<p>Bosnian authorities have ordered the Balkans' leading metallurgical coke producer to halt operations to prevent major environmental damage. The company has been accused of discharging toxic liquid waste into a nearby river, and has not renewed an environmental permit that expired in January 2017 despite sanctions being imposed. The regional prosecutor's office has opened an investigation into whether the company is guilty of negligence.

<p>Starting September 1, halogen light bulbs will be banned across Europe in an effort to reduce emissions and energy bills by switching to light-emitting diodes (LEDs). LEDs consume one-fifth of the energy of halogen bulbs, which means the phase-out of halogen bulbs will prevent more than 15 million tons of carbon emissions a year. The phase-out will occur gradually, allowing remaining stocks of halogen bulbs to be sold and exempting capsules, linear, and low-voltage incandescents used in oven lights.

<p>Australia's outgoing Prime Minister, Malcolm Turnbull, removed requirements from the National Energy Guarantee plan for reducing greenhouse gas emissions due to insufficient parliamentary support. The requirements would have mandated that greenhouse gas emissions from the country's power industry be reduced by 26 percent from 2005 levels by 2030. Opponents of the requirements argued that reducing emissions would put the country at an economic disadvantage after the United States withdrew from the Paris Climate Accord.
