                …rest. Between 50-60% of all efficiency investment spending is usually sourced from household savings or business equity, with debt finance making up the remainder. Financing solutions capable of supporting a large number of households are therefore particularly important to scale up investment in buildings and transport. Policy package Financing solutions Sustainability-linked loans: instruments where borrowers enjoy preferential terms depending on sustainability performance objectives. Such loans include predetermined key performance indicators (KPIs) linked to a set of calibrated (annual) sustainability performance targets that the borrower must meet. These targets can relate to reducing carbon emissions or improving energy efficiency…

                Critical Minerals

                Critical minerals are essential for a range of today’s energy technologies and for the broader economy. For example, lithium, nickel, cobalt, manganese and graphite are crucial to battery performance. Rare earth elements are essential indispensable to the permanent magnets used in wind turbines and electric vehicle motors. Electricity networks need a huge amount of aluminium and copper, the latter of which is the cornerstone of all electricity-related technologies. As demand for these materials grows strongly, their strategic importance has also increased – and policymakers have made ensuring secure and resilient mineral supply chains a major priority. Critical Minerals Security…
