A new British pet food brand has launched what it claims to be "the world's most sustainable dog food" made from oats, potato, kale, seaweed, chicory and insects. Pets are estimated to consume 20% of the world's meat and fish, according to pet food start-up Yora. Farming of animals – such as cattle – for food contributes to increased greenhouse gases in the atmosphere which contributes to climate change.

Today, surrounded by freezing temperatures, thousands of heads of lettuce grow, nestled in a cozy greenhouse fed by nutrient-rich nitrates. Or you could call it what it is: fish poop. The process, called aquaponics, allows farmers to grow local, organic produce anywhere at any time of year. Aquaponics is a sustainable method of farming that combines aquaculture (raising fish) and hydroponics (cultivating plants in water).

Here are some sites to check out, depending on what you want to dispose of and how you want to do it.

In efforts to curb our use of greenhouse gas-generating fossil fuels, plant-based biofuels are among the top contenders as alternative liquid energy sources for transportation. However, strategies to produce high yields of biomass for fuels are not a one-size-fits-all proposition, according to a study led by UC Santa Barbara professor of ecology David Tilman.

Oregonians recycled 2 billion glass bottles last year through its bottle deposit system, more than ever before. Recycling through the system reached a record-high rate of 90 percent in 2018, Oregon Public Broadcasting reported Monday. The 2018 rate marks a 26 point jump from just two years earlier, according to the report.

Global carbon dioxide emissions are expected to hit a record high in 2018, despite urgent calls from climate scientists and international groups such as the United Nations to cut back. Worldwide, fossil fuel use is projected to pump 2.7 percent more CO2 into the atmosphere in 2018 compared with 2017. Last year, such emissions contributed 9.9 gigatons of carbon. The data are presented in the Global Carbon Budget published online December 5 in Earth System Science Data. 2018 marks the second year in a row that the emissions, which fuel global warming, have risen substantially after a lull from 2014 to 2016.

For those of us who spent most of our lives painstakingly separating plastic, glass, paper and metal, single-stream recycling is easy to love. No longer must we…

To highlight the waste material from discarded electronic parts, artist Zayd Menk is building a small-scale model of London's Westminster area solely out of e-waste.

The past few months have seen a noticeable increase in individuals who are are becoming more environmentally aware regarding necessary changes they must make to reduce their impact on the planet. The results of which have seen more sustainable purchasing trends becoming prevalent, and companies are making alterations to suit those needs.

Vow to expand marginal-seats campaign against Coalition comes after ban on Clean Energy Finance Corporation from financing wind and small-scale solar

Unlike the Bank of England and Norway's massive wealth fund, Australia - vulnerable to both climate action and change - has no formal processes within its financial system for assessing climate risks.

The thoroughfares of Pyongyang feature the greatest amenities for the convenience and efficiency of the socialist worker.

United Airlines is partnering with California-based Fulcrum Bioenergy to make alternative jet fuel from food scraps, farm waste, and animal fat.

When transit is planned with the goal of high ridership, what does that mean? What do transit network designers actually do when this is their direction?

Good news: There’s still hope for truly sustainable farming.

After all these years I still get that little shiver of anticipation when I receive a request for a tender proposal titled “sustainability” or “ESD” – that’s my thing, my passion, my business, and I know I’m good at it.

As we noted in a sister article on Friday (“Climate Change Issues May Decide 2016 US Election”), NextGen Climate has come out with a thought-provoking white paper called “The Economic Case For Clean Energy.” Its context mirrors and supports the gist of remarks by Tom Steyer, president and 2013 founder of the group, that challenge American

It appears that New Zealand is finally ready to throw their domestic coal habit into Mount Doom — by 2018, the country will cease to use coal as a source of domestic energy production. “Historically coal has played an important role in ensuring the security of New Zealand’s electricity supply, particularly in dry years where our hydro-lake levels are low,” Simon Bridges, New Zealand’s Energy and Resources Minister, said in a statement.

Global manufacturer Skretting has extensively tested a fish food that is totally free of wild caught fishmeal.

Researchers looking into new and sustainable energy have achieved a breakthrough in solar cell technology by reporting the development of a “green antenna” to potentially double the efficiencies of certain solar cells and significantly, make them more affordable. Solar energy is a proven, inexhaustible source of energy and is slowly findings its way into communities.

The world could one day be powered by photosynthesis from artificial leaves, say researchers from Monash University in Melbourne. Their system to turn water into fuel, using nothing but solar energy, could be used to run cars, houses and even whole communities. The 'artificial leaf' created by researchers is actually more of a solar-powered device that is able to produce hydrogen with a record-breaking degree of efficiency.

Costa Rica has set an ambitious goal for itself: To be entirely carbon neutral by 2021. But it’s really not that crazy — just this summer, the entire country was powered entirely on renewable energy sources for 94 straight days.

New report spotlights the wildest lands that are most at risk of being exploited for the resources that lie beneath them. These lands are Too Wild to Drill.

Pioneering technology to deliver the cheapest, small-scale concentrated solar power plants in the world could revolutionise the renewable energy market

A key tool in the U.S. Clean Power Plan, wind gets global lift with lower costs and more offshore farms. But will its growth continue?

An unlikely partnership between Hawaii’s local government and the US military makes the island a leader in energy policy.

High on a hill was a lonely sunflower. Not a normal sunflower, mind you; that would hardly be very notable. This sunflower is a solar sunflower that combines both photovoltaic solar power and concentrated solar thermal power in one neat, aesthetic package that has a massive total efficiency of around 80 percent. The Solar Sunflower, a Swiss invention developed by Airlight Energy, Dsolar (a subsidiary of Airlight), and IBM Research in Zurich, uses something called HCPVT...

It has been more than four years since the east coast of Japan was hit with a trifecta: an earthquake of Magnitude 9 on the Richter scale, followed by a massive tsunami triggered by the quake’s tremors, and then the meltdown of three nuclear reactors in the Fukushima Daiichi nuclear generating complex.

According to U.S. government estimates obtained by the AP, if left unchecked, the Taylor Energy leak could continue to spill oil into the Gulf for at least another 100 years.
