Ambitious emissions-reduction goals are important, because they allow policymakers to coordinate and focus efforts on a defined target. But the problem with setting lofty goals is that, eventually, they must be met. The German government is now finding out how difficult that can be.

Exhaust emissions from gasoline and diesel cars get a lot of attention from policymakers attempting to combat climate change. But another very large source of carbon emissions has nothing to do with transportation. Emissions of methane have increased dramatically over the past few years, with livestock raised for human food as the largest source... 
Global efforts to reduce greenhouse-gas emissions may be starting to pay off, suggests a recent study. Last month, scientists released an assessment that suggests global carbon emissions did not increase significantly in 2016. That makes this the third year in a row that carbon emissions have remained flat. DON'T MISS: Renewable energy growth... 
When it comes to green cars, California leads the nation—and has done so for decades. California residents buy more hybrids and electric cars than those of any other state, and it is also the only state with fueling infrastructure to support the sale of hydrogen fuel-cell vehicles. Consumer enthusiasm is underpinned by strict regulations... 
It's been 15 months since news broke that VW Group had used "defeat device" software in its diesel cars and SUVs that let them emit far more than permitted levels of nitrogen oxides in real-world use. Even now, however, the Volkswagen diesel scandal continues to grow new tentacles as investigators uncover additional apparent instances of... 
The Volkswagen diesel scandal has led to numerous lawsuits against the German automaker in multiple countries. But now regulatory agencies in European countries have become caught up in the legal fallout from VW's emissions cheating. The European Union began legal action Thursday against Germany, the U.K., and five other nations. DON'T MISS: Every... 
African nations have a very specific problem when it comes to dealing with emissions from diesel vehicles. Because of lax emissions standards, traders import fuel to these countries that is too dirty for sale elsewhere. But now a handful of African nations are taking a stand against this.

A week ago, the EPA recommended that U.S. vehicle emission standards stay put for the years 2022 through 2025. According to the Technical Assessment Report the agency issued in July, automakers have so far quite successfully met standards in place since 2012 to cut emissions of the climate-change gas carbon dioxide. And, the report concluded, they... 
Last week, the U.S. Environmental Protection Agency ruled that existing emissions limits for passenger cars for 2022 through 2025 should remain in place. It's a decision that is already opposed by lobbyists representing the auto industry, and possibly by the incoming Trump Administration. Sure enough, one automaker says it has already begun talks... 
This week, the U.S. Environmental Protection Agency (EPA) said it would maintain current Corporate Average Fuel Economy (CAFE) standards for 2022 to 2025. The decision was praised by environmental groups, but likely won't receive as warm a reception from the industry. CAFE standards are up for a midterm review, and auto-industry lobbyists spent...
