With several starts and stops over the last 20 years or so, hydrogen fuel cell vehicles (FCVs) are finally hitting the roads.

The real competition for green tech is not other green tech, but the old, dirty incumbents.

A new patent filing suggests that the tech giant has fuel cells in mind for future computers and gadgets.

They are not efficient, there is no infrastructure, and they are shills for the fossil fuel industry.

In a bid to highlight the clean air advantage of the Toyota Mirai, a hydrogen fuel cell electric car, the company is putting up pollution-scrubbing billboards.

As salinization impacts agriculture around the world—another effect of climate change that will hit already-vulnerable places and people the hardest—farmers, small-scale farmers in particular, have to figure out how to

This integrative technology keeps CO2 out of the atmosphere and makes geothermal energy widely available

People want big SUVs and pickups, not little fuelsippers. What's a car maker to do?

Because America needs more SUVs and pickup trucks to be great again

That's what a lot of people are saying as new pollution rules for 2020 get closer.

Conservationists are celebrating a British firm's recent pullout from a biofuel project in Kenya that they say would have destroyed the Tana River Delta, a wetland ecosystem crucial for regional wildlife.

This waste-to-resource project not only produces a less smoky and long-burning fire, but could also help improve health and sanitation outcomes.

The debate over the true ecological sustainability of biofuels, the effects on global food prices, and their oft-heard claims of carbon-neutrality has been played out on TreeHugger in great detail. Adding a new

The technology could lead to cheaper hydrogen cars in the future.

It wasn't too long ago that biofuels were basking in the glow of nearly everyone's approval - a quick fix for reducing CO2 emissions from transport. The EU aims to fill 10% of its transport needs with biofuels by 2020. But biofuel's easy ride may be
