This is a list of notable events relating to the environment in 2000. They relate to environmental law, conservation, environmentalism and environmental issues.
The Tisza, Tysa or Tisa, is one of the major rivers of Central and Eastern Europe. It was once called "the most Hungarian river" because it used to flow entirely within the Kingdom of Hungary. Today, it crosses several national borders.
Baia Mare is a municipality along the Săsar River, in northwestern Romania; it is the capital of Maramureș County. The city lies in the region of Maramureș, a subregion of Transylvania. It is situated about 600 km (373 mi) from Bucharest, 70 km (43 mi) from the border with Hungary, and 50 km (31 mi) from the border with Ukraine.
Gold cyanidation is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction. Cyanidation is also widely used in the extraction of silver, usually after froth flotation.
Orica Limited is an Australian-based multinational corporation that is one of the world's largest providers of commercial explosives and blasting systems to the mining, quarrying, oil and gas, and construction markets, a supplier of sodium cyanide for gold extraction, and a specialist provider of ground support services in mining and tunnelling.
The Săsar is a right tributary of the river Lăpuș in Maramureș County, Romania. It discharges into the Lăpuș in Bozânta Mare, southwest of Baia Mare. It is a medium-size river which flows through the cities of Baia Sprie and Baia Mare. Its length is 31 km (19 mi) and its basin size is 306 km2 (118 sq mi).
Roșia Montană is a commune of Alba County in the Apuseni Mountains of western Transylvania, Romania. It is located in the Valea Roșiei, through which the small river Roșia Montană flows. The commune is composed of sixteen villages: Bălmoșești, Blidești, Bunta, Cărpiniș (Abrudkerpenyes), Coasta Henții, Corna (Szarvaspatak), Curături, Dăroaia, Gârda-Bărbulești, Gura Roșiei (Verespataktorka), Iacobești, Ignățești, Roșia Montană, Șoal, Țarina, and Vârtop (Vartop).
The Martin County coal slurry spill was a mining accident that occurred after midnight on October 11, 2000, when the bottom of a coal slurry impoundment owned by Massey Energy in Martin County, Kentucky, broke into an abandoned underground mine below. The slurry came out of the mine openings, sending an estimated 306 million US gallons of slurry down two tributaries of the Tug Fork River. By morning, Wolf Creek was oozing with the black waste; on Coldwater Fork, a 10-foot-wide (3.0 m) stream became a 100-yard (91 m) expanse of thick slurry.
Stéphanie Danielle Roth is a French-Swiss environmental campaigner working on environmental, heritage and social issues with a focus on mining and farming.
Romania ranks tenth in the world in terms of the diversity of minerals produced in the country. Around 60 different minerals are currently produced in Romania. The richest mineral deposits in the country are halite.
The Kingston Fossil Plant coal fly ash slurry spill was an environmental and industrial disaster that occurred on December 22, 2008, when a dike ruptured at a coal ash pond at the Tennessee Valley Authority's Kingston Fossil Plant in Roane County, Tennessee, releasing 1.1 billion US gallons of coal fly ash slurry. The coal-fired power plant, located across the Clinch River from the city of Kingston, used a series of ponds to store and dewater the fly ash, a byproduct of coal combustion. The spill released a slurry of fly ash and water which traveled across the Emory River and its Swan Pond embayment onto the opposite shore, covering up to 300 acres (1.2 km2) of the surrounding land. The spill damaged multiple homes and flowed into nearby waterways including the Emory River and Clinch River, both tributaries of the Tennessee River. It was the largest industrial spill in United States history.
The 2000 Baia Mare Cyanide spill was a leak of cyanide near Baia Mare, Romania, into the Someș River by the gold mining company Aurul, a joint-venture of the Australian company Esmeralda Exploration and the Romanian government.
An industrial accident at a caustic waste reservoir chain took place at the Ajkai Timföldgyár alumina plant in Ajka, Veszprém County, in western Hungary. On 4 October 2010, at 12:25 CEST (10:25 UTC), the northwestern corner of the dam of reservoir number 10 collapsed, freeing approximately one million cubic metres of liquid waste from red mud lakes. The mud was released as a 1–2 m (3–7 ft) wave, flooding several nearby localities, including the village of Kolontár and the town of Devecser. Ten people died, and 150 people were injured. About 40 square kilometres (15 sq mi) of land were initially affected. The spill reached the Danube on 7 October 2010.
Roșia Montană Project was a proposed gold and silver mine in Roșia Montană, Romania. If approved, it would have become Europe's largest open-pit gold mine and it would have used the gold cyanidation mining technique. The project met with widespread protests in 2013 that indefinitely delayed the project, which saw its end in 2021, when Roșia Montană became a part of the UNESCO World Heritage list and was also included in the List of World Heritage in Danger. Following these measures, any mining activity in Roșia Montană is prohibited in the future.

This is a list of notable events relating to the environment in 1996. They relate to environmental law, conservation, environmentalism and environmental issues.
A gold cyanidation ban refers to the legislation that bans mining gold through the gold cyanidation technique.
Gold cyanidation is a chemical process for extracting gold from low-grade ore. Used in Romania for decades, the process came into debate following the 2000 Baia Mare cyanide spill and proposal of the Roșia Montană Project, which would create the largest operation for gold extraction using cyanides in Europe.
The Mariana dam disaster, also known as the Bento Rodrigues or Samarco dam disaster, occurred on 5 November 2015, when the Fundão tailings dam at the Germano iron ore mine of the Samarco Mariana Mining Complex near Mariana, Minas Gerais, Brazil, suffered a catastrophic failure, resulting in flooding that devastated the downstream villages of Bento Rodrigues and Paracatu de Baixo, killing 19 people. The extent of the damage caused by the tailings dam collapse is the largest ever recorded with pollutants spread along 668 kilometres (415 mi) of watercourses.
