The Ministry of the Environment, Conservation and Parks is an Ontario government ministry responsible for protecting and improving the quality of the environment in the Canadian province of Ontario, as well as coordinating Ontario's actions on climate change. This includes administration of government programs, such as Ontario's Drive Clean and Clean Water Act. The ministry headquarters are located inside the Ontario Government Buildings. History The Ministry of the Environment was originally established as a portfolio in the Executive Council of Ontario (or provincial cabinet) in 1972. The ministry was merged with the Ministry of Energy to form the Ministry of Environment and Energy from 1993 to 1997, and briefly again in 2002, before being split back up again. Following the 2014 Ontario election, the addition of climate change to the ministry's portfolio was announced on June 24, 2014, and its name changed from the Ministry of the Environment to the Ministry of the Environment and Climate Change. Following the 2018 Ontario election, the Ministry's name was changed from the Ministry of the Environment and Climate Change to the Ministry of the Environment, Conservation and Parks on June 29, 2018. Responsibilities Air Quality The MECP works to improve air quality through legislation, targeted programs, and partnership agreements with other neighbouring airsheds. This includes using a network of air quality stations that provide real-time air pollution data. The ministry communicates air quality to the public by providing an Air Quality Index based on ambient levels of ozone, fine particulate matter, nitrogen dioxide, carbon monoxide, sulphur dioxide, and total reduced sulphur compounds. Brownfields MECP is responsible for administering Ontario Regulation 153/04 which requires, under specific circumstances, a Record of Site Condition (RSC) to be submitted to the Ministry for acknowledgement. A RSC contains Environmental Site Assessments that ascertain the current condition of a site, including whether contamination exists on-site. The RSC is required when a property owner is choosing to change the property use from a less-sensitive to more-sensitive use (Example: Industrial Use to Residential Use) and is often required by the municipality's Chief Building Official before approval of a building permit. Climate change The ministry released a climate change action plan in 2007, setting greenhouse gas reduction targets for the province. It is the aim of the provincial government to reduce its emissions to: 6% below 1990 levels by 2014; 15% below 1990 levels by 2020; and 80% below 1990 levels by
