Green, Blue, and Circular Economies: Why All Three Are Needed to Fight Climate Change

A recent opinion piece from BusinessToday Malaysia breaks down the three sustainability frameworks often lumped together: the Green Economy, the Blue Economy, and the Circular Economy. The author argues that confusing them leads to muddled policy and greenwashing. Green is about energy and carbon reduction. Blue focuses on oceans and water resources. Circular is about designing out waste entirely. Each has limits on its own, and real progress requires all three working together. The article uses concrete examples to show where these frameworks clash. Electric vehicles lower carbon emissions but rely on lithium mining that harms water ecosystems and rarely recovers rare earth metals. Paper straws feel eco-friendly but may come in plastic wrappers or from unsustainable forestry. The author warns that recycling alone cannot solve waste problems and that the circular economy must prioritize repair, reuse, and remanufacturing over recycling. The piece calls for treating these three approaches as precise engineering specifications rather than marketing slogans. A truly sustainable wind turbine, for instance, would be built from recyclable components, sited offshore without harming fish breeding grounds, and powered by decarbonized energy. The message is clear: half measures will not save the planet.
