The price of NZUs has slid back noticeably since last week’s auction, as market observers note the healthy volumes traded in the lead up to the sale means the market is well-stocked.

Male players must step up and add their voice to the campaign to stop our sport being sold out to the big polluters causing climate change

At the Cop29 climate conference last month Sofie Junge Pedersen and Katie Rood again called for Fifa to drop its sponsorship deal with the Saudi Arabian state oil company Aramco. They were among more than 130 female players who signed an open letter in October that described the partnership as a “middle finger to women’s football” that will do real damage to people and our planet.

After the letter was published, I spoke out in support of their initiative. I hoped other professional male players would join me. The women were widely applauded for speaking out but their male counterparts have not followed suit. On Wednesday, Fifa is poised to confirm Saudi Arabia as the host of the 2034 men’s World Cup.

The quickest way to tell the difference between an eastern brown snake and a copperhead is to nearly step on it. If it strikes, it’s an eastern brown. If it stays still as you jump back, it’s a copperhead.

Thankfully, the snake I nearly stood on this week as I walked distractedly through the horse yard was a copperhead. Lowland copperheads are the seventh most venomous snake in Australia, but they are also shy and only bite when severely provoked. They are pretty common here in the Macedon Ranges. This is the second time I’ve nearly stepped on this particular snake. I also didn’t see it when carrying washing out to the line last month. Both times it skedaddled.

The Tokyo Stock Exchange will introduce two new trading categories for agricultural carbon credits under Japan’s J-Credit scheme, as it seeks to enhance market liquidity and efficiency amid increasing project registrations and certification volumes.

UN civil aviation body ICAO late on Friday published reports outlining its Technical Advisory Body’s (TAB) assessments, recommendations, and public comments made during the 2024 cycle for applications by carbon credit standards seeking eligibility under the airline offsetting programme.

Emitters in California's carbon market more than halved their use of offsets during the 2021-23 compliance period, driving overall utilisation under the scheme to below 4% despite an uptick in WCI partner Quebec, government data published Friday showed.

The US EPA’s power plant emissions rules were tested Friday before a three-judge panel as attorneys representing Republican states argued that the rules didn’t properly consider the costs of carbon capture and storage (CCS) technology and that the EPA overstepped in its rulemaking authority.

Emitters built their net holdings throughout the North American carbon markets, while financial players continued to shuffle their positions in California Carbon Allowances (CCAs) and RGGI Allowances (RGAs) in favour of V25s, data released Friday from the US Commodity Futures Trading Commission (CFTC) showed.

Europe may have made significant progress in decarbonising its energy sector, but investment efforts must more than double to an average of $1 trillion annually by 2030.

Brazil’s National Bank for Economic and Social Development (BNDES) this week solicited proposals under initiatives collectively worth R$109 million ($18 mln) that would support forest restoration in the Amazon and Atlantic Forest.

Oil derived from sugarcane is a promising alternative feedstock in the production of sustainable aviation fuel (SAF) given its land-use efficiency, but the process faces high production costs, researchers published in a recent study.

So-called "CDR optimisation" projects that build on pre-existing practices need to improve accounting techniques to distinguish between removed and avoided emissions in order to ensure integrity in the crediting process, representatives from a California-based research group told Carbon Pulse.

The Saskatchewan legislature unanimously passed legislation that will keep federal carbon pricing off of provincial home heating bills on Thursday following a year of political tussling with Ottawa over payment of the levy on fuel.
