you must use green power. In 2019, the share of green power in Denmark was 72%, and the share is increasing.
All electricity suppliers receive electricity from exactly the same sources, some of which are extracted from, for example, wind power and solar energy, and others from, for example, nuclear power, coal and oil. When buying electricity from a green electricity supplier, the electricity is thus still 72% green. What the green electricity supplier ensures is:
- That electricity from eg wind power can be sold - ie there are buyers for the green power.
- That a share of the cost of the electricity is used to expand the green energy sources.
