Australia's NEM emissions reductions are accelerating, but how long until the grid is fully decarbonised?

Large US industrial timber companies are beginning to embrace reforestation through carbon finance, leaving small forest owners and government agencies key to scaling up offset efforts, a conference heard Wednesday.

Large stationary installations regulated under Canada’s ‘backstop’ output-based pricing system (OBPS) will likely not use any Alberta offsets for compliance against 2020 emissions, as higher prices and political risk make such purchases difficult, a panel heard Wednesday.

California regulator ARB issued roughly 63,000 new compliance offsets to two livestock projects this week, while Quebec divvied out over 40,000 credits for use in its cap-and-trade programme, according to data published Wednesday.

Carbon capture and storage (CCS) of various types is technologically ready to be deployed at scale but needs streamlined permitting, increased tax incentives, and broad public outreach to do so, a conference heard on Wednesday.

A bipartisan group of Senators approved a resolution on Wednesday that would nullify Trump-era regulations on methane emissions for the oil and gas sector, effectively reimposing Obama-era rules that sought to cut output of the climate-warming pollutant.

I’ve seen lots of demergers and most have been more or less successful at creating value. AGL’s effort so far is a case study in how to stuff it up.

The post Past, present and future: AGL is making a mess of its clean energy transition appeared first on RenewEconomy.

Dominion Energy argued its auction-centric RGGI procurement strategy is a prudent approach to meet compliance obligations at a electricity rate hearing Wednesday, while adding the Virginia-based utility is also working on a multi-year secondary market purchase to cover CO2 output.

Utility RWE reported a 33.5% year-on-year rise in its EU ETS-covered thermal generation in Q1, the company said on Wednesday, boosting the carbon demand of one of the market’s biggest buyers.

Australian scientists say shading reef and controlling coral-eating starfish can only be effective if strong action is taken to reduce emissions

Shading corals and deploying more heat-resistant species across the Great Barrier Reef on an as-yet untested scale could buy the world heritage site another two decades, according to a study led by Australian government scientists.

The scientists said combining “life support” interventions such as cloud brightening – which involves spraying sea water to make low-altitude clouds more reflective – with better management of a coral-eating starfish could help delay “precipitous declines” caused by global heating.

The British government on Wednesday set out the eligibility criteria for participation in its carbon allowance auctions, which are scheduled to kick off next month.

The EU’s objective to go beyond net zero emissions after 2050 highlights the need for a policy on carbon removals, as the European Commission prepares two key legislative proposals to compensate for and certify carbon sinks.

Glacier melt contributing more to sea-level rise than loss of Greenland and Antarctic ice sheets, say experts

The melting of the world’s glaciers has nearly doubled in speed over the past 20 years and contributes more to sea-level rise than either the Greenland or Antarctic ice sheets, according to the most comprehensive global study of ice rivers ever undertaken.

Scientists say human-driven global heating is behind the accelerating loss of high-altitude and high-latitude glaciers, which will affect coastal regions across the planet and create boom-and-bust flows of meltwater for the hundreds of millions of people who live downstream of these “natural water towers”.

EUAs extended their all-time high on Wednesday, breaking above €48 amid rising energy prices, surging investor interest, and as buyers approached their last possible moment to cover 2020 compliance.

A $40/tonne carbon price and a bump in variable renewable energy capacity could shave a quarter off CO2 emissions from Thailand’s power sector by the end of the decade, according to the International Energy Agency (IEA).
