Dec 11 (Reuters) - Canada plans to steadily ramp up its price on carbon, reaching C$170 ($132) per tonne by 2030 from C$30 now, as part of its plan to fight climate change, the Liberal government said on Friday. Here are some details of the updated climate plan: *Ottawa said it would “strengthen” its approach to reducing methane emissions from the oil and gas sector by establishing new targets for 2030 and 2035. It gave no details. *The government said it would consider “climate risks and opportunities, including achieving net-zero emissions by 2050” in reviews of major projects. *Ottawa said it would invest C$1.5 billion to increase the production and use of low-carbon fuels such as hydrogen and renewable natural gas and diesel. *It also said it would introduce a hydrogen strategy by year end. *An innovation fund would provide C$3 billion over five years to support clean technology development, with a focus on the aerospace and auto industries, and efforts to develop a supply chain for electric vehicle batteries. *The government said it aimed to develop a “battery ecosystem” from mineral extraction and processing, to research and design, to manufacturing and recycling. *A pledge to deliver on Canada’s G20 commitment to phase out fossil fuel subsidies by 2025. *The scope of a proposed Clean Fuel Standard has been narrowed to cover only liquid fossil fuels, like gasoline, diesel and oil, which are mainly used in the transportation sector. *The Canada Infrastructure Bank has committed to invest C$2.5 billion in clean power projects over the next three years.
