Switching up our building materials could store more than 16 billion tonnes of CO2 annually, according to a new study in Science A team of US researchers calculated that fully replacing conventional building materials in new infrastructure with CO2-storing alternatives could store as much as 16.6 billion tonnes of CO2 each year—roughly half of human-caused CO2 emissions in 2021.

Investment in marine and coastal conservation has traditionally been looked after by taxpayers, ratepayers, or community groups – but a changing climate and ongoing biodiversity decline have led to a financing gap, where there is simply not enough money to protect or restore marine ecosystems and maintain their economic return, Sustainable Seas says echo adrotate_group(33, 0, 0, 0); That’s why different pathways for funding are needed to support and scale business and restorative activities that are environmentally sustainable and align with community and iwi needs.

Experts have concerns about the government’s plans to introduce a standalone Act which will allow major infrastructure projects to bypass lengthy resource consenting processes, whilst it works on a full replacement for the Resource Management Act echo adrotate_group(33, 0, 0, 0); Cabinet has agreed that its new fast-track consenting regime will consist of: A new fast-track process contained in a standalone Act, with its own purpose statement focused on economic development; A priority for regionally and nationally significant infrastructure and development projects; A process for projects to be referred by Ministers into the fast-track process if it meets appropriate criteria; A list of projects that will be first to have their consents approved and conditions set by an Expert Panel; A process where referred projects will go to an Expert Panel which will apply any necessary conditions to ensure adverse effects of the project to the environment are managed appropriately, and where the panel will have only a limited ability to decline a project once referred.

Instead of fossil fuel emissions dropping sharply and rapidly this year, which was needed to ease climate change, the latest Global Carbon Budget is calling 2023 the worst year yet echo adrotate_group(33, 0, 0, 0); Global emissions from fossil use in 2023 are projected to hit a record high of 36.8 billion tonnes, rising 1.1%.

A major earthquake is likely to occur on the South Island’s Alpine Fault in the next 50 years – predicting when or where is not currently possible, but a recent study suggests large earthquakes can give off seismic signals months to years beforehand echo adrotate_group(33, 0, 0, 0); Unique seismic signals may be detected months to years before some large earthquakes, such as those preceding the 2023 magnitude 7.8 Kahramanmaraş Earthquake in Türkiye and also strongly felt in Syria, suggests a Nature Communications paper.

The window is fast closing for us to cut carbon emissions and reduce the severity of global warming, a new study finds echo adrotate_group(33, 0, 0, 0); The amount of carbon that humans can still emit, while also limiting warming to 1.5 °C relative to pre-industrial levels, may be exhausted within the next 6 years, suggests a study published in Nature Climate Change.

The loss of fossil fuel assets would have a minimal impact on the general populace, with most financial losses being borne by the most wealthy, researchers report in the journal Joule echo adrotate_group(33, 0, 0, 0); One common rationale against climate action is that the resulting fossil fuel investment losses could impact people’s retirement or long-term savings.  Continue →

The Government is consulting on four options for a better Emissions Trading Scheme, yet University of Otago Dr Sebastian Gehricke points out two of them will not even achieve New Zealand’s climate goals while the other two are not much better echo adrotate_group(33, 0, 0, 0); Four options for ETS reform are on the table, to avoid scenarios where it is cheaper for polluters to buy carbon credits – encouraging excessive tree planting – than to reduce their emissions.
