On 5 October the climate convention (UNFCCC) secretariat states that the threshold for entry into force of the Paris Agreement was achieved. This follows receipt of instruments of ratification of the EU and Canada. The Paris Agreement consequently enters into force a month later on 4 November. The speed at which countries ratified the agreement was unprecedented in international treaty-making history. To enter into force, at least 55 countries accounting for at least 55% of global GHG emissions were required. National action plans will now formally become Nationally Determined Contributions (NDCs). On 25 October the International Energy Agency (IEA) reports that renewables have overtaken coal as world’s largest source of power capacity. With falling costs of renewable supplies, the IEA revised its 5-year forecast to suggest renewables’ capacity will grow 13% more than estimated in 2015.
