Thus, should such recommendations meet the approval of EU member states, a set of green bond standards could emerge within the next couple of years, which bodes well for stimulating further financing for green projects into the next decade. But the importance of the green bonds market transcends both the raw numbers and its role as a "marketing phenomenon" to signal the commitment of a bank or government to environmental protection and climate action. Recent analysis by NatWest Markets suggests that while unlocking more finance for clean energy, infrastructure and other green projects is obviously crucial, the expansion of green bonds also can foster more sustainable thinking throughout financial circles more generally, helping to promote climate change beyond a mere niche concern. NatWest calls this the "halo effects" of a green bond, arguing that an issuance can put pressure on a bank's, government's or company's wider bond offering — including non-green bonds.
