World can limit global warming to 1.5C by \u2018improving energy efficiency\u2019<\/a><\/h3>\n<\/div>\n<\/div>\n
\n

It is possible to limit global warming to 1.5C and achieve many of the sustainable development goals without \u201cnegative emissions technologies<\/a>\u201d, a new study finds.<\/p>\n

The research suggests that improving energy efficiency \u2013 chiefly by saving on everyday energy use \u2013\u00a0could play a major role in restricting warming to 1.5C above pre-industrial levels, which is the aspirational target of the Paris Agreement<\/a>.<\/p>\n

Emerging technologies, such as multipurpose smartphones and electric autonomous cars, could be key to improving energy efficiency both in the developed world and the global south, the lead author tells Carbon Brief.<\/p>\n

The \u201clandmark\u201d study provides policymakers with tools to implement strategies to rapidly increase energy efficiency, another scientist tells Carbon Brief.<\/p>\n

Negative emissions<\/h4>\n

Under the Paris Agreement, countries agreed that warming should be limited to \u201cwell below\u201d 2C above pre-industrial levels, with efforts to keep it below 1.5C. Since then, researchers have developed a range of scenarios to explore how this could be achieved.<\/p>\n

Until recently, scenarios limiting warming to 1.5C have typically relied<\/a> on the rapid and widespread deployment of negative emissions technologies (NETs).<\/p>\n

NETs<\/a> are a group of methods \u2013 many still in development \u2013 that would limit global warming by removing CO2 from the air and storing it on land, underground or in the oceans.<\/p>\n

In particular, most 1.5C scenarios assume that the world will develop large-scale bioenergy with carbon capture and storage (BECCS<\/a>). Put simply, BECCS involves burning biomass \u2013 such as trees and crops \u2013 to generate energy and then capturing the resulting CO2 emissions.<\/p>\n

The assumption that BECCS will be needed to reach 1.5C has proved controversial<\/a>among some groups. This is because BECCS has yet to be demonstrated at a commercial scale and research suggests<\/a> that deployment would take up large amounts of land, which could threaten food production and wildlife.<\/p>\n
