Scientists investigating marine life in the Baltic Sea have found mussels, oysters and clams are emitting greenhouse gases – but cows still trump them

Swedish scientists have found that flatulent shellfish are creating vast amounts of greenhouse gases, leading to a predictable slew of comments about farting cockles and clams. But beneath the schoolboy humour, there is a serious point. The two gases in question – methane and nitrous oxide – are potent agents of climate change, with a warming potential 28 and 265 times greater than carbon dioxide respectively.

Scientists studying the Baltic Sea off the coast of Sweden have found that shellfish are producing one-tenth of all the greenhouses gases released there – the equivalent to the amount produced by 20,000 cattle. If the same situation is being replicated around the rest of the world’s seas and oceans, we have a serious problem.

Coal can’t compete with cheaper clean energy. The Trump administration can’t save expensive, dirty energy.

Last week, Trump’s EPA administrator Scott Pruitt announced, “the war on coal is over.” If there ever was a war on coal, the coal industry has lost. According to a new report from the Union of Concerned Scientists, many old American coal power plants are being retired or converted to natural gas, and new coal power plants aren’t being built because they’ve become more expensive than natural gas, wind, and solar energy:

The share of US electricity coming from coal fell from 51 percent in 2008 to 31 percent in 2016—an unprecedented change. New UCS analysis finds that, of the coal units that remain, roughly one in four plans to retire or convert to natural gas; another 17 percent are uneconomic and could face retirement soon.

WWF analysis reports that 40% of rivers are polluted with sewage that can harm wildlife and put human health at risk

Raw sewage is flowing into rivers at thousands of sites across England and Wales, a report has warned, harming wildlife and putting human health at risk.

The total amount of raw sewage intentionally being put into rivers is unknown, which is a “huge concern”, according to conservation group WWF, which produced the analysis. The available data suggests that more than half of overflow sites spill sewage into rivers at least once a month and 14% at least once a week.

It's beginning to look like the Federal Government is walking away from the Clean Energy Target proposed by Chief Scientist Dr Alan Finkel.

Electric cars won’t eradicate gridlocks and air pollution, but carbon footprints could be cut by favouring pedestrians, cyclists and mass transit

The spectre of our cities choking with unhealthy air has prompted numerous governments to mandate a transition to electric cars. Their concerns are well founded, even if their proposals fall short of what is needed.

Over the past four decades, cars have become far less polluting. Their fuel efficiency has practically doubled and their tailpipe emissions have been reduced by more than 95%. Yet cities such as London and Paris are still battling smog and pollution. California has for decades demanded the toughest emission standards in the US, and yet Los Angeles heads the list of US cities for bad air quality. Moving to all-electric car fleets will be a positive step, albeit an inadequate measure.

Georgetown mayor Dale Ross is ‘a good little Republican’ – but ever since his city weaned itself off fossil fuels, he has become a hero to environmentalists

When the caller said he worked for Harry Reid and the former Senate majority leader wanted a word, Dale Ross assumed it was a joke. “OK, which of my buddies are messing with me today?” he wondered.

He shouldn’t have been so surprised. Ross is the mayor of Georgetown, population 65,000, and he has become a minor celebrity in environmental circles as a result of a pioneering decision in 2015 to get all the city’s electricity from renewable sources.

Pret A Manger becomes the latest to act by offering free filtered water and selling empty glass bottles

A growing number of outlets selling food and drink in the UK are taking action to ditch plastic amid deepening concern about its effect on the environment, with drinking straws and bottles among items being phased out.

Pret A Manger has become the latest to take action, announcing that it has installed taps dispensing free filtered water and started selling empty glass bottles in its three vegetarian stores. The scheme is due to be rolled out to branches in Manchester from the end of October.

Is Australia undervaluing its most valuable natural asset by only charging $6.50 a day to visit the Great Barrier Reef? And would it help if tourists were asked to pay more?

China’s decarbonization boat stayed in harbour this year but the winds of change continue to blow.

In the wake of this year's Bridgestone World Solar Challenge, the global race to bring solar PV integrated EVs to market is hotting up. And Australia is a key contender.

New study highlights billions of dollars saved through rooftop solar installations, as ACCC defends manipulation of markets by major generators as "rational behaviour", says nothing can be done about "gold plating" of networks, and argues against measures to encourage more renewables.

Yates, Corbell team up to create new renewable energy investment fund that will write contracts and tap into huge pipeline of wind, solar, storage projects.
