The first 10 categories below primarily address positive environmental impacts, while the last four primarily address positive societal impacts.
It is a requirement that solutions do not have a negative impact on the environment and do no significant harm in any of the categories.
It is a requirement that each solution contributes to the achievement of at least one of the 17 UN Sustainable Development Goals.
Please note that solutions whose intention is to increase the efficiency of and reduce emissions from oil and gas recovery, even if they in themselves are green and have a sustainable business model, are not eligible for publication on The Explorer.
The above holds true for solutions designed to increase the efficiency of other traditional industries.
