Following through on their commitment to bring emissions from electricity generation to net zero in the 2030s, leading industrialised nations can spur decarbonisation in other economies and sectors.

WWF and British Antarctic Survey (BAS) are seeking the public’s help to search for walrus in thousands of satellite images taken from space, with the aim of learning more about how walrus will be impacted by the climate crisis. It’s hoped half a million people worldwide will join the new ‘Walrus from Space’ research project, a census of Atlantic walrus and walrus from the Laptev Sea, using satellite images provided by space and intelligence company Maxar Technologies’ DigitalGlobe.

The Biden administration has unveiled plans to expand offshore wind energy in a move that could see turbines built along much of the US coastline.

With emissions, climate disasters and energy market volatility all rising, governments need to send an unmistakeable signal of clean energy ambition and action at COP26 to accelerate the transition.

The technology roadmap lays out clear pathways towards more sustainable ammonia production.

A new international push is needed to bring down methane emissions from fossil fuel operations – particularly oil and gas – where leaks can often be prevented easily at little or no cost.

The technology group Wärtsilä has issued a report ahead of COP26, the UN’s Climate Change Conference to be held in Glasgow, Scotland, this autumn, demonstrating the environmental and economic opportunities for states that decarbonise rapidly. The report will be presented at the Economist Sustainability Week event on 6 October.

GE Renewable Energy’s Haliade-X prototype in Rotterdam, the Netherlands, has started operating at 14MW, making it the first player in the industry to use a wind turbine at this power output.

Investment is increasing in hydrogen projects to support the clean energy transition, but further efforts are needed to reduce costs and encourage wider use across sectors.
