<p>A growing number of countries are committing to ambitious target of net-zero emissions by 2050, as a show of commitment to implement the Paris Agreement. Sectoral net zero roadmaps are also beginning to emerge. For example, the International Energy Agency (IEA) is due to publish, in May this year, it&rsquo;s first comprehensive roadmap for the entire global energy sector to reach net-zero emissions by 2050.</p>
