Premier Kathleen Wynne said Ontario's long-term plans to combat climate change are "optimistic and entirely realistic" on Tuesday.

The province wants to achieve an 80-per-cent reduction in emissions over 1990 levels by 2050. Wynne said to do that, the province will work on a range of projects, from getting more electric cars on the roads to changing the building codes to create more environmentally-friendly buildings.

However, a five-year "action plan" that will outline some of the first major steps the province will take won't be released until the new year.
