NEW DELHI, Feb. 28 -- The timelines for peak fossil fuel consumption-including oil and coal in both India and globally-may be delayed further amid geopolitical tensions that are pivoting the focus towards energy security and countries deviating from their climate commitments, Shell plc's chief economist Mallika Ishwaran said. While decarbonization in road transport is under way, there is little progress in aviation, marine and steel, which would delay the energy transition journey and eventually, peak oil timelines, Ishwaran said in an interview. "We are seeing oil persisting. Electrification of road transport happens anyway, and that displaces anywhere between 40% to 60% of oil demand in road transport, so that's the significant displacement. But what we don't see is displacement in the hard-to-abate sectors. Aviation, marine, even in the [heavy] industry, that is really sticky and difficult to move, unless you have a lot of policy effort and intent," she said. Peak fossil fuel consumption is the point at which global demand for coal, oil and natural gas reaches its maximum level and begins to plateau or decline. It is considered a prerequisite for achieving the goals of the Paris Agreement, which seeks to reduce greenhouse gas emissions and limit global warming. According to Shell's 'Archipelagos' and 'Surge' scenarios, which reflect current global pressures, peak oil is expected in the early 2040s in India and globally, a few years before that in the 2030s, Ishwaran said, citing the company's report on oil market projections, titled 'India's energy transition in a security-focused age,' released on Thursday. Several estimates including those by the International Energy Agency had projected peak oil globally by 2030 and in India in the mid-to-late 2030s....
