Plastic Soup Foundation (PSF), a Dutch nonprofit, and New York-based Parley for the Oceans announced Tuesday a partnership to tackle the issue of microfiber pollution and to create a global alliance of companies, governments, NGOs and scientists. Microfibers - tiny, often synthetic threads shed from laundry, industrial clothing manufacturing and fishing nets - have been found in alarming numbers in recent studies of microplastic pollution.

Four mechanical engineering students from Nashik have invented a device which is an indicator for the vehicle driver about excessive pollutant levels, while driving. When the engine of the vehicle starts, the sensor fitted in the silencer will sense the exhaust particles and check the limit value. If it exceeds the prescribed limit then a red light will blink as the first indicator, for two hours. Even after the first warning, if there is no change in the limit then there are two more indicators that will blink within a gap of two hours after which the engine will automatically turn off. According to the four inventors, the device will help in tackling the pollution issue, especially in densely-populated and polluted areas.

If you don't like lifeless hair, dandruff on your shoulders and plastics in your ocean, you can tackle all three in the shower. Procter & Gamble announced Thursday that its Head & Shoulders shampoo bottles will be recyclable and made of up to 25 percent "beach plastics," from trash removed from beaches, oceans, rivers and other waterways.

Shareholder proposals are an effective tool for driving companies to tackle environmental and ethical issues, according to new research. "Investors can be a driver for social responsibility and -- at least when focused on material issues -- can improve both societal and financial outcomes at the same time," writes George Serafeim.

At a congressional briefing last week, top executives from Ben & Jerry's, Clif Bar, Kellogg Company, Mars Incorporated, PepsiCo, Stonyfield and Unilever discussed how climate change is disrupting global food supplies and their own supply chains. They called on lawmakers to acknowledge the ways in which rising temperatures are impacting their businesses and to act swiftly to reach bipartisan solutions to tackle this threat.

Researchers in Iceland found a new way of tackling climate change by pumping carbon dioxide underground and turning it into stone.

The Roundtable on Sustainable Palm Oil has suspended its certification for Malaysian palm oil producer IOI Group amid concerns that the company has failed to live up to its obligation to tackle deforestation. The decision has already had a big impact on IOI, which has lost business with Unilever, Kellogg and Mars. "If IOI wishes to regain its customers, it must take immediate and significant action," says Greenpeace Indonesia campaigner Annisa Rahmawati.

The citizens of four major European countries think the impacts of climate change such as severe floods and storms are already affecting them, according to a major new polling study. The research dispels the idea that global warming is widely seen as a future problem, and also shows strong support for action to tackle global warming, including subsidies for clean energy and big financial penalties for nations that refuse to be part of the international climate deal signed in Paris in 2015 - as US president Donald Trump has threatened.

Plastics are an important part of the global economy and have many practical applications for everyday life, but their indisputable benefits are significantly outweighed by their environmental drawbacks - namely in regards to ocean pollution. Recognizing the seriousness of the problem, Dell, the Connecticut Department of Energy and Environmental Protection and NatureWorks are finding new and innovative ways to tackle plastic pollution both at the source and at end-of-life.

Ecolab CEO says, water must be priced now. Water stress is already creating economic challenges.

China is starting to get serious about tackling pollution and climate issues, and the fate of the rest of the world could depend on how good a job Beijing can do at mapping out a sustainable course for the future. "We need more of everything," says Chinese sustainability leader Peggy Liu. "Wind, solar, a modernized grid. We need to leapfrog over the past and into a clean-energy future."

China seeks a fair, global system to tackle climate change and will deliver its pledge to the United Nations by the end of Tuesday on how much it will cut emissions, Chinese Premier Li Keqiang said after talks with top European Union officials.

Rio de Janeiro became the first city in the world to fully comply with the Compact of Mayors. City leaders can achieve compliance by registering a commitment, identifying their municipality's current emissions, creating GHG reduction and adaptation targets, and establishing an action plan.

Conservation International's Business & Sustainability Council (PDF) examined the corporate risk and opportunities related to the energy-water-food nexus. Shell, Chevron and Coca-Cola have working solutions for the energy-food-water nexus.

By the end of the century, scientists say, megafires-conflagrations that chew up at least 100,000 acres of land-will become the norm. Which makes them of critical interest to researchers. These infernos, once rare, are growing to sizes that U.S. Forest Service Chief Tom Tidwell describes as "unimaginable" two decades ago. Five alone have consumed more than five million acres in central Alaska since June. Washington, Oregon, California, Arizona, New Mexico and Colorado also experienced their worst wildfires in the past seven years.

Rising temperatures are increasing the number of "megafires" in the forests of the western U.S., experts say. Tackling and preventing such fires could require a significant shift in firefighting and forest conservation strategies. "These stresses are going to become more widespread," warned Craig Allen, a U.S. Geological Service forest ecologist. National Geographic News (free registration) (8/9) 

The 17 Global Goals (also known as the Sustainable Development Goals or SDGs) launched late last month by the United Nations (UN) aim to achieve three main objectives in the next 15 years: end extreme poverty; fight inequality and injustice; and tackle climate change. Since the launch, various companies and leaders have pledged to do their part to achieve the goals; now, the latest push is to build worldwide public awareness of the goals through various efforts to "tell everyone" (#TellEveryone), including support from scores of celebrities:

Carnival Corporation & plc (NYSE/LSE: CCL; NYSE: CUK), the world's largest travel and leisure company, today launched a new brand called fathom™, defining a new travel category it is calling "social impact travel," that will offer consumers authentic, meaningful impact travel experiences to work alongside locals as they tackle community needs

ExxonMobil is to become the first fossil-fuel giant to report on threats to its oil and gas assets due to possible future regulation of carbon emissions. The move won plaudits from clean-energy campaigners, who say fossil fuels will become economically unviable as governments tackle carbon emissions. "That the largest American oil and gas company is the first to come to the table on this issue says a lot about the direction that energy markets are taking," says Danielle Fugere, president of As You Sow

A new technology called bio-energy with carbon capture and storage, or BECCS, could potentially eliminate the equivalent of China's total carbon emissions from the planet's atmosphere, dramatically slowing the rate of climate change, according to a draft U.N. report. The system, which involves capturing and burying carbon emissions from burning biomass, has not yet been tested at scale but is increasingly seen as "an essential component" of any effort to tackle climate change, the report notes.
