Global carbon-pricing revenues reach record high - plus other top stories about global energy

As momentum grows for implementing energy transition measures like carbon taxes and Emissions Trading Systems (ETS), these 'polluter-pays' policy initiatives have produced record global revenues approaching the $100 billion milestone, the World Bank reports.

The 10th edition of the bank's annual State and Trends of Carbon Pricing report finds direct carbon-pricing instruments cover 23% of global greenhouse gas emissions, compared to just 7% a decade ago.

As the name suggests, a carbon tax adds a set fee that must be paid on each unit of carbon dioxide emissions.

ETS schemes are slightly different, as they limit the level of emissions a company can generate, enabling those with low emissions to sell their surplus allowance to heavy-emitting firms, in effect putting a tradable unit price on pollution.

Over the long term, the scheme should act as an incentive to reduce emissions and therefore costs, while generating funds which can help finance decarbonization efforts.

“Carbon pricing can be an effective way to incorporate the costs of climate change into economic decision-making, thereby incentivizing climate action,” said Jennifer Sara, Global Director for Climate Change at the World Bank.

“The good news from this report is that even in difficult economic times, governments are prioritizing direct carbon-pricing policies to reduce emissions. But to really drive change at the scale needed, we will need to see big advances both in terms of coverage and price," she said.

Uptake of carbon taxes and ETS initiatives are increasing in emerging markets, with countries like China, Malaysia, Viet Nam working to implement new schemes. However, high-income countries dominate when it comes to adoption of these instruments.

The International Energy Agency is forecasting global additions of renewable power capacity of as much as a third in 2023.

The IEA announced on 1 June that stronger policy and also concerns around energy security are combining to push increased deployment of clean energy.

Some 107 gigawatts are expected to be added this year - equivalent to more than the total power capacity of Germany and Spain combined, IEA Executive Director Fatih Birol said, with solar and wind driving much of this expansion.

Next year total renewable electricity capacity is expected to exceed the total power output of the US and China combined.

Russia's pipeline natural gas exports to the European Union fell nearly 15% in May compared to the previous month. Gazprom's supplies to the EU totalled 2 billion cubic metres (bcm) for the month, down from 2.3 bcm in April, Reuters calculates.

A $10 billion green hydrogen project in Namibia will proceed to the next phase, following an agreement between the government and developer Hyphen Hydrogen Energy. Once online, the project could export clean hydrogen energy to Europe.

Import tax on solar panels could be cut by half in India to help bridge the gap in a shortfall in local supplies. It could be reduced from 40% to 20% under the plans.

A new joint venture between EDF and Simply Blue Group to develop two wind farms off the Irish coast could generate enough electricity to power two million homes.

Investment in battery storage projects in Texas is booming, reports Reuters, with returns of around 20% helping drive interest.

Ukraine has announced it will increase its consumer energy tariffs to strengthen its energy system and to build resilience ahead of next winter. The country's energy system has been hit by months of Russian air strikes.

A German start-up has received funding of $7.5 million for a revolutionary fusion energy project. The project is not expected to come online until the 2030s.

South Korea and the European Union have agreed on a new partnership to work together on the green transition, in areas from sustainable finance to energy efficiency, and carbon capture, utilization and storage.

Scientists have developed a new - potentially more environmentally friendly - method to generate ammonia, a key ingredient in fertilizers and also a potential low-carbon fuel. Find out about the process, developed at Stanford, here.

Asia's green economy could have a transformative effect on the world in decades ahead, Ravindra Ngo, founder of the Asian Network, writes. To do so, stakeholder collaboration and the use of technology and innovation will be central.

Critical minerals are vital for much modern technology, particularly for electric vehicles, but a supply-demand mismatch is causing issues. At least five areas require urgent attention, write the authors.
