Climate change imposes an existential threat on the globe and has already had sizeable
economic costs to countries. Environmental aid flows aim to alleviate the rising concerns of climate change in the developing world. Even though the existing literature
has examined the effectiveness of green aid flows for reducing carbon dioxide emissions in the recipient countries, no existing study has examined the effectiveness of
different classifications of green aid. Examining the green aid flows to 97 developing
countries between 2002 and 2018, we find that all types of green aid significantly
reduce carbon dioxide emissions; however, the aid flows targeting the environmental
objectives are more effective in reducing carbon dioxide emissions compared to the
aid flows that do not target environmental objectives or are not screened. The findings
highlight that more aid should be screened and targeted for environmental objectives
to increase the effectiveness of green aid flows in developing countries.
