Sustainable finance is a reality that combines profitability with environmental impact. For startups, this trend creates new opportunities to access capital tied to ESG criteria and success metrics that go beyond purely financial ones.
Definition and rationale of sustainable finance
Integrating sustainable development principles into financial decision-making is the foundation of sustainable finance. It involves directing investments and governance toward projects that generate environmental and social benefits, not just immediate returns.
Practical evidence: cases and data
Concrete data show how structured instruments can accelerate green capital. An emblematic example is Dolomiti Energia, which issued a €300 million green bond retail to finance wind generation, solar photovoltaic generation, and electricity distribution. Results showed strong demand from retail investors: €200 million sold on the first day and a further €100 million opened subsequently, in about 30 minutes.
'The first day we issued 200 million, we closed them in a few seconds,' recalled Donnini. 'The second day we reopened for another 100 million, and in about 30 minutes they were sold.'
Investors seek instruments with clear metrics and transparent governance, keys to access capital and valuation. Companies attentive to ESG criteria tend to be more solid over time, because they integrate environmental and social criteria from the outset. For startups, defining an ESG track record, effective governance, and a pipeline of metrics can facilitate access to venture capital and impact-oriented debt instruments.
Implications for startups and investors
Financing opportunities tied to ESG and sustainability require clear metrics and transparent governance. This makes clear the importance of defining environmental and social KPIs, reporting reliably, and building a credible impact narrative to attract investors and partners.
Looking at green capital as a driver of innovation
Sustainable finance is a lever to innovate and scale projects with real impact. For startups aiming to grow responsibly, aligning strategy, ESG metrics and finance can translate into access to stronger partners and markets.
