New Zealand is likely to be severely short on NZUs after 2030 unless emissions start to rapidly decline, a forestry expert told a panel discussion Wednesday.

A group of conservation organisations have filed a suit against the Tennessee Valley Authority (TVA), asking a federal court to halt efforts by the nation's largest public utility to replace a retiring coal installation with a natural gas-fired power plant.

It’s not surprising that consumers would like to install PV, batteries, efficient appliances and smart management, as well as upgrading their homes’ thermal efficiency, to defend against the madness of energy markets.

The voluntary carbon market (VCM) will continue attracting adjacent government regulations related to credit transparency and trading behaviour without fully regulating the market, offset experts said during a Wednesday webinar.

A Canadian advisory firm intends to roll out its tech solution that monetises EV credits earned through the country’s nascent Clean Fuels Regulations (CFR) to US jurisdictions with existing and planned electrification programmes.

The US Supreme Court issued a decision on Wednesday denying the applications of Republican states, power companies, and industry groups to stay federal laws restricting CO2 emissions from power plants.

River restoration can increase storage of CO2 but it is not yet a viable option for generation carbon credits due to significant uncertainties around measuring and maintaining carbon levels in dynamic river ecosystems, a new study has warned.

Landmark review says urgent action needed to conserve resources and save ecosystems that supply fresh water

More than half the world’s food production will be at risk of failure within the next 25 years as a rapidly accelerating water crisis grips the planet, unless urgent action is taken to conserve water resources and end the destruction of the ecosystems on which our fresh water depends, experts have warned in a landmark review.

Half the world’s population already faces water scarcity, and that number is set to rise as the climate crisis worsens, according to a report from the Global Commission on the Economics of Water published on Thursday.

Around 35% of installations have exited the EU ETS since its inception, while a further 16% have stopped operating, according to a new analysis.

Temperature and soil moisture play a critical role in shaping the wood density of trees, which in turn acts as key factor in determining forest carbon stocks, a new study has found.

Emergency requests by 27 states to pause rule requiring fossil fuel-powered plants to reduce emissions were denied

The US supreme court declined on Wednesday to put on hold a new federal rule targeting carbon pollution from coal- and gas-fired power plants at the request of numerous states and industry groups in another major challenge to Joe Biden’s efforts to combat the climate crisis.

The justices denied emergency requests by West Virginia, Indiana and 25 other states – most of them Republican-led – as well as power companies and industry associations, to halt the Environmental Protection Agency (EPA) rule while litigation continues in a lower court. The regulation, aimed at cutting greenhouse gas emissions that drive the climate crisis, took effect on 8 July.

Research suggests the marine animals are inhaling pollutants when they come up for air, with even rural populations affected

Microplastics have been found in dolphin breath for the first time, according to a study that suggests the marine mammals are inhaling the potentially harmful contaminants when they come up for air.

The US research team, whose preliminary findings are published in the journal, Plos One, are concerned about the potential impact of inhaled plastics on the animals’ lungs.
